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
