Investigations of bark beetle pheromones have been concerned largely with the occurrence of these chemicals in virgin beetles. In many Scolytidae, the parent adults re-emerge from an initially attacked host tree after they have completed egg-gallery construction and oviposition in the tree. These parent adults may attack another tree and establish another brood. Very little is known about pheromone production and field attractiveness of such beetles.

南方松甲虫重新出现的亲本雌性中聚集信息素的产生

对树皮甲虫信息素的研究主要关注这些化学物质在原始甲虫中的出现。在许多 Scolytidae 中，父母成虫在完成卵廊构建和在树中产卵后从最初受到攻击的寄主树中重新出现。这些父母成虫可能会攻击另一棵树并建立另一个巢穴。人们对这种甲虫的信息素产生和田间吸引力知之甚少。
