Abstract
The mortality of first-stage larvae of the house fly, Musca domestica L., seeded into the manure of dairy cows consuming 0.144 ppm coumaphos in their ration increased as the concentration of coumaphos in the ration was increased. At the 144 ppm level, larval mortality approached 100%. Although coumaphos residues were found in the feces no residues 0.002 ppm) appeared in the milk of cows at any level of coumaphos fed. Neither feed intake nor milk production was affected by the feeding of coumaphos. The blood chokinesterase of 1 cow fed 150 ppm couma-phos. over a 6-week period dropped to 20% of pre-experi mental levels.
