Abstract: 
This research carried out to determine the chemical composition of Streptomyces sp extract and the toxicity activity of the secondary metabolite against mosquito larvae of Anopheles sundaicus. By using a completely randomized design (CRD), the study was conducted from June to November 2021. The results of the chemical test showed that the isolate of Streptomyces bacteria contains alkaloids, flavonoids and terpenoids. The results of the larvicidal test of the extracts against Anopheles larvae were significantly different (p<0.05) in the number of mortalities between concentrations. The maximum mortality was shown by the extract at a concentration of 500 ppm with an exposing time of 48 hours. In conclusion, the secondary metabolite of Streptomyces bacteria is potential as a larvicide candidate for Anopheline mosquitoes.
