Milbemectin (1799297-76-9) is an allosteric agonist at the Drosophila RDL GABA receptor.1,2 Also acts as an agonist at glutamate-gated chloride channels in insects.3 Mutations (specifically a G326E substitution) in the glutamate-gated chloride channel 3 (GluCl3) in phytophagous mites abolishes agonist activity resulting in resistance.4 Commercially used as an acaricide.
