Name the pest that destroys the cotton bolls. Explain the role of Bacillus thuringiensis in protecting the cotton crop against the pest to increase the yield.
Answers
Hi there,
Answer: B.thuringiensis.
B.thuringiensis is the gram-positive bacterium which helps to protect the Crops of Cotton against the pest. The pest gets destroyed when the gene of this Bacterium ingested by the pest due to the toxicity. It is used as a pesticide, and it is first discovered by the Japanese Biologist.
Hope it helps you.
The name of the pest which destroys the cotton balls is BOLL WORM.
Explanation:
“Bacillus thuringiensis” is a majorly “distributed soil bacterium” and which is used for isolation from the soil, “litters and dead insects”. It is a spore forming bacterium which produces many toxins. “Spores of this bacterium produce the insecticidal Cry protein”.
Therefore this bacterium spores kills larvae of insects which attack the cotton balls.
When the pest ingest the protein, due to entry of cry protein which is toxic, the larvae gets killed and thus the yield is increased.
