Bacillus thuringiensis - Wikipedia
WEBBacillus thuringiensis (or Bt) is a gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide. B. thuringiensis also occurs naturally in the gut of caterpillars of various types of moths and butterflies , as well on leaf surfaces, aquatic environments, animal feces, insect-rich environments, and flour mills ...
Bacillus thuringiensis (Bt) | Britannica
WEBBacillus thuringiensis (Bt), soil-dwelling bacterium that naturally produces a toxin that is fatal to certain herbivorous insects. The toxin produced by Bacillus thuringiensis (Bt) has been used as an insecticide spray since the 1920s and is commonly used in organic farming. Bt is also the source.
Bacillus thuringiensis ( Bt ) Fact Sheet - NPIC
WEBBacillus thuringiensis (Bt) in Brief. This fact sheet describes Bt used as a pesticide in sprays, granules, and other products. Bt crops are different. They're called "genetically engineered" or "transgenic" crops because they use DNA from Bt bacteria.

WEBWhat is Bacillus Thuringiensis (Bt) and How Does it Work? A natural microbe found in the soil, Bacillus thuringiensis produces proteins that are toxic to young, immature insects (or larvae). There are countless types of Bt, each targeting different groups of insects.
100 Years of Bacillus thuringiensis: A Critical Scientific Assessment
WEBABSTRACT. The insecticidal proteins produced by Bacillus thuringiensis (Bt) have provided a uniquely specific, safe, and effective tool for the control of a wide variety of insect pests. Bt has been used in spray formulations for over 40 years, where it is considered remarkably safe, in large part because specific formulations harm only a ...
Bacillus Thuringiensis - an overview | ScienceDirect Topics
WEBBacillus thuringiensis (Bt) is a group of strains or isolates of naturally occurring soil bacteria which mainly exerts toxicity through the production of Crystal (Cry) toxins. Cry toxins are used worldwide as aerial sprays or in transgenic plants to control disease-vector insect and crop pest populations.
