Abstract
Pyriproxyfen (Admiral) is an insect growth regulator (IGR) acts as antijuvenile hormone. The present work aims to investigate the toxicological effect of
Pyriproxyfen on both sexes of rust red flour beetle, Tribolium castaneum resulted
from treated 4th larval instar with LC50 value (2.4ppm) and its effect on female
production and male's perception to pheromone. The results indicated that both treated
and untreated sexes could secrete a pheromone that was able to stimulate the opposite
sex as well as its own sex. But production and responsiveness of pheromone in
untreated groups were significantly higher than treated one.
Females secreted a pheromone is a sex pheromone, While the pheromone
secreted by males is an aggregation pheromone.
