New species of Notophthiracarus (Acari: Oribatida: Phthiracaroidea) from Tanzania

Three new species of the genus Notophthiracarus are described, identified and figured from Uluguru Mountains of Tanzania: Notophthiracarus quasiuluguruensis sp. nov, Notophthiracarus tuberculus sp. nov, and Notophthiracarus uluguruensis sp. nov. A comparison with the most closely related species of the genus Notophthiracarus is also presented.

Thermoperiodically induced diapause in a mite in constant darkness is vitamin A dependent

Summary By rearing the predacious miteAmblyseius potentillae in a daily temperature cycle in constant darkness it could be shown that diapause may be thermoperiodically induced. When the same experiments were performed using diets without vitamin A it appeared that vitamin A is necessary to achieve a state of reproductive diapause in this mite.2 February 1987     

Does the moon influence the predatory activity of mites?

Periodicity in predatory activity was observed in overwintered females ofTyphlodromus pyri Scheuten (Acari: Phytoseiidae). Chronobiometrical analysis revealed that an approximately circabiseptan (about-14-day) rhythm is statistically significant, with a striking depression around the full moon.     

诺木洪白枸杞瘤瘿螨的空间分布型及抽样技术

本文对诺木洪白枸杞瘤瘿螨虫瘿在不同时间东、南、西、北4个方位和上、中、下3层的空间分布做了调查,采用7种聚集度指标和6种回归模型检验确定白枸杞瘤瘿螨虫瘿的空间分布型,确定田间理论抽样数。结果表明:白枸杞瘤瘿螨虫瘿的空间分布型为聚集分布,并且虫瘿内瘿螨个体间相互排斥;白枸杞瘤瘿螨虫瘿在田间的最适理论抽样模型为:n=t2/D2(-6.43m+0.359)。     

储藏中药材孳生粉螨的研究

采用了清水漂浮法和塔氏电热集螨器分离法，共分离中药材样品146种，1460份，从中分离出粉螨48种，隶属7科25属。得出结论：中药材粉螨的污染严重，应加强对中药材螨类的防治，以保护中药材及预防人体螨病。

云南文山州西华公园甲螨资源调查研究

为了解云南文山州甲螨种群的分布,以合理应用该地区的甲螨生物资源。采用野外选点现场取土样,应用Tullgren装置分离甲螨,并将所获甲螨分科列出名录。发现获取的甲螨种类相当复杂,现已鉴定的甲螨33种,隶属21科。因此,文山州土壤甲螨种类繁多,具有进一步研究、开发和应用价值。     

粉尘螨过敏原脂肪酶的表达、纯化及生物信息学分析

为克隆原核表达并纯化出粉尘螨过敏原脂肪酶蛋白,鉴定其免疫学活性,并分析其分子特征.通过重组合成粉尘螨新过敏原脂肪酶基因,与p ET-28a载体连接后转化大肠埃希菌E.coli Top10,用异丙基-β-D-硫代半乳糖苷(IPTG)诱导表达重组新过敏原脂肪酶蛋白;经镍柱亲和层析纯化出粉尘螨重组脂肪酶蛋白,用Western Blot、ELISA方法检测其免疫原性.用生物信息学软件预测其理化性质、二级结构,并构建分子进化树.成功表达纯化出高纯度的粉尘螨重组脂肪酶蛋白,十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)结果显示表达重组产物分子质量约为40 k Da,与理论值一致,纯化后的表达产物经Western blot印迹检测有明显条带显示.信息学分析显示蛋白二级结构由α螺旋(16.38%)、延伸主链(18.93%)、无规则卷曲(64.69%)组成.成功原核表达出粉尘螨过敏原脂肪酶蛋白,并纯化获得较高纯度及较强免疫学活性的重组脂肪酶蛋白,为尘螨过敏性疾病的特异性诊断和免疫治疗奠定理论基础.

Species associations of oribatid mites in lichens on the island of Ailsa Craig,Firth of Clyde (Acarei: Cryptostigmata)

Species associations of oribatid mites in maritime lichens on the island of Ailsa Craig, Firth of Clyde, were investigated. The thirteen lichen species examined yielded a total of seventeen oribatid species assignable to two discrete associations. One was characteristic of foliose lichens on exposed rocks and the other was found in terricolous fruticose lichen on acid healthland. Morphology of the lichen thallus and altitude of the collection site were found to influence the abundance, occurrence and species diversity of the mites.
