Which genus is primarily targeted by Gravid traps?

• A. Aedes
• B. Anopheles
• C. Culiseta
• D. Culex

Answer: (D)

Gravid traps target female mosquitoes that have already taken a blood meal and are ready to lay eggs. The trap mimics a good breeding site with water and attractants, drawing in these gravid females as they search for a place to oviposit. Culex species are especially attracted to these oviposition cues and commonly breed in standing, often polluted water, so they are the genus most effectively sampled by grav traps. Aedes and Anopheles have different breeding preferences and behaviors, making them less consistently captured by this trap type, and Culiseta is not the primary target. So, the genus primarily targeted by Gravid traps is Culex. These traps are useful for monitoring Culex populations and related disease risks.
