摘要: 【目的】通过莲藕食根金花虫Donacia provostii Fairmaire成虫日活动行为节律的系统研究,以期为构建该虫的高效防控技术体系提供科学依据。【方法】采用室外单头隔离和雌雄配对饲养,将莲藕食根金花虫成虫的行为划分为离水静息、触水静息、取食、移动、交配和产卵6个类型,每30 min观察记录一次其活动行为,连续5 d,统计分析其活动行为的日节律。【结果】在时间上,莲藕食根金花虫成虫各行为在各时间点间和时间段间均存在极显著差异(P<0.001);在空间上,成虫各行为在不同位置发生的比例存在极显著差异(P<0.001)、且荇菜叶上和水面的各行为在不同时间点间存在极显著差异(P<0.001)。【结论】莲藕食根金花虫成虫活动行为存在时空上的差异,空间对其行为的影响较时间明显。

Abstract: 【Aim】In order to provide the important scientific basis for building effective prevention and control system of aquatic leaf beetle Donacia provostii Fairmaire, the diurnal rhythm of adult behaviors were studied. 【Methods】The adults were observed for 5 consecutive days and recorded in a 30 min interval by single rearing separately and rearing in pairs outside, and data was collected and analyzed. All behaviors were divided into six types: resting without contacting water (ROCW), resting with contacting water (RWCW), foraging (FG), moving (MG), mating (MT) and spawning (SG). 【Results】These results showed the adult behaviors of D. provostii were significantly different at various time points or in various time periods (P<0.001). The proportions of four behaviors were significantly different in different spatial positions (P<0.001), and the behaviors on leaf of Nymphoides peltatum (Gmel.) Kuntze or water surface were also significantly different at different time points (P<0.001). 【Conclusion】Both temporal and spatial variation could significantly influence the behaviors of the waterleaf beetle, and the effect of spatial variation is more significant than that of the temporal variation.
