Researchers report                      the identification and characterization of an Orco family agonist, VUAA1, using the Anopheles gambiae  coreceptor (AgOrco) and other orthologues. These studies reveal that  the Orco family can form functional ion channels in                      the absence of an odor-binding OR, and in addition,  demonstrate a first-in-class agonist to further research in insect OR                      signaling. In light of the extraordinary  conservation and widespread expression of the Orco family, VUAA1  represents a powerful                      new family of compounds that can be used to disrupt  the destructive behaviors of nuisance insects, agricultural pests, and                      disease vectors alike...
