dc.description.abstractPresent study done during kharif 2013-14 and 2014-15 at the Agricultural Research Farm, Banaras Hindu University, Varanasi evaluates the egg and larval population of Helicoverpa armigera in pigeonpea, as influenced by selected IPM modules. The least egg population was observed with the module M2 (pheromone traps @ 20 + bird perches @ 20 + Bacillus thuringiensis subsp. kurstaki @ 1.0 kg + spinosad 45SC @ 73 g/ ha. As regards larval population, the module M4 (pheromone traps @ 20 + bird perches @ 20 + indoxacarb 14.5 SC @ 60 g a.i. + imidacloprid 17.8 SL @ 20 g a.i. + indoxacarb 14.5 SC @ 60 g a.i./ha) was the one with least numbers. The relationship between egg and larval counts was positive and highly significant in all modules during both the years. © 2020, The Entomological Society of India. All rights reserved.
