Download or read book Biorational Control of Arthropod Pests written by Isaac Ishaaya and published by Springer Science & Business Media. This book was released on 2009-08-28 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nearly 50 years, pest control was mostly based on broad-spectrum conv- tional insecticides such as organochlorines, organophosphates, carbamates and pyrethroids. However, the severe adverse effects of pesticides on the environment, problems of resistance reaching crisis proportions and public protests led to stricter regulations and legislation aimed at reducing their use. Ways to reduce the use of synthetic pesticides in plant protection and to use more alternative and novel me- ods for pest control or biorational control are the challenges of pest control for the twenty-first century. The term biorational (biological + rational) pesticides can be defined as the use of specific and selective chemicals, often with a unique modes of action, that are compatible with natural enemies and the environment, with minimal effect on n- target organisms. Biorational control is based on a diversity of chemical, biological and physical approaches for controlling insect pests which results in minimum risk to man and the environment.
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.

Available in PDF, EPUB and Kindle. Book excerpt: Most basic information on plant-mealybug interactions during the last decade has come from research on the cassava Manihot esculenta Crantz (Euphorbiaceae) system with two mealybug species, namely Phenacoccus manihoti Matile-Ferrero and Phenacoccus herreni Cox and Williams (Sternorrhyncha: Pseudococcidae). Both these insects cause severe damage to cassava in Africa and South America, respectively. This book reviews these interactions (plant selection by the insects, nutritional requirements

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.

Download or read book Encyclopedia of Scale Insect Pests written by Takumasa Kondo and published by CABI. This book was released on 2022-06-15 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scale insects feed on plant juices and can easily be transported to new countries on live plants. They sometimes become invasive pests, costing billions of dollars in damage to crops worldwide annually, and farmers try to control them with toxic pesticides, risking environmental damage. Fortunately, scale insects are highly susceptible to control by natural enemies so biological control is possible. They have unique genetic systems, unusual metamorphosis, a broad spectrum of essential symbionts, and some are sources of commercial products like red dyes, shellac and wax. There is, therefore, wide interest in these unusual, destructive, beneficial, and abundant insects. The Encyclopedia of Scale Insect Pests is the most comprehensive work on worldwide scale insect pests, providing detailed coverage of the most important species (230 species in 26 families, 36% of the scale insect pest species known). Advice is provided on collection, preservation, slide-mounting, vouchering, and labelling of specimens, fully illustrated with colour photographs, diagrams and drawings.
