ERINNYIS ELLO (LEPIDOPTERA: SPHINGIDAE) (LINNAEUS, 1758): ECOLOGIA, MANEJO E DISTRIBUIÇÃO: PASSADO E PRESENTE

O objetivo do trabalho foi realizar o levantamento populacional e verificar a ocorrência de lepidópteros associados à cultura da mamona no Rio Grande do Sul, Brasil. O estudo populacional foi realizado em cultivos de mamona, cultivar "AL Guarany 2002", implantados na área experimental do Departamento de Solos da Universidade Federal de Santa Maria, em Santa Maria, RS. A semeadura ocorreu na primeira quinzena do mês de novembro de 2006, em uma área de 0,3ha, aproximadamente. As avaliações semanais iniciaram aos 20 dias após a emergência das plantas e persistiram até a maturação das bagas, perfazendo um total de 15 avaliações, sendo as lagartas coletadas manualmente em 40 plantas aleatórias/data de avaliação. Os espécimens coletados foram levados ao Laboratório de Entomologia do DFS/UFSM, onde foram mantidos até a fase adulta. Spodoptera marima Schs. (Lepidoptera: Noctuidae) e Erinnyis ello L. (Lepidoptera: Sphingidae) representaram um percentual de 15,2 e 28,3% do total de lagartas coletadas, respectivamente. Assim, este estudo relata a primeira ocorrência dessas duas espécies de lepidópteros em associação à cultura da mamona no Rio Grande do Sul.

Erinnyis Ello

The aim of this study was to assess the occurrence and identify the egg-parasitoid species of the cassava hornworm (Erinnyis spp.) in cassava plants (Manihot esculenta Crantz - Euphorbiaceae), facilitating their usage in the biological control as a management strategy in the Pará State. During February to December of 2016, cassava hornworm eggs were collected in the Cassava Germplasm Bank area of the Embrapa Amazônia Oriental, located at the city of Belém, State of Pará. In the laboratory, eggs were separated in viable and parasitized and were daily observed until the hatching of the caterpillars and emergence of the parasitoids. The caterpillars were reared until reaching the adult stage and the sex determined at the pupae stage. A total of 482 eggs were collected, with a higher occurrence at March, and 244 caterpillars were obtained with sex ratio of 0.52 with 191 specimens reaching adult stage. Among these adults, 95.81% were Erinnyis ello (Linnaeus) and 4.19% Erinnyis alope (Drury). A total of 1,087 parasitoids were obtained from 131 eggs and belong to four Hymenoptera families: Platygastridae (Telenomus dilophonotae Cameron), Eulophidae (Chrysonotomyia sp. aff. serjaniae), Trichogrammatidae (Trichogramma marandobai Brun, Moraes & Soares) and Encyrtidae (Ooencyrtus sp.). The Erinnyis spp. eggs were mostly parasitized by T. dilophonotae, which was classified along with T. marandobai as constant. The occurrence of these natural enemies highlights the potential for natural biological control against Erinnyis spp.

Calcium Precipitation

Subcellular fractions of the cells from the first and last third of midguts from Erinnyis ello caterpillars were obtained by conventional homogenization, followed by differential centrifugation or differential calcium precipitation, as well as by partial ultrasonic disruption. Aminopeptidase was enriched in the subcellular fractions, which in the electron microscope display mainly microvilli from the columnar cells (obtained by differential centrifugation and ultrasonic disruption), and also in the microvilli fraction obtained by differential precipitation. To account for the enzyme activities that sedimented with vesicles displaying brush borders, major amounts of the soluble glycosidases (cellobiase, N-acetylglucosaminidase, maltase, and trehalase) are assumed to be loosely bound to the cell glycocalyx, from where they are set free by homogenization and (or) freezing–thawing. Intracellular glycosidases seem to be bounded by membranes, which sediment together with vesicles that resemble secretory vesicles. The soluble form of amylase occurred mainly associated with the microvilli of anterior midgut cells and is supposed to be contained inside small vesicles, which are seen budding along columnar cell microvilli and fusing one with the other and with the tips of the microvilli from the anterior midgut cells. Secretory mechanisms are discussed in the light of the evidence that the posterior midgut secretes whereas the anterior midgut absorbs water.
