In the last decade or so most home orchardists have learned to loathe the Spotted Wing Drosophila fly, or more specifically the small white larva that turn up in cherries, raspberries and other soft fruit. This jar type trap with the Broad Spectrum Lure is a key component of an integrated pest management strategy. In other words, larger growers use them to monitor the SWD population so they can tell whether or when to apply chemicals. In a backyard setting though, 1 or 2 traps can be surprisingly effective to actually control this pest. Like all pheromone traps it operates on the basis of attracting and retaining the males and thereby disrupting the mating pattern. The lures are designed to hang from the inside of the trap jar lid. It is suggested to put about an inch of water with a drop of unscented soap in the bottom of the jar to drown the captured male flies.
The traps should be positioned in a shady spot close to the fruit well before it begins to ripen. For tree fruit such as cherries or plums they can be hung on a low branch. For blueberries or canefruit the traps are generally attached to a stake, or trellis wire right in the canopy of the bush if possible. The kit contains 1 trap, 1 set of Broad Spectrum replaceable lures and detailed instructions.
