Which of the following temperatures is generally unfavorable for mosquito survival?

The chosen temperature, which is 35°F, is generally unfavorable for mosquito survival because it falls below the threshold that mosquitoes can tolerate for active metabolism and reproduction. At low temperatures, like 35°F, mosquitoes can become sluggish and may enter a state of diapause or dormancy to survive until favorable conditions return. This low temperature can also lead to freezing, which is lethal to many mosquito species.

Mosquitoes are more active and can thrive in warmer temperatures, typically between 70°F and 95°F. During these conditions, they are not only able to move freely but also engage in breeding and feeding behaviors. The range of 50°F is generally still manageable for mosquitoes, allowing them to remain active, albeit at a reduced capacity when compared to warmer temperatures.

Overall, the low temperature of 35°F creates an environment that is detrimental to mosquito survival, making it the correct answer.
