L. aSlow-release devices for livestock insect controlbcattle body surfaces contacted by five types of devices. c1977 aPads containing a visible dye in an oil solution were attached to a neck band, a halter, a tail tag, ear tags, and leg bands to simulate slow-release insecticide devices. The devices were placed on cows held individually in outside pens exposed to a population of 50-200 horn flies, Haematobia irritans (L.). Selfgrooming and movements to combat the flies caused dye transfer from the devices to limited areas on the cows. Photographs were taken 24 h after the devices were placed on the cows to record the pattern of dye transfer from each device. A slow-release device must be matched to the habits of the target pest so insecticide released by such a device will be applied to preferred feeding or resting sites on the host. acattle aGado aHaematobia Irritans aInseto aControl aControle aHorne fly aInsect aMosca do chifre1 aGINGRICH, A.
