Mosquitocidal activity of a native Bacillus thuringiensis isolate Bt ReX02 from Gunung Jerai Forest, Malaysia against Culex quinquefasciatus and Aedes albopictus.

Background And Objective: To evaluate the mosquito larvicidal potential of the native Bacillus thuringiensis isolate BtReXO2, which was isolated from a tropical rain forest ecosystem in Malaysia. This study also aimed at determining the phenotypic and biochemical characteristics of the isolate.

Materials And Methods: The phenotypic characterization was carried out by growing the isolate in nutrient broth to observe the colonial morphology, vegetative cells, sporulation, motility and haemolytic activity.
