Over the dosage range from 0.02 to 1.0% boric acid, LC50s (95% CL) ranged from 1.27% (1.05-3.88%) at 3 d to 0.11% (0.09-13%) at 8 d. Amount of bait consumed was related inversely to the concentration of active ingredient. High concentrations of boric acid bait (5%) were consumed at a lower rate than the control (10% sucrose water). In large fire ant colonies exposed continuously to 4 concentrations (0.25, 0.5, 0.75, 1.0%) of boric acid bait, workers and brood were reduced by 90% at 6 wk. Therefore, low concentrations of boric acid are necessary for delayed toxicity and reduced repellency.1 aKlotz, J H1 aVail, K M1 aWilliams, D F  uhttps://antkey.myspecies.info/th/node/3345001500nas a2200145   4500008004100000245011800041210006900159260000900228300001200237490000700249520101800256100001801274700001401292856004801306       1994                        eng d00aControl of a natural infestation of the pharaoh ant (Hymenoptera: Formicidae) with a corn grit bait of fenoxycarb0 aControl of a natural infestation of the pharaoh ant Hymenoptera   cFeb.  a108-1150 v873 aThe insect growth regulator fenoxycarb was very effective against a natural infestation of the Pharaoh ant, Monomorium pharaonis (L.). A large building (7,841 m2) containing four separate wings was used to evaluate two concentrations of fenoxycarb (0.5 and 1%) in oil on a corn grit bait. Raid Max Ant Bait was used as a standard for comparative purposes. A separate wing was used for each treatment. One wing received no bait and functioned as a control. Our study demonstrated that 0.5% fenoxycarb in peanut butter oil was more effective than a 1% fenoxycarb bait and Raid Max Ant Bait; this treatment completely eliminated the ants < 6 wk after treatment. Reinfestation in the 0.5% fenoxycarb-treated wing occurred 24 wk after treatment and only at two sites in the area treated. Although Raid Max eliminated the ants < 6 wk after treatment, reinfestation occurred at 12 and 14 wk after treatment. Raid Max baits were applied again at 12 and 14 wk; no ants were detected in this wing after the 14-wk treatment.1 aWilliams, D F1 aVail, K M  uhttps://antkey.myspecies.info/th/node/3343801538nas a2200145   4500008004100000245017100041210006900212300001400281490000700295520099000302100001901292700001601311700001701327856004801344       1984                        eng d00aEffects of Amdro on the red imported fire ant (Hymenoptera: Formicidae) and some nontarget ant species and persistence of Amdro on a pasture habitat in North Carolina0 aEffects of Amdro on the red imported fire ant Hymenoptera Formic  a1012-10180 v773 a*[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.]1 aApperson, C.S.1 aLeidy, R.B.1 aPowell, E.E.  uhttps://antkey.myspecies.info/th/node/3342702285nas a2200181   4500008004100000022001300041245013300054210006900187260001600256300001400272490000800286520154800294100002001842700001701862700002201879700002301901856017901924       2014                        eng d  a0022049300aPheromone-Assisted Techniques to Improve the Efficacy of Insecticide Sprays Against Linepithema humile (Hymenoptera: Formicidae)0 aPheromoneAssisted Techniques to Improve the Efficacy of Insectic  cJan-02-2014  a319 - 3250 v1073 a<p>Outdoor residual sprays are among the most common methods for targeting pestiferous ants in urban pest management programs. If impervious surfaces such as concrete are treated with these insecticides, the active ingredients can be washed from the surface by rain or irrigation. As a result, residual sprays with fipronil and pyrethroids are found in urban waterways and aquatic sediments. Given the amount of insecticides applied to urban settings for ant control and their possible impact on urban waterways, the development of alternative strategies is critical to decrease the overall amounts of insecticides applied, while still achieving effective control of target ant species. Herein we report a &ldquo;pheromone-assisted technique&rdquo; as an economically viable approach to maximize the efficacy of conventional sprays targeting the Argentine ant. By applying insecticide sprays supplemented with an attractive pheromone compound, (Z)-9-hexadecenal, Argentine ants were diverted from nearby trails and nest entrances and subsequently exposed to insecticide residues. Laboratory experiments with fipronil and bifenthrin sprays indicated that the overall kill of the insecticides on Argentine ant colonies was significantly improved (57‐142% increase) by incorporating (Z)-9-hexadecenal in the insecticide sprays. This technique, once it is successfully implemented in practical pest management programs, has the potential of providing maximum control efficacy with reduced amount of insecticides applied in the environment.</p>
