The three key lepidopteran pests of cole, Brassica oleracea L., crops in North America are diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae); cabbage looper; Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae); and imported cabbageworm, Pieris rapae (L.) (Lepidoptera: Pieridae). Two species-specific pheromone-based experimental attracticide formulations were evaluated against ...

In the present study few indigenous techniques of biodiversity assessment butterflies were practiced in some forest ecosystems Bangladesh. Butterfly-plant interaction a ecosystem is dynamic key factor that determines status forest. A research team Environmental Biology and Biodiversity Laboratory (EBBL) department Zoology, Dhaka University worked successfully on population census forests by usi...

The variability level of the ISSR (inter-simple sequences repeat) primer (GACA)4 was examined in the three Lepidoptera families Pyralidae, Sphingidae and Pieridae. Our study shows that the tetra-repeat (GACA)n is evidently present in sufficient numbers in these butterflies to provide informative DNA fingerprints. The variability is mostly rather high, but within a comparable range to other ISSR...

In present investigations molecular characterization of seven Pieridae butterflies was carried out using four RAPD markers. A total 57 bands were scored with four decamer primers of which 57 were polymorphic and the percentage of polymorphism was 100%. Genus specific bands have been observed i.e. a band of 818bp with primer 12 & 520bp with primer OPP-5. Dendrogram constructed using the NTSYSspc...
