Emamectin B1a is a semisynthetic derivative of avermectin B1a (Item No. 22000).{35148} It binds to GABAA receptors (Ki = 17.6 nM in rat brain membranes), including those containing ?1, ?2, or ?3 subunits (IC50s = 57, 210, and 49.8 nM for ?1?1?2, ?1?2?2, and ?1?3?2 subunits, respectively), and potentiates the GABA response.{35146} Emamectin B1a also binds to and inhibits glycine receptors (IC50 = 218 nM in rat spinal cord). Emamectin B1a induces mortality in 90% of S. exigua larvae in a diet incorporation assay at a dose of 1.067 ng/ml, which is approximately 1,500-fold more toxic than avermectin B1. It is effective against neonate S. eridania larvae in a foliage spray bioassay and when applied topically.
