Adult apterous Myzus persicae , which had fed for 26 h on diet containing azadirachtin at concentrations of 25–100 ppm, produced nymphs at less than half the rate of aphids on control diets. After 50 h on azadirachtin‐treated diets nymph production had virtually ceased. After this period, any nymphs produced by adults that had fed on azadirachtin‐treated diets were born dead with undeveloped appendages. Honeydew production on azadirachtin‐treated diets was unaffected during the first 26 h period but was approximately three times less than on control diets during the subsequent 24 h period.
