Download or read book The Relative Impact of Single Vs. Multiple Agents on the Biological Control of Tansy Ragwort (Senecio Jacobaea) written by Rosalind R. James and published by . This book was released on 1989 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field experiments were done to test the relative effectiveness of single and multiple biological control agents in reducing weed populations using two insects, the cinnabar moth, Tvria iacobaeae (L.), and the ragwort flea beetle, Lonqitarsus iacobaeae (Waterhouse). These two insects were released for biological control of the biennial weed tansy ragwort. Together, they had a greater impact on ragwort, at the experimental site, than either alone. Artificial defoliation simulated the cinnabar moth feeding behavior of defoliating and defoliating bolting plants in the early summer. Flea beetle larvae and adults were sampled to determine their seasonality and the plant parts and stages they most frequently fed on. Larvae fed internally in the leaf petioles and roots from October to July. Adults fed on leaves year round with their greatest activity occurring in late summer and fall. Flea beetles alone reduced vegetative plant densities by about 95%, but only with simulated cinnabar feeding did they affect flowering plants, reducing regrowth of leaves and flowers. Cinnabar moths alone had an effect only on flower and seed production. This combination of herbivores with little nicheoverlap, spread out attack over time, plant stages, and parts, and yielded stronger host population depression than either insect yielded alone.

Download or read book Field Guide for the Biological Control of Weeds in the Northwest written by Rachel Winston and published by Government Printing Office. This book was released on 2017-12-13 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide focuses on the most problematic weeds in eastern North America for which there are at least some biocontrol agents established and/or available. Multiple photos and descriptions of each weed included in this guide emphasize key identification traits and plant ecology. For each weed included in this guide, all biocontrol agents released or currently found in North America are described individually. Photos highlighting key identification features and damage are included. The release history, current status, and recommended use of each biocontrol agent are described in detail. Recommendations and current impact often vary between the US and Canada, therefore, the information is presented separately. Includes international code of best practices for classical biological control of weeds.

Download or read book Biological Control: Measures of Success written by G. Gurr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. 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.
