Insect Resistance In Field Crops

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