Abstract (sommario):

For all examined species of butterflies and moths (Lepidoptera), common peculiarities of larval molts are revealed, which distinguish them from all other insects: with the molt from one larval instar to another, living tissues of head and thoracic legs undergo significant destruction; the remaining tissues of the head shift backward and are partly impressed into the prothorax, and the remained tissues of the legs are shortened; with the ecdysis, the old head capsule is not broken by the Y-shaped suture, but is shed as a whole. In contrast to the larval molts, the molt from larva to pupa in most lepidopterans (except Gracillarioidea) passes without shifting of the head and legs tissues, and the cuticle of head capsule breaks by the Y-shaped suture. Peculiar adaptations allow lepidopteran larvae to live through long-term immobility of the head and the legs during each molt which separates two active larval instars. The set of species examined by us allows to express a statement that the peculiar mode of larval molt is inherent to all lepidopterans and differentiates them from all other insects, i. e. is an autapomorphy of the order Lepidoptera.

Abstract (sommario):

Quercus L., dominate almost 40% of Iran’s forest area. The second destructive group of insects is defoliator Lepidoptera distributed in the Zagros forests of Iran. We assessed Lepidoptera communities in Zagros forests ecosystems in Lorestan province, western Iran during a ca. 2-yr period that coincided with defoliation outbreaks experienced by this area. A number of 500 lepidopteran larva feeding Quercus leaves handy were collected. The phylogenetic relationship of Lepidoptera was analysed using BEAST software based on the Bayesian Inference method. In total, 14 lepidopteran taxa were identified based on DNA sequences of their immature stages. Six genera and eight species were identified using BLASTn. Here we developed a COI barcoding-based approach to Lepidoptera species delimitation.

Abstract (sommario):

Abstract Vision is underpinned by phototransduction, a signaling cascade that converts light energy into an electrical signal. Among insects, phototransduction is best understood in Drosophila melanogaster. Comparison of D. melanogaster against three insect species found several phototransduction gene gains and losses, however, lepidopterans were not examined. Diurnal butterflies and nocturnal moths occupy different light environments and have distinct eye morphologies, which might impact the expression of their phototransduction genes. Here we investigated: 1) how phototransduction genes vary in gene gain or loss between D. melanogaster and Lepidoptera, and 2) variations in phototransduction genes between moths and butterflies. To test our prediction of phototransduction differences due to distinct visual ecologies, we used insect reference genomes, phylogenetics, and moth and butterfly head RNA-Seq and transcriptome data. As expected, most phototransduction genes were conserved between D. melanogaster and Lepidoptera, with some exceptions. Notably, we found two lepidopteran opsins lacking a D. melanogaster ortholog. Using antibodies we found that one of these opsins, a candidate retinochrome, which we refer to as unclassified opsin (UnRh), is expressed in the crystalline cone cells and the pigment cells of the butterfly, Heliconius melpomene. Our results also show that butterflies express similar amounts of trp and trpl channel mRNAs, whereas moths express ∼50× less trp, a potential adaptation to darkness. Our findings suggest that while many single-copy D. melanogaster phototransduction genes are conserved in lepidopterans, phototransduction gene expression differences exist between moths and butterflies that may be linked to their visual light environment.

Abstract (sommario):

Lepidopteran community and its parasitoid on cucumber field in Bogor, Sukabumi and Cianjur District, West Java. Cucumber is one of horticultural commodities that are widely cultivated in Indonesia, but information related to Lepidoptera pests and their parasitoids are limited. The aim of this study was to obtain information about Lepidopteran community on cucumber and their parasitoid diversity. Lepidopteran larvae were collected from 16 cucumber sites in the District of Bogor, Sukabumi and Cianjur in November 2014 until May 2015. Larvae were collected from each cucumber plant follow along 60 m transects. Larvae were collected from the field then brought to the laboratory. All larvae were then reared on cucumber leaves until pupation and parasitoids emerged. The data obtained were tested by analysis of the mean and analysis of variance (One way ANOVA) using the program R Stat. The results showed that cucumber plants were attacked by six species (morphospecies) belonging to four families of Lepidoptera. Diaphania indica (Saunders) (Lepidoptera: Crambidae) is the most abundant species found. All species (morphospecies) of Lepidoptera are more common when the cucumber plants are in the generative growth stage. Our result further showed that D. indica was attacked by 9 parasitoid larvae and 3 parasitoid pupae, C. chalcites (Lepidoptera: Noctuidae) by 5 parasitoids dan S. litura (Lepidoptera: Noctuidae) by 2 parasitoids. A braconid, Apanteles taragamae, is the most common parasitoid of D. indica found in the field. Its parasitism rate can reach 27% in the field. Overall, this research revealed that a number of parasitoids, that were found attacking Lepidopteran on cucumber indicates their potential use as biological control agents in this agroecosystems.

Abstract (sommario):

Lepidoptera is one of the most speciose insect orders, causing enormous damage to agricultural and forest crops. Although genome editing has been achieved in a few Lepidoptera for insect controls, most techniques are still limited. Here, by injecting female pupae of the Lepidoptera model species, Bombyx mori, gene editing was established using the Receptor-Mediated Ovary Transduction of Cargo (ReMOT) control technique. We identified a B. mori oocytes-targeting peptide ligand (BmOTP, a 29 aa of vitellogenin N-terminal of silkworms) with a highly conserved sequence in lepidopteran insects that could efficiently deliver mCherry into oocytes. When BmOTP was fused to CRISPR-associated protein 9 (Cas9) and the BmOTP-Cas9 ribonucleoprotein complex was injected into female pupae, heritable editing of the offspring was achieved in the silkworms. Compared with embryo microinjection, individual injection is more convenient and eliminates the challenge of injecting extremely small embryos. Our results will significantly facilitate the genetic manipulation of other lepidopteran insects, which is essential for advancing lepidopteran pest control.

Biological activity of entomopathogenic actinomycetes against lepidopteran insects (Noctuidae: Lepidoptera). Can. J. Plant Sci. 94: 759–769. The aim of the present study was to identify an efficient broad-spectrum bio-pesticide for the control of lepidopteran insects from microbes in various ecological niches. A total of 111 microbes isolated from various herbal vermi-composts and organically cultivated fields were evaluated for their intracellular metabolites (ICM), extracellular metabolites (ECM) and whole culture (WC) against early instars of lepidopteran insects. Fifteen actinomycete isolates which showed insecticidal activity against 2nd instar Helicoverpa armigera were selected and further screened against Spodoptera litura and Chilo partellus. A significant broad spectrum insecticidal activity was found in the order ECM>ICM>WC against all the insects under laboratory conditions. All these actinomycete isolates also registered significant activity under greenhouse conditions on 2nd instar H. armigera. The actinomycete isolates were identified by 16S rDNA sequencing and matched with Streptomyces species using BLAST search. Among all the 15 isolates, SAI-25 (S. griseoplanus), CAI-155 (S. bacillaris) and BCA-698 (S. albolongus) showed consistent entomopathogenic activity against all the three insects suggesting their potential as broad-spectrum biocontrol agents against other lepidopterans.

Abstract (sommario):

The Mesozoic history of Lepidoptera and Trichoptera is reviewed and their phylogeny traced back to early Mesozoic specialized Permochoristidae Mecoptera. Queensland emerges as the center of origin for the earliest Lepidoptera and Trichoptera and is also the region where the first lepidopteran hostplants, primitive dicot angiosperms, arose from Glossopteridae, probably at the Triassic–Jurassic boundary. Protomecoptera evolved from extinct Protoblattodea (not Neuroptera) during Late Carboniferous or Early Permian time. The first Lepidoptera, terrestrial Agathiphagidae, evolved from aquatic Necrotauliidae Trichoptera probably at the close of the Triassic when an extreme drought dried up many streams. The very small size of Amphiesmenopteran Mecoptera and the first Trichoptera and Lepidoptera fossils obeys Cope's Rule.

Abstract (sommario):

In the present study, we sequenced the complete mitochondrial genome (mitogenome) of Agrius convolvuli (Lepidoptera: Sphingidae) and compared it with previously sequenced mitogenomes of lepidopteran species. The mitogenome was a circular molecule, 15 349 base pairs (bp) long, containing 37 genes. The order and orientation of genes in the A. convolvuli mitogenome were similar to those in sequenced mitogenomes of other lepidopterans. All 13 protein-coding genes (PCGs) were initiated by ATN codons, except for the cytochrome c oxidase subunit 1 (cox1) gene, which seemed to be initiated by the codon CGA, as observed in other lepidopterans. Three of the 13 PCGs had the incomplete termination codon T, while the remainder terminated with TAA. Additionally, the codon distributions of the 13 PCGs revealed that Asn, Ile, Leu2, Lys, Phe, and Tyr were the most frequently used codon families. All transfer RNAs were folded into the expected cloverleaf structure except for tRNASer(AGN), which lacked a stable dihydrouridine arm. The length of the adenine (A) + thymine (T)-rich region was 331 bp. This region included the motif ATAGA followed by a 19-bp poly-T stretch and a microsatellite-like (TA)8 element next to the motif ATTTA. Phylogenetic analyses (maximum likelihood and Bayesian methods) showed that A. convolvuli belongs to the family Sphingidae.

Abstract (sommario):

Abstract Agricultural pest infestation is as old as domestication of food crops and contributes a major share to the cost of crop production. In a transgenic pest control approach, plant production of Vip3A, an insecticidal protein from Bacillus thuringiensis, is effective against lepidopteran pests. A synthetic Vip3A gene was evaluated for efficacy against Spodoptera litura Fabricius (Lepidoptera: Noctuidae; cotton leafworm), Spodoptera exigua Hübner (Lepidoptera: Noctuidae; beet armyworm), Spodoptera frugiperda Smith (Lepidoptera: Noctuidae; fall armyworm), Helicoverpa armigera Hübner (Lepidoptera: Noctuidae; cotton bollworm), Helicoverpa zea Boddie (Lepidoptera: Noctuidae; corn earworm), Heliothis virescens Fabricius (Lepidoptera: Noctuidae; tobacco budworm), and Manduca sexta L. (Lepidoptera: Sphingidae; tobacco hornworm) in tobacco. In artificial diet assays, the concentration required to achieve 50% mortality was highest for H. zea followed by H. virescens > S. exigua > H. armigera > M. sexta > S. frugiperda > S. litura. By contrast, in bioassays with detached leaves from Vip3A transgenic tobacco, the time until 50% lethality was M. sexta > H. virescens > S. litura > H. zea > H. armigera > S. exigua. There was no significant correlation between the artificial diet and transgenic plant bioassay results. Notably, the two insect species that are best-adapted for growth on tobacco, M. sexta and H. virescens, showed the greatest time to 50% mortality on Vip3A-transgenic tobacco. Together, our results suggest that artificial diet assays may be a poor predictor of Vip3A efficacy in transgenic plants, lepidopteran species vary in their sensitivity to Vip3A in diet-dependent manner, and host plant adaptation of the targeted herbivores should be considered when designing transgenic plants for pest control.

Molekuliniai žymenys yra polimorfinės DNR sekos lokalizuotos tam tikrose genomo vietose ir nustatomos naudojant įvairius molekulinės biologijos metodus. Jais nustatomi dviejų ar daugiau idividų ląstelėse esančios genetinės informacijos skirtumai. Morfologiniai žymenys naudojami ir šiandien, bet dėl įvairių trūkumų jų panaudojimas labai ribotas. Įvairūs molekuliniai tyrimo metodai vis dažniau naudojami entomologijoje (Loxdale, Lushai, 1998). Tiriant vabzdžių filogenezę ir sistematiką molekuliniai tyrimo metodai vis populiarėja, tačiau iki šiol jie nebuvo taikomi Tischeriidae ir Elachistidae šeimų drugių tokio pobūdžio tyrimuose.

The benefit of such approaches is undeniable since they will clearly be an asset to rapid biological assessments of poorly known taxa or unexplored areas, and to the discovery of cryptic biodiversity. The Tischeriidae and Elachistidae represent rather small families as compared to many other groups of Lepidoptera. Moths are with wingspan from 6–13 mm. They are found all over the world, but most species are known from Boreal, Palearctic and Neotropical regions. These moths are leaf-miners during all larval instars. Molecular tools can help to identify this group. A lot of Tischeriidae and Elachistidae species are siblings externally, and their identification is very problematic, so in this case the structure of the male genital is more popular.

Abstract (sommario):

Os Charaxinae, subfamília de borboletas pertencente à família Nymphalidae, são objeto de estudo filogenético nesta tese. Com 20 gêneros válidos e cerca de 330 espécies distribuídos em 6 tribos, a subfamília tem distribuição panbiogeográfica e circuntropical. Neste estudo, foram selecionadas 70 espécies representando todos os gêneros como grupo interno incluído: Coenophlebia archidona, Consul Electra, Consul fabius, Hypna clytemnestra, Polygrapha cyanea, Polygrapha suprema, Polygrapha tyrianthina, Polygrapha xenocrates, Siderone galanthis, Zaretis callidryas, Zaretis isidora, Anaea troglodyta, Fountainea nessus, Fountainea ryphea, Memphis appias, Memphis glauce, Memphis grandis, Memphis hirta, Memphis leonida, Memphis moruus, Memphis philumena, Memphis pithyusa, Memphis polycarmes, Memphis polyxo, Memphis verticordia, Anaeomorpha splendida, Noreppa chromus, Archaeoprepona amphimacus, Archaeoprepona chalciope, Archaeoprepona demophon, Archaeoprepona demophoon, Archaeoprepona licomedes, Prepona praeneste, Prepona laertes, Prepona pheridamas, Prepona pylene, Agrias amydon, Agrias claudina, Euxanthe eurinome, Euxanthe trajanus, Palla decius, Polyura athamas, Polyura delphis, Polyura gamma, Polyura pyrrhus, Polyura jalysus, Polyura schreiber, Charaxes varanes, Charaxes candiope, Charaxes cynthia, Charaxes lucretius, Charaxes jasius, Charaxes tiridates, Charaxes hadrianus, Charaxes nobilis, Charaxes zoolina, Charaxes eupale, Charaxes jahlusa, Charaxes pleione, Charaxes zingha, Charaxes etesipe, Charaxes etheocles, Charaxes nichetes, Charaxes laodice, Charaxes solon, Charaxes latona, Charaxes eurialus, Agatasa calydonia, Prothoe australis e Prothoe franck. Representando o grupo externo foram incluídas três espécies pertencentes a três sufamílias de Nymphalidae: Apatura iris (Apaturinae), Calinaga buddha (Calinaginae) e Amphidecta reynoldsi (Morphinae). Os objetivos deste trabalho são testar a hipótese de monofiletismo da subfamília e apresentar uma hipótese de parentesco para os níveis taxonômicos inferiores à subfamília. Os dados que geraram a matriz de caracteres são baseados em morfologia de adultos e estágios imaturos (quando disponíveis). A metodologia seguiu os princípios da parcimônia com polarização dos caracteres baseada no grupo externo. O monofiletismo da subfamília está corroborado na árvore de consenso por cinco sinapomorfias. Todas as tribos, exceto Preponini, são monofiléticas. Neste caso, Anaeomorpha splendida está mais próxima aos Anaeini, uma questão que necessitaria ainda mais investigações. O agrupamento de Prothoini com os Charaxinae neotropicais é outro resultado que emergiu da análise e muito provavelmente seu posicionamento é basal em relação ao grupo neotropical (Anaeini + Preponini) o que é indicado pela análise com pesagem sucessiva. Alguns gêneros resultaram como polifiléticos como é o caso de Charaxes, Archaeoprepona e Prepona e necessitam revisão taxonômica com base nesta filogenia. Assim, essa análise filogenética deve gerar futuramente revisões nas quais: Charaxes deve incluir as espécies do gênero Polyura, Archaeoprepona deve incluir o gênero monotípico Noreppa e Prepona deve incluir Agrias.
Charaxinae, a butterfly subfamily which belongs to the Nymphalidae, is the subject of this phylogenetic study. With 20 genera and about 330 species in 6 tribes, this subfamily is scattered all around the tropics of the world and is present in all the biogeographic regions. In this work, 70 species of all genera of the Charaxinae subfamily were chosen to represent the in-group: Coenophlebia archidona, Consul Electra, Consul fabius, Hypna clytemnestra, Polygrapha cyanea, Polygrapha suprema, Polygrapha tyrianthina, Polygrapha xenocrates,, Anaea troglodyta, Fountainea nessus, Fountainea ryphea, Memphis appias, Memphis glauce, Memphis grandis, Memphis hirta, Memphis leonida, Memphis moruus, Memphis philumena, Memphis pithyusa, Memphis polycarmes, Memphis polyxo, Memphis verticordia, Anaeomorpha splendida, Noreppa chromus, Archaeoprepona amphimacus, Archaeoprepona chalciope, Archaeoprepona demophon, Archaeoprepona demophoon, Archaeoprepona licomedes, Prepona praeneste, Prepona laertes, Prepona pheridamas, Prepona pylene, Agrias amydon, Agrias claudina, Euxanthe eurinome, Euxanthe trajanus, Palla decius, Polyura athamas, Polyura delphis, Polyura gamma, Polyura pyrrhus, Polyura jalysus, Polyura schreiber, Charaxes varanes, Charaxes candiope, Charaxes cynthia, Charaxes lucretius, Charaxes jasius, Charaxes tiridates, Charaxes hadrianus, Charaxes nobilis, Charaxes zoolina, Charaxes eupale, Charaxes jahlusa, Charaxes pleione, Charaxes zingha, Charaxes etesipe, Charaxes etheocles, Charaxes nichetes, Charaxes laodice, Charaxes solon, Charaxes latona, Charaxes eurialus, Agatasa calydonia, Prothoe australis and Prothoe franck. The out-group consisted of three species from different subfamilies of Nymphalidae: Apatura iris (Apaturinae), Calinaga buddha (Calinaginae) and Amphidecta reynoldsi (Morphinae). The main goal of this work is to test xi the monophyly hypothesis of the subfamily and to present a kinship hypothesis for the lower taxonomic levels. The matrix is composed with morphological data of adult and immature stages (when available). The methodology follows the Principles of Parsimony and the character polarization is based on out-group comparison. The monophyly of the subfamily was corroborated in the Consensus tree by four synapomorphies. All tribes are monophyletic, except for Preponini. In this case, Anaeomorpha splendida is placed with the Anaeini species, an issue that requires more scrutiny. The grouping of Prothoini and the Neotropical Charaxinae is another result derived from this analysis. It is probable that this groupings place in the cladogram is a basal one relative to the Neotropical clade (Anaeini + Preponini). This supposition is supported by successive weighting analisys. Some genera proved to be polyphyletic, and Charaxes, Archaeoprepona and Preponaneed taxonomic revision based on this phylogeny. Thus, Charaxes should include the Polyura species; Archaeoprepona should include the monotipic genus Noreppa; and Prepona should include Agrias in future taxonomic work.

Jais nustatomi dviejų ar daugiau idividų ląstelėse esančios genetinės informacijos skirtumai. Morfologiniai žymenys naudojami ir šiandien, bet dėl įvairių trūkumų jų panaudojimas labai ribotas. Įvairūs molekuliniai tyrimo metodai vis dažniau naudojami entomologijoje (Loxdale, Lushai, 1998). Tiriant vabzdžių filogenezę ir sistematiką molekuliniai tyrimo metodai vis populiarėja, tačiau iki šiol jie nebuvo taikomi Tischeriidae ir Elachistidae šeimų drugių tokio pobūdžio tyrimuose. Šių šeimų drugiai filogenetiškai vieni primityviausių drugių būrio atstovai, jungiantys giminiškas šeimas. Tischeriidae ir Elachistidae drugiai plačiai paplitę tiek Baltijos regione, tiek visame pasaulyje, joms priklauso vieni mažiausių Žemėje mikro drugiai, kurie išsiskiria ne tik archaiška sandara, bet ir labai didele specializacija. Daugelio jų išskleistų sparnų ilgis tesiekia vos 6–13 mm. Daugelis Tischeriidae ir Elachistidae rūšių išoriškai yra panašios ir sunkiai atskiriamos, todėl pagrindinis dėmesys apibūdinant rūšį skiriamas patinų genitalijų struktūrai. Minuojantis gyvenimo būdas – svarbi primityvių Microlepidoptera biologinė adaptacija, suteikusi šiems vabzdžiams daug privalumų. Iki šiol molekulinių tyrimų su šiais drugiais atlikta ypač mažai, todėl visi publikuoti apžvalginiai darbai (tiek Lietuvos autorių, tiek užsienio mokslininkų), iki... [toliau žr. visą tekstą]

Abstract (sommario):

Phylogenetic relationships of 25 genera of Holarctic Teleiodini (Gelechiidae) are postulated based on morphology and molecular characters, including CO?I, CO?II, and 28S genes. The phylogenetic analysis of the morphology matrix yielded six equal most parsimonious trees (length 329 steps, CI = 0.38, RI = 0.53) and a strict consensus tree (length 342 steps, CI = 0.36, RI = 0.50) with two polytomies and two trichotomies. The phylogenetic analysis of the combined morphology matrix and the CO?I + CO?II + 28S matrix yielded two equally most parsimonious trees (length 1184 steps, CI = 0.50, RI = 0.41) and a strict consensus tree (length 1187 steps, CI = 0.50, RI = 0.40) that reinforced results from the morphological analysis and resolved the two polytomies and one of the two trichotomies present in the morphology consensus tree. Teleiodini are defined as a monophyletic clade with a Bremer support value greater than 5 in the consensus tree based on morphology and molecular data. Twenty?three clades of genera are defined with Bremer support values provided. An analyses of larval host plant preferences based on the consensus tree for combined data indicates derivation of feeding on woody hosts from genera feeding on herbaceous hosts and a single origin of feeding on coniferous hosts. An area cladogram indicates five independent origins of Nearctic genera from Holarctic ancestors and one origin from a Palearctic genus. The review of genera includes descriptions of imagos, genitalia, larvae, and pupae with illustrations of selected species. A new genus and a new species from Alabama and Mississippi, United States are described with illustrations of imago, wing venation, and male and female genitalia.

Abstract (sommario):

Revolutions in sequencing technology have provided an unprecedented opportunity to uncover the genetic basis of traits of adaptive importance, enabling researchers not only to merely describe the means of inheritance of traits but also to establish the genetic changes under selection. This thesis examines the loci involved in two recent episodes of strong selection, namely the suppression of Wolbachia-induced male-killing in the butterfly Hypolimnas bolina and the evolution of melanism in moths. H. bolina has evolved the ability to suppress the male-killing effects of the heritable endosymbiont Wolbachia. This thesis demonstrates firstly that this results from a single locus trait that doesn't involve genetic variants beyond chromosome 25. This simple genetic basis explains in part the speed of spread of the suppressor in natural populations. The hypothesis that the insect sex determination gene doublesex is the target of selection is then examined. Compatible with this hypothesis, doublesex variants were found to cosegregate with suppression, and that the peak of a selective sweep is located within doublesex region. An unusual pattern of inheritance was uncovered at the doublesex locus, suggestive of a duplication event. These data are consistent with, though not proof of, Wolbachia driving the evolution of this key sex determination gene. The progression of a selective sweep for the suppression, as it travelled in space across Independent Samoa, was then examined. The sweep across Independent Samoa corroborated the genomic region immediately around doublesex as the target of selection. The sweep was very broad but weakened as it progressed across Samoa. The thesis then examines the genetic basis of melanism in Lepidoptera, and compares the genomic region associated with a naturally selected melanistic form to a laboratory mutant. The 'natural' example corresponded to a known genomic hotspot for colour pattern evolution, whereas this region was excluded in the laboratory mutants. These data support the pleiotropic view of convergence - that involvement of a single region is associated with minimized non-target effects. The thesis ends with a discussion of these data and a programme for future research in the area.

Com a adoção de plantas geneticamente modificadas que expressam toxinas de Bacillus thuringiensis há a necessidade de estabelecimento de estratégias para retardar o desenvolvimento da resistência de insetos, tais como áreas de refúgio. Para tanto, informações sobre a dispersão dos insetos alvo desta tecnologia são essenciais para aprimoramento de técnicas de manejo de insetos-praga. Nos estudos de dispersão normalmente são usadas técnicas de marcação-liberação-recaptura. Assim, objetivou-se com este trabalho marcar Diatraea saccharalis e avaliar a capacidade de dispersão de Spodoptera frugiperda. Para a marcação, dois corantes lipossolúveis em diferentes concentrações (100 a 400 ppm), Sudan Red 7B e Solvente Blue, foram adicionados à dieta artificial de D. saccharalis e avaliados sobre parâmetros biológicos do desenvolvimento de lagartas, pupas e adultos (fecundidade e longevidade). A adição dos corantes em dieta artificial fornecida para alimentação de lagartas de D. saccharalis proporcionou a marcação de adultos e ovos em todas as concentrações testadas. No caso da avaliação da capacidade de dispersão de S. frugiperda foram realizados experimentos durante as safras 2005/2006 e 2006/2007. A dispersão se dá por difusão e foi possível registrar distâncias máximas de recaptura de 806 m para machos e 608 m para fêmeas de S. frugiperda.
With the adoption of genetically modified plants expressing Bacillus thuringiensis toxins there is a need of establishing strategies to delay the development of insect resistance (e.g. refugee areas). Thus, information on target insects dispersal are essential to improve pest management techniques. In dispersal studies, markingrelease- recapture techniques are usually used. The objective of this work was to mark Diatraea saccharalis and evaluate the dispersal capacity of Spodoptera frugiperda. For marking D. saccharalis, different concentrations (100 to 400 ppm) of two oil soluble dyes (Sudan Red 7B and Solvent Blue) were added to larval artificial diet. Larval and pupal development as well as adult fecundity and longevity were evaluated. The addition of dyes into the diet marked both adults and eggs, regardless the concentration used. For evaluating the dispersal capacity of S. frugiperda, experiments were carried out during 2005/2006 and 2006/2007 growing seasons. Dispersal is diffused and the maximum recapture distances were 806 m for males and 608 m for females of S. frugiperda.

Abstract (sommario):

Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), known as tomato moth or tomato leafminer is a microlepidopter from Gelechiidae’s family, which is widely distributed on America, Europe, Africa and Asia and is considered the most important pest of this crop (Roditakis et al. 2010). Phthorimaea operculella granulovirus (PhopGV) has been used for controlling larvae of different moths from Gelechiidae’s family as Tecia solanivora and P. operculella in several countries of South America as Colombia, Brazil, Argentina and Peru, and probably can also be pathogenic for T. absoluta larvae. However, viral isolates from this insect has not been reported nowadays, possibly due to the small larvae size and the difficulty for detecting the virus. In this sense, the aim of the present work was to develop an economic, fast and accurate immunological technique for granulovirus detection in T. absoluta larvae

Cedrela odorata is one of the most important commercial Neotropical forestry species, harvested mainly from natural forest, what have taken the species to danger of extinction. Its commercial plantation is limited by Hypsipyla grandella attacks, which could reach 100% of individuals in a forest plantation (Figure 1). Inverse relation of available calcium concentration in the soil for C. odorata and attacks of H. grandella had been reported (da Silva et al., 2009). Some studies indicate that calcium and boron addition to the soil has a positive e ect in height growth of Swietenia macrophylla (da Silva Junior et al., 2014); nevertheless, some studies suggest that when growth is high there is an increase in attack probability (Newton et al., 1993). Then some clarity on this subject is required.
