Research Project: Identification and Deployment of Rice Stalk Stink Bug, Tibraca Limbativentris, Pheromone

Location: Invasive Insect Biocontrol & Behavior Laboratory

Project Number: 8042-22000-291-02-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Sep 15, 2013
End Date: Sep 15, 2015

The objective of this research is development of a pheromone-based monitoring tool for detection and monitoring of the rice stalk stink bug as a first line of defense against this economically important pest. Although the rice stalk stink bug does not occur in the U.S., having a pheromone-based monitoring tool will help greatly in detection of this potentially invasive species should it be introduced via trade.

EMBRAPA isolated (and patented) three male-specific compounds from the rice stalk stink bug that could serve as sex pheromone (Brazil Patent - PI0604617-7). These compounds were tentatively identified as isomers of 4-(1’,5’-dimethyl-4’-hexenyl)-1-methyl-2-cyclohexen-1-ol but their relative and absolute configurations remain unknown, and field tests have not been conducted to validate attractiveness of these compounds to the rice stalk stink bug. ARS has the expertise to produce the sex pheromone and its stereoisomers which will be used to identify the absolute configuration of the pheromone produced by the insect and ARS will also help to find if single isomers or mixtures can be used to attract this insect in laboratory and field experiments.
