Latest information from the NYS IPM Program
The first SWD of the year was trapped in Tioga county on June 26th. A single male was trapped in a drowning jar trap. The trap was located in a blueberry planting, and the fruit in the planting are beginning to blush.
Thank you to Gary Phelps for servicing these traps!
We reached sustained trap catch in Albany county today. That means that SWD was found in the trap both last week and this week, and is presumed to be present and breeding in the planting.
The traps were set in a raspberry planting, which is currently bearing ripe fruit. Both male and female SWD were trapped in the drowning jar and sticky traps. Thank you to Natasha Field for servicing those traps!
SWD is now showing up fairly regularly in traps in many of the counties in our monitoring network. Best management strategies were covered in a post last week.
Saratoga county had its first SWD of the season caught on June 23rd. A single male was trapped on a red sticky trap in a blackberry planting. Blackberries are not yet able to be fed on by SWD, but there were ripe raspberries nearby to the blackberry planting.
Remember to keep any ripening fruit covered if SWD has been caught in your county! If you would like to learn more about monitoring for SWD using the red sticky cards, contact me or review last year's post on the topic: https://blogs.cornell.edu/swd1/2022/02/08/red-sticky-card-traps-for-swd-monitoring/.
I'd like to give a big thank you to Natasha Field, ENYCHP, who was monitoring the trap in Saratoga county, as well as traps from the previous two posts!
We also reached sustained catch in Orange county on June 22nd. Three SWD were trapped in a cherry block, including 2 males on sticky traps and 1 female in a drowning jar trap.
First catch in Albany county on June 22, in a raspberry planting. A single SWD male was trapped in a drowning trap.
First catch in Dutchess county on June 22. Four total SWD were trapped between a cherry and raspberry planting.
Spotted wing drosophila was trapped in both a cherry and a raspberry block in Orleans Co this week. In the raspberry planting, 1 female SWD was trapped in a jar drowning trap. In the cherry block (there are both tart and sweet cherries in the block), 2 male SWD were trapped in a jar drowning trap. Both traps are on the same farm.
Cherries are coloring up, and SWD number can increase rapidly.

Laura McDermott, ENYCHP found 1 male SWD in Amelanchier (Juneberries) on a red sticky trap. Females are too difficult to identify on the sticky traps, so only males are quantified in that trap type. The trap was checked on June 15th 2022.
Rensselaer county is the seventh county in the state to catch a SWD this year.
Numbers remain very low in all counties (although creeping up in Orange Co), but stay on the alert!
A single female SWD was caught in a jar drowning trap in Schuyler county yesterday June 14th 2022. This trap is in a blueberry planting, which is being monitored by Anya Osatuke, Harvest NY.
Most blueberry fruits in the area are still hard and green, not yet susceptible to SWD infestation.
This week we trapped the first SWD for 2022 in Orange county. A total of 5 SWD (4 male and 1 female) were trapped in both sticky and jar traps, in sweet and tart cherry blocks in Orange county, on June 13th. This indicates the highest population of SWD we've seen so far this year.
The traps are being monitored by Miles Todaro, ENYCHP.
We have now reached sustained trap catch in Columbia County.
Last week Natasha Field (ENYCHP) trapped a single male swd in a sweet cherry planting. This week she trapped an additional 1 male and 2 females in the same block, also in a Scentry jar drowning trap. Sweet cherries are beginning to blush, and fruit is likely to be susceptible.
Cherry growers in Columbia County should begin their spray program now, if they have not already.
