Low Levels of Common Insecticide Can Decimate Tadpole Populations, Pitt Research Shows

The latest findings of a University of Pittsburgh-based project to determine the environmental impact of routine pesticide use suggests that malathion—the most popular insecticide in the United States—can decimate tadpole populations by altering their food chain, according to research published in the Oct. 1 edition of Ecological Applications.

Gradual amounts of malathion that were too small to directly kill developing leopard frog tadpoles instead sparked a biological chain of events that deprived them of their primary food source. As a result, nearly half the tadpoles in the experiment did not reach maturity and would have died in nature. The research was funded by a National Science Foundation grant.
