Insect warning colors aid cancer and tropical disease drug discovery
Date:7/8/2008

Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers at Smithsonian's Tropical Research Institute in Panama. Such clues could speed drug discovery and provide insight into the ecological relationships between tropical-forest plants and insects that feed on them. The report is published in the Ecological Society of America's journal Frontiers in Ecology and the Environment.

"These findings are incredibly exciting and important," said Todd Capson, STRI research chemist, who directed the project. "The results of this study could have direct and positive impacts on the future of medical treatment for many diseases around the world."

For this research scientists used plants already known to have anti-cancer compounds; those proven to be active against certain disease-carrying parasites; and plants without such activity. The study showed that beetles and butterfly larvae with bright warning coloration were significantly more common on plants that contained compounds active against certain diseases, such as breast cancer and malaria. There was no significant difference in the number of plain-colored insects between plants with and without activity, according to the study by the Smithsonian's Panama International Cooperative Biodiversity Group Program.

"We put two and two together," said researcher Julie Helson. "We knew that brightly colored insects advertise to their predators that they taste bad and that some get their toxins from their host plants. But because other insects cheat by mimicking the toxic ones, we weren't sure if insect color was really going to work to identify plants containing toxinsit did!" Helson was a student at McGill University when she conducted this research in 2005.
