Solution:
1. What is Bacillus Thuringiensis?
Bacillus thuringiensis (BT) is a naturally occurring bacterium widely used as a biological control agent for pest management in agriculture. It produces proteins called Cry toxins that target specific insect pests, making it an effective alternative to chemical pesticides.
2. What is the full form of BT?
The full form of BT is Bacillus thuringiensis.
3. What is the role of BT?
The role of BT is to control insect pests that damage crops and transmit diseases. It acts as a natural insecticide by producing Cry toxins that selectively target and kill specific insect pests while minimizing harm to beneficial insects, animals, and the environment.
4. What are examples of Bacillus Thuringiensis?
Some examples of Bacillus thuringiensis strains include Bt kurstaki, Bt israelensis, and Bt tenebrionis. Each strain produces specific Cry toxins that target different insect pests, providing effective pest control solutions.
5. How does BT work?
BT works by producing Cry toxins that are toxic to susceptible insect pests. When ingested, the toxins bind to specific receptors in the insects' gut lining, forming pores that disrupt the gut cells. This leads to a loss of appetite, impaired digestion, and eventually, death of the insect.
6. Is BT organic?
Yes, BT is considered organic. It is an approved substance for organic farming practices. Its target-specific nature, minimal impact on non-target organisms, and its ability to break down naturally in the environment align with the principles of organic agriculture.
7. Why is BT toxin not toxic to humans and animals?
BT toxins are not toxic to humans and animals because they specifically target certain insect pests. The receptors that Cry toxins bind to are not present in the gut lining of humans and most animals, ensuring their safety. BT has been extensively studied and proven to be non-toxic to humans and animals when used as directed.
