蝗虫主要的发生地区大部是在低洼地带、沿湖海滨的大面积的荒草芦苇地,因此每年蝗虫的盛衰受水涝干旱的影响很大,几年来我们在治蝗工作中深切的体会到沿湖及沿河泛区的水位与蝗虫发生的关系上是十分密切的,因此根据水位变化来侦查蝗情是掌握蝗情的主要方法之一。由于水位涨落而引起环境上的改变,如干旱年份,大批荒草芦苇地积水下退,荒地面 Most locusts are mostly in low-lying areas along the lake coast of a large area of ​​reeds, so the annual rise and fall of the great impact of floods and droughts, over the past few years we deeply understand the work of locust control along the The relationship between the water level of the lake and the river flooding area and locust occurrence is very close. Therefore, locating the locust situation according to the water level change is one of the main methods for locust locust control. As the water level fluctuations caused by the environmental changes, such as drought years, a large number of weeds reed groundwater to retreat, wasteland
