棉铃虫飞翔的能源物质及消耗

THE RELATIONSHIP BETWEEN UTILIZATION OF ENERGYSUBSTANCES AND SUSTAINED FLIGHT IN COTTONBOLLWORM, HELICOVERPA ARMIGERA

研究结果表明棉铃虫Ｈｅｌｉｃｏｖｅｒｐａａｒｍｉｇｅｒａ（Ｈüｂｎｅｒ）初羽化个体的能源储备主要为甘油酯，１日龄成虫甘油酯和糖原的含量分别为每头３．６３６５ｍｇ和０．３６５８ｍｇ，通过成虫期的取食，二者的含量分别于羽化后４ｄ和５ｄ达到高峰（６．５７０７ｍｇ和２．３５００ｍｇ）。对吊飞个体的测定表明甘油酯和糖原是棉铃虫飞翔的能源物质，蛋白质含量和飞行活动无明显的相关关系。４日龄成虫在飞行磨上吊飞６６ｈ，飞翔时间３７．９９４３ｈ，累积飞行２１６．８６５０ｋｍ。累积消耗能量２１８．７２Ｊ，其中甘油酯占８５．８７％，糖原占１４．１３％。

The relationship between utilization of triglyceride and glycogen and sustained flight in the moths of cotton bollworm, Helicoverpa armigera was investigated in the laboratory. It was found that the triglyceride was the main stored energy substance for flight, its content in a newly emerged individual was 36365 mg/moth, while the content of glycogen was 03658 mg/moth. With feeding sugar in adults, they increased to 65707 mg on the fourth day and 23500 mg on the fifth day, respectively. The content of protein in tethered flight moth changed negligibly, indicating irrelevant to flight activity, while there were negative correlations between the contents of triglyceride and glycogen and flight duration. The flight activities of the 4day old moths were detected for 66 h by flight mill, the moths flew 379943 h and covered a distance of 2168650 km with an energy consumption of 21872 J, in which the percentages of triglyceride and glycogen utilized were 8587% and 1413%,respectively.
