Insecticidal control for the rice stink bug (Hemiptera: Pentatomidae) complex found in Florida rice.

Abstract

Currently, the rice stink bug complex (Hemiptera: Pentatomidae) attacking Florida rice is the most diversified and unique stink bug complex in United States rice production. This complex includes the common rice stink bug, Oebalus pugnax (F.), and two invasive species, Oebalus ypsilongriseus (DeGeer) and Oebalus insularis (Stal). Insecticidal efficacy for these two invasive species is not known. Insecticidal evaluations of five insecticides were made on adults of both sexes of the three species. Weights of adults were also determined. In all three species, females weighed more than males of the same species. Also, O. pugnax adults were the largest followed by O. ypsilongriseus, with O. insularis being the smallest adults. All five insecticides gave a high degree of control of 93-100% for both sexes of all three species. These data are currently useful to Florida rice growers and may be useful to rice growers in other states if the two invasive species spread to those states. These data also provide baseline data for future studies on development of insecticide resistance of the stink bugs in Florida rice.
