This book was released on 1934 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is the result of studies begun in 1915 at the Melrose Highlands, Mass., laboratory of the Bureau of Entomology to determine the native hosts of the introduced parasites of the gypsy moth (Porthetria dispar L.) and the brown-tail moth (Nygmia phaeorrhoea Don.), and to determine the possible effect of these parasites on the native hosts.

This book was released on 1959 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication reports one phase of studies designed to acquire new knowledge on the distribution, food plants, life histories, and parasites of lepidopterous insects in Northeastern United States. This kind of knowledge is basic for all methods of controlling forest insect pests. The information contained in this report will be of particular value to entomologists and students interested in biological control.

Download or read book Caterpillars in the Middle written by Robert J. Marquis and published by Springer Nature. This book was released on 2022-04-22 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caterpillars are excellent model organisms for understanding how multiple selective forces shape the ecology and evolution of insects, and organisms in general. Recent research using the tools of modern molecular biology, genetics, metabolomics, microbial ecology, experiments conducted at a global level, network analysis, and statistical analyses of global data sets, combined with basic natural history, are yielding exciting new insights into caterpillar adaptations and ecology. The best way to view these research advances is within a framework of tri-trophic interactions. This is a timely topic for research given the central role of caterpillars and plants in the ecology and trophic structure of terrestrial communities. This book is unique in that it contains chapters from a team of experts on a diversity of key topics within caterpillar-plant interactions. This volume brings together contributions by researchers from around the globe, working in both tropical and temperate habitats, and in human-managed and more natural habitats. It is a significant contribution to our understanding of insect biology, and the role that insects, as represented by caterpillars, play in a world increasingly dominated by humans and one in which threats to insect biodiversity are mounting.

Download or read book Alternate hosts of Blepharipa pratensis Meigen written by Paul A. Godwin and published by . This book was released on 1977 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: A current tactic for biological control of the gypsy moth, Lymantria dispar Linnaeus, is to release its parasites in forests susceptible to gypsy moth damage before the gypsy moth arrives. The basic assumption in these anticipatory releases is that the parasites can find and utilize native insects as hosts in the interim. Blepharipa pratensis is being used in this way. The efficacy of such releases has not been demonstrated. The present state of our knowledge about the niche requirements of gypsy moth parasites in general, and B. pratensis in particular, does not permit an evaluation now. However, we do have sufficient information to determine the crucial point of whether B. pratensis can live and develop in particular native lepidopteran species that are potential hosts. We report here on the survival of B. pratensis in eight potential North American hosts.
