玉米螟是危害玉米等多种作物的重要害虫。过去国内外一直认为玉米螟的卵块在玉米上的空间分布属于随机分布型(Poisson distribution)。在此基础上,我国一直采用大五点100株的抽样技术,调查玉米螟的种群动态,并进行科学研究和指导生产。根据我们多年在农村从事教学、科研和生产的观察,发现玉米螟卵块在玉米田的分布与 Corn borer is an important pest that can endanger corn and other crops. In the past, the spatial distribution of the eggs of corn borer in corn has always been considered as a Poisson distribution. On this basis, China has been using the Big Five 100 sampling techniques to investigate the population dynamics of corn borer, and conduct scientific research and guide the production. According to our many years of teaching in the rural areas, research and production of observation, found that corn borer eggs in the corn field distribution and
