Estimation of avoidable losses caused by the earhead caterpillars on sorghum and their control



Estimation of avoidable losses caused by the earhead caterpillars on sorghum and their control



Entomon 7(1): 65-70



Field trials were conducted for 3 yr (1977-1979) to determine losses caused by earhead caterpillars on sorghum and to compare the relative efficacy of some of the insecticides effective in preliminary trials. Data on decrease in population of earhead caterpillars showed significant reduction in all insecticidal treatments, the order of efficacy being endosulfan > BHC > isofenphos > phenthoate dust > malathion > quinalphos > carbaryl + molasses > phenthoate spray. The average avoidable loss of grain in the insecticidal treatments ranged from 1.71-19.61% as against 44.35% in control. Endosulfan dust followed by BHC and phenthoate dusts and isofenphos spray gave better yields than other insecticides.
