摘　　要：研究了不同龄期东亚飞蝗Locusta migratoria manilensis(Meyen)的耐饥饿能力和3龄后的东亚飞蝗在不同饥饿程度下的取食量和取食速度。结果表明,东亚飞蝗的耐饥饿能力基本随龄期的增加而增强,平均耐饥饿时间为46～116h;同一龄期的东亚飞蝗,饥饿12h后的取食量和取食速度均大于正常情况,饥饿24h后的取食量和取食速度与正常情况下差异不显著,饥饿36、48h后的取食量和取食速度均明显小于正常情况;饥饿程度越大,取食量就越小,取食速度越慢。Tolerance of starvation from the first instar to adult,and food intake and feeding rates at different times after starvation from the third instar to adult,of Locusta migratoria manilensis（Meyen）,was studied in a laboratory.The results indicate that starvation tolerance gradually increased with each instar with an average duration of resistance to starvation of 46-116 h.Within the same instar,food intake and feeding rate were higher than normal after 12 h of starvation,no different to normal after 24 h of starvation and obviously less than normal after 36 or 48 h of starvation.Appetite and feeding rate were inversely related to the degree of hunger.
