Abstract

A two-year study was conducted to evaluate toxicological responses of false chinch bug (FCB), Nysius raphanus (Howard), to selected insecticides in the laboratory bioassays. A chlorpyrifos resulted in the lowest LC50 and highest mortality in both years. Diazinon showed the second lowest LC 50 in first year, but not the following year. A cyfluthrin and lambda-cyhalothrin resulted in moderate effectively insecticides. However, a spinosad resulted in the highest LC50 and lowest mortality in the first year. Permethrin showed the lower LC50 and higher mortality than lambda-cyhalothrin and esfenvalerate in the following year. A diazinon and endosulfan also resulted in significant low LC50 and significant mortality on FCB. The highest LC50 and lowest mortality observed with imidacloprid. © 2007 Academic Journals.
