Abstract

The aggregation pheromone components Z-2-octene-2-methyl decanal (M1) and 4,5-dimethyl decanal (M2) were isolated from the natural pheromone of males of Tribolium castaneum and bioassayed separately, in combinations, and with other compounds against the stored products pest. A blend of M1 and M2 at a ratio of 1:2 induced maximum aggregation of 86% of mixed adults at 21 h. Neither the pheromone blend nor its components individually possessed sex pheromone activity. The olefinic bond in M1 and the aldehydic group in M2 were found to be essential for the blend to be highly active at low doses. Both the bromoderivative of M1 and the 2,4-dinitrophenyl hydrazone of M2 retained >50% activity of the parent compounds.
