于2011-2013年,采用网捕、扣捕和诱集等方法在北京地区通州马驹桥镇、大兴区亦庄镇、大兴区南海子公园、丰台区世博园、门头沟区王平镇、密云区古北口镇汤河村紫海香堤香草艺术庄园、西城区北京大学人民医院(老院)等地采集蝇类标本共计1328只.根据相关文献对所采集标本进行鉴定,整理.结果表明:共采集到北京地区丽蝇科(Calliphoridae)、麻蝇科(Sarcophagjdae)和蝇科(Muscidae)标本15亚科51属103种,其中,12种属北京地区首次记录.该结果对于澄清北京地区双翅目(Diptera)昆虫的物种多样性具有一定的研究意义. 相似文献

ObjectiveTo determine the incidence of anesthesia patient safety incidents at a university teaching hospital, develop interventions to address the most common incidents, and determine the effectiveness of these interventions.Study designPre-post intervention observational.AnimalsFour thousand, one hundred forty dogs and cats anesthetized by the anesthesia service.MethodsThe study was divided into two 11.5 month periods. During each period, incidents were logged (e.g. closed adjustable pressure limiting (APL) valve, esophageal intubation, and medication error). At the end of the first period, four countermeasures were incorporated into the service’s protocols: 1) prior to any drug injection, the individual would read out aloud the drug name, patient name, and route of administration; 2) use of a uniquely colored occlusive wrap over arterial catheters; 3) a check box on the anesthesia record labeled “Technician Confirmed Intubation”; 4) a check box on the anesthesia record labeled “Technician Checked OR (operating room)”. The number of patient safety incidents during period 1 and period 2 were compared using Fisher’s Exact Test.ResultsDuring Period 1, there were 74 incidents documented in 2028 patients (3.6%) including 25 medication errors, 20 closed APL valves, and 16 of esophageal intubation. During Period 2, there were 30 incidents documented in 2112 patients (1.4%) including 14 medication errors, 5 closed APL valves, and 4 of esophageal intubation. The proportion of events during Period 2 was significantly smaller than during Period 1 (p < 0.0001).Conclusions and Clinical relevanceImplementation of four simple interventions was associated with a significant decrease in the number of incidents. 相似文献

为了摸清我国已报道塔叶蝉的具体种类及分布情况,为后续中国塔叶蝉族昆虫系统分类研究奠定基础,通过查阅网络数据库及相关国内外文献资料,对该族叶蝉已知种类进行了初步整理。结果表明,截至目前,在我国已发现的塔叶蝉昆虫种类共计13属54种,占世界已知属的比例虽较高,但很多为单种属,还有很多未知种类等待我们去发现。 相似文献

A recent catalogue of the rich ant fauna of Morocco included 214 species, with later studies adding an additional 12 species. Following recent fieldwork in the north of Morocco, we report five new records for the country (Plagiolepis pygmaea Latreille, 1798, Ponera testacea Emery, 1895, Strumigenys tenuipilis Emery, 1915, Temnothorax pardoi Tinaut, 1987, and Tetramorium parvioculum Guillem & Bensusan, 2009) and we present new data on the distribution and natural history of six additional species. This work brings the total number of ants known from Morocco to 233, taking into account two species which were omitted in the list of Cagniant. 相似文献
