Potential distribution of Myllocerus undecimpustulatus undatus (Sri Lankan weevil) in North America

Myllocerus undecimpustulatus undatus Marshall, the Sri Lankan weevil, is a serious plant pest with a wide range of hosts. First identified in the United States on Citrus sp. in Pompano Beach, Broward County, Florida on 15 September 2000, this weevil has over 100 different host plant species including fruits, nuts, vegetables, and ornamentals. It was detected in 12 counties in Florida by May 2006. Historical data from 2000-2012 obtained from the Division of Plant Industry’s field agent submissions was entered into DIVA-GIS, a computer program for mapping and geographic data analysis. The BIOCLIM tool within this program predicted the potential distribution of Sri Lankan weevil in North America. Cold tolerance data was obtained and correlated with DIVA-GIS predictions. This computer program can predict potential distribution of invasive species, which can provide valuable information to assist Extension agents and pest management professionals in evaluating control strategies.
