摘要
目的为了解莘县城区蟑螂的侵害现状,种群构成和季节消长规律,为制定合理的蟑螂防制政策提供科学依据。方法以粘捕法进行监测,对莘县城区内宾馆、餐饮店、超市、医院、农贸市场和居民小区6种生境进行蟑螂密度监测,根据监测结果,统计各种情况下的蟑螂侵害率和蟑螂密度。结果 2013~2017年,在莘县城区内的超市、医院、居民小区和餐饮店监测到了蟑螂,在农贸市场、和宾馆监测未从发现有蟑螂或蟑迹。4年共布放粘螂板3 600张,回收3 520张,捕获蟑螂447只,平均蟑螂密度0.13,平均蟑螂侵害率为5.57%;经监测2013年未监测到蟑螂,2014年后,陆续在超市、医院、餐饮店及居民小区内发现蟑螂或蟑螂,不同年份蟑螂侵害率呈逐年升高趋势(P<0.01);不同月份蟑螂密度及侵害率不同,7、9月份侵害率最高,达8.21%、8.84%,1、11月份侵害率较低,为3.41%、3.58%(P<0.01);有蟑螂侵害的几种生境,蟑螂侵害率差异无统计学意义(P>0.05);德国小蠊莘县的优势种属,占97.54%,其他种属蟑螂比例较小,占2.46%。结论莘县蟑螂侵入率逐年升高,德国小蠊为优势种属。
Objective To understand the current status of the infestations,the composition of populations and the seasonal fluctuations of the cockroaches in the urban area of Shen county,so as to provide scientific basis for the development of rational prevention policy. Methods The method of stickiness trapping was used to monitor the density of six habitats in hotels,catering stores,supermarkets,hospitals,farmers＇ markets,and residential communities in Shen county.According to the monitoring results,statistics were made on the rates of delirium and infestation under various conditions. Results During 2013-2017,cockroaches were detected in supermarkets,hospitals,residential communities,and catering outlets in the urban area of Shen county.There were no blemishes or traces found in the farmers＇ market and hotel monitoring.A total of 3 600 sticky sampan plates were placed,3 520 pieces were recovered,447 cockroaches were captured,the average density was 0.13,and the average infestation rate was 5.57%.After monitoring in 2013,no cockroach was monitored.After 2014,cockroaches were found in supermarkets,hospitals,restaurants,and residential communities.The rate of infestation was found to be increasing year by year（P〈0.01）.The densities and infestations were different in different months.The highest was in July and September,8.21% and 8.84%.The rate was low in January and November,3.41%and 3.58% respectively（P〈0.01）.There was no significant difference in the infestation rate in several habitats with infestation（P〉0.05）;The dominant species in Shen county was Blattella germanica,accounting for 97.54%,and the proportion of other species was relatively low,accounting for 2.46%. Conclusion The infestation rate of cockroaches in Shen county is increasing year by year,and Blattella germanicais the dominant species.
