The stable fly (Stomoxys calcitrans Linnaeus) was a serious insect pest of cattle. Both sexes sucked blood. The female laid eggs in masses of about 10 to 12 eggs. At 33-35C, the egg stage was 20-25 hours, the larval stage 7-10 days and the pupal stage 4-6 days. At 30-32C, the egg stage was 23-26 hours, the larval stage 14-18 days and the pupal stage 6-8 days. At 25-27C the egg stage was 26-30 hours, the larval stage 17-19 days and the pupal stage 7-9 days. Surveys of stable flies on cattle throughout a year showed that stable flies were most numerous in February and during the period of early Jun to the end of August. Studies of poison baits showed that fresh cattle blood mixed with dedevap 0.075 percent or baygon 0.03 percent gave good control of flies. Control of stable flies was also attempted by spraying 4 insecticides on cattle. Only three insecticides viz decis 0.00125 percent, baygon 0.125 percent and dedevap 0.125 percent, showed a good level of control of flies with a mortality of 93.3 percent, 83.3 percent and 50 percent, respectively, six hours after treatment.
