Juvenile Hormone Mimics as Feed Additives for Control of the Face Fly and House Fly
Three juvenile hormone mimics, methoprene (as Altosid®); (E)-4-[(6, 7-epoxy-3, 7-dimethyl-2-nonenyl)oxy]-1, 2-(methylenedioxy)benzene (as Hoffman-La Roche Ro 20-3600); and (E)-6, 7-epoxy-1-(p-ethylphenoxy)-3, 7-dimethyl-2-octene (as Stauffer R-20458) were mixed with fresh cow manure and seeded with larvae of the house fly, Musca domestica L., and the face fly, Musca autumnalis De Geer. Methoprene at 1 ppm completely inhibited development of face flies, and at 10 ppm markedly inhibited the development of house flies. Ro 20-3600 at 10 ppm inhibited the development of face flies but had no effect on house flies, even at 100 ppm. R-20458 at 100 ppm had no effect on face flies or house flies.
Also, methoprene fed to cattle at a rate of 1 mg/kg body weight gave essentially complete control of face flies, and a rate of 2.5 mg/kg body weight gave significant control of house flies. Ro 20-3600 fed at a rate of 10 mg/kg body weight gave complete control of face flies but had no effect on house flies.
