What does BTI stand for in the context of mosquito control?

Bacillus thuringiensis (var.) israelensis is a specific strain of the bacterium Bacillus thuringiensis that is known for its effectiveness as a biological pesticide, especially against mosquito larvae. This strain produces toxins that are harmful to the larvae when ingested, offering a targeted approach to mosquito control without adversely impacting beneficial insects or the environment.

The correct answer highlights the specificity of BTI as it relates to both its biological classification and its application in pest control. Bacillus thuringiensis itself is a naturally occurring bacterium that has been utilized in pest management due to its safety and effectiveness, and the "israelensis" variant is uniquely suited for controlling mosquitoes, making it a popular choice in various pest management programs.

Understanding the proper designation of BTI reinforces its role in integrated pest management strategies and helps ensure effective and environmentally responsible use, as well as compliance with pest control regulations.
