Bactrocera carambolae is the main pest found in sweet starfruit. To the attack of pests B. carambolae can reach 100%. One of the efforts to control B. carambolae pests is the use of entomopathogenic fungi. The use of entomopathogenic fungi because they are safe for the environment and available in nature. The study aimed of was to obtain the best concentration of entomopathogenic fungi Cordyceps militaris L. Fries as a bioinsecticide category against mortality of fruit flies (B. carambolae) in laboratory. The research was conducted at the Plant Pest Laboratory, Faculty of Agriculture, University of Riau from January to March 2024. The research is used a completely randomized design (CRD) consisting of 6 treatments and 4 replicates. The treatment given was the concentrations of local entomopathogenic fungi C. militaris 0 g.l-1 water, 10 g.l-1 water, 20 g.l-1 water, 30 g.l-1 water, 40 g.l-1 water and 50 g.l-1 water. The results showed that the concentration of local C. militaris entomopathogenic fungi 40 g.l-1 water with a conidia density of 1,81 x 108 con.ml-1 can be stated as a bioinsecticide to control B. carambolae imago, because it is able to cause a total mortality of B. carambolae imago 75%, an initial time of death of 24hours after application of local C. militaris and lethal time of 50 (LT50) for 50,75 hours after application of local C. militaris. The appropriate concentration of local C. militaris in killing 50% of the population of B. carambolae imago is 0,95% equivalent to 9,5 g.l-1 water, the appropriate concentration in killing 95% of B. carambolae imago is 19,40% concentration equivalent to 194 g.l-1 water.

Keywords: Bioinsecticide, conidia density, fruit flies, pests.
