Abstract:
The seasonal incidence of major insect pests on pea Pisum sativum at different growth stages has been assessed in this study. Major pests observed include pea leaf miner Chromatomyia horticola gram pod borer Helicoverpa armigera, blue butterfly Lampides boeticus, pea aphid Acyrthosiphon pisum, Thrips Caliothrips indicus and Cut worms Agrotis sp. The peak incidence of Acyrthosiphon pisum (40.23 larvae/leaf) and percent leaf infestation of Chromatomyia horticola (35.43%) was during 16th SMW, respectively. While the peak incidence of Helicoverpa armigera (0.53 larvae/ plant) and L. boeticus (0.55 larvae/ plant), Caliothrips indicus (0.43) Thysanoplusia orichalcea (0.34) was at 12th SMW. Peak incidence of cut worm (0.35 larvae/plant) was on 9 SMW.
