15. Control options for invasive mosquitoes
•Eliminate breeding sources
•Larvicides
•chemicals, insect growth regulators
•Adulticides
•habitats are challenging

Global map of the predicted distribution of Ae. aegypti.The map depicts the probability of occurrence (from 0 blue to 1 red) at a spatial resolution of 5 km × 5 km.DOI: http://dx.doi.org/10.7554/eLife.08347.004
My lab is California’s central diagnostic laboratory for testing mosquitoes for Zika, chikungunya, dengue, and other arboviruses. In response to the ongoing outbreak, we now have a validated test to detect Zika virus in mosquito pools via RT-PCR, and we have developed a new diagnostic test to identify invasive mosuitoes (Zika vectors Aedes aegypti and Aedes albopictus) based on protein signatures from eggs collected in traps. This will provide new spatial information on the distribution and spread of the mosquitoes.
The CalSurv Gateway was built in part with NASA funding, originally as a decision-support system for West Nile virus. Our latest NASA Health & Air Quality project focuses on decision support tools for controlling the invasive mosquitoes, Aedes aegypti and Aedes albopictus, and for estimating and mapping the risks for dengue, chikungunya, and Zika viruses. This slide shows our new real-time maps that present real-time surveillance maps for the invasive mosquitoes, and our climate-based suitability estimates for Aedes aegypti in the U.S.

Length of winter vs sum of annual daily reproductive rates.
Expect areas with the shortest winters (longest reproductive seasons) and the highest sum of reproductive rates, to have the highest estimated population growth given a mosquito introduction.
These are in the bottom right.
Upper left, would have the lowest estimated population growth.
Red are where aegypti have been detected
Blue not detected
Many red are in the bottom right, where we would expected population growth and thus likelihood of persistence to be high
Understanding where your city lies on this graph is useful in understanding how you would expect aegypti populations to grow in your region.
