The toxicity of two biorational insecticides, spinosad (Tracer) and methoxyfenozide (RH-2485), was tested against eggs, larvae, and pupae of the noctuid Spodoptera littoralis (Boisduval). In the first experiment, filter paper circles containing egg masses of two different age classes, young (<24 h old) and old (24-48 h old), were dipped in different concentrations of each insecticide diluted in either water or acetone. No ovicidal activity was recorded when insecticides were diluted in water.

- The study assessed the effects of seven modern insecticides on the lepidopteran parasitoid Hyposoter didymator, focusing on its susceptibility and various life parameters.
- At recommended field doses, methoxyfenozide and tebufenozide were safe, while diflubenzuron showed moderate toxicity, and azadirachtin, pyriproxyfen, and spinosad were very toxic, severely affecting the parasitoid's survival and reproduction.
- The research also evaluated the compounds' absorption and retention in H. didymator, finding that diflubenzuron had the highest absorption, indicating the need for careful evaluation of using certain insecticides in pest management programs involving this parasitoid.
