White powder Bacillus thuringiensis Insecticide for lepidopterous larvae control

White powder Bacillus thuringiensis Insecticide for lepidopterous larvae control

Description:

Bacillus thuringiensis, which is also called Bt, is an insecticide with stomach action.

Following ingestion, the crystals of endotoxin are solubilised; the epithelial cells of

the gut are damaged, insects stop feeding and eventually starve to death.

Bacillus thuringiensis (or Bt) is a Gram-positive, soil-dwelling bacterium, commonly

used as a biological pesticide. 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 and grain-storage

facilities.

During sporulation, many Bt strains produce crystal proteins (proteinaceous inclusions),

called δ-endotoxins, that have insecticidal action. This has led to their use as insecticides,

and more recently to genetically modified crops using Bt genes. Many crystal-producing

Bt strains, though, do not have insecticidal properties.

Applications:

Insecticide with stomach action. Following ingestion, the crystals of endotoxin are

solubilised; the epithelial cells of the gut are damaged, insects stop feeding and eventually

starve to death. Used for control of lepidopterous larvae in agriculture, horticulture

and forestry. Ecogen strain EG2424 is used for the control of Colorado potato beetle,

Leptinotarsa decemlineata. Formulation types OF; SC; WG; WP. Compatibility Compatible

with a number of acaricides, insecticides, fungicides, spreaders, stickers and wetters,

Specifications:

Active Ingredient
Common Name	Bacillus thuringiensis (Bt)
Chemical Name	Bacillus thuringiensis (Bt)
Pesticide Category	Insecticide
CAS No	68038-71-1
Properties	Composition Bacillus thuringiensis is an aerobic spore-forming gram-positive, rod-shaped bacterium, belonging to the family Bacillaceae. At sporulation, in addition to spores, crystals of protein, the delta-endotoxin, are also formed. Form Suspended solid in a fermentation broth or spray dried concentrate. S.g./density Depends on fermentation materials and procedure. Solubility Insoluble in water and organic solvents. Stability Damaged by u.v. light; dry powders stable up to 40°C; useful shelf life of aqueous concentrates 0.5 y (40°C), 1.0 y (21-25°C), >3 y (2-10°C); stable at pH 4 to pH 7 (20°C); alkaline hydrolysis: 100% in 1 h at pH 11-12.
Mode of Action	Insecticide with stomach action. Following ingestion, the crystals of endotoxin are solubilised; the epithelial cells of the gut are damaged, insects stop feeding and eventually starve to death.
Toxicity	Extensive studies on B. thuringiensis-containing pesticides demonstrate that isolates are not toxic or pathogenic. No adverse effects observed in body weight gain, clinical effects, or on necropsy. Infectivity/pathogenicity studies show that rodents gradually eliminate B. thuringiensis from the body after oral, inhalation or intravenous application. Observed toxicity at high doses is attributed to the vegetative growth stage, not to the insecticidal protein or to the spores. Early formulations, produced from B. thuringiensis subsp. thuringiensis contained a toxic b-exotoxin. See review by US EPA, J. T. McClintock et al., Pestic. Sci., 45, 95 (1995). Some data are given under individual subspp. Toxicity class EPA (formulation) III
