目的开展某船运基地蟑螂危害状况调查,评价基地食堂和舰艇的蟑螂防治效果。方法蟑螂密度调查和效果评价采用药激法,蟑螂防治通过卫生整治和综合化学药物灭蟑相结合。结果食堂和舰艇的平均蟑螂侵害率为65.96%,平均蟑螂密度为5.59只/间。分类鉴定蟑螂3种,德国小蠊(90.25%)为食堂和所有舰艇的优势种。食堂蟑螂密度为7.3只/间,以熟食间(26.0只/间)和副食库(22.0只/间)相对较高;舰艇平均蟑螂侵害率为61.82%,平均蟑螂密度为5.21只/间,舰艇后厨均有蟑螂,且蟑螂密度(18.79只/间)最高。灭蟑处理后1周,食堂和5艘舰艇的灭蟑率在95%以上;首次灭蟑1个月后巩固灭蟑并监测蟑螂密度,食堂和4艘舰艇未发现蟑螂;3个月后监测蟑螂密度,食堂和6艘舰艇未发现蟑螂。结论分析某陆军船运基地蟑螂危害原因,蟑螂主要是随食品和货物侵入食堂和舰艇,且危害较重,分布范围较广,通过综合灭蟑措施,蟑螂危害得到有效控制。
Objective To investigate the status of cockroach hazards in a shipping base and evaluate the control effect of cockroaches in canteens and naval bases. Methods Cockroach density survey and evaluation of effects using the method of stimulus, cockroach prevention and treatment through the combination of sanitation and integrated chemical drugs cockroaches. Results The average cockroach attack rate in canteens and warships was 65.96%, and the average cockroach density was 5.59 / room. Three species of cockroaches were identified by classification, and Blattella germanica (90.25%) were the dominant species in the canteen and all warships. The density of cockroach in canteen was 7.3 / room, with cooked food room (26.0 / room) and non-staple food restaurant (22.0 / room) relatively high. Average cockroach attack rate was 61.82% and average cockroach density was 5.21 / After the cockroaches have cockroaches, and cockroaches density (18.79 / room) the highest. One week after the cockroach treatment, the cockroach killing rate of the canteen and the five warships was over 95%. After the first cockroach killing one month, the cockroaches were consolidated and the cockroach density was monitored. Cockroaches were not found in the canteen and the four warships after 3 months Cockroach density, canteens and cockroaches found in six ships. Conclusion The cause of the cockroach in a shipping base in the army is analyzed. The cockroaches mainly invade the canteen and the warship with the food and the goods, and are more harmful and widely distributed. The cockroach hazards are effectively controlled through the integrated cockroach measures.
