The Zika virus and how mosquito control becomes a bigger challenge.

The Zika virus and how mosquito control becomes a bigger challenge. HT CrofAsian Pacific Journal of Tropical Disease.
The recent outbreaks of Zika virus infection occurring in South America, Central America and the Caribbean, represent the most recent of four key arrivals of arboviruses in the Western Hemisphere over the last 20 years. 
Zika virus is mainly vectored by Aedes mosquitoes. The development of effective and eco-friendly mosquito control methods is required in order to minimize the negative effects of currently marketed synthetic pesticides, including multidrug resistance. In this scenario, natural product research can afford solutions as part of integrated pest management strategies. 
In this review, we focused on neem (Azadirachta indica) products as sources of cheap control tools of Aedes vectors. Current knowledge on the larvicidal, pupicidal, adulticidal and oviposition deterrent potential of neem-borne products against the arbovirus vectors Aedes aegypti and Aedes albopictus is reviewed. 
Furthermore, we considered the rising importance of neem extraction by-products as sources of bio-reducing agents for the synthesis of nanoformulated mosquitocides. The last section examined biosafety and non-target effects on neem-borne mosquitocides in the aquatic environment.
Overall, we support the employ of neem-borne molecules as an advantageous alternative to build newer and safer Aedes control tools, in the framework of Zika virus outbreak prevention.  Read the full story here. (PDF paying Download).

Hmmmm..........In my humble opinion the area in which Zika could emerge is greater,, the Aedes albopictus also called the Asian tiger mosquito which transmits among other diseases:dengue (DENV-1, DENV-2, DENV-3, DENV-4), chikungunya (CHIKV), yellow fever (YFV), and Zika) West Nile virus. (See map below and link to my post of February 2016).
