What is Spinosad based on?
Chemical compound. 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.
How does Spinosad work?
Mode of action. 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.
How many forms of spinosyn are there?
Spinosyns occur in over 20 natural forms, and over 200 synthetic forms (spinosoids) have been produced in the lab. Spinosad contains a mix of two spinosoids, spinosyn A, the major component, and spinosyn D (the minor component), in a roughly 17:3 ratio.
What is the mechanism of action of spinosoid insecticides?
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.
How long does spinosad stay in the bin?
Spinosad residues are highly stable on grains stored in bins, with protection ranging from 6 months to 2 years. Ecotoxicology parameters have been reported for spinosad, and are:
Does Spinosyn A interact with insecticidal receptors?
Spinosyn A does not appear to interact directly with known insecticidal-relevant target sites, but rather acts via a novel mechanism. Spinosyn A resembles a GABA antagonist and is comparable to the effect of avermectin on insect neurons. Spinosyn A is highly active against neonate larvae of the tobacco budworm, Heliothis virescens, and is slightly more biologically active than spinosyn D. In general, spinosyns possessing a methyl group at C6 (spinosyn D-related analogs) tend to be more active and less affected by changes in the rest of the molecule. Spinosyn A is slow to penetrate to the internal fluids of larvae; it is also poorly metabolized once it enters the insect. The apparent lack of spinosyn A metabolism may contribute to its high level of activity, and may compensate for the slow rate of penetration.
Is Spinosad a good insecticide?

- Spinosad is low in toxicity to people and other mammals. However, if it gets on your skin or in your eyes it can cause irritation and redness. In one study, 28 dogs were fed low to moderate doses of spinosad. One dog that received a moderate dose vomited. No effects related to spinosad were observed in the other dogs. Spinosad is practically non-toxic to moderately toxic …
Research
- No. In multiple studies, animals were fed low to moderate amounts of spinosad in their diet for 1.5 to 2 years. No increased incidence of cancer was observed. Moreover, spinosad has not been found to alter or damage genes. As a result of these experiments, the EPA has classified spinosad as not likely to cause cancer. In one study, dogs were fed low doses of spinosad for one year. Ef…
Effects
- Scientists have also tested whether spinosad causes developmental or reproductive effects in rats and rabbits. In these studies, animals were fed low to moderate doses daily throughout their lives or during their pregnancies. Effects were only observed at the highest doses. These included lower body weights and effects to some organs. Abnormal vaginal bleeding, more difficult labor…
Risks
- The EPA limits the levels of pesticides, including spinosad, allowed on food. Due to this, it is unlikely that individuals would be exposed to spinosad at levels this high through their diet.
