Abstract : The greatest success with the Agasicles as a biocontrol for alligator weed has been at experimental sites in Florida. The increased effectiveness of the alligator weed beetle in this area is believed to be related to the ability of the insect to overwinter. The Agasicles population usually has two peaks of activity in Florida as compared with one in other states. Alligator weed mats present at the beginning of the study reported herein have decreased in size and thickness. Plant competition has played an important role in controlling the alligator weed at the Goose Creek site by Agasicles and at several other sites in the southeastern states. The feeding of the Agasicles on alligator weed decreases its ability to compete with other aquatic plants. Other insects may be used to extend control over a greater geographic area. (Author)
