Scope

Scope: This document stipulates the principles, general methods, prevention procedures, and information management for the prevention and control of vector-borne organisms in Shenzhen's municipal drainage network, and provides relevant information. This document applies to the prevention and control of vector-borne organisms (mosquitoes, cockroaches, and rats) in Shenzhen's municipal drainage network. Main technical content: 4. Prevention principles 4.1 Adhere to the principles of prevention-oriented, environmental safety, economic feasibility, and social acceptability. 4.2 Take environmental prevention as the core, combine physical and chemical prevention measures, and adopt a multi-pronged approach to effectively control the hazards of vector-borne organisms in the municipal drainage network. 5. Monitoring methods 5.1 Density monitoring of cockroaches a) Operating steps: Walk along the distribution of manholes in the operation area to check the occurrence of cockroaches in no less than 20 sewage wells and rainwater wells along the line, and record the number of monitoring points and the number of monitoring points where adult or larval cockroaches are found, expressing the cockroach density as a positive rate. b) Calculation method: See Equation (1) for the calculation of cockroach density (for the specific formula, please refer to the standard text) — Positive rate, unit: percentage (%) — Number of positive wells, unit: wells — Number of monitoring points, unit: points. Mosquitoes a) Operating steps: Walk along the distribution of manholes in the operation area to check the occurrence of mosquitoes in no less than 20 sewage wells and rainwater wells along the line, and record the number of monitoring points and the number of monitoring points where mosquitoes are found, expressing the mosquito density as a positive rate. b) Calculation method: See Equation (2) for the calculation of mosquito density (for the specific formula, please re
