The presence of a pre-feeding aggregation pheromone was demonstrated in the species Dermacentor variabilis, Dermacentor andersoni, Dermacentor parumapertus, Amblyomma americanum and Haemaphysalis leporispalustris by assay within a petri dish. However, Amblyomma maculatum and Amblyomma cajennense did not aggregate in the sector containing discs of presumed pheromone within the hour period. D. andersoni and A. americanum recognized each other's pheromone and A. americanum recognized that of H. leporispalustris. Preliminary experiments with guanine and hemin as possible aggregating factors have thus far given inconsistent results.
通过在培养皿中进行测定，已证明变异革蜱、安氏革蜱、微小革蜱、美洲钝缘蜱和沼泽兔血蜱等物种中存在进食前聚集信息素。然而，斑点钝缘蜱和卡延钝缘蜱在一小时内未在含有假定信息素圆盘的区域聚集。安氏革蜱和美洲钝缘蜱能识别彼此的信息素，美洲钝缘蜱能识别沼泽兔血蜱的信息素。迄今为止，以鸟嘌呤和血红素作为可能的聚集因子进行的初步实验结果并不一致。
