    • Abstract

       

      Phytophagous insect incidence is a serious threat for reduction of crop productivity globally. There is anestimation of one fourth of crop is being destroyed by insects annually. Indeed, the development of insect resistantcrops is a great milestone in agriculture to increase crop yield and reduce pesticide dependency.Genetic engineering facilitates development of insect resistant crops by expressing bacterial delta-endotoxins andvegetative insecticidal proteins and other plant genes like lectins, protease inhibitors, etc. In addition, RNAinterference and genome editing through CRISPR Cas9 also provides new solutions for the development ofinsect-resistant crops. The resultant genetically modified crops showed resistance against lepidopteran, dipteran,homopteran and coleopteran insects. The insect-resistant crops have made a significant economic impactworldwide in terms of higher yield and low pesticide usage. In this review, we focus on different strategies fordeveloping transgenics against insect pest control by expressing different insecticidal proteins in crops.
