Larvae of the common malaria mosquito (Anopheles quadrimaculatus), shown here among pollen in their aquatic habitat, showed low survival rates in a lab study when provided a diet of corn pollen or pine pollen. However, the southern house mosquito (Culex quinquefasciatus) fared well on the pollen diet. The findings suggest corn pollen could help the latter species—key vector of West Nile virus in the U.S.—thrive in habitats near agricultural areas. (Photo by Don Yee, Ph.D., BCE)
