In many parts of the United States, West Nile infections increase during the summer months. What is the reason?ANSWERIt is transmitted person-to-person, and people travel most often during the summer months.It is transmitted by mosquitos, which are more prevalent during the summer months.It is transmitted through water and soil, and people enjoy the outdoors more in the summer.The number of West Nile infections does not change during the year.

The pitcher-plant mosquito (Wyeomyia smithii) has a genetically-controlled behavioral response to changing seasons: these mosquitos transition from an active period of growth and reproduction in warmer months to diapause, or dormancy, in cooler months. The environmental cue that induces mosquitos to enter diapause is daylength, which gets shorter towards the end of the mosquitos’ active period.In the habitat range of the pitcher-plant mosquito, regions that are further south tend to have longer periods of warmth than regions that are further north. So, the active period for mosquitos in southern regions lasts later into the year, when the days are shorter. As a result, the daylengths that induce diapause in southern mosquito populations are, on average, shorter than the daylengths that induce diapause in northern mosquito populations.Researchers have observed that climate change has led to longer periods of warmth in the pitcher-plant mosquito’s northern range.Based on the information above, which of the following best predicts the effect of climate change on the northern populations of pitcher-plant mosquitos?
