Flight-Response of Brown Marmorated Stink Bug to Olfactory Cues from Potential Hosts: Developing Attract & Kill Applications
Commodity Protection and Quality
2013 Annual Report
1a.Objectives (from AD-416):
Enhance production and trade of California tree nuts and tree fruits via development of efficient, economical, and environmentally benign chemical strategies to minimize, or eliminate, insect infestation. Specifically, develop an attract & kill tool for controlling and/or monitoring populations of brown marmorated stink bug (BMSB) in and around production areas.
1b.Approach (from AD-416):
Estimate the relative attractiveness of hosts, BMSB-infested hosts, and BMSB populations by quantifying the flight response of BMSB to volatile chemical cues in a flight tunnel bioassay. Use flight response as diagnostic endpoint to isolate and identify key chemical attractants.
This Assistance Type Cooperative Agreement was established to support Objective 1 of the in-house project and is related to controlling insect pests using techniques that reduce the reliance on postharvest methyl bromide fumigation. The brown marmorated stink bug (BMSB) is a polyphagus insect pest that is of concern to certain countries that import specialty crops from the US. Systems-based approaches to BMSB control are an important part of maintaining the export of specialty crops. The goal of this project is to develope lures and traps for BMSB to be used in concert with systems-based strategies for BMSB control. Research was recently initiated and will focus on diagnosing the attractiveness of BMSB to volatile cues released from California-grown specialty crops, particularly almonds, walnuts, and pistachios.
