蚊子是吸血昆虫,它通过叮咬,传播乙型脑炎、丝虫病、疟疾等传染病,危害性极大,严重影响人民健康和抓革命、促生产。蚊子的生长繁殖过程,是卵→孑孓→蛹→蚊。孳生的条件是气温、血食、水。其中水为重要因素,因为蚊子的印、孑孓、蛹必须在水中生长。所以各种积水的地方,如沟、浜、缸、甏(bèng)、竹节、树洞、石穴等都是蚊子的孳生地。根据蚊子活动的规律,一年中有五个消灭蚊子的重要时期:第一是消灭早春第一代蚊子及幼虫:第二是在梅雨季节前后,全力控制蚊子孳生地(排除积水);第三是夏秋两季全力控制孳生地
Mosquitoes are blood-sucking insects, which transmit infectious diseases such as Japanese encephalitis, filariasis and malaria through bites. They are extremely harmful and seriously affect people’s health and revolution and promote production. Mosquito growth and reproduction process, eggs → larvae → pupa → mosquito. Breeding conditions are temperature, blood, water. Water is an important factor, because the mosquito’s seal, larvae, pupa must grow in water. Therefore, a variety of stagnant water, such as ditch, hamam, cylinder, 甏 (bèng), bamboo, tree holes, rock caves and so are the breeding grounds of mosquitoes. According to the law of mosquito activity, there are five important periods to eradicate mosquitoes in a year: the first is to eliminate the first generation of mosquitoes and larvae in the early spring; the second is to control mosquito breeding places before and after the rainy season (excluding stagnant water); Third, full control of summer and autumn breeding ground
