中文摘要：
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46~116 h；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24 h后的取食量和取食速度与正常情况下差异不显著，饥饿36、48 h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。
英文摘要： 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.
