Laboratory Evaluation of Baits, Residual Insecticides, and an Ultrasonic Device For Control of White-Footed Ants, Technomyrmex albipes (Hymenoptera: Formicidae)

摘要

Experimental and commercial baits, gels, residuals, one insecticidal dust, and an ultrasonic pest repeller were compared in laboratory tests for control efficacy against containerized sub-colonies of white-footed ants, Technomyrmex albipes. NecDew~(TM), an experimental bait with 10 ppm thiamethoxam, reached 62% mortality at 8 days, and 100% mortality at 35 days, and would therefore likely achieve an acceptable level of control in the field. Other baits yielding high mortality were imidacloprid in 25%(w/v) sucrose water, NecDew~(TM) with 10,000 ppm DOT, 10 ppm thiamethoxam in 25% (w/v) sucrose water, and Terro Ant Killer II. Results from the other baits, residuals, gels, insecticidal dust, and the ultrasonic pest repeller were all unsatisfactory.Implications for field efficacy against white-footed ants are discussed.
