Pre-harvest yield losses due to rice insect pests can be significant. This is especially so under pest outbreak scenarios. Irrigated rice has been shown to be an agro-ecosystem with rich biodiversity and a redundant food chain (Schoenly et al. 1996, Wilby et al. 2006). Insecticide abuse negatively affects the natural enemy communities, shortens the food chain length and increases the propensity for pest outbreaks in irrigated rice ecosystems (Heong and Schoenly 1998, Settle et al. 1996, Way and Heong 1994). An alternative framework for insect pest management is needed to address the vulnerability of the rice crop to specific pests, without introducing a higher risk of pest outbreaks.
