One of the main objective of biotechnology is to minimize the use of insectisides on cultivated crops. Explain with the help of a suitable example how insect resistant crops have been developed using techniques of biotechnology?

Insects resistant crops are developed using genetic engineering or recombinant DNA technology. This method involves the transfer of one or more genes(DNA fragments) from one plant to another. The plant in which foreign gene has been introduced is known as transgenic plant. So insect resistant crops are developed by introducing insect resistant gene into the crop plant.The introduction of gene occurs either by using vector, electroporation, microinjection etc.
