This book was released on 2013-03-08 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The protection of agricultural crops, forest, and man and his domestic animals from annoyance and damage by various kinds of pests remains a chronic problem. As we endeavor to improve pro duction processes and to develop more effective and acceptable tactics for achieving this protection, we must give high priority to all potentially useful techniques for the control and management of insects. Pest control is recognized as an acceptable and necessary part of modern agriculture. Methods employed vary greatly and tend to reflect compromises involving 3 determining factors: technological capability, economic feasibility, and social acceptability. How ever, these factors are also subject to change with time since each involves value judgments that are based on available information, cost, benefit considerations, the seriousness of the pest problem, and the political climate. Whatever method is chosen, energy resources continue to dwindle under the impact of increasing popu lation, and it is inevitable that greater reliance must be placed upon renewable resources in pest management. One alternative is the use of a pest management method that uses the energy of the pest's own biomass to fuel a self-perpetuating control system. The use of biological control agents for the control of pests has long been an integral part of the pest management strategy in crop production and forestry and in the protection of man and animals. The importance and unique advantages of the method are well recognized; numerous treatises deal with accomplishments and methodologies.

Download or read book Mealybugs and their Management in Agricultural and Horticultural crops written by M. Mani and published by Springer. This book was released on 2016-02-24 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of information on all basic aspects of mealybugs, as well as management strategies for mealybug species affecting different crop plants in different countries. It highlights the latest information on morphology, cytogenetics, taxonomy, molecular characterization, biology, damage, ecology, natural enemies, ant association, control measures, insecticide resistance and pheromones – essential aspects which will equip researchers to pursue further research on mealybugs. The book examines current trends in the management of mealybugs for a variety of agricultural and horticultural crops, forest plants and mulberry in different countries, while also addressing the negative effects of chemical control methods and presenting success stories of mealybug control that utilize their natural enemies. It offers a valuable guide for crop growers, government officials and other stakeholders in the industry, as well as researchers and students engaged in related research and development activities.

Download or read book Oriental Mealybug Parasitoids of the Anagyrini Hymenoptera Encyrtidae written by John S. Noyes and published by Oxford University Press, USA. This book was released on 1994 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the natural enemies used in insect pest control, the parasitic Hymenopterahave been the most successful. Within this group, the Encyrtidaeare one of six families that have been employed in this way. In the past 10 years, two species of encyrtids have been used successfully against two severe pests in agriculture in Africa, the cassava mealybug and the mango mealybug. Among the encyrtids, almost all species of the tribe Anagyrini are primary endoparasitoids of mealybugs and are thus of potential importance in biological control. Within this context, recognition of Oriental anagyrini species should greatly facilitate their future use in biocontrol. In this volume, the 20 genera belonging to the Anagyrini, known to occur in the Oriental region, are defined by means of a dichotomous key and brief generic diagnoses. Biology and use in biocontrol are summarized for every genus and identification keys to the known Oriental species are provided. All species are defined by means of illustrations and brief diagnoses or full morphological descriptions, with 65 species being described as new. The known distribution and host range for every species is also provided, together with an annotated citation list. Two substantial appendices summarize the worldwide use of Encyrtidae in classical biological control and the species recorded as parasitoids of mealybugs.
