【摘要】 就有关甜菜夜蛾Spodoptera exigua(Hbner)对常用杀虫剂的抗药性现状作综述。甜菜夜蛾对拟除虫菊酯类、有机磷类、氨基甲酸酯类杀虫剂已产生了较高水平的抗药性,其中山东泰安抗性种群对氯氟氰菊酯的抗性高达2445.5倍;对多杀菌素等生物杀虫剂产生了中低水平的抗性;对昆虫生长调节剂如虫酰肼的敏感性也有所降低,但昆虫生长调节剂依然是比较理想的防治药剂。对交互抗性及抗性治理也作了阐述。更多还原

【Abstract】 We summarized the status of resistance of beet armyworm, Spodoptera exigua (Hübner) to the insecticides commonly used in China. S. exigua developed high resistance to pyrethroid, organophosphorus and carbamate insecticides. One resistant strain of S. exigua from Tai’an region of Shandong Province, had 2 445.5-fold resistance to cyhalothrin. S. exigua developed low or medium level of resistance to bioinsecticides, for example, spinosad. Reduced susceptibility to insect growth regulator tebufenozide has been found, although insect growth regulator insecticide was still the favorable pesticide to control S. exigua. Cross resistance and resistance management were also reviewed in this paper.更多还原
