Spodoptera exigua is a major insect pest of vegetables in Shandong, China, and has been reported to develop resistance to many insecticides. The present study was carried out in 2011–2012 to evaluate the resistance ratios (RRs) to eight insecticides in S. exigua populations from five regions in Shandong. A standard leaf-dip method showed no resistance to chlorfenapyr (RR <2). RRs to emamectin benzoate, indoxacarb, and spinosyn were in the ranges of 3.00 to 37.4-fold, 8.63 to 84.1-fold, and 9.27 to 86.2-fold, respectively. S. exigua showed high resistance to the insect growth regulators (IGR) tebufenozide and methoxyfenozide. No resistance to the diamide insecticides chlorantraniliprole and flubendiamide was found. The insecticides chlorfenapyr, emamectin benzoate, indoxacarb, spinosyn, chlorantraniliprole, and flubendiamide had no, very low, low, and moderate resistance levels for most of the tested populations. Due to these characteristics they could be used in pest management programs supplemented with physical and biological control measures.
