Pest control in shade coffee plantations
According to Kimberly Williams-Guilln from the University of Washington, bats provide a vital service to shade grown coffee plantations: pest control. After analyzing coffee plantations in southern Mexico with acoustic monitoring and DNA testing among other techniques, Williams-Guilln found that several bat species were reducing pests. The research, which will be presented at ESA's 2011 Annual Meeting, shows that, when bats were excluded from accessing the area, there was an 84% increase in arthropod numbers on coffee plants.
The presentation "Ecosystem services of neotropical insectivorous bats in a highly diverse tropical agroforestry system," by Kimberly Williams-Guilln, University of Washington, will be held Tuesday, August 9, 2011 at 8:20 am during the "Conserving Bats to Ensure a Healthy Planet" organized oral session.
