Experimental tick infestations on dogs were done to determine the initial kill and residual effectiveness of a 15% fospirate-treated plastic colar against the brown dog tick, Rhipicephalus sanguineus (Latreille). The mean initial kill, determined 4 days after collar application (day 4), was 56.4%. The mean residual effectiveness of fospirate collars on test days 18, 33, 45, 61, 74, 88, and 112 was 89.1, 77.4, 89.5, 78.6, 73.2, 69.0, and 55.0% control, respectively.
对狗进行了实验性蜱虫感染,以确定用15% 丰索磷处理的塑料项圈对棕狗蜱(血红扇头蜱,拉特雷尔)的初始杀灭效果和残留效果。在项圈佩戴后4天(第4天)测定的平均初始杀灭率为56.4%。在第18、33、45、61、74、88和112天测试时,丰索磷项圈的平均残留效果分别为89.1%、77.4%、89.5%、78.6%、73.2%、69.0%和55.0%的控制率。
