168316-95-8 arochemical Biological Pesticides Spinosad Insecticide 48%SC
Spinosad is an insecticide, active by contact and ingestion; causes paralysis.
It is based on chemical compounds found in the bacterial species Saccharopolyspora
spinosa. It contains spinosyn A and spinosyn D.
The genus of Saccharopolyspora was discovered in 1985 by Lacey and Goodfellow,
who described isolates from crushed sugar cane 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, non-acid-fast actinomycetes with
fragmenting substrate mycelium. S. spinosa was isolated from soil collected inside
a non-operational 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 non-polar 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. spinosa. 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 an approximately 17:3 ratio.

For control of pest Lepidoptera (e.g. Ostrinia nubilalis, Helicoverpa zea, Trichoplusia ni,
Plutella xylostella, Spodoptera spp., Heliothis spp., Pieris rapae, Keiferia lycopersicella,
Lobesia botrana), thrips (e.g. Frankliniella occidentalis, Thrips palmi), flies (e.g. Liriomyza
spp., Ceratitis capitata), beetles (e.g. Leptinotarsa decemlineata) and grasshoppers in
cotton, row crops, vegetables, and fruits, at 4.8-36 g/hl. Also used for urban pest control
(e.g. Agrotis ipsilon, Spodoptera spp., Parapediasia teterella) in turf and ornamentals, for
structural control of drywood termites (e.g. Cryptotermes brevis, Incisitermes snyderi),
and for fire ant (Solenopsis spp.) control. Effective as a bait for fruit flies (Ceratitis spp.,
Bactrocera spp., etc) and some ants (Solenopsis spp.).Under development for use on
livestock animals for control of chewing and sucking lice (e.g. Linognathus vituli, Bovicola
ovis, Solenopotes capillatus) and flies (e.g. Haematobia irritans, Lucilia cuprina), and in
livestock premises for control of nuisance flies (e.g. Stomoxys calcitrans, Musca domestica,
H. irritans). Formulation types SC; WG.
