Abstract

There were no significant differences in BPH (brown planthopper) control mortality in cages with wood styrofoam bases or with water versus the nutrient salt solution at 1 d. But after 3 d incubation at ambient room temperature, mortality was unacceptably high (more than 20%) in all cages except those with potted plants. Mortality in the petri dish-sucrose cages was highest, with more than 50% of the BPH population drying after 3 d. Hopper mortality on potted plants did not exceed 20% even after 6 d.
