Abstract

For evolving an eco-friendly, non-toxic and practically feasible method of minimizing attack of the most serious insect pest, the Teak skeletonizer Eutectona machaeralis (Walk.), four egg parasitoids viz. Trichogramma brasiliensis Ashmead; T. chilonis Ishil.; T.  pretiosum Riley and T. japonicum Ashmead, were tested in laboratory conditions. The result proved that T. brasiliensis was a potential species to parasitise maximum number i.e. 58 to 61 per cent of host eggs in laboratory.  Field evaluation of the wasps of T. brasiliensis in different quantity proved that introduction of this egg parasitoid @ 1.25 to 3 lakhs wasps/ ha was equally and highly effective to minimize the attack of Teak skeletonizer, E. machaeralis.
