Spinosad is an insecticide based on chemical compounds found in the bacterial species Saccharopolyspora spinosa. The genus Saccharopolyspora was discovered in isolates from crushed sugarcane which 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 relatively new insecticide that is made up of two complex organic compounds, spinosyn A (right) and spinosyn D. These compounds are produced by certain microbes that were first discovered in soil found at an abandoned rum factory.
Spinosad is a broad-spectrum, organic insecticide. The term "broad-spectrum" means that it is toxic to a wide variety of insects. It is, however, relatively non-toxic to mammals and beneficial insects.
If used carefully only insects that actually eat something that has been treated, such as a leaf, are affected. This is different than a lot of other broad-spectrum insecticides that are toxic if the insect merely comes in contact with dry insecticide residues.
Spinosad is highly active, by both contact and ingestion, in numerous insect species.Its overall protective effect varies with insect species and life stage. It affects certain species only in the adult stage, but can affect other species at more than one life stage. The species subject to very high rates of mortality as larvae, but not as adults, may gradually be controlled through sustained larval mortality.The mode of action of spinosoid insecticides is by a neural mechanism.The spinosyns and spinosoids have a novel mode of action, primarily targeting binding sites on nicotinic acetylcholine receptors (nAChRs) of the insect nervous system that are distinct from those at which other insecticides have their activity. Spinosoid binding leads to disruption of acetylcholine neurotransmission.Spinosad also has secondary effects as a -amino-butyric acid (GABA) neurotransmitter agonist. It kills insects by hyperexcitation of the insect nervous system.Spinosad so far has proven not to cause cross-resistance to any other known insecticide.
