为了解天敌昆虫伞裙追寄蝇(Exorista civilis Rondani.)的飞行规律,本文采用吊飞试验及相关生理生化方法,研究了不同日龄伞裙追寄蝇体内甘油酯、糖原的积累状况及5日龄不同飞行时间其体内能源物质的变化情况。结果表明:5日龄雌蝇体内糖原、甘油酯含量均到达高峰,分别为114.3517和0.7537mmol·L~(-1);雄蝇则在7日龄糖原、甘油酯含量达到最高,分别为111.6680和0.7214mmol·L~(-1)。5日龄伞裙追寄蝇飞行60min后体内糖原含量显著下降;在飞行120min后甘油酯含量下降明显。飞行60min后体内糖原含量显著下降,说明伞裙追寄蝇体内糖原含量能维持60min的飞行,120~240min后糖原含量达到最低,此时甘油酯含量也有明显降低的趋势,说明120min后糖原迅速耗尽,此后飞行所需的能量由甘油酯提供。
In order to understand the flight rule of the natural enemy insect Exorista civilis Rondani, this paper studied the accumulation status of glycerides and glycogen in different day-old umbrella skirts by using the hang-off test and the related physiological and biochemical methods, 5-day-old at different times of its energy substances in the body changes. The results showed that the contents of glycogen and glycerol reached the peak at 5 days of female flies, which were 114.3517 and 0.7537 mmol·L -1, respectively. The male flies reached their maximum on the 7th day with glycogen and glycerol 111.6680 and 0.7214mmol·L -1. The content of glycogen in the 5-day-old umbrella skirt was significantly reduced after 60min flight and the content of glycerol decreased significantly after 120min flight. After 60min flight, the content of glycogen in body decreased significantly, indicating that glycogen content in umbrella skirt could be maintained for 60min flight. After 120 ~ 240min, the content of glycogen reached the lowest. At this time, the content of glyceride also decreased significantly, indicating that after 120min The glycogen is rapidly depleted and the energy required for flying thereafter is provided by the glycerides.
