温度及气调对薰衣草油防治腐食酪螨效果的影响

应用四元二次正交旋转组合设计,研究了温度(X_1)和CO_2,(X_2)、O_2、(X_3)薰衣草油Lavandula angustifolta Mill(X_4)浓度对腐食酪螨Tyrophagus putrescenrice 雌成螨死亡率(Y)的影响.结果表明:(?)=55.833+1.823X_1+10.781X_2-10.052X_3+13.281X_4-1.172X_1X_2+6.328X_1X_3-1.328X_1X_4+5.234X_2X_3+4.14X_2X_4+2.578X_3X_4+6.289X_1~2+3.945X_2~2-1.055X_3~2-3.086X_4~2主效因子分析得出,影响该螨死亡率的因素依次为:药剂浓度,CO_2浓度和温度。温度和O_2浓度间的交互作用最为明显。

THE INFLUENCE OF TEMPERATURE AND MODIFIED ATMOSPHERE ON EFFECTIVENESS OF CONTROL OF Tyrophagus putrescentiaes WITH THE OIL Lavandula anguslifoliu Mill

A design of orthogonal conic substitution of 4 factors and 5 levels was adopted tostudy the influences of temperature(X_1),CO_2 concentration(X_2),O_2 concentration(X_3)and the concentration of oil plant of Lavandula angustifolia Mill(X_4) on the mortality offemale adults of Tyrophagus putrescentiae(Schrank)(Y).A regression was established as(?)=55.833+1.823X_1+10.781X_2-10.052X_3+13.281X_4-1.172X_1X_2+6.328X_1X_3-1.328X_1X_4+5.234X_2X_3+4.14X_2X_4+2.578X_3X_4+6.289X_1~2+3.945X_2~2-1.055X_3~2-3.086X_4~2According to the coefficient of each item in the model,the major factors affecting mitemortality were arranged in the sequence of plant oil concentration>CO_2concentration>O_2 concentration,The interaction between temperature and O_2concentra-tion appeared to be the highest in the study,though it was not significant statistically.
