Males of the hermit crab Pagurus filholi perform assessment behavior toward females, as a preliminary step of precopulatory guarding, during the reproductive season. It is known that such behavior is elicited by female sex pheromones, but the compounds involved have never been characterized in this species. Several experiments were conducted to develop a reliable bioassay along with purification procedures to identify potential compounds with pheromonal activity in Pagurus filholi.

更正：寄居蟹 Pagurus filholi 雌性信息素的行为分析和化学特征

寄居蟹 Pagurus filholi 的雄性寄居蟹会在繁殖季节对雌性进行评估行为，作为交配前保护的初步步骤。众所周知，这种行为是由雌性性信息素引起的，但所涉及的化合物从未在该物种中得到表征。进行了多项实验以开发可靠的生物测定以及纯化程序，以鉴定在 Pagurus filholi 中具有信息素活性的潜在化合物。
