Abstract

Field studies were carried out by following various standard methods to record the natural enemies of 19 butterfly species during Rabi and Kharif crops amidst agriculture ecosystems of Chamarajanagar District (110401 to 120481 NL and 740521 to 760071 EL) in south Deccan plateau at southern tip of Karnataka State, India. The oviposition and pupation of butterfly species were critically observed for the parasites and predators attack. The death of egg, pupa, larva and adult butterfly species due to parasitoids and spiders was recorded. The parasitoid, Brachymeria jambolana (Hymenoptera: Chalcididae) was more troublesome to the pupa of G. doson and E. core. Around 25 to 27 B. jambolana adult individuals were collected respectively from the pupa of G. doson and E. core. Moreover spider species viz., Selenopes, Zygeilla, Argiope, Hippasa, and Rhene become common predators to 16 butterfly species in this part of the State. Thus, parasitoids and spiders infestation could cause loss to several insect species including protected species like E. core. As natural enemy’s interferences is natural in the wild/open cultivated conditions, it could become one of the major reasons to reduce local butterfly diversity. Hence, there is a dire need to understand about the interaction of parasitoid species with butterfly species which are under threat and whose presence is very essential for the restoration of local biodiversity.
