The invasion of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) into the New World has made it possible for this pest to hybridize with a native American species, H. zea (Boddie), under natural conditions. We investigated viability and development hybrids these two species. reared parental species evaluated crosses between males females vice versa, intercrosses hybrids, eight backcrosses estimated length immature stages, fecundity, survival, sex ratio, heterosis.Although hybridization...
Gracillariidae leaf miners include 1987 species of poorly studied micromoths for which the majority diversity has been described from temperate regions. The Neotropics harbors one richest faunas Gracillariidae, but rate taxon descriptions slow because limited sampling and taxonomic activity. In this illustrated catalogue, we provide, first time, 476 high resolution illustrations 201 named gracillariids occurring in region revise their classification, newly considering family-group names...
During recent studies performed in the Atlantic Forest, a new species of Phyllocnistinae (Gracillariidae), Phyllocnistis hemera sp. nov., leaf miner Daphnopsis fasciculata (Thymelaeaceae) was discovered. The adults are described and illustrated as well immature stages, with notes on natural history including description mine. Additionally, DNA barcode sequences were compared to other representatives test for specific status P. infer phylogenetic relationships. This is fifth genus Forest...
Heliozela pitangavora Moreira & Fochezato sp. nov. (Lepidoptera: Adeloidea: Heliozelidae), a leaf miner of Eugenia uniflora L. (Myrtaceae) is described in southern Brazil. Larvae, pupae and adults are characterized using optical scanning electron microscopy, association with data on their life history. Mitochondrial DNA (COI) sequences provided compared closely related species. Individual mines initially appear as small blotches the adaxial surface leaves during summer, progressively...
Larvae of most clearwing moths (Lepidoptera, Sesiidae) are endophagous borers many angiosperms, including their fruits, stems, and roots. Their localized feeding may lead to swellings on those plant parts, but whether the structures produced should be considered true galls is still controversial. In this study we describe a peculiar sesiid moth, Neospheciacecidogena sp. nov. whose larvae induce unusual, external Cayponiapilosa (Vell.) Cogn. (Cucurbitaceae) in Atlantic Forest southernmost...
During a recent survey of leaf-mining microlepidoptera in the Cerrado biome, mines an undescribed Porphyrosela Braun (Lepidoptera: Gracillariidae: Lithocolletinae) were found associated with forage peanut, Arachis pintoi Krapov. W.C. Greg. (Fabaceae). Consequently, adults, immature stages and leaf mine arachisella sp. nov. are herein described based on light scanning electron microscopy. A preliminary analysis DNA barcode sequences including putative members other lithocolletine species all...
O estudo de caso foi realizado numa area degradada situadana varzea do Alto Iguacu, em Araucaria, PR, envolvendo o plantio cincoespecies florestais nativas da regiao, com acompanhamento diario, ondeobjetivou-se apresentar os resultados taxa sobrevivencia apos um mes doplantio. A geral das especies 80,09%, considerado bom. Asespecies Acoita-cavalo (Luehea divaricata), Araca-vermelho (Psidiumcattleianum), Aroeira (Schinus terebinthifolius) e Pitangueira (Eugeniauniflora) apresentaram...
