Available in PDF, EPUB and Kindle. Book excerpt: Applications of 2 lb/A 2,4-dichlorophenoxy acetic acid (2,4-D) coordinated with alligatorweed flea beetle (Agasicles hygrophila) feeding damage resulted in the deterioration of subsurface mats of alligatorweed (Alternanthera philoxeroides (Mart.) Griseb.). The constant pressure on the surface alligatorweed growth, when using the integration method, appeared to deplete the subsurface carbohydrate reserves in alligatorweed stems. The integrated control in laboratory and small plot experiments has yielded a greater reduction of floating alligatorweed mats than is attainable with either agent alone. (Modified author abstract).

Book excerpt: The use of herbicides coordinated with insect-feeding damage as a method for alligator weed management is discussed. Detailed studies on the integrated control method include the details of the research program relating to an integrated approach, the effects of water quality on the distribution of alligator weed and water hyacinth, the effects of water hardness on herbicide toxicity, and the evaluation of promising herbicides for the control of alligator weed and water lettuce. Color illustrations reproduced in black and white.

Book excerpt: 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).

Book excerpt: 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.

This book was released on 2011 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Alligator weed (Alternanthera philoxeroides) is a major weed of world importance and a “weed of national significance” to Australia where it is proclaimed noxious in all states. In spite of a concentrated effort with herbicides and insect biological control, the core infestation in NSW is still inadequately controlled and acts as a reservoir for new outbreaks throughout Australia. Inundative biological control with plant pathogens (mycoherbicide) is seen as a “softer” alternative to chemicals and could be integrated with existing control methods to give better levels of control." (ABSTRACT, l. xviii).

Book excerpt: The goal of this project was to improve management of alligator weed in Australia. This was to be accomplished through; 1) testing the host specificity of two herbivorous insects for potential use as biological control agents and 2) completing ecological studies to better understand the weed in order to develop and promote more effective methods of control.
