DOWNLOAD EBOOKThis 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 EBOOKMost 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 EBOOKFor 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 EBOOKScale 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.
