Research Project: Whole Farm Organic Management of Bmsb and Endemic Pentatomids Through Behavior-Based Habitat Manipulation

Location: Beneficial Insects Introduction Research

2013 Annual Report


1a.Objectives (from AD-416):
Biological control offers perhaps the most effective approach to long-term sustainable management of BMSB on organic farms. This project will initially identify key natural enemies and parasitism and predation rates of both native stink bugs and BMSB on organic farms throughout the study area. Other objectives will focus on enhancing the activity of natural enemies through habitat manipulation and conservation management practices specific to organic farming systems, including determining the impact of certified organic pesticides on BMSB natural enemies.


1b.Approach (from AD-416):
The planned role for the Newark laboratory will be to:.
1)provide BMSB eggs from its stock colony to project cooperators for their sentinel surveys in various organic crops;.
2)identify stink bug parasitoids reared in field studies in various crops by other project participants; and.
3)screen pest management compounds registered for organic production on BMSB parasitoids in culture at Newark.


3.Progress Report:

We provided technical support to cooperators for expanded sentinel surveys to monitor parasitism of brown marmorated stink bug (BMSB) by resident native stink bug parasitoids in different crop systems, including providing identifications of specimens. This support was assisted during 2013 with a second workshop on identification of native and exotic BMSB parasitoids (parasitic wasps) that was organized to help educate research collaborators and local extension specialists. Held in conjunction with the BMSB IPM Workgroup meeting in June 2013, a total of thirty-one scientists, extension specialists and students from the US, Canada, Mexico and Switzerland attended the workshop in New Jersey. We compiled and updated a master key for the identification of BMSB parasitoids commonly found in North America. Critical information was shared on native natural enemies of BMSB, their identification and biology, and hands-on training was provided to teach participants to identify specimens obtained in their studies. Preparations were made for the second aspect of the project involving testing of pesticidal products approved for use in organic crops against native natural enemies of BMSB, and during the summer collections of native natural enemies were made to establish laboratory colonies to provide live specimens for testing.
