Life history and ecology of horogenes chrysostictos gmelin (hymenoptera, ichneumonidae), a parasite of ephestia sericarium scott (lepidoptera, phycitidae)

Abstract: Horogenes chrysostictos Gmelin, a common parasite of lepidopterous larvae, was reared in the laboratory in larvae of Ephestia cautella Walk., E. elutella Walk., E. sericarium Scott, Hofmannophila p...

Establishment and Characterization of Two New Cell Lines (CP - 1268 and CP -169) from the Codling Moth, Carpocapsa pomonella (with a Review of Culture of Cells and Tissues from Lepidoptera)

Abstract: Cell lines have been established from 8 species of Lepidoptera representing 5 different families (Table 2). The line from Antheraea eucalypti (Grace, 1962) was the first insect cell line to be established and is still in culture after 9 1/2 years. The primary explants from which the eight lines originated were larval, pupal, and adult ovaries; larval and pupal hemocytes; and embryonic tissue. Larval, pupal and adult explants seem to follow the same general pattern when cultivated. For a period of several weeks, cell migration or proliferation occurs. Following this initial growth, cell multiplication ceases or decreases drastically. After a period of 6–9 months, cell growth resumes and subculturing may be initiated.

Analyses of an egg recognition kairomone ofTelenomus heliothidis (Hymenoptera: Scelionidae) Isolation and host function.

Abstract: Two large proteins (>330 K) present in the accessory gland ofHeliothis virescens F (Lepidoptera: Noctuidae) serve as an egg recognition kairomone for the parasitoidTelenomus heliothidis Ashmead (Hymenoptera: Scelionidae) Glass beads coated with the isolated proteins were examined and probed by the parasitoid while uncoated glass beads were not Electrophoretic analysis of the contents of theH virescens accessory gland suggests that the gland's contents serve as an egg adhesive Comparison of the gland proteins revealed that theT heliothidis hostHeliothis zea (Boddie) (Lepidoptera: Noctuidae) accessory gland contained the kairomonally active proteins while the nonhostSpodoptera frugiperda (Lepidoptera: Noctuidae) did not

Flying between raindrops: Strong seasonal turnover of several Lepidoptera groups in lowland rainforests of Mount Cameroon.

Abstract: Although seasonality in the tropics is often less pronounced than in temperate areas, tropical ecosystems show seasonal dynamics as well. Nevertheless, individual tropical insects' phenological patterns are still poorly understood, especially in the Afrotropics. To fill this gap, we investigated biodiversity patterns of Lepidoptera communities at three rainforest localities in the foothills of Mount Cameroon, West Africa, one of the wettest places in the world. Our multitaxa approach covered six lepidopteran groups (fruit-feeding butterflies and moths, the families Sphingidae, Saturniidae, and Eupterotidae, and the subfamily Arctiinae of Erebidae) with diverse life strategies. We sampled adults of the focal groups in three distinct seasons. Our sampling included standardized bait trapping (80 traps exposed for 10 days per locality and season) and attraction by light (six full nights per locality and season). Altogether, our dataset comprised 20,576 specimens belonging to 559 (morpho)species of the focal groups. The biodiversity of Lepidoptera generally increased in the high-dry season, and either increased (fruit-feeding moths, Arctiinae, Saturniidae) or decreased (butterflies, Sphingidae) in the transition to the wet season in particular groups. Simultaneously, we revealed a strong species turnover of fruit-feeding Lepidoptera and Arctiinae among the seasons, indicating relatively high specialization of these communities for particular seasons. Such temporal specialization can make the local communities of butterflies and moths especially sensitive to the expected seasonal perturbations caused by the global change. Because of the key role of Lepidoptera across trophic levels, such changes in their communities could strengthen this impact on entire tropical ecosystems.
