Mortality of Adult Brown Planthoppers (BPH) in Different Types of Cages Used for Bioassays of Entomopathogenic Fungi
International Rice Research Institute Newsletter
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.
