Usually referred to as “BT” is a naturally occurring bacterium that is lethal to most leaf-eating caterpillars on trees, shrubs, flowers, and vegetables. There are also varieties designed to kill mosquitoes or potato beetles. Bt is harmless to all other insects, animals, and humans. It comes in powder form for use as a dust or, diluted with water, [..]

A bacterium that produces a protein crystal that damages the gut of insects (mostly caterpillars), formulations of which are used as insecticides.

Biological insecticide that kills caterpillars but is harmless to the environment and higher warm blooded animals.

A bacterium used as a biological control agent for many insect pests; primarily mosquitoes, fungus gnats, and caterpillars. Take a look at Mosquito Dunks.

A bacterium that causes disease in many insects, especially caterpillars; formulations of the bacteria are used as insecticides.

A soil bacterium that produces toxins that are deadly to some pests. The ability to produce Bt toxins has been engineered into some crops. See Bt crops. Biopharming: The production of pharmaceuticals [..]

A soil microorganism that is used as a biological insecticide by farmers—including organic farmers—to control pests. Additionally, the cry gene from this microorganism has been engineered into some crops to confer insect resistance.

a soil bacterium that produces toxins against insects (mainly in the genera Lepidoptera, Diptera and Coleoptera). Bt preparations are used in organic farming as an insecticide, but such sprays show fu [..]

A species of Gram-Positive Bacteria which may be pathogenic for certain Insects. It is used for the biological control of the Gypsy Moth.

A species of gram-positive bacteria which may be pathogenic for certain insects. It is used for the biological control of the Gypsy moth.

A naturally occurring bacterium present in soil and used successfully by home gardeners and organic farmers to control certain insects for more than 40 years.  When ingested by a target insect, the protein produced by Bt

A species of soil bacterium that possesses genes for a group of insecticides, the Bt toxins. Different strains of the bacterium produce different Bt toxins. Some organic farmers use this bacterium as an alternative to using chemicals to control pest insects. The genes for Bt toxins have been genetically engineered into cotton plants so the plants p [..]

(Bt)

A bacteria that has been isolated from the soil that is used as an insecticide.  The pests must ingest this bacterium in order for it to kill the insect. There are different varieties of Bt commercial [..]

A large aerobic gram-positive or gram-variable bacillus that produces endospores. It produces a crystalline protein body pathogenic for the larvae of Lepidoptera. It is used as a biological insecticid [..]

A species of soil bacterium that possess genes for a group of insecticides, the Bt toxins. Different strains of the bacterium produce different Bt toxins. Some organic farmers use this bacterium as an alternative to using chemicals to control pest insects. The genes for Bt toxins have been genetically engineered into cotton plants so that the plant [..]

A naturally occurring bacterium with pesticidal properties. Bacillus thuringiensis produces a protein (Bt toxin) that is toxic only to certain insect larvae that consume it.

A bacterium that kills insects; a major component of the microbial pesticide industry.

A bacterium used as a biological control agent for many insect pests; primarily mosquitoes, fungus gnats, and caterpillars. Take a look at Mosquito Dunks.
