Low-volume application of dichlorvos to dairy farms by fixed-wing aircraft resulted in decreases in the numbers of stable flies, Stomoxys calcitrans (L.), which ranged from 30 to 60% 24 hours posttreatment. Low-volume applications of naled by both helicopter and fixed-wing aircraft at feedlots resulted in decreases of stable fly numbers, which ranged from 77.9 to 92% and 30.8 to 94.3%, respectively, 24 hours posttreatment. Ultra-low-volume (ULV) applications at feedlots by fixed-wing aircraft of naled, fenthion, dichlorvos, and a mixture of dichlorvos and Shell SD-8447 (2-chloro-1-(2,4,5-trichlorophenyl) vinyl dimethyl phosphate) resulted in decreases in stable fly numbers, which averaged 78.4, 75.1, 85.8, and 75.9%, respectively, 24 hours posttreatment. ULV applications of fenthion, trichlorfon, malathion, and naled by fixed-wing aircraft resulted in a reduction of 90% or more in the numbers of horn flies on range cattle. Five aerial ULV applications of naled within 62 days were not enough to keep horn fly, Haematobia irritans (L.), numbers on range cattle below 50 per animal.
