Ten dogs were fitted with 10% propoxur-(0-isopropoxyphenyl methylcarbamate) and 10 dogs were fitted with 16% carbaryl-(1-naphthyl-N-methylcarbamate) impregnated flea collars. Ten cats were fitted with carbaryl-impregnated flea collars. There were 5 control animal for each trial. Insecticidal activity against experimental infestations with the cat flea (Ctenocephalides felis) was evaluated. The propoxur collars on dogs reduced the flea populations by 90% within 2 days of infestation for at least 13 weeks. By the 16th week, the flea population was reduced 65% in 2 days and 87% in 7 days. In subsequent infestations, efficiency was less than 80% after 7 days. Carbaryl collars on dogs reduced the flea population by as much as 80% in 2 days for a period of 16 weeks. An efficiency of at least 80% at 7 days was maintaned for 17 weeks. Carbaryl collars on cats reduced the flea population within 2 days by 80% or more for a period of at least 19 weeks--the last experimental infestation.
给10只狗佩戴了含10%残杀威（邻异丙氧基苯基甲基氨基甲酸酯）的项圈，给另外10只狗佩戴了含16%西维因（1-萘基-N-甲基氨基甲酸酯）的灭蚤项圈。给10只猫佩戴了含西维因的灭蚤项圈。每次试验设置5只对照动物。评估了对猫蚤（猫栉首蚤）实验性感染的杀虫活性。给狗佩戴的残杀威项圈在感染后2天内可使跳蚤数量减少90%，并至少持续13周。到第16周时，感染后2天跳蚤数量减少65%，7天减少87%。在随后的感染中，7天后效率低于80%。给狗佩戴的西维因项圈在16周内可在2天内使跳蚤数量减少多达80%。在7天时至少80%的效率维持了17周。给猫佩戴的西维因项圈在至少19周（最后一次实验性感染）内可在2天内使跳蚤数量减少80%或更多。
