Biology and control of fig leaf worm Ocnerogyia amanda Stgr. (Lymantridae: Lepidoptera)
Ekhlas Z. Mohammed
Abstract: The fig leaf worm Ocnerogyia amanda Stgr. from the order Lepidoptera, it began to appear at the beginning of the third week of March, laying 94-140 eggs at night. The eggs hatch from larvae with thick white hairs that cover the entire body of the larva. The larva passes through five larval ages during (18-26) days to turn into a Obtect pupae for a period of (10 -15) days for the complete insect to come out and repeat the life cycle, and the length of the female's lifespan is (5-10) days and the male's (2-6) days. The study showed that Malathion had the best effect on the third instar larvae, followed by Davey Coz, then Vinam, and the least effect was abamectin. When sesame oil was mixed with pesticides , the toxicity of the three pesticides (Malathion, Devi Coz and Vinam) was synergism . The synergistic ratio was (1.57, 1.35 and 1.32), respectively, and no effect on abamectin.
