Book Description
This monograph on pest slugs and snails reviews the problems they create as plant pests in horticulture, agriculture, and forestry, and also as intermediate hosts for parasitic trematodes, cestodes and nematodes which cause worm diseases in man and domestic animals. Here only those vector snails which inhabit flooded or constantly irrigated fields, water storage reservoirs or farm ponds are considered. Reference is also made to the role of pulmonates as carriers of the agents of disease - viruses, bacteria, fungi and worms' eggs, which may be transmitted to man with inadequately cleaned vegetables and fruit. The use of molluscs as indicators of chemical pollution of soil and water, methods of mass rearing of experimental animals and also marking methods are all discussed, as are threshold limit, critical number and the prognosis of damage in plant protection. A classification, an identification key and a systematic check-list of both pest slugs and snails and their predators are provided. The book reviews the biology, physiology, metabolism, reproduction and dispersal of freshwater and terrestrial gastropods, and also the ecological factors which allow a population explosion to occur, thus increasing the likelihood of damage to crops, or the spread of worm diseases of man and domestic animals. The interaction of parasitic worm larvae and their snail hosts is also discussed. These aspects all form an essential basis for the resolution of problems of control.

Book Description
Gardening YouTube sensation Huw Richards shows how to inexpensively grow year-round vegetables from just one raised bed. Keyed to a temperate coastal climate but adaptable to variations in temperature and rainfall, Huw's clear, practical advice will help you produce a bountiful harvest with minimal space and effort. In just one raised bed, green thumb wunderkind Huw Richards shows you how to grow vegetables easily, organically, abundantly, and inexpensively so you have something to harvest every month of the year. Month by month, discover what you need to do and how to do it. Try it in your yard, a small garden, or even on a roof terrace. Everything is explained in clear, photographed steps: building your bed, growing from seed, planting, feeding, and harvesting. Huw shows how to guarantee early success by starting off young plants on a windowsill. He suggests what to grow in each part of the bed and provides alternative vegetables to swap in or out depending on what you like eating. No-dig gardening methods remove most of the back-breaking work, too. Veg in One Bed goes beyond the inspiring demonstrations on his YouTube channel Huw's Nursery. In this book, he organizes all of his ideas and suggestions into a blueprint for growing your own vegetables month by month. Very little growing experience? Only a small space? No matter--with Veg in One Bed, you can still eat food you have grown throughout the year.

Book Description
In recent years slugs have become increasingly important, partly because several species are agricultural and horticultural pests and partly because theyhave proved to be useful experimental animals, particularly in the field of neurophysiology. Most of the early works which included slugs were essentially taxonomic but the book byTaylor (1902-1907) contained a great deal of biological information about slugs, some of which is still relevant today. The publication of the book by Runham and Hunter (1970) represented a milestone in slug research, providing a comprehensive survey of current knowledge about slugs. The book by Godan (1983) on snailsand slugswas mainly concerned with theeconomic importanceof theseanimals. The purpose of the present book is to present a review of current knowledgeofthebiologyandecologyofslugs, togetherwith theirstatusand control as pests. Although relatively little is known about the biology and ecology of tropical slugs and most information is taken from work on European slugs, the European pest species have become widely distributed throughout temperate regions and this book should be of interest world wide. It is written as a source of information for people seeking to control slug pests and, also, for those wishing to use slugs for research or teaching purposes. The book is intended particularly to provide a starting point for those beginning research on slugs and an extensive bibliography has been provided.
