The exact of petroleum ether was the acaricidal active site of Eungenia caryophyllata. 3.Isolation, purification and identification of compounds with acaricidal activity in Eugenia Caryphyllata: The exact of petroleum ether was separated into 6 parts by silica gel column chromatography with gradually increasing polarity of petroleum ether: ethyl acetate. The part C was demonstrated to be the most effective part by acaricidal activity test in vitro,and the time for it to kill all experimental mites was about 20 min.

丁香杀螨活性成分的追踪分离、纯化与结构鉴定：采用硅胶柱层析法，以石油醚：乙酸乙酯溶剂系统梯度洗脱，对丁香石油醚提取物进行分离，得到A~F 等6 段混合物，离体杀螨试验发现，C 段混合物具有突出的杀螨活性，50%浓度平均15min可杀死全部供试螨虫。

The stages from larva to the protonymph, or from protonymph to the deutonymph, were more sensitive to photoperiod than other stages, however, among these a single developmental stage could not induce diapause.

结果表明21℃下，临界光周期为12 h 32 min，光敏感螨态为幼螨至第二若螨之间的连续两个螨态，单独一个发育阶段对短光照不敏感或仅有微弱的感应。

The leaves were transported to the laboratory where densities of Phytoseiidae and of the most common mite families (e.g., Tetranychidae, Tenuipalpidae, Eriophyidae, Tydeidae, Winterschmidtiidae) were evaluated under a binocular microscope.

每次取样，每两个相同的样品需要收集10片叶子，采样得到的叶子将被送往实验室，在双筒显微镜下，可以对植缨螨科，以及最常见的螨科（如叶螨科，细须螨科，瘿螨科）的密度进行评估。
