研究了中华虎凤蝶引种至江西燕山地区后，1～5龄幼虫群体和个体的取食行为。实验结果显示，2～5龄幼虫在叶片向下的那一面取食，取食位置与叶片的正反面无关；2、3龄幼虫具有群体取食性，群体取食后集体休息，在取食间隔期基本无爬行活动，而人为分开的个体取食后在取食间隔期间爬行活动次数较多；不同龄期的取食效率随着龄期的增长而升高；同一龄期内幼虫一次取食时间呈规律性变化；4龄幼虫一次取食时间长短与其前后取食间隔总时间长短具极显著的相关性。综上所述，中华虎凤蝶幼虫的取食行为呈现出某种规律性，表明其取食行为不仅是受外在因素的影响，也受内部因子的调控。
Larval feeding behavior observation of introduced Luehdorfia chinensis Leech on the mountain yanshan
The feeding behavior of Luehdorfia chinensis Leech larvae was studied after they were introduced to the Mountain Yanshan of Jiangxi province.It was found that the 2~5 instars larvae preferred to be fed on the down side of the leaf blade,but neither depending on the positive side nor the negative side of leav-es.Individuals of the second and the third instar larvae tend to feed and rest in groups,they were rarely making crawling activities during feeding intervals,while the separated individuals crawl more frequently. The fourth and the fifth instar larvae crawl between the leaf blades alone,no feeding cluster phenomenon was observed.The feeding time of individuals in the same instar larvae was regularly changed.A significant correlationship was showed between the length of feeding time and the feeding interval time of the fourth instar larvae individuals.In summary,the feeding behavior of the L.chinensis larvae exhibited some regu-larity,which indicated that the feeding behavior of L.chinensis larvae was not only influenced by external factors,but also regulated by internal factors.
