The pine processionary moth Thaumetopoea wilkinsoni Tams is a serious pest on pine trees in southwestern Turkey. The efficacy of a naturally derived insecticide, spinosad, on fourth‐fifth instar larvae of T. wilkinsoni was studied under laboratory conditions. The product exhibited strong larvicidal activity and at doses above 5 mg litre −1 caused >90% mortality in the fourth–fifth larval stages of the species after 72 h. At 72 h the LD 50 and LD 90 values were 3.26 and 5.69 mg litre −1 respectively. The results showed that spinosad is highly effective on T. wilkinsoni larvae.
