ABSTRACT:
Male-produced aggregation pheromones were demonstrated in Carpophilus hemipterus (L.), Carpophilus lugubris Murray, and Carpophilus freemani Dobson (Coleoptera: Nitidulidae) using a wind-tunnel bioassay. The attractiveness of the pheromones is greatly enhanced by volatiles from a host plant, and combinations of pheromone and food volatiles typically attract 3-10 times more beetles than either source by itself. The pheromones consist of a series of 12-, 13-, 14-, and 15-carbon unsaturated hydrocarbons. The most abundant of these in C. hemipterus is (2E,4E,6E,8E)-3,5,7-trimethyl-2,4,6,8-decatetraene. In C. lugubris, the most abundant is (2E,4E,6E,8E)-7-ethyl-3,5-dimethyl-2,4,6,8-undecatetraene, and in C. freemani, (2E,4E,6E)-5-ethyl-3-methyl-2,4,6-nonatriene.
