Solution
The correct option is D Boll worms
The correct option is D.
Explanation of Correct option:
- Bacillus thuringiensis secrete a protoxin called crystalline (Cry) protein.
- Once ingested by a target insect, the Cry protein gets activated which leads to the binding of it to the specific receptors located in the insect midgut epithelial cells creating pores that eventually lead to the death of the insect.
- The cotton bollworm is regulated by the proteins encoded by genes cry I Ac and cry II Ab.
- Nematodes, flies, and mosquitoes can be killed using pesticides and drugs.
Final answer: Cry 1 endotoxins obtained from Bacillus thuringiensis are effective against Boll worms.
