ely used insect repellants, according to researchers with the USDAs Agricultural Research Service (ARS). The chemicals, particularly one called callicarpenal, showed significant bite-deterring activity against Aedes aegypti, the yellow-fever mosquito, and Anopheles stephensi, which spreads malaria. Callicarpenal and other compounds isolated from the plant also showed repellency against fire ants and ticks, says Charles Cantrell, a researcher with the USDA-ARS in University, Miss.

But research by Jia-Qian Jiang of the University of Surrey in the United Kingdom shows that electrocoagulation is superior to conventional coagulation treatment in removing algae from water.
