This book discusses the biological control of weeds using arthropods, providing ecological management models for use across the tropical world.This book covers the origin, distribution, and ecology of twenty invasive tropical weed species, and their sustainable biological control using arthropods. The aim is to provide ecological management models for use across the tropical world, and to assist in the assessment of potential risks to native and economic plants.This book covers the origin, distribution, and ecology of twenty invasive tropical weed species, and their sustainable biological control using arthropods. The aim is to provide ecological management models for use across the tropical world, and to assist in the assessment of potential risks to native and economic plants.Weeds are a major constraint to agricultural production, particularly in the developing world. Cost-efficient biological control is a self-sustaining way to reduce this problem, and produces fewer non-target effects than chemical methods, which can cause serious damage to the environment. This book covers the origin, distribution, and ecology of twenty model invasive weed species, which occur in habitats from tropical to temperate to aquatic. Sustainable biological control of each weed using one or more arthropods is discussed. The aim is to provide ecological management models for use across the tropical world, and to assist in the assessment of potential risks to native and economic plants. This is a valuable resource for scientists and policy makers concerned with the biological control of invasive tropical plants.1. Biological control of weeds in the tropics and sustainability R.
