The higher acreage and low productivity in chickpea depends on number of constraints, among them insect-pest has been recognized as one of the constraints. Among various insect-pests of chickpea Helicoverpa armigera is one of the most important biotic constraint, the damage caused during flowering and pod formation stages results in substantial yield loss. Chickpea is most preferred host of H. armigera, and it suffers losses to the tune of 20-80 % The pest can be managed by spraying the insecticides at the economic threshold level. As such, some modern trends are aimed for finding effective but safer insecticides that can be used in conjugation with bio-agents (NPV, Bt.), botanical insecticides (NSKE, Azadirachtin) so as to regulate pest population within economic limit and In order to minimize the adverse consequences of the pesticides there is dire need to develop eco-friendly management practice for this pest, which could be done by studying the seasonal incidence of the pest on chickpea. In the present study both the aspects of managing Helicoverpa had been undertaken, so that in future we may develop an integrated approach towards management of this noxious polyphagous pest.

Heliothis ("Bull worm") species are one of the major pests of 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 comprehensive text, written by experienced researchers, assembles biological and ecological research techniques and approaches to Heliothis management: from the fundamental question of defining genetic species to collecting, rearing, and sampling techniques for the construction of life tables; the measurement of predator impact and physiological development; the detection and measurement of behavior, migration, and diapause; 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.

Plant based Biotechnology has come to represent a means of mitigating the problems of global food security in the twenty first century. Products and processes in agriculture are increasingly becoming linked to science and cutting edge technology, to enable the engineering of what are in effect, designer plants. One of the most successful, non chemical approaches to pest management and disease control, which seeks a solution in terms of using living organisms to regulate the incidence of pests and and pathogens, providing a `natural control' while still maintaining the biological balance with the ecosystem. This volume, describes the various biological agents used to control insect pests of a variety of crops. Readers may also be interested in Volume 1: Crop diseases, Weeds and Nematodes, published in December 2000, ISBN 0-306-46460-8.
