Abstract

Summary

Native insect predators and parasitoids can help regulate invasive insect pest species. The brown marmorated stink bug, Halymorphahalys (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 plant-ings. 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.

  

Sumario

 

Los depredadores y parasitoides nativos de insectos pueden ayudar a regular las especies invasoras de plagas de insectos. El chinche café marmorado Halymorpha halys (Hemiptera: Pentatomidae,) es una plaga introducida de frutas y verduras en el este de los Estados Unidos que se originó en Asia. En los sondeos para los agentes de control biológico nativo de esta plaga se detectó la avispa predadora crabronida Astataunicolor (Hymenoptera: Crabronidae) y el insecto predador generalist Arilus cristatus (Hemiptera: Reduviidae) utilizando las ninfas y adultos de esta plaga introducida como presa. La distribución temporal de la avispa fue determinada a partir de trampas de pozo de agua y colecciones con redes durante 5 años en tiras de flores provisionales que fueron establecidas para programas de conservación de polinizadores en los huertos de árboles frutales. Las trampas de paletas azules utilizadas para el monitoreo de las abejas no capturaron A. unicolor en las plantas para los polinizadores. No se encontró Astata unicolor en 6 huertos de manzanas comerciales que fueron monitoreados simultáneamente utilizando trampas de platos y de paletas azules durante un período de 4 años.
