The biocidal efficacy of entompathogenic nematodes against engorged females of Boophilus annulatus (Say) was evaluated in soil-filled buckets in a greenhouse, where conditions resemble nature. The 9 tested nematode strains differed markedly in their effect upon tick mortality. The Mexican strain of Steinernema carpocapsae was most efficient, inducing 100% tick mortality at a concentration of 50 nematodes per square centimeter. An increase in the concentration of the S. carpocapsae DT strain to > 200 IJ/cm2 failed to kill more ticks. It appears that entomopathogenic nematodes show promise as tick control agents.
在温室中装满土壤的桶里评估了昆虫病原线虫对饱血的环形牛蜱（Say）雌蜱的杀蜱效果，温室中的条件类似自然环境。所测试的9种线虫菌株对蜱死亡率的影响差异显著。墨西哥小卷蛾斯氏线虫菌株最为有效，在每平方厘米50条线虫的浓度下可导致100%的蜱死亡。将小卷蛾斯氏线虫DT菌株的浓度提高到>200条感染性幼虫/平方厘米并不能杀死更多的蜱。看来昆虫病原线虫有望成为蜱的控制剂。
