Controlled tests of the efficacy of bot-active compounds, dichlorvos, trichlorfon, trichlorfon butonate, and carbon disulfide on the larvae of Gasterophilus intestinalis and Gasterophilus nasalis during their migratory period in the tissue of the mouth of horses and ponies were completed on experimentally induced and naturally acquired infections. Against the experimental parasitisms in pony foals, the resin-pellet formulation of dichlorvos given on the feed at the dose level of 37 mg/kg, 2 formulations of trichlorfon given by stomach tube at the dose level of 40 mg/kg, another of trichlorfon given on the feed, and trichlorfon butonate given intragastrically at the dose level of 43 mg/kg were 100% efficacious. Against naturally acquired parasitisms in horses, a broad-spectrum gel formulation of dichlorvos given intraorally at the dose level of 36 mg/kg was quite efficacious, whereas liquid carbon disulfide given by stomach tube at the dose level of 2.4 ml/45.45 kg was ineffective.
在实验诱导感染和自然感染的情况下，完成了对活性化合物敌敌畏、敌百虫、丁硫敌百虫和二硫化碳对马胃蝇和鼻胃蝇幼虫在马和小马口腔组织迁移期的疗效对照试验。对于小马驹的实验性寄生虫感染，以37毫克/千克的剂量水平通过饲料投喂的敌敌畏树脂颗粒制剂、以40毫克/千克的剂量水平通过胃管投喂的两种敌百虫制剂、另一种通过饲料投喂的敌百虫制剂以及以43毫克/千克的剂量水平经胃内给药的丁硫敌百虫，疗效均达100%。对于马的自然感染寄生虫，以36毫克/千克的剂量水平经口投喂的敌敌畏广谱凝胶制剂疗效显著，而以2.4毫升/45.45千克的剂量水平通过胃管投喂的液体二硫化碳则无效。
