The flying range of Aedes aegypti is
**Core Concept**
The flying range of Aedes aegypti is a crucial factor in its ability to spread diseases such as dengue fever and Zika virus. Aedes aegypti is a highly domesticated mosquito species that is capable of flying short to medium distances in search of food and breeding sites.
**Why the Correct Answer is Right**
The correct answer is based on the mosquito's behavior and physiology. Aedes aegypti is known to fly up to 100 meters from its breeding site in search of a potential host for blood-feeding. This distance is sufficient for the mosquito to reach nearby houses or buildings but not far enough to reach distant locations. The mosquito's flying range is influenced by factors such as wind direction, temperature, and humidity.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it is not supported by scientific evidence. Aedes aegypti's flying range is not typically considered to be over 1 kilometer.
* **Option B:** This option is incorrect because it is too low. While Aedes aegypti can fly short distances, its flying range is typically greater than 50 meters.
* **Option D:** This option is incorrect because it is too high. Aedes aegypti is not capable of flying long distances like other mosquito species.
**Clinical Pearl / High-Yield Fact**
It's essential to note that Aedes aegypti's flying range is influenced by the presence of breeding sites and the availability of food sources. In areas with high mosquito breeding activity, the flying range of Aedes aegypti can be increased.
**Correct Answer:** C. 100 meters
