FAQs on BT Toxin Video Lecture - Biology Class 12 - NEET

1. What is BT toxin?
BT toxin, also known as Bacillus thuringiensis toxin, is a naturally occurring insecticide produced by the bacterium Bacillus thuringiensis. It is widely used in agriculture to control pests, particularly insects that damage crops.
2. How does BT toxin work?
BT toxin works by specifically targeting the digestive systems of insects. When ingested by the insect larvae, the toxin binds to specific receptors in their gut, causing the gut lining to break down. This leads to the release of toxic proteins that disrupt the digestive process, eventually resulting in the death of the insect.
3. Is BT toxin harmful to humans?
BT toxin has a long history of safe use in agriculture and is considered non-toxic to humans. It is highly specific in its mode of action, only affecting insects that have receptors for the toxin. The toxin is not active in the human digestive system, and studies have shown that it does not have any adverse effects on human health when consumed through food.
4. Can BT toxin harm beneficial insects?
While BT toxin is generally safe for beneficial insects, it can have some impact on certain groups, such as butterflies and moths. However, the impact is minimal when used according to recommended guidelines and proper application techniques. To minimize any potential harm, it is important to use targeted formulations and apply BT toxin during periods when beneficial insects are less active.
5. How is BT toxin used in agriculture?
BT toxin is commonly used in agriculture as a biopesticide. It is applied to crops in the form of sprays or as genetically modified crops that naturally produce the toxin. Farmers use BT toxin to control a wide range of pests, including caterpillars, beetles, and other insect larvae. Its use helps reduce the reliance on chemical pesticides, making it an environmentally friendly option for pest management.
