Spotted Wing Drosophila, Brown Marmorated Stink Bugs Nagging Fruit Growers

In a Penn State University Extension bulletin, Grzegorz Krawczyk, Extension Tree Fruit Entomologist indicated brown marmorated stink bug (BMSB) nymphs are present in orchards. He says the pest is now a “resident” pest as opposed to a “migratory” pest.

Krawczyk recommends using lures to detect and capture BMSB adults and nymphs.

He offers recommendations for growers on control of other pests such as Oriental fruit moth, tufted apple bud moth, obliquebanded leafroller, codling moth, apple maggot, aphids, leafhoppers, and leafminers.

Michigan
In a Michigan State University extension bulletin, Rufus Isaacs and Juliana Wilson of Michigan State University Extension, Department of Entomology, noted that the first activity of spotted wing drosophila (SWD) for the year was recorded in a monitoring trap in Southwestern Michigan last week.

“This timing of first capture is a few weeks later than 2012 and 2013, suggesting that the harsh winter slowed down the spring development of SWD. However, at some of the sites where SWD were trapped, the flies are somewhat more abundant than first captures in previous years,” the bulletin reports.

“It is likely that we will start catching SWD any day now. If you do not have traps in place, get them out immediately. If you do, be sure to check them regularly. We will send another message out to all of you when we actually have our first reported catch,” says Colleen Flynn of Purdue University’s Horticulture and Landscape Architecture department in a FancyFruit news bulletin.

Flynn reported that Ricardo Bessin, an entomologist with the University of Kentucky, identified the first SWD of the 2014 growing season in Western Kentucky. Bessin says the detection is in line with a similar time span in 2013.
