Heliothis: Research Methods and Prospects

Heliothis ("bull worm") species are one of the major pests of the field crops worldwide, including sorghum, tomatoes, lettuce, and cotton. Pest problems have intensified over the years as the total area given to agricultural host plants has increased. This text, written by experienced researchers, assembles biological and ecological research techniques and approaches to Heliothis management. Topics discussed include the fundamental question of defining genetic species, collecting, rearing, and sampling techniques for the construction of life tables, the measurement of predator impact and physiological development, the detection and measurement of behaviour, migration, and diapause, and population genetics and resistance. Approaches to modelling population dynamics are also explored. This book is intended for beginning research students as well as experienced workers. It will be a valuable reference for entomologists, population ecologists, and agronomists concerned with crop protection.
