Brassica oilseeds comprise canola, mustard, camelina and crambe and are the most important oilseed crops in the world. Among these, canola is the second largest oilseed crop providing 13% of the world's supply. Seeds of these species commonly contain 40% or more oil and produce meals containing 35-40% protein. However, canola production has been in decline in recent years as a result of insect pest problems. These pest complexes often demand high insecticide application.

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...
