Description Main article
Insect resistant crop plants form the core component of Integrated Pest Management (IPM) due to their ability
to reduce the crop losses and associated insecticide costs in addition to protecting the environment. In this review,
various types of resistance being cited, resistance mechanisms and causal factors responsible with examples were
discussed. Traits associated with resistance, genetics and inheritance patterns were listed. Several sources of resistance
including crop varieties, wild relatives, QTLs identified and mapped for major insect pests so far were elaborated
along with steps in the development of a resistant variety. Advantages and limitations of insect resistance were also
discussed with emphasis on the development of insect biotypes. Novel strategies in molecular approaches like marker
assisted selection, gene pyramiding, RNAi approach along with genome editing strategies were emphasized. The
development of insect resistant crops is a sustainable way to manage pests and hence emphasis need to be given to
breed trait specific insect resistant cultivars utilizing the novel approaches in the future breeding programs.
