Larval Development – The Sweet Spot
Larval development is highly dependent on the temperature of the water. Seven days is a perfect scenario for a mosquito; however, the temperature must be just right for this to occur, at around 27° C ± 3°C. With more extreme temperatures, you may see higher mortality and longer periods spent in the larval stage. That isn’t to say they won’t emerge in cooler and/or hotter water. Larvae, pupae, and adult mosquitoes are resilient. However, increases and decreases in water temperature can influence the rate at which the larvae develop and larval mortality (Christiansen-Jucht et al. 2014).
What makes a floodwater habitat?
Floodwater habitats can be found anywhere water is collected but can include: Drainage ditches that fill up with storm water, woodland pools after an ice melt, tree holes after a rainstorm, flood plains near streams and rivers, in meadows where depressions fill up after rain, citrus furrows and pastures from irrigation, and fresh and saltwater marshes.
