An electric walk-through fly trap was evaluated for the management of the horn fly, Hematobia irritans (L.), on dairy cattle in North Carolina over 2 yr. The trap relies on black lights and electrocution grids to attract and kill flies that are brushed from the cattle passing through. During the first season, horn fly densities were reduced from >1,400 to <200 flies per animal. Horn fly density averaged 269.2 +/- 25.8 on cattle using the walk-through fly trap twice daily, and 400.2 +/- 43.5 on the control group during the first year. The second year, seasonal mean horn fly density was 177.3 +/- 10.8 on cattle using the walk-through fly trap compared with 321.1 +/- 15.8 on the control group. No insecticides were used to control horn flies during this 2-yr study.
在北卡罗来纳州，对一种电动通道式捕蝇器进行了为期两年的评估，以用于管理奶牛身上的角蝇（Hematobia irritans (L.)）。该捕蝇器依靠黑光灯和电击网来吸引并杀死从经过的牛身上刷落的苍蝇。在第一季，每头牛身上的角蝇密度从超过1400只降至不到200只。在第一年，每天使用两次通道式捕蝇器的牛身上，角蝇密度平均为269.2±25.8只，而对照组为400.2±43.5只。第二年，使用通道式捕蝇器的牛身上，季节性平均角蝇密度为177.3±10.8只，而对照组为321.1±15.8只。在这项为期两年的研究中，未使用杀虫剂来控制角蝇。
