蚊虫种群密度数量变动的监测和研究,是虫情预测预报,制定灭蚊防病对策和判断传病媒介的重要科学依据,是灭蚊达标的客观指标。兹将分别在全市连续调查近40年的结果,整理报告如下:材料与方法一、按五定法进行调查(定点、定人、定期、定时、定方法)。二、1952～1962年观察蚊虫的发生规律。三、1963～1973年研究种群密度数量、空间和时间变动因素的分析。
The monitoring and research on the change of population density of mosquitoes is an important scientific basis for insect forecasting, formulation of anti-mosquito disease prevention strategies and judgment of vectors, and is an objective indicator of achieving mosquito control. The results of the past 40 years will be continuously investigated in the whole city respectively. The report is organized as follows: Materials and Methods 1. Investigation according to the five methods (fixed point, fixed point, fixed time, fixed time and fixed method). Second, 1952 ~ 1962 observed the occurrence of mosquitoes. Third, from 1963 to 1973 study population density changes in quantity, space and time factors.
