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.
使用风洞生物测定法,在黑斑木蠹(Carpophilus hemipterus (L.))、哀怨木蠹(Carpophilus lugubris Murray)和弗里曼木蠹(Carpophilus freemani Dobson)中证明了雄性分泌的聚集信息素。这些信息素的吸引力受到寄主植物挥发物的极大增强,信息素和食物挥发物的组合通常比单独使用任一来源吸引3-10倍的甲虫。这些信息素由一系列12、13、14和15碳不饱和烃组成。在黑斑木蠹中,最丰富的是(2E,4E,6E,8E)-3,5,7-三甲基-2,4,6,8-十碳四烯。在哀怨木蠹中,最丰富的是(2E,4E,6E,8E)-7-乙基-3,5-二甲基-2,4,6,8-十一碳四烯,而在弗里曼木蠹中则是(2E,4E,6E)-5-乙基-3-甲基-2,4,6-非三烯。
