Litsinger, J.A. | Barrion, A.T. (IRRI, Los Banos (Philippines))
Rice and wheat have almost 200 insect pests in common on a worldwide basis, and these are described in terms of habitat, life cycle, and pest status. An analysis of potential pest problems in rice-wheat cropping systems is given and control measures are discussed. The primary control strategy is to limit the carrying capacity of the environment for insect buildup, in tropical environments by community-wide crop scheduling. Wheat has relatively fewer pests than rice as rice is often double- or triple-cropped, but wheat will likely develop more new pest problems as more ecological niches are open. The potentially most serious pest problem in short-season environments is a virus or other disease common to rice and wheat transmitted through a common vector. Comprehensive lists of rice-wheat pests and shared diseases are included
