rnAll of the following are true about Aedes mosquito, except:
**Core Concept**
Aedes mosquitoes are a primary vector for several diseases, including dengue fever, Zika virus, and chikungunya. These mosquitoes are known for their ability to breed in small, stagnant water collections and their distinctive behavior as day-time biters. Understanding the life cycle and breeding habits of Aedes mosquitoes is crucial for effective disease prevention and control.
**Why the Correct Answer is Right**
Aedes mosquito eggs are designed to survive in a water-free state, allowing them to be transported to new locations and then hatch when they come into contact with water. This unique adaptation enables Aedes mosquitoes to quickly colonize new areas and establish breeding sites. In contrast to other mosquito species, Aedes eggs can survive for several weeks to several months without water, allowing them to withstand dry conditions and still maintain their viability. This remarkable ability to survive in a water-free state is not a characteristic of Aedes mosquitoes.
**Why Each Wrong Option is Incorrect**
**Option A:** Aedes mosquitoes are indeed a primary vector for dengue fever, and this statement is true.
**Option B:** Aedes mosquitoes do breed in stagnant water, making this statement true as well.
**Option C:** Aedes mosquitoes are known to be day-time biters, which is a distinctive characteristic of these mosquitoes and a reason why they are effective vectors for disease transmission.
**Clinical Pearl / High-Yield Fact**
It's essential to note that Aedes mosquitoes can breed in as little as 1 cm of standing water, making them a significant public health concern in urban areas. This highlights the importance of proper waste disposal, water management, and mosquito control measures in preventing the spread of disease.
**β Correct Answer: D. Its eggs cannot survive more than one week without water**
