- Abstract
The activity of the insecticide thiamethoxam on populations of Musca domestica was assessed through in vitro tests, controlled environment and field conditions. The flies were gathered from a colony maintained by the Laboratory of Parasitic Diseases, Department of Epidemiology and Public Health, Universidade Federal Rural do Rio de Janeiro, and from the landfill of the city of Seropédica-RJ, Brazil. Regarding the in vitro assay, thiamethoxan was previously diluted in acetone, resulting in concentrations of 5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25, 27, 5 and 30 mg/ml. Then, filter paper discs were impregnated with 1 ml of each of these dilutions. Thus, the test was conducted with adult flies maintained in Petri dishes. For the controlled environment and field conditions, trial baits were used with the active or a placebo (control group). The lethal concentration 50 (LC50) of thiamethoxam on M. domestica found in the in vitro assay was 0.2612 mg / cm2. The efficacy of thiamethoxan baits on the controlled environment and field conditions trials was 94.06 % and 98.09 %, respectively.
