Texto completoThe patterns of development are key to understanding the origin of phenotypic diversity. Here, we described, for the first time, the embryogenesis of a Heliconius species. In Heliconius erato phyllis, the analysis of the embryonic pattern, from the blastoderm formation to the pre-hatching larva, was consistent with the long germ band embryos; which agrees with the phylogenetic trend of Lepidoptera. The second purpose of this thesis was to analyze the development of the color pattern in H. erato phyllis wings. We described the ontogeny of pigmentation, the microstructure, morphogenesis and maturation rates of the black, yellow, red, silvery and brownish scales - emphasis was given to the silvery and brownish scales, which were never taken into account in the literature. As for the black, yellow and red scales, they showed each a unique type of microstructure, while the silvery and brownish scales showed different microstructural types. This is inconsistent with the genetic model for the development of color patterns in Heliconius, which assumes a correlation between microstructure and pigmentation. Possibly, different genes are involved in alternative combinations between microstructure and pigmentation. Our third goal was to examine, by transmission electron microscopy, the ultrastructure of the fifth-instar larval wing discs. We showed that the formation of the epithelial bilayer of the wings, as well as the differentiation of the scale precursor cells occur already in the larval stage. Further, we reveal that the peripodial membrane plays an important functional role in the wing development, which challenges the traditional view of the peripodial epithelium as a simple surrounding membrane. The ultrastructural analysis of H. erato phyllis wings revealed important aspects involved in the developmental architecture of color patterns in Heliconius.

Texto completoKin recognition has been documented in various species of animals, plants, and bacteria. It is essential in altruistic interactions, in which an altruistic agent sacrifices some of its individual fitness to benefit the receiver, and indirectly increases its inclusive fitness, given that the receiver be a biological relative. Kin recognition is observed in Heliconius erato phyllis (Lepidoptera, Nymphalidae), whose newly hatched larvae can cannibalize eggs, and the cannibalism frequency of sibling eggs is significantly lower than that of non-related eggs. The objectives of this study were to elucidate the inheritance of kin recognition (non-cannibalism), and estimate its heritability; to evaluate the molecular nature of chorionic information, or chemical profile of the chorion, and of the newly hatched larvae profile; to associate molecular markers with behavioral phenotypes related to kin recognition; and, finally, to evaluate the effects of inbreeding, seeking to understand the possible effects of kin recognition on populations. It was observed that the recognition of relatedness, as revealed by non-cannibalism of sibling eggs, seems to have a heritable component. It is suggested that the inheritance of kin recognition is quantitative, with threshold manifestation, depending on many genes, as well as environmental factors. The chemical profile of newly hatched larvae and eggs differs quantitatively for various compounds, although qualitatively it is quite similar. In addition, there were statistically significant differences between families for various compounds, including both chorions and newly hatched larvae. Some compounds differ among families only with respect to the chorion samples, others only to larval samples, and other compounds differ for both materials. We have found some associations between the molecular markers AFLP and SSR and behavioral phenotypes related to kin recognition, in both experimental designs adopted. Moreover, inbreeding depression was observed only for some features related to life history. These results help to understand the kin recognition process and altruism in a species that is not social, and which also serve as a model for many evolutionary studies.

Texto completoKin recognition is important for the evolution of behaviors such as altruism and cooperation. Newly hatched caterpillars of Heliconius erato phyllis may be cannibals and recognize sibling eggs, preferentially cannibalizing non-kin when there is an option to cannibalize one or other. The present Dissertation comprises three related articles, specified below. The first approach was to try answering whether kin recognition observed in this species (demonstrated in an paper published in 2011 by the author), is compatible with the model of evolution by kin selection, which postulates that altruistic behavior is advantageous under given conditions. Costs and benefits of cannibalistic (selfish) and non-cannibalistic (altruist) behaviors were estimated. For this, a few parameters of ontogeny were used, such as egg weight and volume, duration of each instar and pupa, total days from hatching to adult emergence, growth rate, weight of the pupa, wings area, mortality of immatures and survival under starvation. The number of siblings of cannibals and non-cannibals that reach adulthood was also verified. The results showed that there were significant differences for egg volume and weight (noncannibal eggs are smaller than cannibal ones), and for duration of the first instar during the pupal stage, and total number of days from hatching to the adult stage (cannibals develop faster than non-cannibals).There was no difference in mortality between cannibals and non-cannibals, but cannibal survival without food was significantly higher. Thus, a few parameters of ontogeny indicate a few advantages of cannibal behavior. However, non-cannibals leave approximately double the number of siblings that reach adulthood, and siblings of cannibals and non-cannibals have the same development. Two modifications of Hamilton’s rule were made, from which it can be concluded that kin recognition observed in this species may have evolved by kin selection. Non-cannibals have the benefit of leaving more siblings, but suffer the cost of developing slightly slower, although these costs are limited to the immature stages. The second approach of this study, also a consequence of the 2011 work, was to detect where the recognition signal of the egg is, if in the chorion and/or in the embryo. First, cannibalism tests were 10 performed among half-siblings with the same father (it was not possible to produce half-siblings with the same mother, because in Heliconius erato phyllis, the female is monandric). The frequency of cannibalism was compared to the previous, aforementioned work, where it was 53% for sibling eggs and 83% for non-kin. The total frequency of cannibalism observed in this experiment (83.7%) is not different from that expected for non-kin, but different from the frequency of cannibalism expected for siblings, suggesting that half-sibling caterpillars do not recognize the remaining eggs as kin. This result in itself supports the idea that information about kinship is in the chorion of the egg. Cannibalism tests were also performed among caterpillars to verify whether the information about kinship could be in the cuticle that covers them, or in other structures. In cannibalism tests among first instar caterpillars that are siblings and non-kin, the frequency of cannibalism was not significantly different, thus, in this first test there was no evidence that the source of recognition was in the caterpillar. On the other hand, in tests among caterpillars from different instars, different behaviors could be categorized, and they were called indifference, flight, hostility, attack and cannibalism. There was also no statistically significant difference between sibling and non-sibling caterpillars, for the behavior categories analyzed. These results suggest that the signal evaluated for kin recognition is in the chorion of the egg, not in the caterpillar. The third approach of this study was to make inferences about the mode of inheritance of kin recognition (and cannibalism) in this species, by crosses, between sibling (r = 0.5) and non-kin (r = 0) cannibals, and between sibling and non-kin noncannibals. The offspring of these crosses was analyzed regarding cannibal and non-cannibal behavior. The ontogeny of cannibal and non-cannibal caterpillars resulting from the crosses, as well as of the remaining eggs, was followed to find whether there were differences in the development among individuals with different coefficients of inbreeding. The variables analyzed were egg weight and volume, duration of instars and pupa, total time from hatching to adulthood, growth rate, weight of pupa, area of wings and immature mortality. Independently of the parental behavior, for F = 0.25 there was a high frequency of non-cannibals (> 70%). On the other hand, for F = 0, there was a high frequency of cannibal caterpillars (> 50%). There were statistically significant differences among the non11 inbred and the inbred group for weight of the pupa and wing area (inbred smaller than non-inbred), and for mortality of the immatures (greater for inbred). The results suggest that kin recognition has a strong genetic component, while cannibalism appears to be due mainly to the absence or to few genes for recognition, and may have suffered major environmental influence. On the other hand, inbreeding produced effects, in the sense of expressing inbreeding depression. In this sense, although the present study used different variables, it confirms the deleterious effects of inbreeding, already published in a previous article on the same species.

Texto completoThis study investigates the wing coloration of two mimetic butterflies – Heliconius erato phyllis and H. besckei – as sexual signals. To know if two elements of the color pattern have function as mate recognition signals in the first species, behavioral experiments were done with female models. Both the red patch and the yellow bar were proved to be important to attract the males and release the courtship beginning. If the same signals involved in the mimicry are used in the sexual context, the possibility of a conflict of functions and reproductive interference between these species is reinforced. To verify whether there was some difference in the nature of the coloration between the two species, four wing regions were analyzed by spectrophotometry. The main difference was a marked peak of ultraviolet in H. erato almost nonexistent in H. besckei; a possible mechanism of specific discrimination witch would mitigate the costs of multifunctionality. The third approach of the study attempted to verify if there was some difference in the size of the coloration elements between the sexes of each species. We found that three of these elements are bigger in the males in both of them, but the one witch doesn’t have difference is not the same. We also observed that the elements of the dorsal face have its size strongly correlated with the ventral face ones. These variation patterns can be result of an epigamic sexual selection process and of evolutionary constraints related to other functions (defense and thermoregulation) or to development. The results of this study are discussed in the ecological-evolutionary context of the species in question, particularly with regard to the reinforcement of reproductive isolation and to the selective pressures that act on its coloration pattern.

Texto completoThe buttefly Heliconius erato phyllis is part of the group of Neotropical butterflies which are unpalatable and aposematic. This species has an asynchrony in sexual maturity between males and females. While females are already able to copulate after emerging, males have no ability to copulate before 6 to 7 days. The objective of this study was to investigate the causes of this asynchrony in sexual maturity between males and females using a physiological approach. We analyzed, by spectrophotometry methods, the metabolic variables glycogen, total lipids, triglycerides, total proteins, uric acid, lactate, lipo peroxidation and enzymatic activity of catalase and glutathione s-transferase in both sexes during metamorphosis and adult life before and after copulation. During metamorphosis glycogen appears to be the main substrate used in the development. Antioxidant enzymes remained higher in pupae than in adults indicating that they play an important role during metamorphosis. We found sexual differences, especially in adults, on the mobilization of energy resources. Males maintain lipid levels higher than in females during adulthood and glycogen in the early days. These results suggest that perhaps the sexual asynchrony H. erato phyllis is a matter of energetic capacity for males.

Resumo: Insetos fitófagos e suas plantas hospedeiras são um modelo valioso no estudo da influência do ambiente sobre o fenótipo, uma vez que estas são a única fonte de alimento e modulam a interação do herbívoro com outras espécies. Dado esse papel preponderante, espera-se que a planta hospedeira exerça influência em diversas características dos herbívoros, das mais diretamente relacionadas ao desempenho a diferenças sutis na morfologia. Além disso, deve haver relação inversa entre o desempenho e a magnitude da assimetria flutuante dos indivíduos criados em cada uma das hospedeiras. Para testar essas expectativas, estudamos o tamanho e a forma das asas, e sua assimetria, na borboleta Heliconius erato phyllis. Por meio das ferramentas da morfometria geométrica, testamos se havia variação em forma e tamanho entre indivíduos criados em diferentes hospedeiras e testamos também se havia assimetria direcional e flutuante. Detectamos uma variação marcada na forma das asas entre indivíduos que consumiram diferentes hospedeiras, uma assimetria direcional muito consistente, além de resultados pouco consistentes para a assimetria flutuante. Os resultados observados reforçam o papel da plasticidade fenotípica e das plantas hospedeiras na variação morfológica de insetos fitófagos, além de contribuírem com as atuais críticas à assimetriaflutuante como indicadora de desempenho.
Abstract: Phytophagous insects and its host plants are a valuable model to study how the environment can influence an organism's phenotype, as plants are the only food source and mediate the herbivore's interaction with other species. It is expected that the host exerts influence on diverse herbivore traits, from those directly related to performance to subtle differences in morphology. Além disso, deve haver relação inversa entre o desempenho e a magnitude da assimetria flutuante dos indivíduos criados em cada uma das hospedeiras. Besides, an inverse relationship between performance and fluctuating asymmetry is expected for individuals reared on different hosts. To test these expectations, we investigate variation in wing size, shape and asymmetry in the butterfly Heliconius erato phyllis. By using geometric morphometrics tools, we tested size and shape variation among hosts and also tested fluctuating and directional asymmetry in shape and size. We detected a strong wing shape variation among individuals reared on different host species, a very consistent directional asymmetry and inconsistent results for fluctuating asymmetry. The observed results reinforce the role of phenotypic plasticity and of the host-plants in the morphological variation of phytophagous insects, besides contributing to the current criticism raised against fluctuating asymmetry as an index of performance.

Texto completoThis thesis, through four manuscripts, covers various aspects on the phenotypic modulation in the pupal color of the in Heliconius erato phyllis. The first manuscript evaluate by heritability (h2) estimative two methods to measure the degree of melanization of pupal exuviae. The first of them, the qualitative method, considers four scores, ranging from 2 to 5, in an ascending order of melanization. The second method, quantitative, uses the optical density. After the capture, the images were analyzed by software from which were obtained values for the degree of melanization of each exuviae. From the values obtained for each methodology the h2 were estimated by the methods of linear regression and analysis of variance, with n ranging between 7 and 18 broods. Estimates of the h2 resulted in similar values for both methods of pupal categorization. Thus it is concluded that the qualitative methodology, for its usefulness, it is the most suitable for the task. From the low values of h2, we have two hypotheses. The first considers the sample size and the second the allocation priority resource. The second manuscript evaluates the influence of photoperiod on the pupal colour of H. erato Phyllis. Three broods had their eggs distributed between five photoperiods: 11L:13E, 12L:12E, 14L:10E, 9L:15E and 24L:00E. The first three represent photoperiod to Porto Alegre (RS-Brazil). The last indicated photoperiod is used as standard treatment by our group and was considered a control. The results found through the ANOVA twofactors to indicate a difference between the broods (p = 0,069) and do not indicate the difference between treatments. A second analysis was done by ANOVA one-factor considering only the pupal colour as a dependent on photoperiod. The results show a dependency among the factors (p = 0,047). A third analysis was performed to determine if the difference observed was due to the treatments or because of the genetic factors. To do this, a comparison at the treatment 24L:00E between the three broods with a set of 22 broods, reared under the same photoperiod, was performed. The result points to a genetic difference, concluding that the pupal colour of the in H. erato phyllis is not affected by photoperiod. The adaptation of pupas in field is the subject of the third manuscript. Two locations were used as the study area: Estação de Fitotecnia de Águas Belas (ABE) and Instituto de Pesquisas Hidráulicas (IPH). One hundred pupas were placed in each locality; 50 next to the ground and 50 above one meter. Each level of height were made by 25 pairs (25 cryptic and 25 non-cryptic). Among the 50 pupas of each level 25 pupae were light and 25 were dark. The results indicate dependence between survival and the level of when the pupas were placed. The camouflage and the colour not shown to be significant to the survival of the pupa in the field. Pupae placed near the ground have a chance between 8 and 13 times larger to be preyed than pupae over 1.0 meter tall. These results were linked to the type of predator observed in the field: ants. Two species and one genus of ants were observed preying pupae. Thus it is concluded that for pupae close to the ground, the camouflage provided by the colour is not adaptive, as the main predators not depend on the vision. The last article deals with the description of the first case of methylation in a butterfly: H. erato phyllis. Previous studies have shown that the estimates of heritability for the pupal colour in this species, determined by the method of linear regression, had different values when were considered male and their broods and female and their broods. One possible cause for this discrepancy could be due to the occurrence of DNA methylation and the possible silencing of genes. Through technical of MSRE and random primers PCR bisulfite we investigate the presence of methylation in H. erato phyllis. The analysis, using DNA from different stages of development, showed that the technique of PCR bisulfite was particularly efficient to indicate the presence of DNA methylation in this species. This opens the possibility of future research directed to assess whether this phenomenon has connection with the determination of differential colour patterns of the H. erato phyllis pupae. Finally this thesis has three appendices. The first is a process of selection for extreme phenotypes for the colour of the pupa in H. erato phyllis. Preliminary results indicate that the procedure is successful, however slow, as the variance for the feature remained relatively high when the process was interrupted. The second appendix addresses the effect of nuclear polyhedrosis virus on the pupal colour of this species. The event came after the emergence of dark pupae in the selection process for light pupae, when this phenotype was not more expected. So were investigated the effect of the virus on the pupal colour and on the survival of caterpillars, 4 th and 5 th instars. The results indicate that the virus does not influence the pupal colour. Moreover, there is a direct relationship between survival and individuals not infected. The third appendices describes an unusual phenotype to H. erato phyllis, where the adults had not red and yellow pigments, leaving the imago with a pattern black and white instead of black and red.

Texto completoThe purpose of this study was to examine the life of Phyllis Young (b. 1925) and her contributions to string education. The researcher explored her ancestry, childhood, education, personal life, and career as a cellist and string pedagogue. The study is divided into a prologue, five chapters, and an epilogue, and ends with her retirement from the University of Texas String Project in 1993. Phyllis Young, a faculty member at the University of Texas at Austin from 1953- 2007, was Professor of Cello from 1974-2007 and the Parker C. Fielder Regents Professor in Music from 1991-2007. She authored two books, Playing the String Game (1978) and The String Play (1986), and served as national president of the American String Teachers Association. She received that organization's Distinguished Service Award (1984) and the Paul Rolland Lifetime Achievement Award (2002). In 2006, the American String Teachers Association established an award in her name, The Phyllis Young Outstanding Studio Teacher Award. For forty years (1953-1993) Young was associated with the University of Texas String Project, a teacher training program that continues to serve as a model for numerous string programs nation-wide. She was director of the project from 1965-93. Young has given lecture-demonstrations, master classes, and workshops for string teachers in thirtythree countries on six continents and in forty-four of the American states. Her success as a pedagogue is substantiated through her numerous students, many of whom occupy significant musical positions in universities and orchestras, and as leaders in the string education field. Phyllis Young is a dedicated, passionate teacher whose legacy rests not only on her professional accomplishments, but also on her influence on those who have been associated with her. The success of her students, her influence on other string teachers and programs, and her two books, all lasting testaments to her commitment to excellence, can be considered the most significant components of her legacy.

Texto completoAdults of Heliconius erato phyllis (Lepidoptera; Nymphalidae) use flowers of several angiosperms with different colors and shapes as food source. In the present study, it was determined the phenology of Lantana camara Linnaeus, Stachytarpheta cayennensis (Rich.) Vahl, Glandularia tenuisecta (Briq.) W. Small (Verbenaceae), Dicliptera tweediana Nees (Acantaceae), and Melothria cucumis Vell (Cucurbitaceae), as well as the distribution and the utilization of these floral resources by H. erato phyllis. The distribution of resources was evaluated by monthly estimating the number of flowers on these species and their utilization by H. erato phyllis adults, based upon the quantification of pollen grains present on their proboscides. The availability of pollen and nectar throughout the day, and the butterfly response to the utilization of floral resources was evaluated for L. camara and S. cayennensis, through direct observations of feeding adults. Under insectary conditions, preference for different concentrations of sucrose was also investigated. For these experiments, feeders containing sucrose at concentrations of 0, 5, 10, 20 e 40 % were offered to the insects. The ability to associate color and concentration of sucrose in the nectar was evaluated by choice experiments, utilizing feeders with colors previously known as preferred and non-preferred by the insect. Concentrations of sucrose utilized in this experiment were: 0, 10, 20, 40, and 80%. The tests were performed with five different combinations of colors and concentrations. The ability of this nymphalid to discern plant colors for oviposition was also investigated in the insectary. In the tests, artificial purple and green shoots, similar to natural branches of Passiflora suberosa Linnaeus, were offered for oviposition. Innate preference for flower colors was evaluated by offering to young butterflies feeders in the colors purple, lilac, green, yellow, orange, red, black, and white. The association between color and presence of food (nectar) was evaluated for individuals captured and tested in a period of six days. In the first three days, butterflies received sucrose at a concentration of 1M in the red feeders. After this period, in each experiment, food was transferred to the other colored feeders. L. camara flowered the whole year, and presented a high number of inflorescences during the winter. The other species (S. cayennensis, G. tenuisecta, M. cucumis, and D. tweediana) had flowers only during spring and summer. During the winter, M. cucumis presented a random distribution, while the other species were aggregated. Multiple regression analyses indicated that L. camara explains the distribution of H. erato phyllis except during the winter. The mean number of pollen grains of L. camara attached to the proboscides of the butterflies was significantly higher than the other angiosperms investigated in the present study.Flowers of L. camara had a higher amount of pollen and nectar available for the butterflies in comparison with S. cayennensis. S. cayennensis floral nectar presented a higher concentration of sucrose when compared to flowers of L. camara. H. erato phyllis utilized flowers of L. camara more frequently and for a longer period during the day. Butterflies preferred sucrose solutions at concentrations between 10 and 20% and associated color with the preferred concentration. H. erato phyllis preferentially laid a higher number of eggs on green shoots. It also demonstrated an innate feeding preference for a group of colors (red, yellow, and orange). This heliconian butterfly becomes conditioned to use the feeder with sucrose. Moreover, it also demonstrated the ability to condition this behavior by utilizing feeders of different colors. Therefore, L. camara is an important resource for the adults of H. erato phyllis, in spatial and temporal scales, since it is available for a long period of time, in a high amount and is of better quality in comparison with other plants. In addition, the butterflies have an innate preference for a group of colors that are in accordance with the pattern of colors presented by the flowers of L. camara, and are capable of relating the preferred pattern with the concentration of nectar and sucrose present in the flowers. Also, this butterfly is able to discern colors for diferent behavioral strategies: oviposition and feeding. These aspects probably contributed for an efficient exploitation of the flowers of L. camara by H. erato phyllis throughout their evolutionary history, and for the high plasticity in use of a variety of other flowers when in the absence of L. camara.

Texto completoThis paper presents the characterization of the White-phyllite and an evaluation of its application as filler in the production of plastic materials. Phyllite samples with origin in ore body located in the district of Itapeva, southwest area of Sao Paulo State, they were beneficiated, prepared in laboratory through granulometric separation and drying and applied in the production of reinforced thermoplastic (Plastisol) in laboratories of the Braskem S. A. located in São Paulo city. The accomplished tests indicated that the beneficiated phyllite checks to the material plastic produced desirable properties of mechanical resistance and finish. The use of the phyllite it was compared with the calcite in the production of the plastics materials in several composition and proportions, showing in some compositions strips better than obtained results them with the calcite, traditional filler used for those products. The obtained results allow to conclude that the phyllite, properly beneficiated, is similar to traditional industrial minerals and it can benefit the industry of plastics reinforced in the production, among others, of balls, doll heads, rubber rugs, flexible plastic tubes, panels of vehicles.

Texto completoTypical symptoms commonly induced by phytoplasmas were found in sesame plants grown in commercial fields. These symptoms were characterized by shoot proliferation, leaves of reduced size exhibiting light chlorosis, and green petals. Total DNA extracts were obtained from diseased plants and used as template in nested PCR, in order to detect phytoplasmas in the tissues of the hosts. Genomic fragments of 1.2 kb corresponding to the 16S rDNA region were amplified demonstrating the association of phytoplasmas and diseased plants. Using nested PCR with specific primers, a phytoplasma belonging to group 16SrI was identified in all symptomatic samples. Based on the sequencing of 16S rDNA and in silico digestion, the virtual RFLP analysis allowed identify the presence of a phytoplasma affiliated with the subgroup 16SrI-B. This analysis also revealed a second phytoplasma distinct of all representatives of the subgroups within the group 16SrI. Similarity coefficients values and analysis of putative restriction sites confirmed the results obtained from virtual RFLP analysis indicating that this phytoplasma was representative of a new subgroup. A phylogenetic tree generated by the 16S rDNA sequences belonging to diverse phytoplasmas evidenced that this new phytoplasma emerged from a distinct branch, within of the 16SrI group. The sesame phyllody was previously reported in various countries in association with phytoplasmas belonging to 16SrI, 16SrII, and 16SrVI groups. The present study revealed the association of the phyllody with a phytoplasma affiliated with 16SrI-B and a phytoplasma representative of a new subgroup here named 16SrI-X.

Texto completoThe plant-insect interaction is a dynamic system. Variation in plant morphological traits such as hardness and thickness of the leaves can influence preference and performance of herbivores, depending upon the species and age of the plant structure taking into. On the other hand, insects can respond to these barriers through physiological and behavioral mechanisms. Nine species of passion vine are used by Heliconius erato phyllis (Fabricius, 1775) in Rio Grande do Sul State. However, their larvae feed preferentially on Passiflora misera Humbold, Bonplant & Kunth, which provide greater performance, despite having a lower amount of nutrients when compared to other host plants (e.g. Passiflora suberosa Linnaeus). Thus, the performance related to consumption of a particular passion vine possibly relates not only to their nutritional value, but also to morphological and behavioral mechanisms involved on feeding by these butterfly larvae. In this study, we investigate whether the difficulty in accessing food, imposed by the hardness and thickness of host leaves when in association to structural limitations on the mandibles of H. erato phyllis larvae, lead in turn to changes in host plant use. We examined the plant hosts damages and also larval behavior of this herbivore on five cultivated passion vine: P. misera, P. suberosa, Passiflora caerulea Linnaeus, Passiflora edulis Sims and Passiflora alata Dryander. Young and old leaves of these passion vine species were characterized in terms of hardness and thickness for the blade and the midrib. The frequency of differences on damage caused to P. misera, P. suberosa, P. caerulea and P. edulis was evaluated in relation to leaf age throughout larval ontogeny. Vickers hardness index was quantified for mandibles dissected from larvae reared on P. misera and P. suberosa. Additionally, the time spent in different behaviors (resting, feeding, walking, tasting and vein cutting) was quantified for the five passion vine, while feeding on both young and old leaves. The data showed the existence of expressive variation in hardness and thickness according to leaf age for the passion vine species used by H. erato phyllis larvae. The type (cutting blade, scraping and vein cutting) and frequency of damages were influenced by the variation of such leaf parameters. Scraping occurred when first instar were reared on old leaves. There was an ontogenetic influence on mandibular hardness, which increases with larval age. However, there was no evidence that the host plant influences the hardness in these structures throughout ontogeny. Independently of the host tanken into account, larvae employed most of the time resting. In several cases, they devoted more time feeding in P. misera. In P. alata, they spent more time resting and less time feeding, having up to only two meals of short duration each, at every six hours. This discrepancy in time is probably due to the presence of deterrent chemicals present in this passion vine. In old leaves of P. suberosa and P. caerulea, first instar larvae spent more time moving, thus showing that the search for an suitable food site is extremely important for this stage of development. Thus, we demonstrate that leaf hardness is a limiting factor for the early larval instars in this heliconian butterfly.

Texto completoThis work analysed the genetic and the environmental influence on the pupal colouration in the butterfly Heliconius erato phyllis. A total of 25 offspring were used in the study, 17 from crosses made in insectary, and 8 from females brought from nature, already inseminated. Pupal colour followed a system of discrete scores, from 2 for the light pupae to 5 for the darkest ones. To test the effect of environmental alteration (actually only one environmental component, namely the caterpillar sensitivity to a light or to a dark environment), each offspring was subjected to three treatments: control, darkness and whiteness, with caterpillars being transferred to these treatments in the beginnings of their 5th instar. The control treatment consisted in rearing caterpillars in translucent pots, with the bottom covered with beige paper and at a temperature of 25o C + 1o C and with permanent illumination. The two other treatments differed from the previous one by having their pots covered internally with white or with black paper; the remaining procedures being similar. Caterpillars, growing individually, received daily abundant food. Pupae from the dark environment originated pupae that scored 5 or sometimes 4; for those in the white environment, there were no differences with the controls. The case can be viewed as an example of phenotypic modulation, in which the degree of melanization of the pupa is influenced by a dark environment. To get more details on the time the caterpillars were sensible to the darkening of environment, they were tested at different age of development. When they were subjected to the dark treatment at the prepupal stage, the score for the pupae did not differ statistically from those of the control treatment. However, when subjected to the dark environment at the 5th instar, the resulting pupae had scores statistically different from the control treatment. This indicates that the critical period for inducing melanization is shortly around the 5th instar. The genetic component was studied through crosses where the degree of relatedness were taken into account (inbreeding coefficients of the sibship being 0.0 for the unrelated, and 0.125, 0.25, and 0.375). Heritability estimates (h2) were done by the methods of regression and analysis of variance. Four offspring from the crosses were inbred and were discarded in the estimates of heritability. However, they showed a decreasing variance in the scores for pupal colour as the inbreeding coefficient increased, suggesting a genetic background for colour. Estimates of heritability were around 0.30 when the score of the offspring were regressed on the midparental value. When regressed on the male parent, h2 was larger, varying from 0.40 to 0.73 and was generally negative and very low when female parent was the regressor. Estimates by the analysis of variance resulted in the interval 0.48 - 0.55. One additional fact comes from the black treatment. Even when fifth instar larvae were subjected to a dark environment, with the resulting pupae being dark, the analysis of variance showed a significant difference among offspring, which suggests genetic differences among the offspring not totally inhibited by the dark treatment. Our results dealing with the genetic component of pupal melanization are compatible with a polygenic control.

Texto completoEnterococcus is present in the gastrointestinal (GI) tract of vertebrates and invertebrates, which can acquire these bacteria through mechanisms of horizontal and vertical transfer of microrganisms. Recent research has described the presence of Enterococcus in Lepidoptera, but studies with butterflies of the genus Heliconius are scarce. This study had as objective, from a bacterioteca of 178 Enterococcus sp. previously isolated from fecal samples of immature Heliconius erato phyllis detect the presence of resistance and virulence genes by PCR; phenotypically assess the virulence factors and the production of compounds with antimicrobial activity; and to evaluate the clonal profile of the strains by PFGE. Of the 178 enterococci, 55 were resistant to erythromycin and 11 resistant to norfloxacin and/or ciprofloxacin, however was not detected any gene related to these resistance phenotypes. The virulence factors were tested in 178 enterococci, and 63 isolated amplified for the esp gene, 12 for ace and 2 for gelE. The agg and cylA genes were not detected. In the phenotypic analyzes, both E. faecalis positive to gelE gene were also positive for the degradation of gelatinase, and 130 enterococci showed ability to hydrolyze red blood cells. To investigate the production of antagonistic substance, 26 enterococci were selected and of these, 15 showed activity against the indicator bacteria Listeria monocytogenes. Eighty-six isolates were selected to evaluate the clonal profile by PFGE, and it was possible to observe in the dendrogram that the origin of the enterococci in GIT of immatures was the herbivory and maternal origin. It is concluded that the enterococci from fecal samples of immature H. erato phyllis possess few mechanisms of virulence-related genes, common in the clinical area. It is possible that the antagonistic substance-producing enterococci could play an important role in the equilibrium of the microbial communities of the GIT of this insect, and there is vertical transmission of enterococci from females to their offspring to the specie H. erato phyllis.

Resumo: Espécies com distribuições continentais podem ocupar várias zonas climáticas e diferentes vegetações, e forças seletivas locais podem gerar diferenças entre populações. A borboleta Heliconius erato phyllis possui esse tipo de distribuição e o teste G revelou diferenças significativas nos padrões de coloração das asas anteriores entre machos de diferentes regiões, mas não entre fêmeas. Melanismo, seleção sexual, atividade hormonal e predação podem estar envolvidos. O número de raios vermelhos nas asas posteriores apresentou correlação positiva com o comprimento das asas anteriores (CAA), mas exceções sugerem que tamanho e temperatura atuem como ativadores de hormônios que elevam a concentração de pigmentos para a formação dos raios. ANOVA demonstrou médias do CAA diferentes entre as populações, e o teste de Tukey apontou os maiores indivíduos em 3 sítios costeiros. Uma análise de componentes principais apontou altas temperaturas, pluviosidade e estabilidade climática como fatores ligados ao grande CAA. Esses fatores possivelmente contribuem com o crescimento de hospedeiras e com o desempenho larval. Técnicas moleculares usando marcador microssatélite foram aplicadas nas populações, em três escalas geográficas e uma temporal. Os resultados mostram grande variabilidade genética e populações sem isolamento por distância em escala continental. A reprodução é panmítica e os indivíduos possuem alta capacidade de dispersão mesmo entre fragmentos urbanos. Na escala temporal ocorreram diferenças estruturais moderadas, provavelmente devido a gargalos. Estudos em populações fragmentadas e de ampla distribuição ajudam a entender os efeitos do isolamento sobre a estrutura genética dessas populações e propor planos de manejo e conservação.
Abstract: Species with continental distribution can take several climatic zones and different vegetations, and local selective forces can generate differences among populations. The Heliconius erato phyllis butterfly has this kind of distribution, and the ?G? test showed meaningful differences on forewing color-patterns among males from different regions, but not among females. Melanism, sexual selection, hormonal activity and predation may be involved. The number of red raylets on hindwing show positive correlation with forewing's length (CAA), but exceptions suggest that size and temperature as triggers hormones that raise the concentration of pigments in the formation of raylets. The ANOVA showed different average on CAA among populations and the Tukey's test showed greatest individuals on 3 coastline sites. A principal component analysis indicated high temperatures, rainfall and climatic stability as major factors responsible for the large CAA. These factors possibly contribute with the growth of host-plant and the larval performance. Molecular techniques using microsatellite marker were applied on populations under three geographic scales and one temporal scale. The results show has a great genetic variability and populations without isolation by distance on continental scale. The reproduction is panmitic and the individuals have high dispersal ability even among urban fragments. On the temporal scale occurred moderate structural differences; probably due to bottlenecks. Studies on widespread and fragmented populations, help to understand the effects of isolation over the genetic structure of populations, and propose management and conservation plans.

Texto completoThis thesis focuses on the sociocultural discourse as well as the militant activities championed by conservativewomen in the United States, through the specific example of Phyllis Schlafly (1924-2016) and her organization EagleForum. This conservative activist mobilized her peers by drawing from her personal experiences, especially in theRepublican Party, and from ideological principles crafted by the conservative movement. Her personal trajectory,between conformity to social norms and involvement in the political arena, is discussed in parallel with the rise ofconservatism and in the context of the 1960s-70s social protest. In the face of thriving social movements, and more particularly feminism, which advocated women’s liberation, conservative women also resorted to collective action in order to protect what they saw as the traditional family construct, characterized by a strict division of work by sex. In their vision, the man is meant to be the sole breadwinner, ensuring the economic viability of the home, while the woman is a homemaker, taking care of home and children. In 1972, conservative women opposed the Equal Rights Amendment (ERA), which aimed to secure equality between the sexesin the U.S. Constitution. Phyllis Schlafly founded STOP ERA that same year, and Eagle Forum in 1975, in order tospread the conservative message and provide conservative women, often homemakers, with an organization into whichthey could channel their activism. Phyllis Schlafly crafted a strongly antifeminist discourse that opposed the feminists’ intention to liberate women and reform the family, and she advocated for traditional sociocultural norms that she considered beneficial to women. Thanks to appropriate collective action frames, coupled with her ability to manipulate emotions, she was able to spread her ideas throughout the country, especially with the use of her newsletter The Phyllis Schlafly Report.In order to strengthen her organization and insure her legacy, Schlafly also devised collective practices such as emotionalsupport and the construction of memory, thus developing a unique militant culture. She also established herself as anabsolute leader, solely at the forefront of the conservative women’s movement

Texto completoThis work aims primarily at studying the impact of various factors, and particularly the eradication of rats, on Arthropod assemblages in a sample of islands. We monitored populations of invertebrates using mainly pitfall traps and leaf point counts. Island geographical location and type of substrate seem important, although no factor appears dominant, hence microfactors (at microhabitat level) might well have an unsuspected influence. On granitic islands, invertebrate abundance, richness and diversity decreased sharply after rat eradication, suggesting a likely indirect facilitation on the invertebrate populations by rodents, particularly for Auchenorrhyncha (Hemiptera) (P<0,001). On the coralline island studied, however, eradication resulted in a significant increase (p <0. 05) in the abundance of Spiders (P <0. 01), Coleoptera (P <0. 05) and Formicidae (P <0. 05). These opposite reactions are probably related to the structure of the disturbed ecosystems, particularly to the presence of insectivorous animals which may be limited by rats (birds, reptiles, large insects). Our second objective was to attempt a first conservation introduction of the rare endemic Seychelles leaf-insect Phyllium bioculatum (Phasmatodea: Phylliidae). There were difficulties during the captive breeding phase and the released leaf-insects, reintroduced with a semi-captive procedure, disappeared or were found killed by unknown predators. However, this experience, which was the first documented conservation introduction attempt in the Indian Ocean, can serve as a basis for future similar projects. Finally, we discovered two species of Cratopus (Curculionidae) new to science and thus contributed to the inventory of the local entomofauna

Resumo: Uma comunidade de Heliconiini foi estudada no Parque Ecológico do Morro do Voturuá, no município de São Vicente, SP. Cinco espécies de plantas potencialmente hospedeiras (passifloras) estão disponíveis para a borboleta He/iconius erato phyllis. A relação Heliconiini-Passiflora, sobretudo defesas químicas, somadas a fatores ecológicos, genéticos, comportamentais, sazonais e fenológicos parecem governar a preferência desta borboleta sobre suas hospedeiras. Observações de campo e testes em condições seminaturais compararam os padrões de uso (no campo) e preferência (em insetário) das fêmeas, podendo envolver. atração química. O desempenho larval sobre as passifloras, enfocou possíveis influências destas plantas sobre o desenvolvimento da larva. O uso das hospedeiras no campo parece estar correlacionado com suas respectivas disponibilidades de acordo com a estação do ano. Nos testes em cativeiro, ocorre uma tendência de generalização na escolha das plantas à medida que se aproxima a primavera e uma rápida recuperação da preferência por Passiflora capsularis durante os meses de verão e outono. Os testes de desempenho larval apontaram uma coerência entre a planta mais usada com um bom desempenho larval. Passiflora capsularis e P. edulis dividem os resultados de melhor desempenho apesar da segunda ser escassa no campo e pouco utilizada. Passiflora jileki, a mais abundante no campo, apresenta o segundo maior percentual de uso, provavelmente devido a sua grande disponibilidade, mas o desempenho das larvas sobre ela é inferior as duas primeiras. O balanço entre seus percentuais de emersão (baixas) e o número. de P. jileki parece compensar seu uso no campo. Passiflora a/ata apresentou-se tóxica para as larvas e poucas plantas foram usadas no campo e no cativeiro. Passiflora amethystina não foi usada por nenhuma fêmea tanto no campo como no cativeiro e, portanto não se apresentou como uma hospedeira potencial. Os períodos sazonais e a interação destes com as espécies de hospedeiras, tiveram grande influência sobre o desempenho larval
Abstract: A community of Heliconiini butterflies was studied in the Parque Ecológico do Morro do Voturuá, municipality of São Vicente, SP. Five species of host plant are potentially available for the butterfly Heliconius erato phyllis. The relation between Heliconiini and Passiflora, especially chemical defenses, combined with local ecological, genetic, behavioral, seasonal, and phenology factors, seem to control the preference of this butterfly for these hosts. Field observations and tests under semi-natural conditions compared the patterns of female host plant choice, use (in the field) and preference (in the insectary), which may also involve chemical attraction. The larval performance on the Passiflora species shows possible influence of different chemical compounds in these plants on larval development. The use of hosts in the field seems to be correlated with the availability of plants in each season. In tests in captivity, there was a tendency towards generalization in the choice of host-plants as spring arrived, with a rapid return to preference for P. capsularis during the summer and autumn months. The tests of larval performance show correlation of the most used plants with better larval performance. Passiflora capsularis together with P. edulis show the best performance, though the latter is scanty in the field and thus little used. A third host, P. jileki, the most plentiful in the field, shows the second largest use, probably due its great availability, but larval performance on this species is inferior that on the first two. The combination of the rates of emergence (Iow) and the large number of P. jileki seems to balance in the use of this plant. Passiflora alata proved toxical to the larval and few plants were used in the field or in captivity. Passiflora amethystina was not used by any female, in the field or in captivity, and thus was not a potential host. The season cycle and its interaction with host species had a great influence on larval performance

Resumo: No presente estudo foram avaliados os fatores que influenciama escolha de plantas hospedeiras de larvas pelas fêmeas de Heliconius erato phyllis e a evolução da hierarquia das preferências dessas fêmeas por essas plantas. A área do estudo é uma Área de Proteção Ambiental, constituída por uma floresta estacional semi-decídua situada na Serra do Japi, Jundiaí, São Paulo e preservada para proteção de um manancial de água potável. Os dados foram coletados de abril de 1988 a abril de 1990, ao longo de duas trilhas próximas à represa de captação de água do Departamento de Águas e Esgotos de Jundiaí. A área foi dividida em duas sub-áreas denominadas Área Principal e Área Comparativa. As espécies de Passiflora encontradas na área foram P. alata, P. amethystina, P. capsularis, E. edulis, P. miersii, P. organensis, P. sidaefoliae, e P. suberosa. As espécies utilizadas na Serra do Japi pelas fêmeas de Heliconius erato phyllis para oviposição foram P. capsularis, P. organensis, P. sidaefolia e P. suberosa. Nas espécies de plantas usadas pelas larvas, foram encontrados dois tipos de meristema apical, que puderam ser distinguidos morfologicamente. Um desses tipos, mais ativo (meristema "rápido"), cresceu mais rapidamente e apresentou maior biomassa de folhas novas. O outro tipo, menos ativo (meristema "lento"), cresceu mais devagar e apresentou menor biomassa de folhas novas.

Abstract: In the present study the factors that influence the larval host plants choice by Heliconius erato phyllis females were evaluated.The evolutionof the ranking of host plant preferences were also investigated.The study site is a seasonal montane semi-caducifolius forest, situated on the Serra do Japi, Jundiaí, São Paulo state, Brazil. Data were collected along two trails near a dam, from April 1988 to April 1990. The total study area was divided in two sub-areas, denoted as "Area Principal" and' "Area Comparativa" .

One, with fast growth, named as ¿rápido¿, has a greater biomass of young leaves. The other, with slow growth, named as ¿lento¿, presents a smaller biomass of young leaves.
