摘    要:用氰戊菊酯对来自阳谷的棉铃虫(YG)Heliothis armigera(Hubncr) 进行抗性晶系的筛选。在15代期间经过9代的室内选育,获得抗性品系(Fcn-R),抗性倍数高达2“3倍,筛选后F15代LD50值(24.1412μg/头)比筛选前F1代lD50值(0.2020μg/头)提高了119.5倍。对来自偃师的棉铃虫(YS)进行了连续两代单对筛选,得到敏感品系(Fen-S),敏感晶系的LD50值为0.0116μg/头,接近1983年东台敏感晶系的LD50值(0.0098μg/头)Fcn-R抗性晶系筛选前后分别测定了七种杀虫剂的剂量-死亡回归线,发现Fen-R抗性品系对溴氰菊酯LD50(Fen-R)/LD50(YG)=5.2X] 和氯氰菊酯(2.5X)具有一定程度的交互抗性;而对功夫菊酯(0.66X),氯菊酯(0.89x)、灭多威(0.74X)及久效磷(1.5x)没有交互抗性。氰戊菊酯加Pb的增效试验结果表明棉铃虫对氰戊菊酯的抗性主要是由于多功能氧化酶的代谢作用。毒理学资料还暗示抗性为多因子(基因)的。

关 键 词:棉铃虫  氰戊菊酯  抗性品系  抗药性

Abstract:A fenvalerate resistant strain (Fen-R) of cotton bollworm, Heliothis armigera (Hiibner), was obtained by laboratory selection of a strain (YG) collected from Yanggu County, Shandong Province in 1990 after nine selections with fenvalerate during fifteen generations, and exhibited about 2463-fold resistance to this insecticide as compared with a susceptible strain collected from Dongtai County, Jiangsu Province in 1983. The LD50 value (24.1412μg/larva) in F15 generation after selection increased to l19.5-fold as compared with the LD50 value (0.2020 μg/larva) of F1.A fenvalerate susceptible strain (Fen-S) was developed by selection of progenies that resulted from single-pair matings of cotton bollworm collected from Yanshi County,Henan Province, under conditions free of insecticides, and its LD50 was 0.0116 μg/larva, close to that of Dongtai susceptible strain in 1983. Dose-mortality regressions were estimated for seven insecticides applied to Ygstrain before selection treatments and to Fen-R strain, respectively. A spectrum of cross-resistance was detected to deltamethrin LD50(Fen-R)/LD50(YG).= 5.2X] andcypermethrin (2.5X), but no cross-resistance to cyhalothrin (0.66x), permethrin (0.87X), methomyl (0.74X), and monocrotophos (1.5x). The studies on synergism of fenvalerate+Pb in Fen-R strain showed that resistance was due principally to the metabolic (multiple function oxidase) mechanism. Toxicological data suggested that more than one factors (genes) were responsible for resistance to fenvalerate in Helio.Shis arrnigera (Hiibner).
