长足大竹象成虫取食行为

Feeding Behavior of Cyrtotrachelus buqueti

  • 摘要: 探索长足大竹象(Cyrtotrachelus buqueti)成虫取食行为。本文通过室内饲养观察和野外观察的方法,记录完整的取食过程,比较长足大竹象在不同寄主上取食行为的差异。结果表明:长足大竹象一次完整的取食包括搜寻、试探、进食和清洁4个阶段,雌雄都有多次取食行为。室内试验证明,长足大竹象进食和清洁时间明显长于搜寻和试探时间,雄虫搜寻、试探时间长于雌虫,而雌虫进食、清洁时间长于雄虫。长足大竹象在不同寄主植物上的取食时间存在差异,长足大竹象嗜食慈竹,对四季竹、麻竹、小琴丝竹竹笋少有取食,慈竹上笋选择次数、取食次数、取食孔数和取食面积显著多于其他3种竹笋,搜寻时间低于其余3种竹笋,而取食和清洁时间长于其余3种竹笋。林间长足大竹象的取食行为与室内观察结果基本一致。研究结果有助于了解长足大竹象取食行为,也对研究该虫的行为控制技术提供了依据。

     

    Abstract: This study aimed to explore buqueti(Cyrtotrachelus buquet) adult feeding preferences.The whole feeding process of C.buqueti was recorded and compared in feeding behavior on different hosts,by the combination of laboratory rearing with field observation.The result showed that a complete feeding of C.buqueti involved four phases:searching,probing,eating and cleaning.There were multiple feeding behavior for both female and male adults.Laboratory observation showed that the time of eating and cleaning was significantly longer than that of searching and probing,the males spent more time on searching and probing than the females,but the females' eating and cleaning time was longer than the males.The feeding time of C.buqueti in different hosts was different.C.buqueti adults most liked eating bamboo shoots of Sinocalamus afris,hardly ate Arundo donax,and the other three bamboo shoots.On S.afris,their choice times,feeding times,feeding holes and feeding area were significantly more than on the other three kinds of bamboo shoots,and their searching time was less,their feeding and cleaning time was longer than on the other three bamboo shoots.The feeding behavior of C.buqueti observed in the field was basically consistent with the results observed in the laboratory.The results could help us understand the feeding behavior of C.buqueti adults,and further provide scientific basis for the research of behavior control technology of this insect.
