Can insects be stocked in lakes to control Eurasian watermilfoil?
Early results in other states indicate that aquatic weevils can successfully control milfoil in lakes. The Lake and River Enhancement program in the IDNR Division of Soil Conservation is financially supporting a demonstration project to determine whether these insects can control milfoil in Indiana lakes. Test lakes include Round Lake and Little Turkey Lake in northeastern Indiana and Griffy Reservoir near Bloomington. Weevils were stocked in these lakes during the summer of 2000. Monitoring the success of the study will continue through the summer of 2002. The DNR will be publicizing results of this study as they are generated. The only contractor currently raising and stocking the weevils in Midwestern lakes is EnviroScience, Inc. of Stow, Ohio. If you are interested in having weevils stocked in your lake, you could call the company for information directly at 1-800-940-4025. Exotic watermilfoil is a nuisance in many Indiana lakes.
