  • Abstract: ong>Effect of the insect growth regulator, hydroprene, was observed on Callosobruchus maculatus (F.). Hydroprene was applied topically to the last 2–3 sternites of unmated males and females with a micropipette. No significant decrease in fecundity was observed even with the highest dose of 0.75 μg of hydroprene, whereas the fertility of the eggs laid by treated females was affected on the first day of the oviposition period even with the lowest dose of 0.1 μg, and the Effect was diluted with time. Male fertility was also affected. The emerged F1 adults showed morphological abnormalities and the developmental period was prolonged.
