Which species has a typical flight distance measured in yards, specifically 100-200 yards?

• A. Aedes albopictus (Asian Tiger Mosquito)
• B. Aedes aegypti
• C. Anopheles quadrimaculatus
• D. Culex quinquefasciatus

Answer: (A)

Dispersal distance is a key factor in understanding how mosquitoes move from breeding sites to hosts. Among common vectors, Aedes albopictus tends to fly farther from its breeding site than some other species, and field studies typically report active flight distances in the 100-200 yard range (roughly 90-180 meters). This means an adult may move from one yard to neighboring yards, helping explain why control efforts must extend beyond the immediately infested property to nearby yards. The other species listed are usually more localized or associated with particular microhabitats and hosts, so their typical active flight distances do not match this 100-200 yard range as consistently. Aedes aegypti often remains closer to human habitations, while the Anopheles quadrimaculatus and Culex quinquefasciatus tend to be tied to different breeding sites and can have variable dispersal, but the classic 100-200 yards figure is most characteristic of Aedes albopictus.
