摘要
东亚飞蝗的发生面积、发生程度主要受残蝗面积、密度和降水条件的影响;库、湖蝗区的宜蝗面积主要受库、湖水位的影响。同时,东亚飞蝗的发生期主要受蝗卵发育期温度条件的影响。利用上述因子分别对东亚飞蝗的发生面积、发生程度及密度、3龄盛期进行预报,简便易行,准确可靠,时效性强,对指导防治工作十分有益。
The occurrence area and degree of Locusta migratoria rnanilensis were mainly affected by the occurrence area and density of surviving individuals and rainfall, while the area suitable for the locust was mainly influenced by water level in reservoir and lake region. And occurring period of the locust was affected by the temperature of the developmental stage of locust eggs. The forecast of the locust, including the occurring areas, occurring degree, occurring density and fastigium stage of the 3rd instar locust, can be convenient, exact, timely and beneficial to the control work by using the above results.
