An update on spotted lanternfly population development
Hello, everyone,
We are continuing our observations on spotted lanternfly, a new invasive to
Virginia, that includes all of our fruit crops, hops, forest trees, and some
vegetables in its host list.
This week we sampled nymphal populations in the known infestation area in the
northern part of Winchester. As expected, nymphs were found on a wide
variety of plants - wild grape, wild cherry, honeysuckle, hackberry, smooth
sumac, and poison ivy. We sampled cultivated grapes - table grapes in an
arbor - and found a population of nymphs there. This is the first record
in Virginia on a crop, rather than wild plants. The nymphs are very
active, and jump readily when disturbed! We found first and second
instars - it will be some time before we expect to find the bright red fourth
instar nymphs.
More later,
Doug
