Curative activity contributes to control of spotted-wing drosophila (Diptera: Drosophilidae) and blueberry maggot (Diptera: Tephritidae) in highbush blueberry

چکیده
Semi-field experiments were used to compare the curative activity of insecticides on spotted-wing drosophila (Drosophila suzukii (Matsumura) (Diptera: Drosophilidae)) and blueberry maggot (Rhagoletis mendax Curran (Diptera: Tephritidae)) in blueberry fruit. The organophosphate phosmet, the spinosyn spinetoram, and neonicotinoids imidacloprid, acetamiprid, and thiamethoxam showed significant lethality on spotted-wing drosophila and blueberry maggot larvae and eggs, when applied topically to blueberry fruit post-infestation. The pyrethroids fenpropathrin and zeta-cypermethrin showed high levels of post-infestation activity on spotted-wing drosophila larvae or eggs, and indoxacarb showed statistically weaker activity. Curative activity is a previously unrecognised contributor to the overall means by which blueberry growers may achieve control of spotted-wing drosophila and blueberry maggot with the use of insecticides in blueberries.

A Review of the Blueberry Maggot Fly (Diptera: Tephritidae)
Native to North America, the blueberry maggot fly, Rhagoletis mendax Curran (Diptera: Tephritidae), has historically been considered one of the most important insect pests of commercially grown highbush and lowbush blueberries in many parts of the northeastern and north central United States and Canada. Larval infestation results in unmarketable berries owing to a zero-tolerance policy enforced...

First report of Zaprionus indianus (Diptera: Drosophilidae) in commercial fruits and vegetables in Pennsylvania.
Zaprionus indianus (Gupta) (Diptera: Drosophilidae), an invasive vinegar fly, was found for the first time in Adams County, Pennsylvania, in 2011. It was found in a commercial tart cherry orchard using apple cider vinegar (ACV) traps that were monitoring another invasive vinegar fly, the spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae). Coincidentally, the first ...
متن کاملAssociation and attraction of blueberry maggot fly Curran (Diptera: Tephritidae) to Pantoea (Enterobacter) agglomerans.
The attraction of washed, medium-free cells of Pantoea (Enterobacter) agglomerans to wild, adult Rhagoletis mendax Curran, the blueberry maggot fly, was evaluated in managed blueberry fields in Maine. Attraction was evaluated using Pherocon AM and Ladd traps, each tested with or without washed bacterial cells. Field studies showed significant increases in fly captures on the Pherocon AM traps. ...
