A PVC ear tag containing the synthetic pyrethroid flucythrinate was tested in seventeen herds including 218 heifers. There was a comparable control group of twelve herds including 157 heifers. The ear tags were more effective against sucking flies than they were against sticking flies. Varying with the species of the fly, the effectiveness ranged from 36.2 per cent to 95.7 per cent. The effectiveness also varied between the herds. The active constituent was still released within approximately 5 1/2 months after introduction.
一种含有合成拟除虫菊酯氟氰菊酯的PVC耳标在17个牛群中进行了测试，其中包括218头小母牛。有一个由12个牛群组成的对照可比组，包括157头小母牛。耳标对吸血蝇的效果比对黏附蝇的效果更好。根据苍蝇的种类不同，效果范围在36.2%至95.7%之间。不同牛群之间的效果也有所不同。活性成分在引入后大约5个半月内仍在释放。
