Abstract

Summary Native insect predators and parasitoids can help regulate invasive insect pest species. The brown marmorated stink bug, Halymorpha halys (Hemiptera: Pentatomidae), is an introduced pest of fruits and vegetables in the eastern USA that originated in Asia. Surveys for native biological control agents of this pest detected the crabronid predatory wasp Astata unicolor (Hymenoptera: Crabronidae) and the generalist predatory bug Arilus cristatus (Hemiptera: Reduviidae) using the nymphs and adults of this introduced pest as prey. Temporal distribution of the wasp was determined from water pan traps and net collections over 5 years in floral provisioning strips that were established for pollinator conservation programs in tree fruit farms. Blue vane traps used for bee monitoring did not capture A. unicolor in pollinator plantings. Astata unicolor was not found in 6 commercial apple orchards that were monitored concurrently using either pan or blue vane traps over a 4 yr period.
