Eclosion of larvae from clustered tick eggs (1, 5, 10, 15, 20, 25, 50, and ±1,000 eggs) of Rhipicephalus sanguineus (Rs), Rhipicephalus microplus (Rm), Amblyomma cajennense (Ac), and Dermacentor nitens (Dn) was investigated at 43, 75, and > 98% relative humidity (RH) and 25 °C. Susceptibility of eggs to dehydration varied among tick species (Rs < Rm < Ac and Dn) and the number of clustered eggs but even singularized eggs of all tested species matured, and larvae eclosed at RH > 98%. A minimum of 25 clustered eggs and relative humidity close to saturation is suggested for quantitative tests on ovicidal activity of acaricides for related tick species.
在相对湿度为43%、75%和>98%以及25℃的条件下，对血红扇头蜱（Rs）、微小扇头蜱（Rm）、卡延钝缘蜱（Ac）和微小牛蜱（Dn）的聚集蜱卵（1、5、10、15、20、25、50以及±1000枚卵）的孵化情况进行了研究。卵对脱水的敏感性在蜱种之间（Rs < Rm < Ac和Dn）以及聚集卵的数量之间存在差异，但所有受试种类的单个卵即使经过处理也能成熟，并且在相对湿度>98%时幼虫孵化。对于相关蜱种杀螨剂杀卵活性的定量测试，建议至少使用25枚聚集卵且相对湿度接近饱和。
