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

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.
