The continuing dispersion of Peristenus digoneutis Loan (Hymenoptera: Braconidae), an introduced parasite of the tarnished plant bug, Lygus lineolaris (Palisot) (Hemiptera: Miridae) in Northeastern U.S.A. and Southeastern Canada
Entomological News 119 (1), 77-80
Abstract: Peristenus digoneutis Loan, a European species, was first established by USDA-ARS in New Jersey for the biological control of the tarnished plant bug, which damages many crops. This parasitic wasp has steadily dispersed since its establishment in 1984, and it is now present in 11 states, a 38% increase since our last report in 2003, and has been found in 69 counties in the United States. Peristenus digoneutis is now present in all of the northeastern states, is moving westward along the southern edge of Lake Erie, and is well established in at least three Canadian provinces.
