- Abstract
The rice bug (Leptocorisa acuta) is an important pest of rice plants that can significantly reduce rice production. One effective control technique is biological control, which utilizes the entomopathogenic fungus, Beauveria bassiana. This study aimed to test the mortality rate of L. acuta exposed to the entomopathogenic fungus B. bassiana. The study employed a completely randomized design with six treatments, each repeated ten times. The treatments involved varying concentrations of B. bassiana (g.L-1): 0 (control 1), 5, 10, 15, and 20, and deltamethrin of 2 mL.L-1 as control 2. The data obtained were analyzed using analysis of variance. Further examinations using the least significant difference (LSD) test at 5% were conducted for the data showing significant differences. The results showed that on the tenth day, the highest mortality percentage was found in the concentration of B. bassiana 20 g.L-1 with a rate of 78%, whereas insecticide (deltamethrin) showed a mortality rate of 87%. The results of the probit analysis showed that the LT50 value at a concentration of B. bassiana 20 g.L-1 reached on days 7th; 15 g.L-1 reached on days 8th; 10 g.L-1 reached days 10th; 5 g.L-1 reached days 11th, with an LC50 value of 5.77 or at a concentration of 20 g.L-1. The virulence of B. bassiana infected with L. acuta occurred on the second day after application.
