Rice Water weevil

Rice Water weevil (Lissorhoptrus oryzophilus Kuschel), originally a native of North America, was first found in the central area of Japan in 1976. By 1990, it had expanded its range into Korea, Taiwan ROC and mainland China.

Rice Water weevil adult and larve can both cause damages to rice. Adult rice water weevils feed on the upper surface of rice leaves, but most economic damage is caused by larvae feeding in or on rice roots.

Control:
1、 Avoid late planting of rice

2、 Water management: Delay the application of permanent flood, but not much past tillering stage of growth. Draining rice fields in the middle of the rice season to decrease the number of larvae and cocoons per rice hill.

3、 Insecticide application: Ethofenprox, Clothianidin, Gamma-cyhalothrin, ets can deal with Rice water weevil adults, which should be controlled at the correct time, that is, before egg-laying occurs. Seed treatment insecticide like Chlorantraniliprole, Clothianidin, Thiamethoxam might perform better.
