This book comprehensively reviews current pest management practices and explores novel integrated pest management strategies in Brassica oilseed crops. It is essential reading for pest management practitioners and researchers working on pest management in canola and other Brassica crops worldwide. Canola, mustard, camelina and crambe are the most important oilseed crops in the world. Canola is the second largest oilseed crop in the world providing 13% of the world's supply. Seeds of these species commonly contain 40% or more oil and produce meals with 35 to 40% protein. However, its production has declined significantly in recent years due to insect pest problems. The canola pest complexes are responsible for high insecticide applications on canola. Many growers rely on calendar-based spraying schedules for insecticide applications. The diamondback moth Plutella xylostella and flea beetles Phyllotreta spp. (P. cruciferae and P. striolata)cause serious damage to canola. In the Northern Great Plains, USA, for instance, P. xylostella is now recorded everywhere that canola is grown. Severe damage to canola plants can be caused by overwintering populations of flea beetles feeding on newly emerged seedlings. Cabbage seed pod weevil (Ceutorhynchus obstrictus), swede midge (Contarinia nasturtii), and tarnished plant bug (Lygus lineolaris) are also severe pests on canola. Minor pests include aphids (cabbage aphid, Brevicoryne brassicae and turnip aphid, Hyadaphis erysimi) and grasshopper, Melanoplus sanguinipes.

The dominance of insects in the world fauna has made them the humanity's greatest rival for the world's food resources, both directly by eating the plants cultivated for food and indirectly as vectors of pathogens attacking these plants. Agricultural scientists and especially entomologists have strived hard to develop a diversity of cultural, mechanical, biological and chemical weapons during the last more than two centuries to gain dominance over insects. However, there is evidence that insect pest problems have escalated with an increasing cropping intensity and with the use of agrochemicals inherent in modern agriculture. Consequently, Indian plant protection scientists have intensified research on the development of pest management tactics and effective pest management systems have been designed for all the important crops in the country. This book, consisting of 29 chapters, draws together the diverse literature on the subject of insect pest management in agriculture and contains contributions written by scientists having extensive experience with insect pest problems in Indian agriculture. The first half of the book is devoted to the principles and components of pest management including factors affecting pest populations, construction of life tables, coevolution of insects and plants, pest forecasting, pesticides, IGRs, botanicals, entomopathogenic nematodes and molecular approaches, etc. The different tactics for the management of major insect pests of principal agricultural crops of India, viz. rice, maize, wheat, forage crops, cotton, sugarcane, vegetables, fruits, oilseeds, pulse crops, jute, mesta and tobacco have been discussed in the second half of the book. The book contains a wealth of information on all aspects of insect pest management in agriculture under Indian conditions and would prove indispensable for students, teachers and researchers in agricultural entomology in India and other Asian countries.

In the middle of the twentieth century, new insecticides were being con stantly developed and it seemed that pesticides would be able to control insect pests indefinitely. In fact, from the 1950s to the 1980s, pest control was mostly based on conventional insecticides such as organochlorines, organo phosphates, carbamates and pyrethroids. However, the severe adverse effects of pesticides on the environment, the resistance problems reaching crisis pro portions and public protests led to stricter regulations and legislation aimed at reducing the use of pesticides. Consequently, other ways to manage insects have been suggested, such as the use of biorational pesticides with minimal adverse effects on the environment, biological control, host-plant resistance to pests, mating disruption with pheromones, and cultural and physical con trol. The ideas behind "integrated control" were published at the end of the 1950s by groups of entomologists from California, and served as a basis for initiating integrated pest management (IPM) in the 1970s. Since the 1980s, insecticide resistant management (IRM) programs have been introduced as a result of increasing problems of resistance to pesticides. IPM programs were strengthened as the awareness of environmental fragility intensified. Since the late 1990s, advanced approaches to manage insect pests have been devel oped. One of the novel and exciting innovations in the study of plant resis tance to pests has been the introduction of genetically engineered or trans genic plants.

Oilseed rape is a major arable crop in both Europe and North America. It is attacked by unique complexes of insect pests still largely controlled through the application of chemical insecticides. Crop management systems for the future must combine sustainability with environmental acceptability to satisfy both social and economic demands. This book, in its 17 chapters each led by a world expert, reviews research progress towards developing integrated pest management systems for the crop that enhance conservation biocontrol. This approach is particularly timely because of the development in Europe of insecticide resistance in the pollen beetle, a major pest of the crop. The past decade has seen considerable progress in our knowledge of the parasitoids and predators that contribute to biocontrol, of their distribution patterns, and their behavioural ecology, both within and without the crop. There is potential for natural enemy conservation through modification of within-field crop husbandry practices, as well as, on the landscape scale, through habitat manipulation to encourage vegetational diversity. This book will prove invaluable as a text for researchers, university teachers, graduate scientists, extension workers and growers involved in integrated pest management.
