To comprehensively understand the composition, density, distribution, seasonal fluctuations, and control strategies of mosquito species, and to provide a scientific basis for risk assessment, forecasting, early warning, and control planning for mosquito-borne infectious diseases such as dengue fever and Zika virus disease, the National Health Commission and the Chinese Center for Disease Control and Prevention require disease control departments at all levels nationwide to conduct mosquito density monitoring and collect mosquito specimens for morphological identification, drug resistance testing, and pathogen detection. Therefore, certain requirements are set for mosquito specimen collection: high mosquito attraction efficiency, low proportion of other insects, intact morphology, and good activity levels, to facilitate subsequent morphological observation, pathogen isolation, and nucleic acid extraction. Thus, professionals typically collect mosquitoes through trapping to achieve these objectives.
