| 摘 要： | 研究亚油酸甲酯对朱砂叶螨的生物活性。采用玻片浸渍法和叶片残毒法测定生物活性。亚油酸甲酯具有较强的触杀、产卵抑制和驱避作用，浓度为5 mg/ml时，对朱砂叶螨的雌成螨和卵24h后的校正死亡率分别达到82.82%和78.54%，LC50分别为1.4434mg/ml和2.0283mg/ml；对雌成螨24h后的产卵抑制率和驱避率分别达到78.46%和95.61%。本试验为亚油酸甲酯作为杀螨活性物质的作用机理的探索提供了一定的理论基础。

| Abstract: | The methyl linoleate investigated for their biological activity againstTetranychus cinnabarinus . Slide, dip and Leaf,residue methods were used to measure biological activity. The results indicated that the bioactivity(touch kill, oviposit inhibition, repellency)of methyl linoleate was high , the adjusted mortalities of female mite and egg were 82.82% and 78.54%, Oviposit inhibit ion rate and repellency rate were 78.46% and 95.61%,respectively at the concentration of 5 mg/mL. LC50 is 1.4434 mg/mL and 2.0283... |
