First record of oligosita sanguinea (Girault) (Hymenoptera: Trichogrammatidae) as an Egg Parasitoid of Hymetta balteata Mcatee (Hemiptera: Cicadellidae) in Upstate New York

The leafhopper Hymetta balteata McAtee (Hemiptera: Cicadellidae) is a grape-feeding species with a distribution in Central and Eastern USA (Dmitriev and Dietrich, 2007). Although H. balteata is able to feed and possibly reproduce on various Vitis spp., unlike some other leafhoppers, H. balteata is not considered a pest of cultivated grapes in the Finger Lake grape-growing region of Upstate New York or elsewhere. This can be explained perhaps by a combination of factors, such as cultivated grapes, particularly Vitis vinifera, not being the preferred plant host of this leafhopper and the likely good control provided by its natural enemies, particularly egg parasitoids, which has not yet been demonstrated. In Upstate New York, H. balteata is common yet seemingly relatively scarce on wild grape, Vitis riparia, which is integral part of the local native landscape.
