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.

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: 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.

This book was released on 1984 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alligatorweed and waterhyacinth are two of the most troublesome aquatic plants in the United States. In research sponsored by the Corps of Engineers' Aquatic Plant Control Research Program (APCRP) three insects were identified for alligatorweed control, the alligatorweed flea beetle (Agasicles hygrophila Selman and Vogt), the alligatorweed stem borer (Vogtia malloi Pastrana), and the alligatorweed thrips (Amynothrips andersoni O'Neill). Three insect species have also been identified by APCRP as biocontrol agents of waterhyacinth. These insects include the mottled waterhyacinth weevil (Neochetina eichhorniae Warner), the chevroned waterhyacinth weevil (Neochetina bruchi Hustache), and the Argentine waterhyacinth moth (Sameodes albiguttalis Warren). Discussion of aquatic weed problems between the U.S. Army Engineer District, Galveston, and the Waterways Experiment Station (WES) resulted in a proposal being a submitted by WES to assist in controlling aquatic weed problems for the Galveston District. A framework for introduction and evaluation of all insect species was established. Previously introduced insect species in alligatorweed would also be investigated, with special emphasis placed on the determination of environmental factors that may be limiting the effectiveness of these insects in controlling alligatorweed.

Download or read book Global Climate Change and Terrestrial Invertebrates written by Scott N. Johnson and published by John Wiley & Sons. This book was released on 2017-02-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invertebrates perform such vital roles in global ecosystems—and so strongly influence human wellbeing—that biologist E.O. Wilson was prompted to describe them as “little things that run the world.” As they are such powerful shapers of the world around us, their response to global climate change is also pivotal in meeting myriad challenges looming on the horizon—everything from food security and biodiversity to human disease control. This book presents a comprehensive overview of the latest scientific knowledge and contemporary theory relating to global climate change and terrestrial invertebrates. Featuring contributions from top international experts, this book explores how changes to invertebrate populations will affect human decision making processes across a number of crucial issues, including agriculture, disease control, conservation planning, and resource allocation. Topics covered include methodologies and approaches to predict invertebrate responses, outcomes for disease vectors and ecosystem service providers, underlying mechanisms for community level responses to global climate change, evolutionary consequences and likely effects on interactions among organisms, and many more. Timely and thought-provoking, Global Climate Change and Terrestrial Invertebrates offers illuminating insights into the profound influence the simplest of organisms may have on the very future of our fragile world.
Download or read book Biological Control of Weeds in Australia written by Jim Cullen and published by CSIRO PUBLISHING. This book was released on 2012-03-05 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological control of weeds has been practised for over 100 years and Australia has been a leader in this weed management technique. The classical example of control of prickly pears in Australia by the cactus moth Cactoblastis cactorum, which was imported from the Americas, helped to set the future for biocontrol of weeds in many countries. Since then there have been many projects using Classical Biological Control to manage numerous weed species, many of which have been successful. Importantly, there have been no serious negative non-target impacts – the technique, when practised as it is in Australia, is safe and environmentally friendly. Economic assessments have shown that biocontrol of weeds in Australia has provided exceedingly high benefit-to-cost ratios. This book reviews biological control of weeds in Australia to 2011, covering over 90 weed species and a multitude of biological control agents and potential agents. Each chapter has been written by practising biological control of weeds researchers and provides details of the weed, the history of its biological control, exploration for agents, potential agents studied and agents released and the outcomes of those releases. Many weeds were successfully controlled, some were not, many projects are still underway, some have just begun, however all are reported in detail in this book. Biological Control of Weeds in Australia will provide invaluable information for biological control researchers in Australia and elsewhere. Agents used in Australia could be of immense value to other countries that suffer from the same weeds as Australia. The studies reported here provide direction to future research and provide examples and knowledge for researchers and students.

Available in PDF, EPUB and Kindle. Book excerpt: As well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. Chapters contributed by leading international researchers and practitioners in all areas of biological control afford the book a breadth of coverage and depth of analysis not possible with a single author volume. Combined with the use of other experts to review chapters and editorial oversight to ensure thematic integrity of the volume, this book provides the most authoritative analysis of biological control published. Key aspects addressed include how success may be measured, how successful biological control has been to date and how may it be made more successful in the future. With extensive use of contemporary examples, photographs, figures and tables this book will be invaluable to advanced undergraduate and postgraduate students as well as being a `must' for all involved in making biological control successful.
