Abstract

The purpose of this study was to determine the population of mealybugs before and after application of the fungus Beauveria bassiana, to determine the mortality of mealybugs after application of the fungus Beauveria bassiana, and to determine the appropriate dose of the fungus Beauveria bassiana to control mealybugs.

Based on the results of the study, the identification of the attack rate of mealybugs (Pseudococcus citri) on cocoa (Theobroma cacao L.) and efforts to suppress its attack with the fungus Beauveria bassiana, it can be concluded that: After application of the fungus Beauveria bassiana the population of mealybugs showed a decrease. The mortality of mealybugs after application of the fungus Beauveria bassiana was 100%. The best and most effective dose in suppressing the attack of mealybugs is 5 g/liter of water. To suppress the attack of mealybugs, it is recommended to use a dose of 5 g/liter of water by spraying it on the fruit and then wrapping it in plastic so that the fungus can be more effective.
