Chemical inhibition of the proteasome system using the multiple myeloma treatment drug, PS-341 reduced loss of Dα6 in response to spinosyn A at the 20-min time point to 6.35%. In addition, in vivo administration of PS-341 prior to spinosad exposure reduced the effect of spinosad on larval activity. Based on these data, we propose that exposure to spinosad leads to degradation of the α6-like target protein, a potentially novel element in the mode of action of spinosyns that may contribute to their toxicity towards insects.
