Fruit Flies in Connecticut: what the public record shows

Before you compare quotes, it helps to know which fruit flies actually live in Connecticut, when they are busiest, and what the state figures look like. Everything below links to the agency or university page it came from.

The Connecticut Agricultural Experiment Station states that SWD "was first detected in Connecticut in 2011 across 86 towns"

Statewide SWD detection in 2011

SWD is now established statewide, so Connecticut backyard raspberry and blueberry growers should expect infested fruit rather than treat it as an occasional event.

The Connecticut Agricultural Experiment Station

CAES notes that "Unlike most fruitflies, which have little or no impact on the fruit industry, SWD females possess a serrated ovipositor that allows them to lay eggs inside intact, ripening fruit," causing losses in berries and cherries "costing U.S. growers hundreds of millions of dollars each year"

Why SWD attacks sound fruit

It explains why Connecticut fruit brought indoors can already contain larvae, and why fruit should be refrigerated promptly rather than left on a counter.

The Connecticut Agricultural Experiment Station

UConn IPM reports SWD "arrived in Connecticut with a vengeance in the late summer of 2011," "forcing the end of fall raspberry harvest across the state," and that the first trap catch the following spring was "in early April of a single male SWD in southern CT"

The 2011 fall raspberry crop failure

Early-April activity means Connecticut monitoring has to begin well before fruit ripens, not at first damage.

When fruit flies are busiest in Connecticut

UConn IPM has caught SWD as early as the first week of April in southern Connecticut, with the damaging peak in late summer, when the 2011 invasion ended the fall raspberry harvest statewide.

UConn's IPM program ranks fall raspberries, blackberries, late blueberries, day-neutral strawberries and sweet cherries as highest risk and peaches, grapes and June strawberries as moderate risk. It advises starting monitoring early, erring "on the early side rather than later," using apple cider vinegar with soap or a yeast, sugar, water and whole wheat bread bait, and changing the bait weekly or more often as catch increases.
