Evaluation and analysis of vector control in Langfang City in 2023
Objective To investigate the effect of vector control in Langfang City,so as to provide scientific basis for the establishment of national health city.Methods The density of rodents,mosquitoes,flies and cockroaches in Anci District,Guangyang District and Kaifa District of Langfang City was investigated in 2023.Rodents were monitored by tracing method,mosquitoes by path method,spoon method and human attraction and landing method,flies and cockroaches by visual observation method.Excel 2010 software was used to calculate and analyze the data.And the effect of vector control was evaluated.Results Rodents:The rodent traces indoor,the pass rate of rodent prevention facilities in key industries and the path index of the external environment were 0.54％,97.34％and 3.04 places per km,respectively.Mosquitoes:The path index of small waters,the average sampling spoon index of large and medium-sized waters and the landing index of external environment were 0.61 places per km,0 and 0.53 mosquitoes per person,respectively.Flies:The density of adult flies in indoor environment was 3.20％,the density of flies in positive room was 2.50 flies per room,the pass rate of fly prevention facilities was 97.10％,and the positive rate of fly breeding density control level in external environment was 4.86％.Cockroaches:The positive rate of cockroach trace and the infestation rate of cockroach nymphs were 3.20％and 0.24％,respectively.All the cockroaches were Blattella germanica,and no Periplaneta and ootheca were found.Conclusion Through the vector control activities were carried out in an all-round way,so that the comprehensive evaluation of rodents,mosquitoes and flies control level in the built up area of Langfang City was level C,and the comprehensive evaluation of cockroaches control level was level B.Some key sites and units still have inadequate vector control,need to further improve the vector density control and the construction of fly and rodent control facilities in key places,carry out regular the investigation and evaluation of the effect of vector control,and understand the status of reaching the target through the evaluation.
