Neonicotinoid resistance in rice brown planthopper, Nilaparvata lugens

open access: yesPest Management Science, 2008
AbstractBACKGROUND: Rice brown planthopper, Nilaparvata lugens Stål, is a primary insect pest of cultivated rice, and effective control is essential for economical crop production. Resistance to neonicotinoid insecticides, in particular imidacloprid, has been reported as an increasing constraint in recent years.
