Abstract:

The rice water weevil (Lissorhoptrus simplex Say) occurs in large numbers in all rice fields in Arkansas, and is the only generally distributed pest of this crop in this region. The larvae feed on the roots of rice and are frequently charged with causing great damage. In large cage experiments the yield of rice in uninfested cages was approximately 35 per cent greater than it was in cages artificially infested. The loss caused by this insect may be reduced by drainage, at the time the majority of the larvae have entered the third instar and before severe root pruning begins. Drainage should continue until the soil is thoroughly dried.
