Toxic Effects of Spinosad on Predatory Insects [PDF]

Biological Control, 2002
Spinosad (Dow AgroSciences) is a mixture of tetracyclic-macrolide compounds produced by a soil actinomycete and has been classified as a bioinsecticide. Spinosad is highly active against Lepidoptera but is reported to be practically nontoxic to insect natural enemies.

Optimization of spinosad production by Saccharopolyspora spinosa YJY-12 and its application in controlling Eggplant Thrips [PDF]

Scientific Reports
In this study, a new isolated strain YJY-12 with high yield of spinosad was isolated and its fermentation conditions for spinosad production was optimized. It was preliminary identified by morphological and molecular biology analysis to be S. spinosa YJY-

Enhanced spinosad production in Saccharopolyspora spinosa by employing mannose as an extracellular carbon reservoir and optimizing acetyl-CoA supply pathway [PDF]

Synthetic and Systems Biotechnology
Spinosad, a potent broad-spectrum insecticidal polyketide produced by Saccharopolyspora spinosa, faces limitations in industrial-scale production due to inherent inefficiencies in its native biosynthetic pathways.

Insecticidal Evaluation of Spinosad Against the Hide Beetle, Dermestes maculatus DeGeer (Coleoptera: Dermestidae) [PDF]

Insects
Spinosad, Saccharopolyspora spinosa, is widely used as a stored product protectant. However, its efficacy against the hide beetle Dermestes maculatus DeGeer (Coleoptera: Dermestidae), a major pest of dried animal-based materials, remains underexplored ...

Investigating zeta‐cypermethrin resistance stability in California Drosophila suzukii populations [PDF]

Pest Management Science, Volume 82, Issue 7, Page 6808-6816, July 2026.
After continuous selection and removal of selection pressure in spotted‐wing Drosophila, zeta‐cypermethrin resistance remained stable over several generations. Following a population bottleneck, zeta‐cypermethrin resistance increased without selection, highlighting the importance of insecticide rotation.

Improving spinosad production by tuning expressions of the forosamine methyltransferase and the forosaminyl transferase to reduce undesired less active byproducts in the heterologous host Streptomyces albus J1074

Microbial Cell Factories, 2023
Background Spinosad is a macrolide insecticide with the tetracyclic lactone backbone to which forosamine and tri-o-methylrhamnose are attached. Both the sugar moieties are essential for its insecticidal activity.

Expression of xenobiotic metabolizing cytochrome P450 genes in a spinosad-resistant Musca domestica L. strain. [PDF]

PLoS ONE, 2014
Spinosad is important in pest management strategies of multiple insect pests. However, spinosad resistance is emerging in various pest species. Resistance has in some species been associated with alterations of the target-site receptor, but in others ...

THE ABILITY OF COTTON LEAFWORM, Spodoptera littoralis (BOISD.) FIELD STRAIN TO DEVELOP RESISTANCE TOWARD SOME CONVENTIONAL AND BIO-INSECTICIDES [PDF]

Journal of Plant Protection and Pathology, 2009
This study aim to investigate the development of resistance in cotton leaf worm (CLW) to spinosad and abamectin comparing with the development of resistance toward cypermethrin and methomyl as conventional insecticides.

New insights on the effects of spinosad on the development of Helicoverpa armigera

Ecotoxicology and Environmental Safety, 2021
Helicoverpa armigera (cotton bollworm) is one of the most destructive pests worldwide. Due to resistance to Bacillus thuringiensis and conventional insecticides, an effective management strategy to control this pest is urgently needed.
