Abstract

Biological control agents help regulate pest populations below damaging levels. Telenomus sp. is an egg parasitoid of the rice black bug (RBB), Scotinophora coarctata. This study was conducted to evaluate the efficiency of Telenomus sp. as an egg parasitoid of RBB under laboratory conditions in Midsayap, Cotabato. Results showed that percent parasitism ranged from 82 to 96%. Parasitism was significantly higher (40-70%) with one eggmass per test at 1-4 days after introduction to one mated female parasitoid than with more egg masses (2 to 5/testube). The average number of egg laid by one Telenomus female was 29.
