The activities of three avermectins and deltamethrin as oviposition suppressants were investigated with a laboratory bioassay in which gravid females of the blowfly Lucilia cuprina (Wiedemann) were exposed to treated oviposition targets. An easily comparable index of suppression, the oviposition suppression concentration (OSC), was defined. All four compounds were effective oviposition suppressants. The three avermectins had similar OSC50 values (approximately 13 ppm). Deltamethrin, with an OSC50 of 0.4 ppm, was the most potent suppressant. The avermectins all produced significant mortality in adults with suppressed oviposition, while deltamethrin did not cause an increase in deaths at concentrations giving up to 100% suppression of oviposition. The toxicities of all four compounds to adult females were similar when assessed by topical application.
采用实验室生物测定法，研究了三种阿维菌素和溴氰菊酯作为产卵抑制剂的活性。在该测定法中，将铜绿蝇（Wiedemann）的妊娠雌蝇暴露于经过处理的产卵目标物上。定义了一个易于比较的抑制指数，即产卵抑制浓度（OSC）。所有四种化合物都是有效的产卵抑制剂。三种阿维菌素的OSC50值相似（约13 ppm）。溴氰菊酯的OSC50为0.4 ppm，是最有效的抑制剂。阿维菌素在产卵受到抑制的成虫中均产生了显著的死亡率，而溴氰菊酯在达到100%产卵抑制的浓度下并未导致死亡增加。通过局部应用评估时，所有四种化合物对成年雌蝇的毒性相似。
