Abstract

OBJECTIVE

To investigate the distribution and density of mosquito populations and the resistance of to insecticides in Jiangsu Province in 2018 and 2019.

METHODS

During the period from June to October in 2018 and 2019, six counties (districts, cities) were sampled in southern, northern and central Jiangsu Province as surveillance sites. The density of mosquitoes was measured overnight using the light trapping technique. In addition, mosquitoes were collected from Hai'an of Nantong City and Yandu District of Yancheng City, central Jiangsu Province, and the sensitivity of female first filial generations to dichlorodiphenyltrichloroethane (DDT), malation, proposur, beta cypermethrin and deltamethrin was tested using the standard WHO insecticide susceptibility test assay.

RESULTS

A total of 104 423 mosquitoes were captured in six surveillance sites of Jiangsu Province in 2018 and 2019, and (49.11%), (28.38%), and (21.04%) were predominant species. The density of mosquitoes started to increase since early June, peaked in July and tended to be low in late October. mosquitoes captured from Hai'an was susceptible to malation, while those from Yandu District were moderately resistant to malation. mosquitoes from both Yandu and Hai'an were moderately resistant to proposur, and were resistant to DDT, beta cypermethrin and deltamethrin.

CONCLUSIONS

, and are predominant species in Jiangsu Province. is resistant to DT, beta cypermethrin and deltamethrin in central Jiangsu Province.

摘要

目的

调查2018年和2019年江苏省蚊虫种群分布、密度及对杀虫剂的抗性。

方法

2018年和2019年6至10月，在江苏省南部、北部和中部抽取6个县（区、市）作为监测点。采用灯诱法通宵测定蚊虫密度。此外，从江苏省中部南通市海安市和盐城市盐都区采集蚊虫，采用世界卫生组织标准杀虫剂敏感性试验方法检测雌蚊第一代对滴滴涕、马拉硫磷、残杀威、高效氯氰菊酯和溴氰菊酯的敏感性。

结果

2018年和2019年江苏省6个监测点共捕获蚊虫104423只，其中淡色库蚊（49.11%）、致倦库蚊（28.38%）和三带喙库蚊（21.04%）为优势蚊种。蚊虫密度自6月初开始上升，7月达到高峰，10月底趋于下降。海安市捕获的淡色库蚊对马拉硫磷敏感，而盐都区捕获的淡色库蚊对马拉硫磷呈中度抗性。盐都区和海安市捕获的致倦库蚊对残杀威均呈中度抗性，对滴滴涕、高效氯氰菊酯和溴氰菊酯均有抗性。
