【摘要】 本研究采用机械吸捕方法,大面积捕捉草原蝗虫,全面分析研究草原蝗虫的营养成分及其被利用的可能性。研究结果表明,在草原蝗虫大量发生的地区,用机械负压吸流吸捕草原蝗虫,吸捕率可达85～90%。对蝗虫干体化验结果表明,草原蝗虫是一种高蛋白、低脂率、低含盐率并含有多种氨基酸的优质蛋白质饲料,具有很高的饲用价值。更多还原

【Abstract】 Experiments were carried out by adopting the mechanical-absorption method to catch grasshoppers in a vast area of rangelands. The nutrients of the insect were analysed. And the utilization of it was tested in many aspects. Results of our tests indicate that: 1)the mechanical negative-pressure fluid-absorption insect catcher does well in rangelands-grasshopper catching rates as high sa 85～90% ; 2)the dry matter of the grasshopper are rich of protein, amino acids,while lesser fat and low salts. It is really a pretty valuable concentrated stuff, we think.更多还原
