Abstract

Borate products varied in efficacy against larval cat fleas, Ctenocephalides felis felis Bouché, with some effective at rates of 23 micrograms/cm2 when larvae were exposed to the compounds in sand. Powdered boric acid, granular boric acid, and disodium octaborate tetrahydrate (Polybor) at rates of 200 micrograms/cm2 produced < or = 90% mortality of larvae exposed in carpet for 96 h. LC50 values of larvae exposed in treated carpets for 96 h were 23 micrograms/cm2 for powdered boric acid, 40 micrograms/cm2 for granular boric acid, and 47 micrograms/cm2 for polybor.

摘要

硼酸盐产品对猫栉首蚤幼虫（Ctenocephalides felis felis Bouché）的防治效果各不相同，当幼虫在沙子中接触这些化合物时，有些产品在23微克/平方厘米的剂量下有效。以200微克/平方厘米的剂量使用硼酸粉末、硼酸颗粒和四水八硼酸钠（Polybor），在地毯上暴露96小时的幼虫死亡率≤90%。在经过处理的地毯上暴露96小时的幼虫，硼酸粉末的LC50值为23微克/平方厘米，硼酸颗粒为40微克/平方厘米，Polybor为47微克/平方厘米。
