铁路旅客列车德国小蠊密度监测方法的调查研究

目的 比较铁路旅客列车蟑螂各种监测方法之间的实效性,为蟑螂密度调查提供科学依据.方法 采用目前常用的蟑螂密度监测方法目测法、粘捕法、药激法在同一现场进行对比试验.结果 目测法、药激法、粘捕法测定蟑螂密度,阳性率分别为4.43％、1.44％、13.69％.密度指数分别为2.94只/车厢、3.98只/车厢、5.94只/车厢,对3种方法阳性率进行统计学检验,x2=398.77,P＜0.05,差异有显著性意义,其中粘捕法检出效果最高.结论 3种方法有各自特点,应当结合监测时间、监测目的,选取合适的方法进行铁路站车蟑螂的监测.

The Investigation of the Density-monitoring Methods for Blattella Germanica in Passenger Train

Objective To verify the practicality and comparability of the methods for monitoring the density of Blattella germanica in Passenger train, and to provide the scientific basis for the investigation of cockroaches density. Methods According to the methods for monitoring the density of cockroaches which were used often at present, and carrying out the contrast experiment at the same place. Results The examined rates of rang estimating, drug arousing and gluing to catch were 4.43% , 1.44% and 13.69% respectively. The density index were 2.94,3.98 and 5.94, Comparing the results of three methods, X2 = 398.77 , P 〈 0. 05. The differences had remarkable significances and the examined rate of gluing to catch was the highest of the three methods. Conclusion It was necessary to take scientific monitor methods for controlling cockroaches.
