The insect growth regulators (IGRs), Stauffer R-20458, (E) -6,7-epoxy-l- (p-ethylphenoxy) -3,7-dimethyl-2-octene; Thompson-Hayward TH-6040, N-,4-chlorophenyl-N′- (2,5- difluorobenzoyl) urea; methoprene: 2,3-epoxy-9- (p-ethyl-phenyl) -2,6-dimethylnonane; 2-ethoxy-9- (p-ethylphenyl). 2,6-dimethyl-nonane; 2-ethoxy-9- (p-isopropylphenyl) -2,6- dimethylnonane, and chlorpyrifos, iodophenfos, stirofos, ronnel, stirofos plus dichlorvos and, a bacterial agent, Subdu®, Bacillus thuringiensis Berliner plus B. subtilis (Cohn) were evaluated as surface sprays on breeding areas in Nebraska cattle feedlots for activity against Stomoxys calcitrans (L.). The IGRs were as effective as the insecticides at the levels tested in inhibiting adult emergence from the breeding areas. A period of 7 days or more was necessary before effects of the treatments could be determined.
