Entomopathogenous nematodes are well known biocontrol agents of insects. They live in the superficial layer of the soil, a location where ticks accomplish their molt and where they oviposit their eggs, making them, theoretically, the preys of infective larvae of nematodes. Seventeen strains of entomopathogenous nematodes: eight strains of Steinernema and nine strains of Heterorhabditis were placed in contact with each of the free living stages of three tick species: Amblyomma variegatum, Boophilus microplus and B. annulatus. The first two species were resistant to all the nematode strains that were tested, whereas B. annulatus was susceptible to all of them. Ovipositing females were more susceptible than females during the preoviposition period. There were no anatomical differences between the two species of Boophilus which can account for such differences in their susceptibility. The use of nematodes to control some species of ticks should be considered.
昆虫病原线虫是著名的昆虫生物防治剂。它们生活在土壤表层，而蜱虫在该位置进行蜕皮和产卵，从理论上讲，这使蜱虫成为线虫感染性幼虫的猎物。将17株昆虫病原线虫（8株斯氏线虫属和9株异小杆线虫属）与三种蜱虫（变异革蜱、微小牛蜱和环形牛蜱）的每个自由生活阶段接触。前两个物种对所有测试的线虫菌株均具有抗性，而环形牛蜱对所有菌株均敏感。产卵雌蜱比产卵前期的雌蜱更易受感染。微小牛蜱的两个物种之间在解剖学上没有差异，无法解释它们易感性的差异。应考虑使用线虫来控制某些蜱虫物种。
