Повний текст джерелаCotesia flavipes (Cameron) (Hym., Braconidae), as other koinobionts, is capable of regulating the host development to produce an suitable host environment to sustain and promote its own larval development at the host expenses. Female-derived substances from the reproductive tract (ovarian proteins, venom, polydnavirus) are injected into the host, affecting the host immune response and other physiological processes aiming to regulate the host hormone levels, nutrition and behavior. Our goal was to evaluate the role of these substances on Diatraea saccharalis (F.) (Lepidoptera: Crambidae) growth and development, and how the parasitism affects the host immune response. All female-derived substances were collected after parasitoid dissection by collecting the venom reservoir or the ovaries (ovarian proteins and polydnavirus). Dissections were carried out in ice-cold buffer, collected tissues were processed accordingly and the desired substances injected immediately after collection. Venom and ovarian proteins+polydnavirus (PDV) were injected jointly and separated in 0-12 hold 6th instars of D. saccharalis. The effect of these substances on host development and growth was evaluated by measuring the host weight gain, larval and pupal survivorship and developmental time. The effects of the parasitism on the host immune response was evaluated either at the cellular level, by measuring the total hemocyte count and the encapsulation capacity, and at the biochemical level, by measuring the prophenoloxidase activity and nitric oxide levels at different stages of parasitoid development (0, 1, 3, 5, 7 and 9 days after parasitism). Parasitoid ovarian proteins and PDV alone or co-injected with the venom arrested the host larval development, while the venom by itself only affected the host metamorphosis process. The host immune response was also affected by C. flavipes at a time-dependent manner. The total hemocyte count dropped at day 3 of parasitism, while the host encapsulation capacity was reduced during parasitoid development. The host prophenoloxidase activity was also affected mainly towards the end of parasitoid larval development, while the nitric oxide at the first 24 h after parasitism.

Microcharops anticarsiae é um eficiente parasitoide da lagarta-dasoja Anticarsia gemmatalis que, também, parasita lagartas de outras espécies como Chrysodeixis includens e Spodoptera eridania. O objetivo do trabalho foi (1) determinar o ínstar larval de A. gemmatalis preferencialmente parasitado por M. anticarsiae a partir de lagartas coletadas em campo, (2) determinar o efeito de criações sucessivas de M. anticarsiae nos parâmetros biológicos do parasitoide e (3) determinar o efeito da soja transgênica sobre a longevidade de adultos do parasitoide. Os experimentos foram conduzidos nos anos agrícolas de 2014/15 e 2015/16 na FCAV/UNESP, Jaboticabal, SP, Brasil. Para a coleta das lagartas em campo, foram semeadas duas áreas de soja transgênica, uma tolerante ao herbicida glifosato e a outra resistente a insetos. Os resultados indicam que (1) M. anticarsiae preferiu parasitar lagartas de A. gemmatalis de primeiro e segundo ínstar em soja tolerante ao glifosato em campo, (2) não houve diferenças nos parâmetros biológicos de M. anticarsiae criado durante três gerações sucessivas em laboratório e (3) a longevidade total de M. anticarsiae e a longevidade de fêmeas foi mais longa em soja tolerante ao glifosato e a longevidade dos machos foi mais curta em ambas as sojas, tolerante ao glifosato e resistente a insetos. Finalmente, conclui-se que M. anticarsiae parasita lagartas de A. gemmatalis de primeiro e segundo ínstar em campo, que os parâmetros biológicos de M. anticarsiae não são afetados quando criados durante três gerações em laboratório e que a soja resistente a insetos afeta negativamente a longevidade dos machos de M. anticarsiae.
Microcharops anticarsiae is an efficient parasitoid of Anticarsiagemmatalis and also parasitizes larvae of other species such as Chrysodeixis includens and Spodoptera eridania. This work aimed to (1) determine the larval ínstar of A. gemmatalis preferentially parasitized by M. anticarsiae from larvae collected in the field, (2) determine the effect of successive laboratory rearings of M. anticarsiae in the biological parameters of the parasitoid, and (3) determine the effect of transgenic soybean in the longevity of adults of the parasitoid. the experiments were carried out in the seasons 2014/2015 and 2015/2016 in the FCAV/UNESP, Jaboticabal, SP, Brasil. Two areas were sown with transgenic soybean, the first one tolerant to glyphosate and the second one resistant to insects. The results indicate that (1) M. anticarsiae preferred to parasitize A. gemmatalis larvae on the first and second larval ínstar in soybean tolerant to glyphosate in the field, (2) there were not differences in the biological parameters of M. anticarsiae reared during three successive laboratory rearings, and (3) the longevity total of M. anticarsiae and longevity of females was longer in soybean tolerant to glyphosate and the longevity of males was shorter in soybean tolerant to glyphosate and resistant to insects. Finally, we conclude that M. anticarsiae parasitize first and second ínstar larvae of A. gemmatalis in the field, the biological parameters of M. anticarsiae are not affected when reared during three generations in the laboratory, and the soybean resistant to insects affects negatively the longevity of males M. anticarsiae.

Повний текст джерелаKairomones are semiochemicals involved in interspecific interactions of insects that benefit the receiver to the detriment of the emitter. One of these interactions is host searching by parasitoids which detect these compounds as a strategy to locate their hosts. In the case of the larval ectoparasitoid, Habrobracon hebetor Say (Hymenoptera: Braconidae), the \'frass\' of Anagasta kuehniella Zeller (Lepidoptera: Pyralidae) releases a kairomone that attracts females parasitoids. Considering that A. kuehniella has been used for egg production in order to keep natural enemy rearing, this kairomone is undesirable, because it may lead to high H. hebetor infestation and causes important losses during the rearing process. One of the attempts to control these infestations could be the use semiochemical-baited traps. However, as the kairomone is still unidentified, the aim of this work was to isolate it - the first step for its identification. The kairomone was extracted by solvent washing and aeration of A. kuehniella \'frass\'. Then the extracts were tested in a four-way olfactometer with female parasitoids, registering the time taken in each treatment. The active washing extract was fractionated in five fractions in a silica column, and its attractivity was evaluated to proceed to isolation. The extracts and fractions were then analysed by gas chromatography with flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC-MS), in order to locate exclusive compounds in active samples. Furthermore, the fractions from the washed extract were aerated to extract their volatile compounds that were also analysed by GC-MS. The kairomone was isolated in the 75% ether fraction, indicating that it is a polar compound. Comparing the chromatograms, only one peak on the HP-5ms column was selected as belonging to the kairomone. On the Rtx-1ms column, the peak bifurcated, indicating that at least one of the compounds is part of the kairomone. The methodological combinations of this work provided the isolation of the kairomone present in A. kuehniella \'frass\' and the selection of at least one compound that comprises the semiochemical that attracts H. hebetor parasitoid, resulting in the first source of information about its chemical structure for its future identification.

O algodoeiro geneticamente modificado para a produção de toxinas da bactéria Bacillus thuringiensis (=Bt) tem como principal objetivo oferecer a planta resistência contra larvas de lepidópteros. O cultivo do algodoeiro Bt no Semiárido pode estar submetido a diferentes condições edafoclimáticas, principalmente, ao estresse hídrico. Assim, este estudo investigou a produção da toxina Cry1Ac em algodoeiro Bt variedades Acala 90B e NuOpal com plantas submetidas ou não ao estresse hídrico e a preferência para oviposição e alimentação de Alabama Argillacea (Hübner) confinadas sobre essas plantas. Plantas de algodão foram cultivadas em microparcelas em casa telada e submetidas ao controle de irrigação para a obtenção de plantas com estresse hídrico. A produção de Cry1Ac foi maior em folhas de plantas Bt de ambas as variedades submetidas ao estresse hídrico, e similar nas demais partes como brácteas, pétalas e casca de maçãs. Mariposas de A. argillacea não apresentaram preferência para ovipositar entre plantas de algodão Bt e não-Bt. Da mesma forma, as larvas com três ou 10 dias de idade não apresentaram preferência para alimentar em folhas de variedades não-Bt comparadas a Bt, em testes com chance de escolha. Por outro lado, mariposas de A. argillacea preferiram ovipositar em plantas sem estresse hídrico e larvas não completaram o desenvolvimento em plantas não-Bt sob estresse hídrico de ambas as variedades. Estes resultados mostram que tanto mariposas quanto as larvas de A. argillacea não foram capazes de reconhecer plantas de algodão Bt para ovipositar e alimentar, respectivamente. Também, que plantas de algodoeiro submetidas ao estresse hídrico apresentam diferenças quanto à quantidade da toxina Cry1Ac nas folhas, interferiram com a preferência de oviposição de A. argillacea, bem como com o seu desenvolvimento larval.

Повний текст джерелаSize (S), heterogeneity (H) and connectivity (C) define plant structure. The development of the model of parasitism was based on laboratory experiments using three dimensional artificial plants of different combinations of S, H and C. The model was then validated with experiments, within greenhouse, using natural cruciferous plants of different structures. Significant regressions of observed values of parasitism as a function of those predicted by the model were obtained.
The effect of plant structure on two species of Trichogramma was studied by using three species of Lepidoptera and three structurally different but closely related crucifers. Also the distribution pattern of parasitized eggs according to leaf side and plant height was characterized. A repeated measure ANOVA in time where plant ages defined the repeated measures showed that all three main effects (plant, host, parasitoid) had significant effect on parasitism and only the parasitoid x plant structure interaction was significant. Mean percent of parasitism was higher on cabbage, intermediate on broccoli and lower on Brussels sprouts whereas cabbage appeared to be intermediate in plant structure, broccoli appeared to be the most simple and Brussels sprouts the most complex plant structure. On simple plant structure, both wasp species performed well on the three varieties of plant but T. evanescens outperformed T. pretiosum more often on the various plant structures. A doubly repeated measures ANOVA in space revealed significant effects of leaf side and plant height on parasitism, being greatest under leaf surface and at the base of the plant. The interaction between those two variables was not significant.
The effect of plant structure on searching behavior of T. evanescens was determined by direct observation of individual females searching on simple and complex plant structures during 1 hour. Time, frequence and sequence associated to activities and plant parts explored were obtained and analyzed. Plant structure had significant effect on time budget associated to activities (walking, resting, flying) and plant parts explored.
This study demonstrates that plant structure mediates ecological interactions by affecting host finding success and this may have important implications in population dynamics, evolution of hosts and parasitoids but also in biological control programs.

Desenvolvimento pós-embrionário de Caligo illioneus (Cramer, 1775) (Lepidoptera, Nymphalidae, Brassolinae) alimentando-se de folhas de Heliconia bihai (L.) L. (Heliconiaceae), em laboratório. Este estudo foi desenvolvido visando os seguintes aspectos: a determinação dos estádios (duração de instares, em dias) dos períodos larval e pupal; a razão sexual e a viabilidade dos ovos, em condições de laboratório. Ovos e larvas de C. illioneus foram coletados em folhas de H. wagneriana Petersen e acompanhados em laboratório para o registro dos eventos biológicos (eclosão, ecdises, mortes, pupação e emergência dos adultos) e observação do com portamento de cinco larvas. O período pós-embrionário teve uma duração (média ± erro-padrão), em dias de 54,58 ± 0,44. O período larval foi de 40,00 ± 0,43 dias, sendo representado por cinco instares: L1= 7,88 ± 0,23; L2= 6,42 ± 0,16; L3= 5,19 ± 0,25; L4= 7,04 ± 0,19 e L5= 13,46 ± 0,28 (sendo o período larval ativo de 12,46 ± 0,28, seguido de apenas um dia de prepupa). O período pupal foi de 14,58 ± 0,20 e o período inativo do desenvolvimento pós-embrionário foi de 15,58 ± 0,20. Ao final do acompanhamento, foram obtidos 26 adultos (razão sexual de 0,46), o que representou uma viabilidade de 56,52% do total de ovos e de 76,47% dos neonatos obtidos. A análise morfométrica demonstrou que a indicação da fase de desenvolvimento larval de C. illioneus pode ser realizada com base na largura das cápsulas cefálicas, considerando os seguintes intervalos (em mm): L1= 1,457―1,605; L2= 1,951―2,272; L3= 3,139―3,488; L4= 4,970―5,600; L5= 7,423―8,557). Os agentes de controle biológico que naturalmente parasitaram os imaturos (ovo e pupa) da espécie C. illioneus foram parasitóides de pupa: Conura maculata (Fabricius, 1758) (Hymenoptera: Chalcididae: Chalcidini) e um único pupário de Diptera. Apenas um ovo estava parasitado por espécimes da família Eulophidae (Hymenoptera).

Larvae of Geometridae (Lepidoptera) were obtained with an entomological umbrella, from October 2013 to September 2015, in two areas of semi-deciduous forest (Mata/Cerradão and Mata) at Estação Ecológica de Jataí, Luiz Antônio, São Paulo state. The larvae of Geometridae were kept in the laboratory until the adult or parasitoid emergence. Especimens of the families Braconidae and Ichneumonidae were obtained, from January 2014 to February 2015, with two Malaise traps located in the same local of collection of Geometridae larvae. The material obtained in the Malaise traps was sorted, the individuals of the families Braconidae and Ichneumonidae were identified in subfamily level and the Microgastrinae, Cheloninae and Rogadinae, Campopleginae and Mesochorinae subfamilies were identified at the genus level. A total of 416 larvae of Geometridae weas collected, 190 in the Mata/Cerradão stretch and 226 in the Mata stretch, of which, 52 and 39, respectively, were parasitized. Among the Geometridae, the subfamily Ennominae was represented by individuals of 14 genera (Argyrotome, Glena, Hymenomima, Iridopsis, Ischnopteris, Lomographa, Macaria, Nepheloleuca, Patalene, Phrygionis, Physocleora, Prochoerodes, Rhomboptila and Trotopera), the subfamily Larentiinae by four (Eubaphe, Eupithecia, Euphyia and Pterocypha) and the subfamily Sterrhinae by two (Cyclophora and Idaea). A total of 91 larvae of Geometridae, from 11 genera, were obtained parasitized by 198 parasitoids. The parasitoids obtained belong to the families Braconidae, Ichneumonidae, Eulophidae and Diptera. The Malaise traps provided 2720 individuals of the Ichneumonoidea superfamily, of these 1210 are Braconidae and 1510 are Ichneumonidae, in the Mata/Cerradão stretch, and 702 in the Mata stretch, of which 214 individuals of the Braconidae family and 488 individuals of the Ichneumonidae family. Among the Braconidae, the subfamily Microgastrinae was the most abundant, with 44.5% of individuals in the Mata/Cerradão stretch and 31.8% in the Mata stretch. Eighteen genera of Microgastrinae were recorded (Alphomelon, Apanteles, Choeras, Cotesia, Diolcogaster, Distatrix, Glyptapanteles, Hypomicrogaster, Iconella, Microplitis, Papanteles, Parapanteles, Pholetesor, Prasmodon, Promicrogaster, Protapanteles, Pseudapanteles and Rasivalva), five of Rogadinae (Aleiodes, Choreborogas, Rogas, Stiropius and Yelicones) and four of Cheloninae (Ascogaster, Chelonus, Microchelonus and Phanerotoma). Between the Ichneumonidae collected, 161 individuals were obtained from the subfamily Campopleginae in the Mata/Cerradão stretch and 35 in the Mata stretch. The genera of Campopleginae obtained were Campoletis, Campoplex, Casinaria, Charops, Cryptophion, Cymodusa, Diadegma, Dusona, Hyposoter, Microcharops and Venturia.
Larvas de Geometridae (Lepidoptera) foram obtidas por meio de guarda-chuva entomólogico, no período de outubro de 2013 a setembro de 2015, em duas áreas de mata estacional semidecídua (transecto Mata/Cerradão e transecto Mata) na Estação Ecológica de Jataí, Luiz Antônio, São Paulo. As larvas de Geometridae foram mantidas em laboratório até a emergência do adulto ou do parasitoide. Exemplares das famílias Braconidae e Ichneumonidae foram obtidos, no período de janeiro de 2014 a fevereiro de 2015, por meio de duas armadilhas Malaise localizadas nos mesmos transectos de coleta das larvas de Geometridae. O material obtido nas armadilhas Malaise foi triado, os indivíduos das famílias Braconidae e Ichneumonidae foram identificados em nível de subfamília e as subfamílias Microgastrinae, Cheloninae e Rogadinae, Campopleginae e Mesochorinae foram identificados em nível de gênero. Foram coletadas 416 larvas de Geometridae, 190 no transecto Mata/Cerradão e 226 no transecto Mata, das quais, 52 e 39, respectivamente, estavam parasitadas. Entre os Geometridae, a subfamília Ennominae foi representada por indivíduos de 15 gêneros (Argyrotome, Cimicodes, Glena, Hymenomima, Iridopsis, Ischnopteris, Lomographa, Macaria, Nepheloleuca, Patalene, Phrygionis, Physocleora, Prochoerodes, Rhomboptila e Trotopera), a subfamília Larentiinae por quatro (Eubaphe, Eupithecia, Euphyia e Pterocypha) e a subfamília Sterrhinae por dois (Cyclophora e Idaea). Foram obtidas 91 larvas de Geometridae, de 11 gêneros, parasitadas por 198 parasitoides. Os parasitoides obtidos pertencem às famílias Braconidae, Ichneumonidae, Eulophidae e Diptera. As armadilhas Malaise forneceram 2720 indivíduos da superfamília Ichneumonoidea, destes 1210 Braconidae e 1510 Ichneumonidae, no transecto Mata/Cerradão e 702 no transecto Mata, dos quais 214 indivíduos da família Braconidae e 488 indivíduos da família Ichneumonidae. Entre os Braconidae, a subfamília Microgastrinae foi a mais abundante, com 44,5% de indivíduos no transecto Mata/Cerradão e 31,8% no transecto Mata.

Повний текст джерелаThe objective of this research was to evaluate biological parameters of A. kuehniella in artificial diets with composition variations, aiming to optimize its mass rearing, increasing the quantity and the quality of the produced eggs for Trichogramma spp. rearing. The research was divided into two phases. In the first one, biological parameters of A. kuehniella reared on artificial diets composed of whole wheat flour of 6 different varieties (97%) and yeast (3%) was evaluated; the tested varieties was Coodetec 150 (control), BRS Parrudo, BRS Guamirim, BRS 327, BRS 328 and BRS 374. In the second phase, the same parameters was evaluated on diets composed of wheat and yellow corn flour alone (100%), whole wheat flour (50%) and yellow corn flour (50%), and different proportions of yeast added to the wheat flour (3%, 5% and 8%). The evaluated biological parameters for both phases were: duration (days) and viability (%) of egg-adult period, adult male and female weights (mg), sex ratio, adult male and female longevity (days), daily rhythm of oviposition and viability of the produced eggs. It was concluded that the A. kuehniella eggs production is not correlated to the wheat variety used as component of the artificial diet for its rearing; the best artificial diets for the mass rearing of A. kuehniella are those composed by whole wheat flour (97%) and yeast (3%) (diet 1), whole wheat flour (50%) and yellow corn flour (50%) (diet 2) and whole wheat flour (100%) (diet 3); with regard to cost-benefit, the lowest cost artificial diet that provides the best development for A. kuehniella is that composed by whole wheat flour (100%).

Повний текст джерелаKoinobiont parasitoids regulate the growth and development of their hosts in order to colonize and adequate their host to their own nutritional needs. Parasitoids interfere with several physiological processes at the molecular and cellular levels to regulate their hosts. Thus, this project evaluated the effects of the parasitization by Campoletis flavicincta (Ashmead) (Hymenoptera: Ichneumonidae) on gene expression and protein availability at different stages of parasitization of larvae of the host Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). Comparative gene expression was carried out by RNA-Seq analysis using next-generation sequencing tools (Illumina), with data validation by quantitative real time PCR (qPCR). Protein availability in the host hemolymph was checked by colorimetric and SDS-PAGE assays. Protein changes in the hemolymph were verified throughout parasitoid development at 1, 3, 5, 7 and 9 days after parasitization. The parasitoid induced an increase in the total concentration of proteins from day 3 to 9, and induced the precocious synthesis of two proteins (180 kDa and 75 kDa) and their maintenance in the hemolymph until the end of parasitoid development. No parasitism specific proteins were detected. Differential gene expression analysis was concentrated at early parasitization (06, 24 and 72 h), and allowed the identification of 1.189 differentially expressed transcripts. The majority of these transcripts (72.7%) were down-regulated in parasitized larvae as compared to the nonparasitized. Analysis of the differentially expressed transcripts led to the identification of functionally important transcripts for the parasitoid development, belonging to i) sugar metabolism, ii) storage proteins, iii) hormone synthesis and degradation, and iv) immune response. qPCR experiments using selected transcripts validated the differential expression observed in RNA-Seq experiments. Additional analysis using the de novo transcriptome assembly also led to the identification of 22 transcripts associated with the genome of the polydnavirus of C. flavicincta distributed in four gene families: vankyrin, repeated-element, cysteine-motif and N-family. These transcripts had specific temporal patterns of expression, with the transcripts from vankyrins and cysteine-motif being the most abundant.

Resumo: As larvas de Eunica bechina (Lepidóptera; Nymphalidae) se alimentam das folhas jovens do pequi Caryocar brasiliense (Caryocaraceae), uma planta que apresenta nectários extraflorais (NEFs). Estes nectários são intensamente visitados por muitas espécies de formigas forrageadoras de néctar no cerrado brasileiro. As formigas exercem uma forte pressão seletiva nas larvas devido à predação e/ou remoção das lagartas na planta hospedeira. Este estudo examina experimentalmente se a presença de formigas nas plantas de C. brasiliense media as decisões de oviposição por fêmeas de E. bechina. O objetivo foi determinar a importância do espaço livre de inimigos para a seleção de locais de oviposição pela borboleta. Neste estudo desenvolvemos experimentos de oviposição em campo em ramos pareados de uma planta de C. brasiliense, desenhados para testar em campo as preferências da borboleta em relação à presença na planta de diferentes tipos de insetos, incluindo algumas espécies de formigas. A presença de um herbívoro especialista do pequi (Edessa rufomarginata, Pentatomidae), ou de uma formiga não agressiva e visitante da planta (Cephalotes pusillus), não influenciaram a oviposição por fêmeas de E. bechina quando comparadas com ramos sem insetos (controle). Por outro lado, detectamos uma redução significativa na freqüência de oviposição em ramos com qualquer uma de duas espécies de formigas do gênero Camponotus quando comparado com ramos controle sem insetos. A tendência de evitar locais da planta ocupados por formigas agressivas não foi afetada com o incremento na demanda de galhos para oviposição pelas fêmeas da população. Sugerimos que as fêmeas de E. bechina utilizam características como forma e tamanho dos insetos como sinais de reconhecimento para mediar a decisão de oviposição. O comportamento das fêmeas de evitar ramos com formigas agressivas pode reduzir a mortalidade da prole sobre a planta hospedeira Esta capacidade de discriminação, além de um conjunto de defesas morfológicas e comportamentais das larvas, aparentemente é fundamental para permitir à E. bechina se especializar em uma planta defendida por formigas tal como o pequi
Abstract: Larvae of Eunica bechina Lepidoptera (Nymphalidae) feed on young leaves of Caryocar brasiliense (Caryocaraceae), a shrub bearing extrafloral nectaries that is intensively visited by many nectar-gathering ant species in the Brazilian cerrados. Visiting ants exert strong predation pressure on the caterpillars of E. bechina on the host plant. This field study examines experimentally whether ant presence on C. brasiliense shrubs mediates oviposition decisions by E. bechina females. The aims of this study were to determine the importance of an enemy-free space for the selection of plant locations for oviposition by the butterfly. Oviposition experiments on paired branches of C. brasiliense were designed to test egg-laying preference by Eunica in relation to the presence or absence of different types of insects on the plant. Field experiments demonstrated that presence of a specialist insect herbivore of Caryocar (Edessa rufomarginata, Pentatomidae), or of the non-aggressive visiting ant Cephalotes pusillus, had not effect on oviposition by E. bechina females compared to insect-free control branches. On the other hand, there was a significant reduction in oviposition frequency on branches with either of two aggressive ant species of the genus Camponotus compared to insect-free control branches. Avoidance of plant locations occupied by such aggressive ants persists even under high levels of oviposition sites demand by the females of the local population. We suggest that E. bechina butterflies use ant traits such as size and form as visual recognition cues to mediate oviposition decisions. By doing so, the egg-laying female reduces the probability of larval offspring encountering aggressive ants on the host plant. This discrimination capacity, in addition to an array of behavioral and morphological defenses of the caterpillars, is apparently crucial to permit the butterfly to specialize on such a risky, ant-defended host plant

Повний текст джерелаAscia monuste (Lepidoptera, Pieridae) caterpillars are Brassicaceae specialists, being one of the most important comsumers of this plant family in the Neotropical region. In the field, a high proportion of immatures migrates to other hosts in order to develop properly, probably facing some variation in terms of nutritional value and location of their hosts. The main objective of this study was to investigate how the feeding of caterpillars of same ontogenetic phase on different hosts [kale (Brassica oleracea L. var. acephala) and rucola (Eruca sativa L.), and kale and cabbage (Brassica olerace L. var. capitata)], affects the corresponding performance of A. monuste. The hosts above mentioned differ in their nitrogen content: kale and rucola have similar nitrogen quantity, and kale has higher quantity than cabbage. In addition, it was evaluated whether the previous host would influence food choice in subsequent larval instar, in the field and in laboratory, as well as the effects of 24 hours of food deprivation on immature performance before switching the host. Beside few differences caused by host switching, possibly by the differences in nutrient levels, all the feeding tests originated similar performances and viable adults. When the preference was determined by the first caterpillar ingestion, previous experience did not influence host choice: caterpillars chose rucola instead of kale, and kale instead of cabbage, independently of previous host. But, when preference was determined by the total amount of ingested food, previous experience acted as a fagoestimulant in kale and rucola as hosts. It was not possible to detect what determine larval preference in the field. All plants tested were attractive for the caterpillars and the migration may occur for hosts that are close and easier to find. The 24 h food deprivation did not increase the effects of host change, but did present some differences. Rucola and cabbage could be less adequate hosts on final instars, because pupae whose larvae ingested these crucifers presented, in general, less pupal mass and also less oocytes, even when food deprivation does not occured.
