Abstract

The present investigation on “Tritrophic interaction between pigeonpea genotypes, Helicoverpa armigera (Hübner) and natural enemies” was carried out during 2008-12 at ICRISAT (Patancheru, Hyderabad). Under no, dual and multi-choice conditions, egg laying by H. armigera on ICPW 125 was minimum due to high density of type D trichomes, while it was maximum on ICPL 87. The per cent Parasitisation by Trichogramma chilonis Ishii was higher on ICPB 2042 and by Campoletis chlorideae Uchida it was greater on ICPL 87 and ICPL 87091 due to longer pods and clustering type of habitat and ICPL 87119 due to higher pod wall thickness.
