Description 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.
