Pages: 1413-1417
Year: Issue:  12
Journal: Acta Entomologica Sinica

Keyword:  腐食酪螨 报警信息素 行为反应 橙花醇甲酸酯 Z-柠檬醛 E-柠檬醛;
Abstract: 【目的】确定腐食酪螨Tyrophagus putrescentiae报警信息素的存在及其成分。【方法】采取正己烷溶剂浸提法提取获得腐食酪螨螨体提取物,通过观察腐食酪螨对提取物的行为反应确定其生物活性,最后用气相色谱-质谱联用仪(gas chromatograph-mass spectrum,GC-MS)对提取物的成分进行分析。【结果】腐食酪螨正己烷提取物对该螨有明显的报警作用。GC-MS分析显示,提取物中含有橙花醇甲酸酯、Z-柠檬醛、E-柠檬醛等成分。【结论】该实验证明了腐食酪螨报警信息素的存在,为进一步明确各成分及其作用奠定了基础。
