Spinosad is a natural insecticide. 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.
Studies to determine the acute toxicity of spinosad under laboratory conditions were conducted to generate LD50 or LC50 values. for oral and contact routes of administration. These demonstrated that spinosad was highly toxic to worker honeybees under worst. case laboratory conditions. Residue tests conducted under laboratory conditions using worker honeybees exposed to treated foli-. age, indicated that dry product residues were harmless.
