气吸式蝗虫捕集技术的发展与蝗虫的养殖利用

Present situation of sucking pneumatic techniques for capturing locusts and utilization of artificial raising locusts

蝗虫营养成分含量高,用途广泛,是一种很好的昆虫资源,在食用、药用、饲用等方面均有利用价值;气吸式蝗虫捕集技术在蝗虫灾害的防治和蝗虫资源的无害化捕集利用中起到重要的作用,通过对4种不同结构形式的蝗虫吸捕机的结构形式和作业特点的对比分析,找出了各自的优点和不足之处并提出了一些改进的建议,分析了每种机型所适用的作业范围。随着对蝗虫资源需求量的增大,蝗虫的网棚养殖技术也逐渐兴起、养殖规模不断扩大,通过对上述蝗虫吸捕机的分析研究,为研制一种适合于网棚内使用的小型、轻便的蝗虫吸捕机提供了参考依据。

Locust with high nutrition and widespread utilization is a kind of good insect resources. After discussing the value of locust in food, medicament and feed areas, the authors introduced the importance of the sucking pneumatic technique, which plays an important role in the nontoxic capturing for the utilization of locusts, in the prevention and control of the plague of locusts. By comparing the configurations and the performances of four types of locust-capturing machines, the authors indicated the advantages and the limitations of them, and offered some proposals for improving the characteristics of the capturing machines. With the artificial raising technology of locusts in the net house gradually popularized, the scale of the farm for raising locusts expanded continuously. The conclusions acquired by the above discussion laid the foundation for designing and manufacturing a small scale and portable machine, used in the net house, for capturing locusts.
