%X Fenitrothion and aminocarb at concentrations of 0.625-200 ppm caused mortality of Paropsis atomaria eggs of from 12 to 87%, depending on dose and material: fenitrothion was about 20 times more effective than aminocarb. Fenitrothion at doses of 20-6300ng active ingredient per gram of larval fresh body weight also caused more mortality of second- and fourth-instar larvae than aminocarb at the same doses, but the low mortalities prevented conventional probit analysis. Results confirmed that doses used were much lower than those accepted for economic control, but were in the range required for evaluating biological effects on survivors.
