Abstract

Rice (Oryza sativa L.) is one of the world’s most important food crop and is the most widely consumed staple food for a large part of the world’s human population, especially in Asia. The average per hectare yield in the country tends to be relatively low compared to China, Sri Lanka, mainly due to heavy losses caused by pests. Rice crop is attacked by 800 species of insect pests in both field and storage. Among these one of the most economically important insect pests is the Brown planthopper (BPH), Nilaparvata lugens (Stal.) (Homoptera: Delphacidae). The BPH has become more problematic, posing a threat to rice production throughout South and South East Asia. Due to
infestation plants turn yellow and dry up rapidly. At early infesta tion, round and yellow patches appear, which soon turn brownish due to the drying up of the
plants and is called as ‘Hopper burn’ which is reported to cause yield loss ranging from 10-75% (Tirumala rao, 1950).
