Dengue fever (DF) is a viral disease caused by the dengue virus, which transmitted mosquitoe Aedes aegypti and endemic in some cities of Saudi Arabia, such as Jazan area. And because toxicity chemical- insecticides used pest control programs, therefore, there need to use effective safe alternative methods eliminate pests. Therefore, current study aimed bacterium Bacillus thuringiensis biocide against larval stages Ades aegypti. var. israelensis was applied two formulations, (water-dispersible powder Liquid formulation), were examined for their immature adult laboratory. Results indicated that 50 % lethal concentration (colony forming unit, CFU) B.t.israelensis 4th instars, 8.31x105 CFU mL-1 liquid formulation 6.72 x105 gm-1 wettable powder. Bioassay data also showed pupation percent emergence affected more subjecting larvae than formulation. The mortality values adults ranged between 49.33 & 64.23 when using powder, respectively.
