Question

(ii) Many crop farmers try to prevent insects such as aphids from damaging their plants.

Describe how modern technology is used to reduce damage to crop plants by insects.

Answer 1

Genetic engineering facilitates the development of insect resistant crops by expressing bacterial δ-endotoxins and vegetative insecticidal proteins and other plant genes like lectins, protease inhibitors, etc

Step-by-step explanation:

Plant pathogens, insects, and weed pests devastate over 40% of all possible sustenance creation every year. This loss happens despite utilizing approximately 3 million tons of pesticide per year in addition to the use of a variety of nonchemical controls such as biological controls and crop rotations.

If some of this food could be saved from pest attacks, it could be utilized to bolster an excess of 3 billion people who are malnourished in the world today.

In addition, RNA interference and genome editing through CRISPR Cas9 also provide new solutions for the development of insect-resistant crops.
