The male of Hymenoepimecis japi (Hymenoptera, Ichneumonidae, Pimplinae) is described and illustrated. The specimen was collected in a modified web (cocoon web) of Leucauge roseosignata (Araneae, Tetragnathidae) made in a laboratory. Both, host and parasitoid were collected in Reserva Biológica Serra do Japi, located in Jundiaí, São Paulo, Brazil.
An attempt was made to rear the eri silkworm, Philosamia ricini on leaves of caster and reared under laboratory condition. It observed that is a primary potential host silkworm. The growth parameters cocoon characters silkworm were normal. successfully lasted its life cycle ranged from 38 40 days. effective rate rearing, weight pre-spinning larvae, cocoon, shell pupae 70 75 per cent, 6 7 g, 3.0...
This article presents the analysis of methods preliminary treatment live cocoons and de-animation sponges currently used in our republic.

The aim of this study is to investigate the utilization of silkworm cocoon waste, such as pierced or stained cocoons, as a sorbent material for the removal of motor and vegetable oils from water. The oil-sorption capacity, rate and reusability of the material were evaluated. The results show the high sorption capacity of the silkworm cocoon waste sorbent (42-52 g(oil)/g(sorbent) for motor oil a...
