Arthur T Knackerbracket has found the following story:

Mosquitoes aren't just blood thirsty. They also have a sweet tooth, relying on plant nectar to get the sugar they need to survive. Exploiting this weakness, scientists have developed an environmentally friendly eradication method. The new, inexpensive technique tricks these annoying pests into gorging themselves on insecticides laced with a concoction that mimics the sweet-smelling scents and aromas that they find irresistible. It could bolster efforts to suppress malaria, Zika and other mosquito-borne diseases worldwide.

The researchers are presenting their work today at the 254th National Meeting & Exposition of the American Chemical Society (ACS).

"The blend of chemicals that we use to attract mosquitoes is so powerful that they will ignore natural plant odors and attractants in order to get to our formulation," says Agenor Mafra-Neto, Ph.D. "From a mosquito's point of view, it's like having an irresistible chocolate shop on every corner. The product is so seductive that they will feed on it almost exclusively, even when it contains lethal doses of insecticide."

Conventional chemical insecticides used to control mosquitoes are used as cover sprays, frequently dispersed over wide areas. But this blanket spray approach exposes people and animals to potentially harmful compounds and can kill bees and other beneficial insects. In addition, residues of these sprays can contaminate soils and streams, as well as promote increased pesticide resistance. To overcome these issues, Mafra-Neto of ISCA Technologies and colleagues at several universities sought to create a more targeted approach using an insecticide potion spiked with a blend of semiochemicals, or chemical signals, that mosquitoes can't resist.

    What are the chances that other inseccts/animals would also get attracted by the sweet smell? And yeah, what about the animals that feed on mosquitos?
