This book reviews and synthesizes the recent advances in exploiting
host plant resistance to insects, highlighting the role of
molecular techniques in breeding insect resistant crops. It also
provides an overview of the fascinating field of insect-plant
relationships, which is fundamental to the study of host-plant
resistance to insects. Further, it discusses the conventional and
molecular techniques utilized/useful in breeding for resistance to
insect-pests including back-cross breeding, modified population
improvement methods for insect resistance, marker-assisted
backcrossing to expedite the breeding process, identification and
validation of new insect-resistance genes and their potential for
utilization, genomics, metabolomics, transgenesis and RNAi. Lastly,
it analyzes the successes, limitations and prospects for the
development of insect-resistant cultivars of rice, maize, sorghum
and millet, cotton, rapeseed, legumes and fruit crops, and
highlights strategies for management of insect biotypes that limit
the success and durability of insect-resistant cultivators in the
field. Arthropod pests act as major constraints in the
agro-ecosystem. It has been estimated that arthropod pests may be
destroying around one-fifth of the global agricultural
production/potential production every year. Further, the losses are
considerably higher in the developing tropics of Asia and Africa,
which are already battling severe food shortage. Integrated pest
management (IPM) has emerged as the dominant paradigm for
minimizing damage by the insects and non-insect pests over the last
50 years. Pest resistant cultivars represent one of the most
environmentally benign, economically viable and ecologically
sustainable options for utilization in IPM programs. Hundreds of
insect-resistant cultivars of rice, wheat, maize, sorghum, cotton,
sugarcane and other crops have been developed worldwide and are
extensively grown for increasing and/or stabilizing crop
productivity. The annual economic value of arthropod resistance
genes developed in global agriculture has been estimated to be
greater than US$ 2 billion Despite the impressive achievements and
even greater potential in minimizing pest- related losses, only a
handful of books have been published on the topic of host-plant
resistance to insects. This book fills this wide gap in the
literature on breeding insect- resistant crops. It is aimed at
plant breeders, entomologists, plant biotechnologists and IPM
experts, as well as those working on sustainable agriculture and
food security.
