Alligatorweed, Alternanthera philoxeroides, an aquatic amaranth introduced into the United States from South America around the turn of the century, has become a noxious aquatic weed over the past 40 years. Three insects appeared suitable for introduction into the United States as biological control agents of alligatorweed. These insects are 1 Agasicles hygrophila, Coleoptera Chrysomelidae, now commonly known as the alligatorweed flea beetle 2 Amynothrips andersoni Thysanoptera Phlaeothripidae, the alligatorweed thrips and 3 V. malloi, the so-called alligatorweed stem- borer. A general discussion of the biology, feeding behavior, and resulting plant damage of these insects is given. Portions of this document are not fully legible.
