    Milbemectin is a mixture of the two most abundant analogs (30% Milbemycin A3 and 70% Milbemycin A4) produced by the soil bacterium Streptomyces hydroscopicus subsp. aureolarcrimosus.  Milbemectin is a highly selective and potent insecticide, nematocide and acaricide used in crop protection.  It also acts as an agonist of the RDL GABA receptor in Drosophila. 

    Milbemectin is soluble in ethanol, methanol, DMF and DMSO.  Poor water solubility.

    We also offer:

    • Milbemycin A3 (M057)
    • Milbemycin A4 (M059)
    • Milbemycin A4 oxime (M060)
    • Mibemycin oxime (M015)
    Mechanism of Action

    The primary targets are glutamate-gated chloride channels. They also  interact with insect RDL γ -aminobutyric acid (GABA) receptors but their mode of action is unknown.


    insects including mites (spider mites), nematodes including pinewood nematode (Bursaphelenchus xylophilus) and C. elegans.

    Plant Biology Applications

    Milbmectin is used as an agri-chemical for crop protection in soft fruits, citrus fruit, top fruit, aubergines and others to combat mites and leaf miners.

    Insect Biology Applications

    Milbemectin is a GABA inhibitor and can acts as an agonist of the RDL GABA receptor in Drosophila.
