SWD in plums

I have begun examining plums collected in the Finger Lakes and Lake Ontario regions and, to date, have found evidence of oviposition only in samples collected in the Finger Lakes region. As populations of SWD build during late summer and plums ripen on the tree, fruit may be at increasing risk. Which plum varieties are […]

Steuben County – first report

Probable SWD larvae have been found in ripe/overripe blueberry fruit by Stephanie Mehlenbacher, Steuben County Cornell Cooperative Extension. Although it is not possible to definitively identify SWD from its larval stage, the size and characteristics strongly point to SWD. Infested blueberry fruit will have tiny pinholes from which liquid will leak out of the berry; […]

Black cherry hosts SWD

The forest and woodland tree, black cherry, Prunus serotina, is another SWD-preferred wild host. This tree grows in forests and landscapes throughout the Northeast and is native to North America. On Long Island, recent inspections by Faruque Zaman, Suffolk County Cornell Cooperative Extension, showed that over 90% of its fruit were infested with SWD. On […]

Monroe County – first report

A single male SWD was reared from black raspberry fruit collected from a farm in Monroe County on July 22, 2013 by Debbie Breth, Lake Ontario Fruit Program, Cornell Cooperative Extension. Traps collected this week are currently being processed, though traps set at this farm location have not yet caught SWD. Raspberries are very susceptible […]

Erie County – first report

A single female SWD was caught in a trap in Erie County by Sharon Bachman, Erie County Cornell Cooperative Extension, and confirmed by me, Juliet Carroll, NYS IPM Program. The trap was set near brambles. SWD is being consistently caught in traps in many locations in NY underlining the need to establish insecticide programs to […]

Two male and one female SWD were caught in one out of four traps collected by yours truly on July 30 from a sweet cherry orchard in Orleans County. Traps near a raspberry high tunnel and in a blueberry plantation on the same farm did not have SWD in them. (Accumulated GDD 1475; day length […]
