As well as dieting on blood, mosquitoes also like to snack on "sweets," generally nectar from flowers and nectaries on plant leaves and stems.
Scientists are attempting to exploit this habit to help get rid of the pests.
Researchers sprayed acacia trees with a solution of sugar mixed with the insecticide Spinosad. The result was the elimination of almost the entire mosquito population of the nearby area.
Mosquitoes' habits would allow for targeted spraying. Of 77 flowering plants in Wisconsin, for example, mosquitoes prefer only four. However, desert and savannah regions, where malaria is on the rise due to such factors as environmental changes and the growing resistance of mosquitoes to conventional insecticides, would benefit most.
