Spinetoram
Spinetoram (marketed as Cheristin in its topical veterinary dosage-form) is an insecticidal mixture of two active neurotoxic constituents of ''Saccharopolyspora spinosa''. It is used to control pest insects in stored grain and on domestic cats. See also *Spinosad Spinosad is an insecticide based on chemical compounds found in the bacterial species ''Saccharopolyspora spinosa''. The genus ''Saccharopolyspora'' was discovered in 1985 in isolates from crushed sugarcane. The bacteria produce yellowish-pink ae ... References {{reflist Insecticides ...

Saccharopolyspora Spinosa
''Saccharopolyspora spinosa'' is a species of actinobacterium first isolated from soil in a rum still in an abandoned sugar mill on the Virgin Islands. It was discovered and described by researchers Mertz and Yao while collecting specimens to be screened for novel antibiotics. It develops aerial, pale, yellowish pink hyphae and bears long chains of spores encased in spiny spore sheaths. It can also reproduce by fragmentation in an aqueous environment. Its type strain is A83543.1 (= NRRL 18395). ''Saccharopolyspora spinosa'' is the source of a family of insecticidal compounds called spinosyns. They act as neurotoxins by activation of nicotinic acetylcholine receptors in insects. The insecticide Spinetoram is composed of two synthetic derivatives of spinosyns.

Insecticide
Insecticides are substances used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repellent ...

Spinosad
Spinosad is an insecticide based on chemical compounds found in the bacterial species ''Saccharopolyspora spinosa''. The genus ''Saccharopolyspora'' was discovered in 1985 in isolates from crushed sugarcane. The bacteria produce yellowish-pink aerial hyphae, with bead-like chains of spores enclosed in a characteristic hairy sheath. This genus is defined as aerobic, Gram-positive, nonacid-fast actinomycetes with fragmenting substrate mycelium. ''S. spinosa'' was isolated from soil collected inside a nonoperational sugar mill rum still in the Virgin Islands. Spinosad is a mixture of chemical compounds in the spinosyn family that has a generalized structure consisting of a unique tetracyclic ring system attached to an amino sugar (D-forosamine) and a neutral sugar (tri-''Ο''-methyl-L-rhamnose). Spinosad is relatively nonpolar and not easily dissolved in water. Spinosad is a novel mode-of-action insecticide derived from a family of natural products obtained by fermentation of ''S ...
