Download or read book An Annotated Catalog of the Type Material of Aphytis Hymenoptera Aphelinidae in the Entomology Research Museum University of California at Riverside written by Serguei V. Triapitsyn and published by Univ of California Press. This book was released on 2008-11-18 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: An annotated catalog of type material of the genus Aphytis Howard (Hymenoptera: Aphelinidae) in the collection of the Entomology Research Museum, University of California, Riverside, California, USA (UCRC) provides information on 75 valid species. Curation of the UCRC Aphytis slide collection involved remounting 7,390 specimens from Hoyer's medium into Canada balsam (a single specimen per each slide). This included 7,292 specimens that were remounted, labeled, and databased and 98 specimens that were remounted and labeled but not databased (the types of the South African species received on loan from the South African National Collection of Insects, Plant Protection Research Institute, Pretoria, South Africa). Among these are 309 primary type specimens (i.e., holotypes, syntypes, lectotypes, and neotypes) belonging to 51 nominal species, 2,473 secondary type specimens (i.e., paratypes, allotypes, and paralectotypes) of various nominal species, and 4,608 nontype specimens of many species of Aphytis from more than 50 different countries. Numerous nomenclatural and other mistakes (such as improper or coded labeling) in the treatment of the type specimens of the Aphytis species are corrected; several primary types are returned to the appropriate depositories, and many remounted secondary types are donated to other major taxonomic collections of Aphelinidae. Lectotypes are designated for A. africanus Quednau, A. coheni DeBach, A. cylindratus Compere, A. equatorialis Rosen and DeBach, A. fisheri DeBach, A. holoxanthus DeBach, A. immaculatus Compere, A. lepidosaphes Compere, A. lingnanensis Compere, A. melinus DeBach and A. taylori Quednau.

Download or read book Iranian Entomology An Introduction written by Cyrus Abivardi and published by Springer Science & Business Media. This book was released on 2001-07-03 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: This major work presents the first comprehensive survey on entomological studies in Iran from prehistoric periods up to modern times. This concise collection and excerpts from the literature are complemented by over 130 color figures of superb quality showing insects and their habitats. Volume 1 Faunal Studies concentrates on the systematic taxonomy of Iranian insects. It also lists all members of Rhopalocera (butterflies) and four families of Heterocera (moths). An introductory chapter is reserved for basic information on the geography, vegetation and climate of Iran. Volume 2 Applied Entomology starts with a chapter on the history of entomology in Iran until current times. Several chapters cover agricultural aspects of entomology, such as destructive insects, biological control or cultivars exhibiting resistance to insect pests. Other chapters are on medical entomology, e.g. mosquito-, sandfly- or flea-borne diseases and human myiasis.

Available in PDF, EPUB and Kindle. Book excerpt: The explosive increase in the world's human population, with conse quent need to feed an ever-increasing number of hungry mouths, and the largely resultant disturbances and pollution of the environment in which man must live and produce the things he needs, are forcing him to search for means of solving the first problem without intensifying the latter. Food production requires adequate assurance against the ravages of insects. In the last three decades short-sighted, unilateral and almost exclusive employment of synthesized chemicals for insect pest control has posed an enormous and as yet unfathomed contribution to the degradation of our environment, while our insect pest problems seem greater than ever. Properly viewed, pest control is basically a question of applied ecology, yet its practice has long been conducted with little regard to real necessity for control, and in some cases, with little regard to various detrimental side-effects or long-term advantage with respect, even, to the specific crop itself. This book deals fundamentally with these questions. The development of pesticide resistance in many of the target species, against which the pesticides are directed, has occasioned an ever-increasing load of applications and complexes of different kinds of highly toxic materials. This has been made even more "necessary" as the destruction of natural enemies has resulted, as a side effect, in the rise to pest status of many species that were formerly innocuous. The application of broad-spec trum pesticides thus has many serious and self-defeating features.
Download or read book Scale Insects of Central Europe written by M. Kosztarab and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to the scientists whose professional devotion and accomplish ments in research on scale insects of the area made the compilation of this book possible. This book has two primary objectives: (1) to enable interested workers, who are not specialists of scale insects, to recognize and indentify these to families, genera and species; and (2) to provide information on the life cycle, host-plant range, natural enemies, geographical distribution, economic importance for each known species from Central Europe, and to provide a bibliography on each taxa covered. Scale insects are important pests of fruit and nut trees, forest vegetation, woody ornamentals, greenhouse and indoor plants. World-wide losses and increased production costs attributed to scale insects are estimated to reach $5 billion annually. It is difficult to recognize them because of their microscopic size and hidden habits. Identification of pest species enables plant growers to check appropriate reference sources for biological information and to select control methods.

Download or read book Agricultural Insect Pests of Temperate Regions and Their Control written by D. S. Hill and published by CUP Archive. This book was released on 1987-05-28 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is a companion to Agricultural Insect Pests of the Tropics and their Control (2nd Edition 1983) and, like the earlier book, it is designed as a source of reference about most of the major insect and mite pests of agricultural crops. These two volumes by the same author now present a world-wide coverage of the economically important insect pests of tropical and temperate agriculture. Students taking courses in entomology, agriculture, crop pest biology and crop protection, and professional workers concerned with identification and control of insect pests, will find this comprehensive account an indispensable handbook and source of reference.
Download or read book Theoretical Approaches to Biological Control written by Bradford A. Hawkins and published by Cambridge University Press. This book was released on 2008-10-14 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological control is the suppression of pest populations using predators, parasitoids and pathogens. Historically, biological control has largely been on a trial-and-error basis, and has failed more often than it has succeeded. However by developing theories based upon fundamental population principles and the biological characteristics of the pest and agent, we can gain a much better understanding of when and how to use biological control. This book gathers together recent theoretical developments and provides a balanced guide to the important issues that need to be considered in applying ecological theory to biological control. It will be a source of productive and stimulating thought for all those interested in pest management, theoretical ecology and population biology.
