Aonla Arthropod Diversity and Management of Its Sucking Insect Pests

The study carried out on "Quantification of arthropod diversity on aonla (Emblica officinalis Gaertn) and management of its major sucking insect-pests" revealed association of a total of 31 arthropods with aonla plant. Among these, 5 belong to sap feeder, 6 defoliator, 2 each gall former and borer, 12 natural enemies, 3 pollinators and one other group of arthropod. Among sap feeders, defoliators, gall formers and borers, respectively, aphid (S. bougainvilliae), leaf binder (T. ziziphy), shoot gall maker (B. stylophora ), bark eating caterpillar (Indarbela sp.) as pest and among natural enemies, lady bird beetles were important.Three species of honeybees were observed visiting on aonla plants as pollinator. Out of 9 treatments including untreated check evaluated against aphid (S. bougainvilliae), imidacloprid @ 40 g a.i./ha was found most effective, however, it was at par with acephate 350g a.i./ha, ethion 40% +cypermethrin 5EC 0.03% and profenofos 50SL, 0.07% after 3 and 10 days of application.
