Out of ten pigeonpea genotypes, four genotypes were found least susceptible to lepidopteran
pod borer damage as they showed a damage rating of 4-5 on a Pest Susceptibility Rating Scale of 1-9 (Table 2).

on crops in the Mid-North of Brazil, from 2011 to 2013 and in 2015.
A large presence of miller moths at the study area during the spring of 2002 coincided with the phenology of lepidopterans
in the diet of big brown bats.
Introduction of cry1Ab gene into cotton (Gossypium hirsutum) enhances resistance against Lepidopteran
pest (Helicoverpa armigera).
An approach to its use in the biological control of lepidopteran
insects behaving as agricultural pests.
CCA was applied to check the effect of different environmental factors on distribution of lepidopterans
(Rana et al.
Abstract: Biological control of lepidopteran
defoliators using parasitoids is a promising alternative.
Our understanding of the factors that explain ecological patterns of lepidopteran
communities such as the spatial and temporal distribution of species is still limited in relatively undisturbed ecosystems (DEVRIES et al,, 2009) and almost inexistent in restored areas (HOLL, 1996; RIES et al.

Hyalophora cecropia, A.
An artificial diet intended for lepidopterans
was successfully utilized only after the first generation because the newly hatched larvae had not previously been in contact with any natural food source and artificial diet was readily accepted.
On Crane, the diet was dominated by lepidopterans
, coleopterans, and trichopterans; the spotted cucumber beetle was 5.
This study reports on the isolation of Bt from caterpillar guts, fecal pellets and host plants collected in different protected ecosystems (dry, rain and cloud tropical forests) as a contribution to the better understanding of Bt ecology in relation to lepidopterans
in wildland environments.
