One of the successful agents used as insect pesticide is the bacterium,Bacillus thuringiensis.
Bacillus thuringiensis(Bt) is said to be more effective when its dusted on tobacco or other plants.The organism is recommended for use against tobacco budworms and hornworms.
From research,it is noted as a promising biological control.
Different strains of the bacterium target different insects; one strain can even kill mosquito larvae in water. Organic farmers dust or spray Bacillus thuringiensis on crops and consider it a natural insecticide. In conventional farming,Bacillus thuringiensis DNA is often inserted into a plant’s genome, creating genetically modified crops that make their own pesticide.
In 2015, 81 percent of U.S. corn and 84 percent of U.S. upland cotton contained Bacillus thuringiensis genes.
