MANAGEMENT OF MAJOR MANGO INSECTS AFFECTING FLOWERING AND FRUITING WITH SOME NEWER INSECTICIDES |

| Abstract:
Amritodus atkinsoni (Leth), Erosomyia indica Grover and Rhynhaenus mangiferae Marsh, were the three major insects affecting flowering and fruiting in mango. Experiments conducted during 1981–84 to reduce population and damage of these insects with insecticides indicated that fenvalerate 0.005 per cent, cypermethrin 0.005 per cent, and decamethrin 0.002 per cent gave significantly better control of mango hopper and R. mangiferae. Fenvalerate and cypermethrin, however, were not very effective against midge, E. indica. Fruit yield increased two to three times in all the treatments as compared to control in 1981, 1983 and 1984. In 1982, due to lower pest damage, yield differences were non-significant. Carbaryl was better against midge, hopper and weevil. Endosulfan, although was poor against hoppers, restored the pollinators activity more quickly. Systemic insecticides, dimethoate, monocrotophos, methyl-o-demeton and phosphamidon could not reduce adult R. mangiferae population quickly. | |
