Abstract
Experiments carried out both in laboratory and field indicated that application and timing of methamidophos had significant harmful effect not only on the rice leaffolder Cnaphalocrocis medinalis (Guenee) but also on its natural enemies, such as parasitoids, predatory spiders and Paederus fuscipes. Injury level of rice by the leaffolder could be reduced only within a couple of weeks after spray, and there was no significant difference among the yields of different treatments. Intentionally delayed application of insecticides and increase of action threshold for controlling leaffolder of different generation increased larvae parasitism and had no significant effect on their yields. Because of the stimulation of resurgence of the brown planthopper by spraying drugs in early time, it is recommended that insecticides should be applied judiciously in the early stage, and particularly, the high toxic methamidophos must be banned.
