Three chordotonal organ modulator insecticides (afidopyropen, pymetrozine and pyrifluquinazon) applied at the low and high label rates were tested for their compatibility with the minute pirate bug, Orius insidiosus, sourced from two commercial suppliers. Acute toxicity was assessed by immersion and forced hydration experiments, and residual toxicity was assessed through leaf surface residual experiments. Mortality and sublethal effects on fecundity were recorded. Data were subjected to Shapiro-Wilk test to detect violation of ANOVA assumptions, and multiple-factor repeated measures ANOVA to detect effects of products, application rates, suppliers, and observation times. In the immersion studies, afidopyropen at the high and low label rates produced the highest mortality among the group 9 insecticides when data was collected at 3 and 24 hours post treatment. Residual studies show that O insidiosus when introduced onto leaf surfaces sprayed 7 days post treatment, each group 9 insecticide at high and low label rates had a mortality rate of less than 25% when data was collected 24 hours after the O. insidiosus had been placed into a holding chamber.
