    Spinosad D is a new type of bio-insecticide, which has a unique chemical structure and is safe and quick-acting. It has won the "Presidential Green Chemicals Challenge Award" in the United States for its low toxicity, low residue and safety. Its mode of action is to stimulate the nervous system of insects, leading to non-functional muscle contraction and failure, accompanied by trembling and paralysis. It is consistent with the result that nicotinic acetylcholine receptor is activated, and it also acts on γ -aminobutyric acid receptor, which further promotes its insecticidal activity. Polysaccharide-based protein D is one of the main components of polysaccharide-based (HY-138800). Spinosad is a natural insecticide, which has biological activity against a series of insects including Lepidoptera.

Chemical property
    Light grayish white solid crystals with a slightly stale earthy smell. The vapor pressure is about 1.3×10-10Pa. In the aqueous solution with pH 7.74, it is relatively stable for metals and metal ions within 28 days. The half-life of photodegradation in soil is 9 ~ 10 days; The half-life of water photolysis is less than 1d. In the range of pH 5 ~ 7, it is relatively stable in aqueous solution; At pH 9, the half-life is > 200d d. Spinosad is a mixture containing more than ten components, the main components are A and D. The melting point of spinosad A is 84 ~ 99.5℃, the vapor pressure is 3.2×10-10Pa, and the solubility in water is 290mg/L(pH=5.0), 235mg/L(pH=7.0) and 16 mg/L (pH = 9.0), respectively. The distribution coefficients were 2.8, 4.0 and 5.2 at the corresponding pH values. Spinosad D has a melting point of 161.5 ~ 170℃ and a vapor pressure of 2.1×10-10Pa, and its solubility in water is 29mg/L(pH=5.0), 0.332mg/L(pH=7.0) and 0.053 mg/L (pH = 90.0) respectively. The distribution coefficients are 3.2, 4.5 and 5.2 respectively at the corresponding pH value.
