Bacillus Thuringiensis is a gram-positive aerobe bacillus which exists in soil and plants. It was discovered in 1902 in Japan and a few years later it was isolated in Thuringe (Germany). The effect it produces on larvae differs according to the selected kind. When Bacillus Thuringiensis sporulates, it produces some protein crystals called delta-endotoxins, which is responsible for its insecticide action. These protoxins must be ingested by larvae in order to start acting, as the selective toxicity of certain larva bacillus owes its action to two factors: in order to start acting these toxins need an alkaline ambience, which is only possible in the intestine of the majority of insects. These toxins can only act if they are united with specific receptors and this specificity depends on the insect.

Some insects are sensible to it, and some not.

When both factors are present the toxins quickly fasten onto its receptors and paralyze the intestine, stopping peristaltic activity, this way keeping the insect without alimentation. Besides, it breaks the epithelium of the intestine, allowing the access of the intestinal fluid to other vital organs and tissues of the insect. Just a few hours after ingesting a toxin spore, the jaws of the insect get paralyzed and its alimentation stops. Later on, the paralysis gets general, the reflex movements disappear and the larva dies.

Its action on agricultural pests is outstanding: Heliothis, Plusia, Plutella, Ostrinia, Capua, prays and Archips machlopis; as well as on forestall pests: Lymantrinia, Malacosoma, Euproctis and Tortryx viridiana.

Application: it can be applied through a regular pulverization unit, moistening well the plant and during the first stages of larva.
