To explore the extraction methods of genomic DNA of parasitic mites Demodex folliculorum D.

探索人体毛囊蠕形螨和皮脂蠕形螨DNA的提取方法。

The body of demodex folliculorum is slim and is in a worm shape, it has just several uncompletely revolutioned legs.

毛囊蠕形螨的螨体细长呈蠕虫状，仅仅有一些没有完全退化的腿。

A number of the imagines,nymphs and eggs of human Demodex are found in the enlarged hair follicle injured skin of the patient's feature and the hyper plasic sebaceous glands and there are some infections of different degree around...

结果表明，蠕形螨寄生与皮肤组织病理改变有密切关系，是酒渣鼻病的重要致病因素之一。提示，治疗酒渣鼻病应采取杀灭螨虫和抑制炎症反应等综合治疗措施疗效较好。

Results The dermatophagoides farinae and pteronyssinus (62/118) were the most common allergen in inhalation group in 118 patients with allergic disease. Dogly or feline scurf was the next (35/118), then were ambrosia artemisiiofolia and muguort (14/118), cockroach(12/118), cypress, elm, Surname. Cottenuood (8/118), humulus scandens (7/118), polyvalent fungus(6/118). In food group the most common allergen was mutton or beef (13/118), then was cashew, peanut, soybean (11/118), wheat (10/118),milk (9/118), fish, shrimp, crab(5/118), mango(4/118),egg, chicken., yolk(1/118).The positive rates of total IgE level was 35.59%.

结果 118例变应性鼻炎患者中吸入组过敏原以以屋尘螨粉、尘螨(62/118)为最高，其后依次为猫毛皮屑、狗毛皮屑(35/118)、矮豚草、蒿(14/118)、蟑螂(12/118)、柏榆、梧桐、柳三角叶杨(8/118)、律草(7/118)、点青霉、分枝孢霉、烟曲霉、交链孢霉(6/118)；食入组过敏原以牛肉、羊肉(13/118)为最高，其后依次为腰果、花生、黄豆(11/118)、小麦(10/118)、牛奶(9/118)、鱼虾蟹(5/118)、芒果(4/118)、鸡蛋白、鸡蛋黄(1/118)；总IgE阳性率为35.59%。

Indoor rearing and field systematic observations were carried out to explore the life history and behavior of Allothrombium ovatum Zhang et Xin,an ectoparasitic/ predatory mite on aphids in northern China.

卵形异绒螨Allothrombium ovatum是我国北方地区蚜虫的一种外寄生性天敌，室内饲养和田间系统观察结果表明：该螨1年发生1代，以卵在土壤内越冬。

The niche breadth could be used as an index for evaluating the host specificity of gamasid mites, whose similarity in population distribution was largely related to that of their hosts, as well as their taxonomic distance.

生态位宽度可以作为评价革螨宿主特异性的定量指标，革螨种群分布的相似性与其宿主的相似性程度有着很大的关系，并受其动物分类学远近的影响。

Non-parametric Mann-Whitney U -test showed that there was no significant difference between male and female hosts on the species richness and abundance of total ectoparasites, chigger mites, sucking lice, fleas or gamasid mites.

U 检验表明，体表寄生虫、恙螨、吸虱、蚤类和革螨的数量和物种数在雌雄宿主体表间的差异无统计学意义。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
