Which option accurately describes a biological bacterial control for mosquitoes?

• A. Chemical Insecticide
• B. Biological Bacterial Control
• C. Cultural Control
• D. Physical Control

Answer: (B)

Biological control uses living organisms or their products to suppress pests. For mosquitoes, this often means applying bacteria that are toxic to the larval stage. Microbial larvicides like Bacillus thuringiensis israelensis (Bti) or related bacteria release toxins in water that specifically kill mosquito larvae when ingested, reducing the number of adults that emerge. This approach is classified as biological bacterial control because it relies on a biological agent rather than chemicals or habitat changes. In contrast, a chemical insecticide relies on synthetic chemicals to kill insects; cultural control involves practices to reduce breeding sites and pest persistence; and physical control uses barriers or traps. Therefore, using a bacterial product to target mosquito larvae best fits the description of biological bacterial control.
