Abstract or Summary
  • This laboratory bioassay focused on lethal and sublethal effects of five insecticides (chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin) and two fungicide treatments (sulfur and a mixture of copper hydroxide and mancozeb) on the predatory mired bug Deraeocoris brevis (Uhler) (Hemiptera: Miridae) using second instars and adult males and females. Formulated pesticides were tested using concentrations that were equivalent to the high label rate (1x) [high rate] and 1/10th of that amount (0.1x) [low rate] dissolved in 378.5L of water. Lambda-cyhalothrin was highly toxic to D. brevis nymphs and adults at both rates, while both rates of novaluron were highly toxic to nymphs. Cyantraniliprole, chlorantraniliprole and novaluron were less toxic to adults and chlorantraniliprole and spinetoram were less toxic to nymphs. Both rates of spinetoram caused significant mortality to adults. Fecundity of adult females was negatively affected by the high rates of either novaluron or spinetoram while the fertility was affected only by the high rate of novaluron. The high rate of spinetoram reduced survival of nymphs. Adults treated with spinetoram had reduced longevity. Cyantraniliprole caused some mortality to nymphs and affected their survival. Both rates of sulfur were toxic to nymphs and affected emergence to adults. The mixture of copper hydroxide and mancozeb was less toxic to D. brevis. Neither adult longevity nor sex ratio was affected by the fungicides. The r values for D. brevis treated with lambda-cyhalothrin, novaluron, spinetoram and sulfur were low, indicating these products may have negative impact on population growth.
