What is selective for Aedes spp. in sampling immature mosquitoes?

• A. Ovibucket
• B. Ovitrap
• C. New Jersey light trap
• D. Red box

Answer: (B)

Ovitraps target a specific behavior of Aedes: they seek out small, artificial containers to lay eggs. An ovitrap is a dark, water-filled container with a substrate, such as a paper strip, where a gravid female is highly likely to deposit eggs. Because Aedes prefer these container-type breeding sites, the trap effectively collects their eggs (and later larvae), providing a direct measure of Aedes presence and breeding activity at a site. Other options are oriented toward sampling adults or general traps and don’t specifically capture the immature stages of container breeders like Aedes, so they’re not as selective for this purpose.
