Abstract (sommario):

EXPLANATION OF THE MASTER LISTSThere are 28 master lists, grouped as convenient taxon groups and split in such a way as to make each list individually downloadable but form an integral part of the main article. Citations to these master lists should be as indicated for the main article. Each master list contains a table that is made up of eight columns and each row represents information on one rearing record. For each master list, the rearing records are ordered under family, subfamily and sometimes tribe headings (in some cases we offer a superfamily instead of a family name where we were uncertain of the family placement). The records are ordered by family, subfamily, species and then rearer name. Explanation of the information contained in each column is as follows:Ref. no. This column contains references to a unique rearing number that links the notes, photographs and reared specimens gathered during the course of the rearing. A blank field indicate that there was no reference number submitted.Lepidoptera species. This column contains the best identification that could be made of the Lepidoptera taxon at the time of publication given the resources available. The name of the taxon specialist who identified the species (if not an author) is given in brackets. A blank cell means that we were unable to identify the taxon with some certainty.Host species (Family). This columns contain the best identifications that could be made of the host species, on which the caterpillar was feeding, at the time of publication given the resources available. A blank cell means that we were unable to identify the plant species to that level with some certainty or that feeding by the caterpillar was not confirmed. In the majority of cases the host indicated is the host on which the life stage was collected in the wild and on which the caterpillar fed subsequently. In cases where the host was presented to the larva in captivity, this is indicated. Where relevant, the name of the determiner is given in brackets. The host family name is given at the end in brackets. The phrase “reared ab ovum” means that the pictured larva was reared from the egg, meaning that the entire life-history of the species (all larval instars) was recorded and documented. In most cases such larvae were reared from eggs laid by a female moth collected at a light but raised on a natural host-plant of the species (though not necessarily one occurring at the locality where the female was taken), in some cases such larvae were reared from eggs found laid on a host-plant in the wild, and in a few cases the larvae were reared on an unnatural (exotic) host-plant in captivity. Such imprecisions regarding host use are, however, also contained in records of field-collected larvae, as mature larvae sometimes feed on plants they will not take in the early instars but do switch to at a later stage, and many also naturally feed on exotic plants in the wild.Locality. This column contains a short standardised reference to the locality where the specimen used in the rearing was collected, be it any life stage or a female from which eggs were obtained. The locality field lists, in order, the locality description, followed by the closest town, province (where relevant) and then country.Date of collection (c), pupation (p), emergence (e). This column contains the dates as indicated, where available. Missing dates are indicated by a “?”.Rearer. This column contains the name(s) of the person(s) who conducted the rearing, who may or may not have been the person who collected the rearing material.Final instar larva. This column contains the photographs of the caterpillar of the species reared. In most cases they depict the final-instar larva and at the time it was still feeding, but in some cases they show the larva in the pre-pupation phase (usually on the ground) and in a few cases an earlier instar, where for some reason a photograph of the final instar was unavailable.Adult. This column contains photographs of the actual adult specimen reared from the caterpillar shown in the previous column. Photographs marked with * are not of the actual adult specimen which emerged from the imaged larva.

Abstract (sommario):

Noctuidae is known to have high species diversity, although the genomic diversity of Noctuidae species has yet to be studied extensively. Investigation of transposable elements (TEs) in this family can improve our understanding of the genomic diversity of Noctuidae. In this study, we annotated and characterized genome-wide TEs in ten noctuid species belonging to seven genera. With multiple annotation pipelines, we constructed a consensus sequence library containing 1038–2826 TE consensus. The genome content of TEs showed high variation in the ten Noctuidae genomes, ranging from 11.3% to 45.0%. The relatedness analysis indicated that the TE content, especially the content of LINEs and DNA transposons, is positively correlated with the genome size (r = 0.86, p-value = 0.001). We identified SINE/B2 as a lineage-specific subfamily in Trichoplusia ni, a species-specific expansion of the LTR/Gypsy subfamily in Spodoptera exigua, and a recent expansion of SINE/5S subfamily in Busseola fusca. We further revealed that of the four TE classes, only LINEs showed phylogenetic signals with high confidence. We also examined how the expansion of TEs contributed to the evolution of noctuid genomes. Moreover, we identified 56 horizontal transfer TE (HTT) events among the ten noctuid species and at least three HTT events between the nine Noctuidae species and 11 non-noctuid arthropods. One of the HTT events of a Gypsy transposon might have caused the recent expansion of the Gypsy subfamily in the S. exigua genome. By determining the TE content, dynamics, and HTT events in the Noctuidae genomes, our study emphasized that TE activities and HTT events substantially impacted the Noctuidae genome evolution.

Abstract (sommario):

AbstractTraps baited with two types of chemical feeding attractants yielded 97 species of macrolepidoptera at three areas in Alaska (Fairbanks, Delta Junction, and Palmer). These were 16 geometrid, 1 thyatirid, and 76 noctuid moth species and 4 species of nymphalid butterflies. Potential crop pests trapped included Apamea devastator (Brace) (glassy cutworm), Xestia c-nigrum L. (spotted cutworm), Xestia smithii (Snellen) (Smith's dart), Euxoa ochrogaster (Guenée) (redbacked cutworm), and Discestra trifolii (Hufnagel) (clover cutworm). The clover cutworm was captured early in the season (May into June), while Smith's dart, glassy cutworm, spotted cutworm, and redbacked cutworm were captured in traps in mid to late summer. Many more species and greater numbers of moths were captured in traps baited with acetic acid and 3-methyl-1-butanol than in traps baited with a multicomponent floral lure (phenylacetaldehyde, methyl salicylate, methyl-2-methoxy benzoate, and β-myrcene). However, most of the geometrid moths captured (12 of 16 species) were in floral lure traps, while one species of Hadeninae (Noctuidae) and both species of Plusiinae (Noctuidae) were trapped exclusively in floral lure traps. The one thyatirid, both Catocalinae noctuid species, and most Amphipyrinae, Cuculliinae, Hadeninae, and Noctuinae noctuid species were captured in traps baited with acetic acid and 3-methyl-1-butanol. In addition, large numbers of bumblebees were captured in traps baited with the floral lure, while large numbers of yellowjackets were captured in traps baited with acetic acid and 3-methyl-1-butanol.

Abstract (sommario):

Abstract Six trap designs were assessed for capturing noctuid moths in field trials in the United Kingdom and Argentina. The traps were baited with either a sex pheromone for Autographa gamma in the UK trials and Helicoverpa gelotopoeon (Dyar) (Lepidoptera: Noctuidae) in Argentina, or a floral odor blend. In the UK trials the Universal Trap and a funnel sleeve trap were compared; in Argentina the funnel sleeve trap, a homemade bucket trap, and (L.) (Lepidoptera: Noctuidae) three sticky traps: LepTrap, wing trap, and delta trap were compared. Comparisons were made between the traps and attractants and captures of noctuid moths and nontarget insects. Traps baited with the floral attractant caught a lower number but a wider range of noctuid species including Helicoverpa, Spodoptera, Rachiplusia, Dargida, Mythimna, Chrysodeixis, Agrotis, and Autographa spp., and nontarget insects. In the UK trials, the funnel sleeve trap caught significantly more A. gamma than the Universal Trap. The addition of an insecticide to the Universal Trap marginally increased trap catches. In the Argentinian trials, the homemade bucket and the sleeve traps outperformed all sticky traps in most situations regardless of crop environment and attractant type. The homemade bucket and the funnel sleeve traps are also considerably cheaper than the other trap designs. Of the sticky traps the LepTrap caught more noctuids than the wing and delta traps. The results suggest that the bucket trap and the sleeve trap have a much greater maximum capacity and possibly a greater retention efficiency for noctuid moths compared to the sticky traps.

Abstract (sommario):

Aprica Goldstein, gen. nov. is described to accommodate Xanthiapatula Druce, 1898. Recent discovery of its larva, which has been recorded eating foliage of species in six families of leptosporangiate ferns, suggest a possible subfamily assignment within the Eriopinae, but this cannot be substantiated based on adult morphology. This species has no obvious close relatives either among the core noctuid pteridivore genera currently recognized in the Eriopinae (e.g., Callopistria Hübner, [1821]), nor among genera more recently discovered to be fern-feeders but which remain incertae sedis with respect to subfamily (e.g., Leucosigma Druce, 1908, Lophomyra Schaus, 1911). The recorded foodplant profile is similar to that of another ambiguously placed Nearctic species Fagitanalittera (Guenée, 1852) (Noctuidae: Noctuinae: Xylenini, incertae sedis) with which it shares no obvious synapomorphies.

Abstract (sommario):

Foi realizada a revisão e analise filogenética do gênero Dargida Walker, 1856, um gênero americano composto por 56 espécies válidas, normalmente encontradas em locais com predominância de gramíneas. Algumas das espécies deste gênero são consideradas pragas de importância econômica. Estão distribuídas desde o Canadá ao Chile, ocorrendo do nível do mar até quase 4000 metros de altitude, porém nenhuma das espécies apresenta distribuição contínua pelo Continente. O desenvolvimento do trabalho foi realizado com base na revisão de coleções entomológicas nacionais e estrangeiras. Analisou-se mais de 5000 espécimes, foi atualizada a distribuição geográfica conhecida para o gênero assim como obtidos novos registros para grande parte das espécies. Foi construída uma matriz de caracteres morfológicos, analisados nos programas TNT e Mr. Bayes. As topologias finais mostram que Dargida é um gênero polifilético formado por um grupo sensu stricto que contem as espécies que serão consideradas como Dargida (aquelas com maior semelhança à espécie-tipo), e um grupo denominado sensu lato menos sensu stricto, formado pelas espécies cujas características morfológicas são diferentes às da espécie-tipo. Devido aos resultados da analise filogenética, mas, também a os dados obtidos na analise morfológica, na revisão do gênero Dargida Walker, 1856 foram incluídas somente as espécies do grupo sensu stricto, sendo que as restantes espécies deveram ser realocadas em outras unidades genéricas ou deveram ser criados novos gêneros nos quais estás deveram ser arroladas.
Was carry out a revision and phylogenetic analysis of the genus Dargida Walker, 1856, an American genus composed by 56 valid species, usually founded in places with grass plants dominace. Some species of genus are considered pests of economic importance. The group is distributed from Canada to Chile, occurring from sea level to almost 4000 meters of altitude, however, no species has a continuous distribution throughout Continent. To develop this work were revised national and foreign entomological collections. More than 5000 specimens were analyzed. Was update the geographical distribution of genus as well as new records were obtained for most species. Was constructed a matrix of morphological characters and analyzed in TNT and Mr. Bayes programs. The final topologies show that Dargida is a polyphyletic genus formed by a sensu stricto group that contains species that will be considered as Dargida (those with more similarity to the type-species), and a group denominated sensu lato minus sensu stricto, formed by species whose morphological characters are different from those of type-species. Due to the results of the phylogenetic analysis, but also to data obtained from morphological analysis, only species of sensu stricto group were included in the revision of genus, the remaining species should be relocated in other generic groups or should be created new genera in which list thouse species.

Abstract (sommario):

Sunflower production in South Africa has increased four fold since the 1970's. This study was done to elucidate the pest status of Heliothis armigera (Hiibner) on sunflower. Field studies were undertaken at Warmbaths, Brits and Delmas during the summer seasons of 1988/89 to 1990/91. The infestations at the latter two areas were negligible throughout the study period and their statistics have not been included in this thesis. Plant development and oviposition by natural H. armigera populations were found to be correlated as, regardless of planting date, oviposition started at six to seven weeks after planting; when the flowering stage began. A peak in egg numbers was reached by the tenth week with an average for the three seasons at two eggs per plant. The eggs were laid singly on the bracts and bases of the flower buds. A peak in larval numbers was reached at the thirteenth week after planting with the average for the three seasons of 0,4 larvae per plant. The preferred feeding sites were on, between and under the bracts from where the larvae burrow into the pithy tissue of the receptacle. Only six percent of the larvae were found feeding directly on the achenes. Eggs and larvae collected were reared to determine the degree of parasitism. Overall, 19% of the eggs were parasitised; 18% by Telenomus ullyetti Nixon (Scelionidae) and one percent by Trichogrammatoidea lutea (Trichogrammatidae). Larval parasitism at Warmbaths was 23% in 1988/89, 27% in 1989/90 and 34% in 1990/91. Of the parasitised larvae, 44% succumbed to Palexorista prob. laxa (Tachinidae). The remainder were unidentified Braconidae and Ichneumonidae. Predators, such as chrysopids, were observed during the study but their effect on egg and larvae numbers was not studied in detail. A polyhedral virus occurred late in the seasons and caused mortality of the larvae. The low numbers of H. armigera on sunflower, the slight damage to the crop and the reasonably high rate of parasitism, all seem to indicate that H. armigera is not an economica1ly important pest of sunflower and that additional control methods are not justified.

Testo completo

Abstract (sommario):

The presence and properties of proteases present in larval midgut extracts from Spodoptera littoralis was investigated. Trypsin and chymotrypsin activities were found mainly in the midgut lumen while leucine aminopeptidase and dipeptidyl aminopeptidase IV activities were found solely in the midgut tissue. Hydrolysis of carboxypeptidase substrates indicated carboxyesterase A activity only. The characteristics of trypsin, chymotrypsin and leucine aminopeptidase were determined with respect to a variety of factors including pH, temperature, substrate concentration, P(_1) amino acid specificity and molecular weight. Inhibition of the endopeptidases by a wide variety of protease inhibitors derived from chemical, microbial, plant and animal sources was also carried out. Endopeptidase activities were compared with proteases from Helicoverpa armigera and mammalian sources and the endopeptidase specificity discussed. In addition, a haemolymph phenoloxidase (PO) was characterised (pH, substrate concentration), purified and the effects of various zymogen activating and PO inhibitory substances determined. Finally, two parasites were studied. Firstly, the ultrastructure of stages in the life-cycle of a microsporidian parasite (Nosema sp.) from H. armigera and secondly, the morphological changes associated with a nuclear polyhedrosis virus (NPV) disease in S. littoralis, together with ultrastructural characterisation and comparison of restriction endonuclease patterns of the nucleic acids between NPVs from different sources.

Abstract (sommario):

Genetically modified (GM) cotton expressing Cry1Ac proteins was released in South Africa in 1997 for control of the bollworm complex on this crop. No reports of the failure of Bollgard® cotton to control these pests have yet been made. Throughout the world there are concerns about the development of resistance of target pests to Bt cotton due to the use of only one Bt gene. The aim of this study was to determine if Helicoverpa armigera (Lepidoptera: Noctuidae) and Diparopsis castanea (Lepidoptera: Noctuidae) developed resistance to Bt cotton in South Africa. To determine if H. armigera developed resistance, laboratory experiments were conducted to determine the levels of larval survival and development time when feeding on Bt and non–Bt cotton. Bollworm populations were collected on maize and cotton at different sites in South Africa and reared on Bt and non–Bt cotton under laboratory conditions. Results showed that some populations survived on Bt cotton and that a significant proportion of the individuals successfully completed their life cycles on Bt cotton. Surveys were also conducted amongst cotton farmers to determine the levels of compliance to the refuge strategy that has to be implemented by farmers as an insect resistance management (IRM) strategy to delay resistance development. The levels of compliance to refugia requirements were low and farmers generally only started planting refugia several years after they planted Bt cotton for the first time. The development of resistance of H. armigera to Bt cotton in South Africa can possibly be ascribed to non–compliance to the prescribed refuge requirements. No conclusions can be made on resistance of D. castanea to Bt cotton but the relatively long time to mortality of larvae could indicate development of tolerance to Cry1Ac proteins. The new generation Bollgard II® cotton, expressing both Cry1Ac and Cry2Ab2 proteins, has been released in South Africa during the 2010/11 growing season and field observations showed effective control of the bollworm complex at several sites in the country. Monitoring of refuge compliance levels as well as resistance development in the bollworm complex to Bollgard II® cotton is necessary to ensure the future success of GM cotton.

Os vírus de poliedrose nuclear são importantes agentes de controle microbiano de larvas de lepidópteros. No entanto, sua atividade pode ser comprometida durante a interação com suas plantas hospedeiras. Entender como ocorre a interação do vírus da lagarta Chrysodeixis includens, ChinNPV, com dois de seus hospedeiros, soja e algodão, pode auxiliar a expandir o uso de pesticidas biológicos amenizando suas limitações. A interação planta/vírus foi estudada a fim de verificar a influência da planta sobre o processo de infecção, alterando a forma e o momento em que as larvas se alimentam desses substratos. Os tratamentos foram: disco de folha, incorporação de folha (liofilizada e seca em estufa) em dieta, alimentação com substrato foliar antes da inoculação viral, persistência e exposição do vírus sobre a planta. As avaliações foram realizadas até o 10º ou 12º dias após a inoculação, quando foram determinados o peso e o estágio de desenvolvimento de cada sobrevivente. Os dados de mortalidade foram submetidos à análise de sobrevivência com riscos competitivos e os demais dados à ANOVA. Alterações histopatológicas no intestino médio das lagartas alimentadas com folhas de soja e algodão e inoculadas com o ChinNPV foram analisadas por microscopia de luz. A fixação das partículas virais foi avaliada através da extração da cera epicuticular com cinco solventes, seguida de aplicação, lavagem e contagem do vírus remanescentes. Fixação, morfologia e persistência dos poliedros sobre folhas de soja e algodão, em ambiente controlado e campo, foram avaliadas por MEV em diferentes períodos. A mortalidade das lagartas foi comprometida pelo algodão em quase todos os bioensaios realizados. A inoculação do NPV sobre discos de folha de soja resultou em mortalidades semelhantes à dieta. No entanto, quando tecidos liofilizados foram incorporados à dieta, os folíolos de soja reduziram a mortalidade de C. includens por NPV, com mortalidade análoga à provocada pelo algodão e, quando secos em estufa, a mortalidade larval foi intermediária, entre o apresentado pela dieta artificial e as folhas de algodão. Quando o vírus foi exposto na superfície da soja e posteriormente recuperado, o tempo de contato com a folha (72h) reduziu a atividade do vírus, o mesmo não foi válido para o algodão. A análise histopatológica mostrou desestruturação das células epiteliais no tratamento de alimentação prévia com folha, entretanto este fenômeno não alterou a mortalidade das lagartas. Enquanto em campo, a distribuição dos poliedros foi uniforme no filoplano das duas culturas, no laboratório, os poliedros formaram agregados sobre a superfície da soja. Já quando a cera epicuticular foi removida, a interação da folha com o vírus foi afetada. A atividade do ChinNPV foi comprometida tanto por folhas de soja quanto algodão, sendo que a persistência do vírus começa a reduzir após o terceiro dia de contato com o filoplano. Foi possível observar que a inativação do vírus somente ocorre quando folha de algodão e vírus são fornecidos em conjunto, enquanto na soja, o tempo de contato do vírus com a folha parece influenciar reduzindo a mortalidade das lagartas. Assim, seria interessante estudar formulações e doses para compensar a perda de atividade viral provocada pelos tecidos foliares.
Nucleopolyhedrovirus are important microbial control agents of lepidopteran larvae. However, their activity may be compromised during interaction with their host plants. Understanding the interaction process of the caterpillar virus Chrysodeixis includens, ChinNPV, with two of its hosts, soybean and cotton, may help to expand the use of biological pesticides by alleviating their limitations. The plant/virus interaction was studied in order to verify the influence of the plant on the infection process, changing the form and the moment in which the larvae feed on these substrates. The treatments were: leaf disc, incorporation of leaf (lyophilized and oven-dried) in diet, feeding with leaf substrate before viral inoculation, persistence, and virus exposure on the plant. Evaluations were carried out until the 10th or 12th days after inoculation, when the weight and stage of development of each survivor were determined. Mortality data were submitted to survival analysis with competitive risks and the other data to ANOVA. Histopathological changes in the midgut of caterpillars fed with soybean and cotton leaves and inoculated with ChinNPV were analyzed by light microscopy. Fixation of the virus particles was evaluated by extracting the epicuticular wax with five solvents followed by the application, washing and counting of the remaining virus. Fixation, morphology and persistence of the polyhedra on soybean and cotton leaves, under controlled environment and field, were evaluated by SEM on different periods. The mortality of caterpillars was compromised by cotton in almost all bioassays performed. NPV inoculation on soybean leaf discs resulted in diet-like mortalities. However, when lyophilized tissues were incorporated into the diet, soybean leaflets reduced the mortality of C. includens by NPV, with mortality similar to that caused by cotton, and when drying in oven, the larval mortality was intermediate between that presented by artificial diet and cotton leaves. When the virus was exposed on the soybean surface and later recovered, the time of contact with the leaf (72h) reduced the activity of the virus; the same was not true for cotton. The histopathological analysis showed disruption of epithelial cells in treatments of previous leaf feeding; however, this phenomenon did not change the mortality of caterpillars. While in the field, the polyhedra distribution was uniform on the phylloplane of the two cultures, in the laboratory, the polyhedra formed aggregates on the surface of the soybean. Already when the epicuticular wax was removed, the interaction of the leaf with the virus was affected. The activity of ChinNPV was compromised by both soybean and cotton leaves, and the persistence of the virus begins to decrease after the third day of contact with the phylloplane. It was possible to observe that the inactivation of the virus only occurs when cotton leaf and virus are supplied together, while in soybean, the time of contact of the virus with the leaf seems to influence, reducing the mortality of the caterpillars. Thus, it would be interesting to study formulations and doses to compensate for the loss of viral activity caused by foliar tissues.

Abstract (sommario):

Los nucleopoliedrovirus (NPV) son patógenos de insectos empleados a nivel mundial para el control de diferentes plagas (Barreto et al. 2005). Con un aislamiento nativo de este virus se desarrolló un bioplaguicida para el control del gusano cogollero Spodoptera frugiperda (J.E Smith) (Lepidoptera: Noctuidae), la plaga más importante del cultivo de maíz (Barón y Angulo 2003). Los NPVs son patógenos obligados y su producción masiva se realiza infectando larvas del insecto hospedero, las cuales son alimentadas con una dieta semisintética que aumenta considerablemente los costos de producción del bioplaguicida (Elvira et al., 2010). Con miras a hacer más competitivo el proceso de manufactura del insecticida viral, el presente trabajo pretendió seleccionar una dieta modificada a partir de la dieta estándar actualmente empleada, reduciendo sus costos de elaboración y determinando su efecto sobre el desarrollo larval y la productividad viral.

Abstract (sommario):

The species Chloridea virescens and Helicoverpa zea (Lepidoptera: Noctuidae) are declared agricultural pests with a high economic impact worldwide (Angulo et al. 2008). They are widely distributed on the American continent, and agrochemical are the most common method to control, which can cause environmental, social, economic and public impacts. A strain of Metarhizium rileyi Nm017 [AGROSAVIA - Orinoquia area (Col.)], demonstrated an e cacy of 75.8% on C. virescens, and 92.5% on H. zea on laboratory conditions. Mass production and virulence of Metarhizium sp. are susceptible to stress conditions such as temperature, UVB radiation and pH, a ecting conidial vigor, germination, and sporulation (Rangel et al. 2008, Oliveira et al. 2016). Likewise, the culture medium can a ect the infection processes measured through hydrophobicity and enzymatic activities (Ortiz 2013). The identi cation of these parameters allows selecting the most favorable conditions for its production and the challenges that must be assumed in downstream processes.

Se establecieron límites de aceptación de estos y se estandarizó una metodología alterna para evaluar la actividad biológica utilizando como insecto modelo Chloridea (Heliothis) virescens (Lepidoptera: Noctuidae), mediante una prueba r&R. Los resultados obtenidos para cada parámetro permiten ser utilizados como referente en el control de calidad rutinario de estos micoinsecticidas. Antecedentes: Se seleccionó el aislamiento Bv060 de Beauveria bassiana por ocasionar 87,4 % de e cacia sobre adultos de C. tingomariana en laboratorio. Debido a su potencial, se desarrolló un granulado dispersable (WG) y un concentrado emulsionable (EC) a base de este hongo, pero es necesario determinar los criterios de calidad de estos micoinsecticidas. Objetivos: 1. Caracterizar tres lotes y establecer los límites de aceptación para los parámetros microbiológicos, sicoquímicos y biológicos de las dos formulaciones. 2. Estandarizar una metodología alternativa para la evaluación de la actividad biocontroladora de los formulados, utilizando como insecto modelo C. virescens debido a la dificultad en el establecimiento de la cría y la disposición constante de adultos de C. tingomariana. Hipótesis: 1. Los coeficientes de variación (CV) son inferiores al 10 %, indicando repetibilidad entre lotes, permitiendo el establecimiento de límites de aceptación. 2. Chloridea virescens se puede utilizar como insecto modelo para determinar la actividad biocontroladora de preformulados a base del aislamiento Bv060 de B. bassiana.
