Bacillus thuringiensis subsp. kurstaki (Btk) is a group of bacteria used as biological control agents against lepidopterans (moths and butterflies). Btk, along with other B. thuringiensis products, is one of the most widely used biological pesticides due to its high specificity; it is effective against lepidopterans, and it has little to no effect on nontarget species.
Calosoma is a genus of large ground beetles that occur primarily throughout the Northern Hemisphere, and are referred to as caterpillar hunters or caterpillar searchers. Many of the 167 species are largely or entirely black, but some have bright metallic coloration. They produce a foul-smelling spray from glands near the tip of the abdomen.
Some microbes have been marketed for decades, such as Trichoderma fungi that suppress other, pathogenic fungi, and the caterpillar killer Bacillus thuringiensis. Serenade is a biopesticide containing a Bacillus subtilis strain that has antifungal and antibacterial properties and promotes plant growth. It can be applied in a liquid form on ...
Evidence of this fungus can be seen when small brown stems push through the forest floor: underneath will be the dried remains of the host caterpillar. [3] This species was first thought by Europeans to be a worm or caterpillar that burrowed from the top of a tree to the roots, where it exited and then grew a shoot of the plant out of its head. [4]
Mythimna separata, the northern armyworm, oriental armyworm or rice ear-cutting caterpillar, is a moth of the family Noctuidae.

[1] The species was first described by Francis Walker in 1865.

Lonomia obliqua is a species of saturniid moth ("giant silk moth") from South America. [1] It is famous for its larval form, rather than the adult moth, primarily because of the caterpillar's defense mechanism, urticating bristles that inject a potentially deadly venom.
The M44 was invented in the 1960s to replace a similar device known as a 'Coyote Getter', which had been in use since the 1930s. The Coyote Getter used a .38 Special pistol cartridge case to contain the sodium cyanide mixture, and ejected the cyanide with a primer.
