Abstract:

　【Abstract】　Objective　To understand the ecological situation of cockroaches indoor in Lanzhou city, and to provide reference for its control. Methods　Sticky paper method was used in this study. Results　Blattella germanica was the dominant species. The seasonal fluctuation of cockroach density had high positive correlation with average temperature of the same period. The infestation rate was 22.87%. The infestation of cockroach in hotel was the most serious, and the infestation rate was 48.93%. Compared to 2005, the infestation of cockroach in hospital and residential areas changed largely in 2007. The cockroach density and its infestation in hospital increased 100 times and 12.76 times, respectively. In residential areas, it was 1.48 times and 0.82 times, respectively. That in new urban areas increased 2.60 times and 0.72 times, which were 1.90 times and 1.57 times of that in old uyban areas respectively. Conclusion　The integrated control measure should be taken according to the seasonal fluctuation of cockroach density in Lanzhou. It should put the emphasis on the environment management, plus physical control, chemical control and biological control. It should strengthen the control of cockroach in hotel, residential areas and restaurant, especially the control of Blattella germanica. It should carry out the public education and increase public awareness of disease prevention. At the same time, strengthen the surveillance of density, population dynamics and resistance, and work out timely the control measure according to monitoring data.
