Bacillus thuringiensis (Bt) is a naturally occurring bacterium that can be commonly found. It is considered a highly beneficial bacterium as it is useful for controlling pests, for instance, Common Cutworm Plutella xylostella, Beet armyworm, Trichoplusia ni, Cotton bollworm, Lepidoptera- Moths Limacodidae. As Bt causes an adverse effect, specifically on larvae, it is nontoxic to people and warm-blooded animals, e.g., fish, birds and other beneficial pollinators like honeybees and wasps.
