【摘要】：目的了解天津地区医院病媒生物监测点德国小蠊侵害和种群密度及季节消长,为医院的德国小蠊防治提供依据。方法 2006-2014年在天津地区医院病媒生物监测点用粘捕法对病房的德国小蠊进行监测,并对监测结果进行统计分析。结果 2006-2014年天津地区医院病媒生物监测点德国小蠊总体平均侵害率5.18%,平均密度0.25只/张。在16个监测区县中,经济欠发达的郊县地区(老五县)和新兴工业区(环城四区)的医院德国小蠊侵害率和密度相对较高,市内六区和滨海新区较低。德国小蠊侵害率及密度的季节消长呈单峰型,高峰为5-8月的夏季。德国小蠊侵害率和密度有年度波动现象,侵害率2007年最高,2013年最低;密度2008年最高,2013年最低。结论初步掌握了天津地区医院德国小蠊的侵害特征、种群密度、区域差异、季节消长和年度变化规律,为医院德国小蠊监测、风险评估、预测预警及控制提供基础数据。
[Abstract]:Objective to investigate the invasion, population density and seasonal change of Blattella germanica in hospital vector biological surveillance sites in Tianjin area, and to provide evidence for the prevention and control of cockroach germanica in hospitals. Methods from 2006 to 2014, the germanic cockroach in the wards was monitored by viscous capture method at the vector biological monitoring sites in hospitals in Tianjin, and the monitoring results were statistically analyzed. Results from 2006 to 2014, the average invasion rate of Blattella germanica was 5.18, with an average density of 0.25 / tensor. The infection rate and density of Blattella germanica were relatively high in the underdeveloped suburbs (Laowu County) and Xinxing Industrial Zone (four districts around the city), but lower in the six districts of the city and the Binhai New area. The seasonal variation of the invasion rate and density of Blattella germanica showed a single peak, the peak was in the summer of May to August. The infective rate and density of Blattella germanica fluctuated annually, the infective rate was the highest in 2007 and the lowest in 2013, and the highest in 2008 and the lowest in 2013. Conclusion the infective characteristics, population density, regional difference, seasonal fluctuation and annual variation of Blattella germanica in hospitals in Tianjin were preliminarily grasped, which provided basic data for monitoring, risk assessment, prediction and early warning and control of Blattella germanica in hospitals.
