Comparison of biodegradable, plastic and wooden imidacloprid-treated spheres for control of Rhagoletis mendax (Diptera: Tephritidae) flies
Florida Entomologist 86 (2), 206-210
Abstract: In experiments comparing biodegradable, plastic and wooden imidacloprid-treated spheres for control of Rhagoletis mendax Curran, the mean number of flies caught on plexiglas panes below each sphere type was not significantly different for the entire season. However, the mean time spent by R. mendax flies alighting on biodegradable imidacloprid-treated spheres was significantly greater (2.6×) than plastic imidacloprid-treated spheres. During 2001, significantly fewer larvae were found in blueberries harvested from bushes that had wooden imidacloprid-treated spheres hung within the canopy compared with bushes where biodegradable and plastic imidacloprid-treated spheres were deployed. There was no significant difference between the number of larvae found in berries picked from bushes where biodegradable or plastic spheres were deployed. All imidacloprid-treated sphere treatments were found to significantly reduce blueberry maggot larval infestation in fruit compared with the control.

En experimentos comparando las esferas de plástico y de madera biodegradable y tratadas con imidacloprid para el control de Rhagoletis mendax Curran, el promedio del número de las moscas atrapadas sobre la superficie de "plexiglas" debajo cada clase de esfera no fué significativamente diferente para la estación completa. No obstante, el promedio del tiempo pasado por mosca de R. mendax encima de las esferas biogradables tratadas con imidacloprid fué significativamente mayor (2.6 veces) que en las esferas plasticas tratadas con imidacloprid. Durante 2001 , fueron significativamente encontradas menos larvas sobre las moras (Vaccinium sp.) cosechadas de arbustos que tenian las esferas de madera tratadas con imidacloprid colgadas dentro del dosel comparados con arbustos donde pusieron esferas de plástico biodegradable y tratadas con imidacloprid. No habia una diferencia significativa entre el número de larvas encontradas en la frutas cortadas de los arbustos donde habian puestas las esferas de plástico biodegradable y tratadas con imidacloprid. Se encontraron que todos los tratamientos de las esferas tratadas con imidacloprid redujieron significativamente la infestación de larvas en las frutas comparados con el control.
