What is Bt Brinjal?
Bt Brinjal is a transgenic brinjal created by inserting a gene cry1Ac from the soil bacterium Bacillus thuringiensis into Brinjal. This is said to give the Brinjal plant resistance against lepidopteran insects like the Brinjal Fruit and Shoot Borer Leucinodes orbonalis and Fruit Borer Helicoverpa armigera.

Objective of developing genetically engineered Bt-brinjal
The objective of developing the genetically engineered form of brinjal, known as Bt-brinjal, is to make it pest-resistant.
Explanation
1. Pest resistance: Brinjal is highly susceptible to attack by pests, especially the fruit and shoot borer (FSB) insect. The FSB larvae bore into the fruits and shoots of the brinjal plant, causing significant damage to the crop. This leads to reduced yield and quality of brinjal. The genetic engineering of Bt-brinjal involves the insertion of a gene from the soil bacterium Bacillus thuringiensis (Bt) into the brinjal plant. This gene produces a protein toxic to FSB, making the Bt-brinjal resistant to this pest.
2. Reduction in pesticide use: By making the brinjal plant resistant to FSB, the Bt-brinjal reduces the need for chemical pesticides. Farmers typically use a significant amount of pesticides to control FSB infestation, which not only incurs additional costs but also poses environmental and health risks. The cultivation of Bt-brinjal can minimize the use of chemical pesticides, thereby promoting sustainable agriculture and reducing the negative impact on the environment and human health.
3. Increased yield: The pest-resistant nature of Bt-brinjal can result in increased crop yield. As the FSB infestation is controlled, the brinjal plants can grow healthier and produce more fruits. This can contribute to better agricultural productivity and economic benefits for farmers.
4. Improved food security: By reducing crop losses caused by FSB infestation, Bt-brinjal can contribute to food security. Brinjal is an important vegetable crop in many countries, and any significant damage to its yield can affect food availability and affordability. The development of pest-resistant varieties like Bt-brinjal helps in ensuring a stable food supply, especially in regions where brinjal is a staple food.
In conclusion, the objective of developing genetically engineered Bt-brinjal is to make it pest-resistant, thereby reducing the need for chemical pesticides, increasing crop yield, and improving food security.
