【摘要】 双斑长跗萤叶甲Monolepta hieroglyphica是玉米上的一种重要害虫。本试验在田间使用黄色粘虫板确定双斑长跗萤叶甲种群日活动规律，在室内观察成虫静息、移动、取食和交配行为的日节律。结果表明，双斑长跗萤叶甲成虫田间日活动高峰呈双峰型，14:00-16:00(28.00头/板)种群活动数量最高，10:00-12:00(23.33头/板)次之，夜间活动较少(5.33头/板)。室内行为日节律观察发现，该虫以静息行为占比最多(59.5%),其次是取食行为(21.6%)、移动行为(18.6%),交配行为最少(0.3%)。在黑夜静息行为显著高于白天，说明双斑长跗萤叶甲为昼行昆虫，雌性成虫和雄性成虫行为日节律在1 d内整体趋势相似，但活动高峰期的时间有差异。本研究明确了双斑长跗萤叶甲成虫行为日节律，以期为深入理解双斑长跗萤叶甲的活动周期，为室内种群建立和田间防控提供理论依据。更多还原

【Abstract】 Monolepta hieroglyphica is an important pest of corn. In this experiment, yellow sticky traps were used in the field to determine the diurnal activity rhythm of the M.hieroglyphica population, and the diurnal rhythms of adult resting, moving, feeding and mating behaviors were observed indoors. The results showed that the daily activity peak of adult M.hieroglyphica in the field presented a bimodal pattern, with the highest population activity at 14:00-16:00(28.00 individuals per trap), followed by 10:00-12:00(23.33 individuals per trap), and less activity at night(5.33 individuals per trap). Indoor observation of behavioral diurnal rhythm revealed that resting behavior accounted for the largest proportion(59.5%), followed by feeding(21.6%), moving(18.6%), and mating behavior was the least(0.3%). Resting behavior at night was significantly higher than that during the day, indicating that M.hieroglyphica is a diurnal insect. The overall diurnal behavioral rhythms of female and male adults were similar within one day, but the occurrence times of peak periods differed. This study aimed to clarify the diurnal behavioral rhythm of adult M.hieroglyphica, in order to further understand its activity cycle and provide a theoretical basis for indoor population establishment and field control.更多还原
