Abstract
The topical toxicities of eight insecticides in susceptible (S), malathion-resistant (Rm) and fenvalerate-resistant (Rmf) strains of the brown planthopper were determined. The negatively correlated cross resistance was observed between malathion and fenvalerate. The insecticidal activity of fenvalerate (racemic) wholly depends on that of fenvalerate A.
