*[A bait, Amdro, containing the toxicant AC217,300 (tetrahydro-5,5-dimethyl-2(1-H)-pyrimidinone[3-[4-(trifluoromethyl)phenyl]-1[2-[4-(trifluoromethyl)phenyl]ethyl]-2-propenylidene]hydrazone), was tested for efficacy against the red imported fire ant, Solenopsis invicta Buren, in a pasture in southeastern North Carolina. Significant differences in fire ant colony activity & structure were found between treatment & control populations following broadcast (1.7 kg [AI]/ha) & single mound (= 5 tablespoons per mound) applications. High numbers of incipient fire ant colonies were found in the treated areas of the pasture following the Amdro applications. Deleterious effects on nontarget ant species were not detected. Residues of Amdro were undetectable within 24 h of the broadcast application. Because of the rapid reoccupation of treated areas by incipient colonies, multiple applications of Amdro will be required to achieve long-term suppression of S. invicta populations.]
