亚洲飞蝗调查预报方法研究与探讨

Methods of survey and prediction of Asian migratory locust(Locusta migratoria migratoria L.)

亚洲飞蝗是重要的农业害虫。根据亚洲飞蝗的发生规律、分布及为害特点,明确了种群发生程度及分级指标,确定了在常发区定点调查以"春季卵存活情况调查、蝗蝻和成虫调查、边境蝗情调查和残蝗普查"为重点的调查内容,在偶发区采取普查方法,在此基础上提出了发生期、发生面积、发生程度的预测方法,为亚洲飞蝗监测和防控提供了科学依据。

Asian migratory locust （Locusta migratoria migratoria L.） was crucial pest in agriculture. According to its occurrence characteristics, distribution and population dynamics in China, occurrence degree and damage index of the locust were studied. Key investigation items, including survivals of eggs overwintered in spring, number of larval and adult of locust, statues of locust population in border area and remnants of locust in autumn were monitored in public area. And based on field investigation, the forecasting method for prediction on occurrence period, infestation area and damage index were proposed, which offer scientific support for locust monitoring.
