How to scout for colaspis in rice - video [Image: colaspis larva] For several years Arkansas rice farmers have had to deal with grape colaspis, a small beetle, whose larvae feed on the roots of rice. Rice drilled into soybean stubble is particularly susceptible to damage from this insect. Larval feeding can cause more than 50 percent reduction in stand. This season colaspis has caused stand reductions in a few rice fields in Acadia, Evangeline and St. Landry parishes. This short video will train you to scout for colaspis in rice. (Runtime: 3:58) How to Scout for Rice Water Weevils - video [Image: Rice water weevil adult] The rice water weevil (RWW) is the most important early-season insect pest of rice in Louisiana. Adults of this insect emerge from overwintering sites beginning in early April in southern Louisiana (later in northern Louisiana) and fly to rice fields, where they feed on young rice leaves. Egg-laying commences when standing water is present in fields. This video will train you to scout for RWW larvae & adults in your rice field.
