Abstract
Two compounds at approx. molecular weights 400 and 800 were tested over 4 yrs. on cattle by both "half-cow" and whole cow methods in New Jersey and in Florida. These materials at 10% concns. in oil or emulsified in water are repellents for Stomoxys calcitrans and Siphona irritans. Preliminary field tests on horses indicate that they are also repellent to Tabanus spp. These materials also possess very low toxicity to mammals, are not irritating, are synergists for pyrethrum and can be formulated readily in oil or water.Keywords
