适用于蚜虫等微小昆虫的飞行磨系统

介绍了一套采用计算机进行控制和数据采集的适用于蚜虫等微小昆虫的飞行磨系统。该系统能同时对32头昆虫进行飞行测试，并对测试数据进行自动分析处理。利用该飞行磨系统对不同日龄禾缢管蚜的飞行能力进行了初步测试。结果表明，禾缢管蚜在第1至第5日龄的飞行能力最强，明显高于第7和第9日龄。平均飞行时间在各日龄之间差异不显著，但平均飞行速度随日龄的增加而逐渐降低。本文对飞行磨结构、数据采集接口板电路原理和软件流程设计等方面均进行了较为详细的介绍。并简要介绍了不同日龄禾缢管蚜的飞行能力测试结果。对开展微小型昆虫的飞行行为学研究具有较为重要的参考价值。

A COMPUTER-MONITORED FLIGHT MILL SYSTEM FOR TINY INSECTS SUCH AS APHID

In this paper, a 32 channel, computer-monitored flight mill system fortesting the flight ability of small, weakly flying insects such as aphids was designed and presented. The flight mill construction, data collecting adapter and software design were described. The flight mill system is an optimal tool for studying small insects flight behavior. The flight ability of the bird cherry oat aphid (BCOA) Rhopalosiphum padi (Linnaeus) was tested with this flight-mill system. The results showed that the flight performance of the aphids varied with their ages. The. BCOA at 1 to 5-day old flew signifi- cantly longer than those at 7 to 9-day old. However, there was no significant difference in the average flight time among the BCOA with different ages, and the flight speed decreased with the increase of the aphid age.
