THE RESIDUAL TOXICITY OF ACTARA AND DECIRIN INSECTICIDES TO ADULTS OF STINK BUG Apodiphus amygdali (Germar) (HEMIPTERA: PENTATOMIDAE)

The present work was undertaken to study the residual toxicity of the two insecticides Actara and Decirin against adult stink bug A. amygdali. The results showed that the type of insecticide, rate of application used and period after spraying of treated trees, all factors influenced the mortality of the adult A. amygdali. Actara gave 37.03% and 80.00% mortality at 0.1 and 2.5 mg/gal. application rates, respectively for 1 day. Decirin gave 33.33% mortality for 1 day at rate of 0.1 ml /gal. water, and rise to 83.33% when application rate rise to 2.5 ml/gal.
