| 摘 要： | 为了阐明旱地胡麻对亚麻象蛀食胁迫的补偿效应,采用大田罩网法和伤口模拟危害法,结合田间调查分析和数据验证,研究亚麻象危害与胡麻产量及其相关性状补偿效应的相互关系,建立数学模型,模拟胡麻产生补偿效应的虫口密度范围。结果表明,虫口密度在20头/m2时,千粒重、单株产量和小区产量的补偿系数最高,分别为17.74%、24.62%和26.97%。亚麻象危害指数和千粒重的模拟回归方程为y=-0.1981x2+0.9029x+6.0766（R2=0.8090）,种群密度与危害指数模拟回归方程为y=0.0203x+0.4127（R2=0.9967）,亚麻象种群密度与胡麻产量模拟方程为y=-0.0051x2+0.7277x+86.107（R2=0.8814）。通过验证试验,对千粒重和产量的实测值与理论值进行Bonferroni配对比较的显著性检验,实测值与理论值差异不显著,拟合度较好。

| Abstract: | Ceuthrrhynchus liupanensis is a kind of boring insect, and compensatory response can be induced by boring stress of Ceuthrrhynchus liupanensis . The oil-flax has developed an important mechanism to adapt the boring stress, but there is a lack of relevant research. We aim to reveal the compensation effect of oil-flax yield traits under the boring stress of Ceuthrrhynchus liupanensis . A plot experiment was conducted to study the relationship between compensation effect of oil-flax and pest damage in different pest population density and wounds simulation test. The regression model was established to simulate the compensatory effect of oil-flax by using field investigation and data validation and the population density ranges of Ceuthrrhynchus liupanensis. Results showed that compensative coefficient was the highest at 20/m2 , for 1000-seed weight, yield per plant and plot yield, the compensative coefficients were 17.74%, 24.62% and 26.97% respectively. The regression equation between damage index and 1000-seed weight was y=-0.1981x2+0.9029x+6.0766（R2=0.8090）, the regression equation between population density and damage index was y=0.0203x+0.4127（R2=0.9967）, regression equation between population density and yield was y=-0.0051x2+0.7277x+86.107（R2=0.8814）.The test of significance showed that measured value and theoretical value had no significant difference, the goodness of fit was better. |
