  • comment:

    There were no significant differences in rates of parasitism and predation on eggs of leaffolders (primarily Marasmia patnalis (Bradley) and Cnaphalocrocis medinalis (Guenee)) in transplanted and direct seeded rice. Egg parasitism reached a peak of about 80% in August in both transplanted and direct seeded rice but averaged about 40%. Highest levels of parasitism occurred when predation was lowest. Trichogramma sp. was the most abundant egg parasitoid. At least twelve species of parasitoids emerged from leaffolder larvae. A hyperparasitoid, Eurytoma braconidis (Ferriere), also was collected. Predation on leaffolder eggs reached a maximum of about 85%.
