Horn fly, Haematobia irritans (L.), populations were controlled on yearling cattle (n = 246) during the grazing season at moderate levels (68% control) with the use of organophosphate- and pyrethroid-impregnated ear tags. Weight gains of treated cattle during the 3-yr period were 17% greater than for untreated cattle. Results from this study demonstrated that yearling cattle of 25 or 50% Brahman, Bos indicus, breeding responded with improved animal performance in Louisiana when moderate horn fly control was achieved.
在放牧季节，使用有机磷酸酯和拟除虫菊酯浸渍的耳标，对一岁牛（n = 246）身上的角蝇（Haematobia irritans (L.)）种群进行了适度控制（68%的控制率）。在这3年期间，经处理的牛的体重增加比未处理的牛高17%。这项研究的结果表明，在路易斯安那州，当角蝇得到适度控制时，具有25%或50%婆罗门牛（Bos indicus）血统的一岁牛的生长性能得到了改善。
