Seasonal Captures of (Ashmead) (Hymenoptera: Scelionidae) and the Effects of Habitat Type and Tree Species on Detection Frequency.

, an important egg parasitoid of in Asia, was first detected in the USA in 2014. To evaluate the effect of habitat and the seasonality of detections in the USA, yellow sticky traps were placed in the canopy of growing at the edge of isolated patches of trees, windbreaks, and woodlots in northern Virginia in 2018 and 2019. In both years, captures occurred from May to September, and peaked in July and August. While was detected in all habitats, there was not a consistent effect of habitat type on capture frequency. To evaluate tree species effects on captures, in 2017 and 2018, yellow sticky traps deployed in the canopy of bordering apple orchards were paired with a nearby trap in one of several wild tree species along a common woods edge. In 2019, these traps were deployed in , black walnut, and black locust growing in the same windbreaks. No consistent association between captures of or native parasitoids of and the tree species sampled was observed among years. Results are discussed in relation to the ecology and sampling optimization of .
