D3103: Elucidating the key volatiles involved in rice-rice stink bug interactions

Understanding the interactions between plants and insects is important to better manage pests in the field. The rice stink bug (Oebalus pugnax) (RSB) affects rice plants by reducing yield and quality of the grain. In rice-growing areas in the US, sweep sampling is the main tool used to establish population levels and implement treatment thresholds. Strategies such as weed control, biological control and use of pesticides are ways to reduce source populations of RSB. Knowledge of the volatiles emitted by developing rice grains can help in detecting infestation.  The goal of this study is to improve knowledge of the key volatiles emitted by different stages on rice plants differ, that feeding by stink bugs changes the volatiles emitted by rice panicles, and the volatiles emitted by rice attract RSB.
