众所周知,植物果实在贮存过程中造成损失的一个重要原因就是蛀虫的滋生和繁殖。据统计,美国在这方面的经济损失每年可高达总收益的9％。在有虫源的粮食中,如果不加以控制,六个月内就可使其在重量上损失30％,并使70％的粮食粒中生有蛀虫。蛀虫在幼龄期的大部分时间里藏在果实(谷物及水果)内,肉眼难以发现。传统的检测手段是对米粒或水果进行抽样解剖统计,或用X射线、红外线、CO_2探测等方法,或者干脆让样品中的蛀虫生长成成虫后进行统计。这些方法一般工作量大、设备昂贵或周期太长。
It is well-known that one of the important causes of the loss of plant fruits during storage is the growth and reproduction of moth worms. According to statistics, the U.S. economic losses in this regard can be as high as 9% of the total revenue each year. Insect-derived food, if left unchecked, can lose 30% of its weight over six months and can cause about 70% of food grains to have moths. Borers hide in the fruits (grains and fruits) most of their young life, making them hard to see with the naked eye. The traditional detection method is to sample the grain or fruit for anatomical statistics, or to use X-ray, infrared ray, CO_2 detection method or simply to make the sample borers grow into adults after statistics. These methods are generally heavy workloads, expensive equipment or long periods.
