Bacillus thuringiensis(Bt) is aspore forming(flash animation)bacterium that produces crystals protein (cry proteins), which are toxic to many species of insects. Where is Bt found? Btcan be found almost everywhere in the world. Surveys have indicated thatBtis distributed in the soil sparsely but...
Bt (Bacillus thuringiensis): Bt is a naturally occurring soil bacterium that specifically targets bagworm caterpillars. When ingested, it causes the caterpillars to become sick, cease feeding, and eventually die. The best time to apply Bt is during the hatching period of young worms, typically in...
Bacillus thuringiensis is a type of bacteria that's found in the soil, the surface of some plants, and in the stomachs of some...
To date, insect resistance has been provided by a gene from the soil bacterium Bacillus thuringiensis(Bt). This gene directs cells to manufacture a crystalline protein that is toxic to certain insects but does not harm other organisms. The toxin gene in different strains of Bt can affect ...

In addition to products like biopharmaceuticals, biotechnology is used to manufacture specialty products like biopesticides for agricultural use. “Recent examples are Bacillus thuringiensis (BT) insect toxins (produced by Pfizer for Ecogen's biopesticide products) and azadirachtin derived from ...
The microbial insecticide Bacillus thuringiensis (Bt) kills caterpillars two to three days after they eat treated leaves. Mix 4 teaspoons of Bt concentrate per 1 gallon of water in a pressurized sprayer. Spray all the leaf surfaces until wet, but not to the point of runoff. Repeat the treatme...
