چکیده
Baited pesticide-treated biodegradable spheres were evaluated for their efÞcacy to control and monitor apple maggot, Rhagoletis pomonella (Walsh), and blueberry maggot, R. mendax Curran, ßies. A Plexiglas pane treated with sprayable Tangle-Trap was found to be an effective technique for assessing the fate of Rhagoletis ßies encountering treated spheres. SigniÞcantly more R. pomonella and R. mendax ßies were captured on Plexiglas panes below pesticide-treated spheres comparedwithpanesbelownonpesticide-treated spheres. Themean time spent onpesticide-treated spheres was also signiÞcantly longer compared with nonpesticide-treated spheres. Monitoring traps (consisting of unbaited 9-cm-diameter red sticky spheres) placed within a 2-m radius of pesticidetreated spheres captured signiÞcantly fewer ßies compared with traps placed at the same distance from nonpesticide-treated spheres. The results support the potential for using pesticide-treated spheres for control of R. pomonella and other Rhagoletis species.

متن کاملEffect of Surround WP on behavior and mortality of apple maggot (Diptera: Tephritidae).
Apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), is a key pest in apple (Malus spp.) production areas located in the northeastern and midwestern United States and the eastern provinces of Canada. The development of Surround WP has offered a new approach for controlling apple maggot and other tephritid species, because this material is considered to be compatible with advanced ...
متن کاملComparison of neonicotinoid insecticides for use with biodegradable and wooden spheres for control of key Rhagoletis species (Diptera: Tephritidae).
Field-based studies and laboratory bioassays were conducted with apple maggot, Rhagoletis pomonella (Walsh), and blueberry maggot, Rhgoletis mendax Curran, flies to investigate the performance and duration of activity of insecticide-treated biodegradable and wooden spheres for control of Rhagoletis species. Four neonicotinoid insecticide treatments including imidacloprid, thiamethoxam, and thio...
متن کاملEvaluation of various deployment strategies of imidacloprid-treated spheres in highbush blueberries for control of Rhagoletis mendax (Diptera: Tephritidae).
Biodegradable, ammonium-baited spheres treated with the neonicotinoid insecticide Provado (imidacloprid) at 2% (AI) were evaluated for controlling blueberry maggot flies, Rhagoletis mendax Curran. Three strategies for sphere deployment in highbush blueberries, Vaccinium corymbosum L., were compared with untreated control plots in 1999 and once again compared against control plots and organophos...

Two insecticide formulations containing the naturalyte insecticide spinosad, GF-120 Fruit Fly Bait and SpinTor 2 SC, were compared for control of apple maggot, Rhagoletis pomonella (Walsh), and blueberry maggot, Rhagoletis mendax Curran. In 2002 and 2003, larval infestation in blueberries and apples was signiÞcantly lower in plots treatedwithGF-120 (spinosad bait) or SpinTor than in untreated c...
