Abstract

Three cultivars of pigeonpea (Cajanus cajan) resistant to Heliothis armigera (Hb.) and 3 susceptible ones were grown at 2 plant densities in Andhra Pradesh, India, in 1981-82. Parasitism of the noctuid larvae was higher in the susceptible than the resistant cultivars, averaging 42.5 and 34.5%, respectively, and was higher (36.7-47.4%) at 13.3 plants/m2 than at 4.4 plants/m2 (32.7-36.0%). The influence of the cultivar was greater in October-November (when Carcelia illota (Curr.) was the dominant parasite) than in January (when Goniophthalmus halli Mesnil predominated)
