Parasitism Rate of Sentinel Pests in Different Treatments in Rice Fields

Gaballah Md

Rice is the most important staple food for a large part of the world’s human population, especially in East and South Asia, the Middle East, Latin America, and the West Indies 1 .Globally, rice provides more than one-fifth of the calories consumed by humans. Outbreaks of rice-feeding insect pests are thus a serious threat to food security. Recently, rice yield losses increased due to widespread outbreaks of the brown plant hopper, rice leaf-folder, small brown plant- hopper, rice hispa, yellow stem borer and white-backed plant-hopper. These pests cause hundreds of millions of dollars of losses every year and threaten food security in regions where rice is the staple food. Recent studies have shown that insect pest outbreaks can be traced to the misuse of insecticides threatening the entire rice ecosystem.
