Book Synopsis Species of Aphytis of the World by : David Rosen
Download or read book Species of Aphytis of the World written by David Rosen and published by Springer. This book was released on 1979-09-30 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great importance of accurate systematics for biological control has been pointed out and discussed time and again by numerous authors (see Clausen, 1942; Sabrosky, 1955; Schlinger and Doutt, 1964; Compere, 1969; Rosen and De Bach, 1973; DeBach, 1974; Delucchi, Rosen and Schlinger, 1976; and others) and does not require any further elaboration here. Suffice it to say that when natural enemies are being sought, or are transferred from one region to another in order to bring about biological control of an arthropod pest, correct identification of both the target pests and their natural enemies is an essential prerequisite for ultimate success. Failure in biological control has often resulted from inadequate systematics. This monograph, presenting a bio systematic revision of an important group of natural enemies, is therefore intended as a contribution to biological control as well as to basic science. The species of the genus Aphytis Howard (Hymenoptera: Cha1cidoidea: Aphelinidae) are minute, yellow or grayish wasps usually not exceeding one millimeter in length (see Figure I). They develop exclusively as primary ectoparasites of armored scale insects (Homoptera: Coccoidea: Diaspididae) and are the most important natural enemies of these serious pests. Armored scale insects are usually free beneath the hard covering scale or shield. The adult Aphytis female pierces the shield with the ovipositor and lays one to several eggs on the body of the scale insect.

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.
Book Synopsis Parasitoids in Pest Management by : Omkar
Download or read book Parasitoids in Pest Management written by Omkar and published by CRC Press. This book was released on 2023-03-13 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pests cause economic damage to crops and stored products, while vectors are responsible for the transmission of disease-causing agents in human beings and livestock. Although the application of synthetic pesticides in agriculture has given immediate relief, it has also caused well-known side effects, leading to a general consensus among entomologists and agriculturists to shift towards other ecofriendly pest management. Insect natural enemies consisting of predators, parasitoids, and pathogens have attracted the attention of scientists across the globe. These natural enemies exist in agroecosystems and suppress the populations of pests. Parasitoids are farmers’ friends and the most successful group of natural enemies. Highly specialised in their host choice, the female parasitoid searches for a suitable host to lay eggs and larvae in, on or near the hosts. Exploiting this potency of parasitoids may yield successful results in controlling notorious pests in an ecofriendly way. This book covers information on the important biocontrol agents effective in pest suppression. It starts with insect parasitic groups followed by specific groups of parasitoids. It is hoped that the book presents a comprehensive account of beneficial parasitoirds, and will be useful to undergraduate and postgraduate students of Entomology, Biological Control, Plant Protection, Agricultural Zoology, and Zoology, besides those involved in competitive examinations and policy planning. Features: Each chapter has been written by very experienced specialists Every chapter includes Learning Objectives and Points to Remember This book offers comprehensive knowledge of parasitoids and their application in pest management in a rational way

Available in PDF, EPUB and Kindle. Book excerpt: To Make A Spotless Orange is the story of science with a mission: the use of organisms to attack pests. Few states showed very little interest after the first commercial pesticides appeared in the late nineteenth century. In california alone, entomologists persevered in developing both the theory and practice of biological control. These entomologists were neither environmentalists nor health crusaders, but scientist s who believed that their method would be the cheapest and most effective in the long run.

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.
