本研究利用一系列的体外试验在完善的试验区域并保持试验开始前P.绵羊未发病对潜在的杀螨药物抵抗绵羊痒螨的疗效进行评估。试验中，45种防治药物，包括精油、清洁剂、干燥剂、生长调节剂、脂质合成抑制剂、神经功能/能量代谢干扰物和蜕皮激素对成虫和幼虫的死亡率的影响进行了评估。

结果证实最有效的候选药物是干燥剂（硅藻土、粘土和??属），生长调节剂（噻嗪酮、噻螨酮、氟苯脲），脂质合成抑制剂（螺螨酯、螺虫乙酯和螺甲螨酯）以及神经功能和能量代谢抑制剂（霸螨灵、多杀菌素、唑虫酰胺、氯虫苯甲酰胺）。

Primary screen for potential sheep scab control agents

Abstract: The efficacy of potential acaricidal agents were assessed against the sheep scab mite Psoroptes ovis using a series of in vitro assays in modified test arenas designed initially to maintain P. ovis off-host. The mortality effects of 45 control agents, including essential oils, detergents, desiccants, growth regulators, lipid synthesis inhibitors, nerve action/energy metabolism disruptors and ecdysteroids were assessed against adults and nymphs. The most effective candidates were the desiccants (diatomaceous earth, nanoclay and sorex), the growth regulators (buprofezin, hexythiazox and teflubenzuron), the lipid synthesis inhibitors (spirodiclofen, spirotetramat and spiromesifen) and the nerve action and energy metabolism inhibitors (fenpyroximate, spinosad, tolfenpyrad, and chlorantraniliprole).
