Combining Bti and Bsph is used to address what aspect of mosquito control?

Explanation:
Combining Bti and Bsph targets resistance management in mosquito control. Both are bacterial larvicides that kill larvae, but they use different toxins and modes of action. By applying them together, a mosquito population would have to develop resistance to multiple toxins at once, which is much less likely. This slows or prevents the evolution of resistance and helps keep larviciding effective over time. The other options don’t reflect the main purpose: these products are not used primarily to eliminate non-target species, nor do they accelerate larval development or increase adult lifespan.
