The ovicidal action of five insecticides against egg masses of. M. Javanica was carried out . Isoxation was the most toxic followed by fenamiphos, cyanofos, oxamyl and methomyl. The descending order of the ovicidal activity at the LC 90 level was the same as at the LC so level except of a switch in position between oxamyl and methomyl. This difference was discussed on the basis of the slope values of the toxicity lines. The toxicity of pesticides to the second larval stage at the LC50 level revealed that the nematicides fenamiphos and oxamyl as well as the ovicide isoxathion were the most potent. However cyanofos and methomyl produced moderate toxicity to the larvae.
