Which Aedes species breeds in irrigated pastures?

• A. Ae. melanimon, Ae. nigromaculis, Ae. vexans
• B. Ae. melanimon
• C. Ae. nigromaculis
• D. Ae. vexans

Answer: (A)

In this case, the main idea is how Aedes mosquitoes utilize agricultural water sources for larval development. Irrigated pastures create shallow, sunlit pools and ditches that persist between irrigation events, providing ideal standing-water habitats for certain Aedes species to lay eggs and for larvae to develop. The combination of Ae. melanimon, Ae. nigromaculis, and Ae. vexans is the best match because these species are commonly associated with irrigation-related habitats like pastures where water collects or stands temporarily. The other options point to individual species, but the question is asking which group is typically found breeding in irrigated pastures, and this trio collectively reflects that habitat association.
