Field studies in Orissa, India, in 1979-81 showed that the egg-larval parasite Platygaster oryzae and the pupal parasite Neanastatus grallarius acting alone or together had a significant controlling effect on the rice pest Orseolia oryzae. However, N. grallarius often behaved as a facultative hyperparasite of P. oryzae, and larvae of the carabids Casnoidea interstitialis and C. indica also attacked the platygasterid.
