Bti stands for which organism?

Explanation:
Bti stands for a specific bacterial subspecies used as a targeted biological control for mosquitoes. It is Bacillus thuringiensis israelensis, the strain that produces toxins (Cry and Cyt) when ingested by mosquito and black fly larvae, disrupting their gut and killing them. This makes it a preferred option for larval control because it acts specifically on dipteran larvae and is relatively safe for non-target organisms, including humans. The other options refer to different organisms: the kurstaki subspecies targets caterpillars, Bacillus subtilis is a different Bacillus species with other uses, and Pseudomonas aeruginosa is a separate bacterium not used as a mosquito-larvae biocontrol agent.
