Abstract

Abstract – Population fluctuation studies are very important for pest control, since they provide fundamental information on when and in what intensity a harmful organism can arise in crops, thus providing a greater accuracy in the application of control measures. The population fluctuation of the South American rice water weevil (Oryzophagus oryzae), of the rice stink bug (Oebalus spp.), and of the rice caseworm (Nymphula spp.) in irrigated rice fields were related to the crop management. For these species, control measures can be planned and implemented based on population fluctuation studies.
