| 为明确草地贪夜蛾对小麦的产卵选择性及其是否对小麦安全生产构成威胁,本研究以玉米和小麦作为测试寄主,比较分析了草地贪夜蛾对两种作物不同部位的产卵选择性,并利用两性生命表方法研究了取食小麦、玉米对其生命参数的影响。结果表明:草地贪夜蛾更喜欢在玉米上产卵,其在玉米、小麦叶片、玉米和小麦茎秆上的产卵量存在显著差异( df =102, F =15.593, P <0.05),以玉米叶片背面卵块数量(7.11±1.55)块/笼最高;草地贪夜蛾取食小麦可以完成生活史,但幼虫存活率、化蛹率、羽化率和世代存活率低于取食玉米。取食玉米的幼虫发育历期为(16.31±0.15)d,显著高于取食小麦的(14.66±0.12)d,蛹期、蛹重、产卵前期、成虫寿命和世代周期无显著差异。取食小麦羽化出的雌虫寿命、平均单雌产卵量显著高于取食玉米,分别为(16.39±0.40)d、(976.31±57.21)粒和(14.64±0.32)d、(831.57±30.55)粒。生命表参数显示取食玉米的净增殖率为363.14,显著高于小麦的258.63,但内禀增长率、周限增长率和平均世代周期无显著差异。研究结果为草地贪夜蛾在小麦上的预测预报和有效防控提供了基础数据。 |

| In order to clarify the oviposition preference of Spodoptera frugiperda and whether it poses a threat to the safe production of wheat. Maize and wheat were used as test hosts to compare and analyze the oviposition preference and the age stage two sex life table was used to obtain life table parameters of S. frugiperda feeding on maize and wheat. The results showed that S. frugiperda preferred to lay eggs on maize, and there were significant differences in the amount of eggs laid on maize, wheat leaves and stalks ( df =102, F =15.593, P <0.05). The egg masses on the opposite side of maize leaves was the highest, which is (7.11±1.55) masses per cage. The survival rate of larvae, pupa, adult and whole generation that fed on wheat were lower than those on maize. The period of larvae stage (16.31±0.15)d feeding on maize was significantly longer than that of on wheat (14.66±0.12)d. There was no significant difference in periods of pupa, preoviposition, and generation period as well as the pupa weight and adult longevity. The longevity of female and mean eggs laid per female feeding on wheat ［(16.39±0.40)d, (976.31±57.21) eggs］ were significantly higher than those of on maize ［(14.64±0.32)d, (831.57±30.55) eggs］, respectively. The parameters of life table showed that net reproductive rate (363.14) of S. frugiperda fed on maize was significantly higher than that on wheat (258.63). The intrinsic rate of increase, finite rate of increase， mean generation period of S. frugiperda fed on maize showed no significant difference compared to those on wheat. The results provide basic data for prediction and effective control of S. frugiperda on wheat. |
