What is Bacillus thuringiensis?
Bacillus thuringiensis (Bt) is a soil-dwelling bacterium that belongs to the same genus as Bacillus anthracis (the cause of anthrax) and Bacillus cereus (a common foodborne pathogen). However, unlike its cousins, Bt is harmless to humans, animals, and plants. Bt was discovered in 1901 by a Japanese biologist named Shigetane Ishiwata, who isolated it from diseased silkworms. Later, in 1911, a German entomologist named Ernst Berliner rediscovered it from dead flour moths and named it after the German town of Thuringia where he worked.
Bt produces spores and crystals that contain proteins called delta-endotoxins or Cry toxins. These toxins are specific to certain insects, such as caterpillars, beetles, flies, mosquitoes, and nematodes. When these insects ingest the spores and crystals, the toxins bind to receptors in their gut lining and create pores that cause cell death and gut paralysis. The insects stop feeding and die within hours or days.
How does Bacillus thuringiensis work as a biopesticide?
Bt works as a biopesticide by killing insects that damage crops or transmit diseases. Bt biopesticide products come in different forms, such as dusts, granules, liquids, or baits. They can be applied to the soil, foliage, seeds, or stems of plants or sprayed into the air or water. The mode of action and target pests of Bt biopesticide depend on the type and strain of Bt used.
There are over 200 different strains of Bt that produce different types of Cry toxins. Each type of Cry toxin has a specific affinity for certain insect groups. For example, Cry1 toxins kill lepidopteran insects (such as butterflies and moths), Cry2 toxins kill dipteran insects (such as flies and mosquitoes), Cry3 toxins kill coleopteran insects (such as beetles and weevils), and Cry4 toxins kill nematodes. Some Bt strains also produce other toxins, such as Cyt toxins, Vip toxins, or Sip toxins, that enhance the insecticidal activity of Bt.

You can also consult with experts or online resources to identify your pests and their characteristics.
Choose the right product. Once you know your pest problem, you need to choose the right Bt biopesticide product that matches your pest type and situation. You can read the product label or contact the manufacturer or supplier to find out the Bt strain, toxin type, formulation, concentration, shelf life, and compatibility of the product. You can also compare different products and their prices and reviews.
Apply at the right time. Timing is crucial when using Bt biopesticide. You need to apply it when your pests are most vulnerable and exposed to the product. For most pests, this is when they are in their larval stage and actively feeding on the plant tissue. You also need to consider the weather and environmental conditions that may affect the product performance and persistence.
Apply at the right rate. The rate of application refers to how much product you use per unit area or volume. You need to follow the instructions on the product label or package to determine the appropriate rate for your pest problem and situation. You also need to measure and calibrate your equipment and tools to ensure accurate and uniform application.
Apply at the right place. The place of application refers to where you apply the product on the plant or in the environment. You need to target the parts of the plant or the areas where your pests are feeding or hiding. You also need to cover as much surface as possible and avoid gaps or overlaps that may reduce the product coverage and efficacy.
Repeat as needed. One application of Bt biopesticide may not be enough to control your pest problem completely. You may need to repeat the application every few days or weeks until you achieve satisfactory results. You also need to monitor your pest situation and adjust your application frequency and rate accordingly.

It is compatible with organic farming and integrated pest management practices. It is certified by various organic standards and labels around the world. Q: How long does Bt biopesticide last?
the pest density and behavior, and the application method and frequency. Generally, Bt biopesticide lasts for a few days or weeks in the environment before it is degraded by UV rays, rain, wind, or microbial activity. However, some Bt biopesticide products may have longer shelf lives or residual effects depending on their formulation and storage. Q: Does Bt biopesticide kill bees?
A: No, Bt biopesticide does not kill bees. Bees are not susceptible to the toxins produced by Bt because they do not have the receptors in their gut lining that bind to the toxins. Bees are also not exposed to Bt biopesticide because they do not feed on the plant tissue or the product itself. Bt biopesticide is safe for bees and other beneficial insects, such as ladybugs, butterflies, or parasitoids. Q: Can pests develop resistance to Bt biopesticide?
A: Yes, pests can develop resistance to Bt biopesticide if they are exposed to it repeatedly and continuously over time. Resistance occurs when pests mutate or adapt to survive the exposure to Bt toxins and pass on their resistance genes to their offspring. Resistance can reduce the effectiveness of Bt biopesticide and increase the pest damage and control costs. To prevent or delay resistance, you need to use Bt biopesticide as part of an integrated pest management strategy that includes crop rotation, pest monitoring, biological control, cultural control, physical control, and chemical control. 71b2f0854b
