Rearing Stink Bugs for Development of Monitoring and Management Tools for Selected Stink Bug Crop Pests
Invasive Insect Biocontrol and Behavior Laboratory
2013 Annual Report
1a.Objectives (from AD-416):
The objective of this cooperative agreement is the continuance of the source colony of stink bugs, currently Euschistus heros (F.) and Nezara viridula (L.) (Hemiptera: Pentatomidae) for use with bioassays of chemical, biological, semiochemical, and plant-incorporated management of these crop pests. Species may be altered by mutual agreement.
1b.Approach (from AD-416):
ARS/IIBBL maintains a colony of two species of pest/stink bugs for study of management tools to protect crops of interest. ARS will provide healthy stink bug eggs to Sponsor each week (approximately 1,000 each species). This new Trust Fund Cooperative Agreement (updating TFCA 58-1275-6-321) will allow the continued development of standardized laboratory tests and plant tissue feeding studies essential for the evaluation of plant-produced pesticidal substances and for the development of related risk assessments. Sponsor will support, solely by the monetary contribution specified, the upkeep and development of USDA-ARS stink bug colonies to assist in the development of biological and semiochemical research on stink bug pests and their natural enemies, under the Project 1275-22000-272, Insect Management Systems for Urban Small Farms and Gardens, and will assist IIBBL with rearing techniques and technologies. Both organizations will use the stink bug populations independently to develop monitoring and management tools for selected stink bug crop pests.
Source colony has provided the insects for studies of dietary behavior, development, and response to toxins. Eggs of both species were shipped weekly to sponsor. Sponsor aims to continue the development of insecticidal and/or transgenic means to address pest shifts resulting from changing crop and agronomic practices. IIBBL is engaged in independent projects to assess tools for the monitoring and/or management of stink bugs relating to agricultural crops and ecosystems, and aims to gain increased understanding of the behavior and ecology of stink bug pests, through studies supported by its maintenance of the colonies.
