稻黑蝽Scotinophora lurida Burmeister已连续几年在南方稻区严重发生,成为水稻分蘖期和穗期的重要害虫,并有逐渐加重之趋势,严重威胁水稻生产,为了做好该虫的测报和防治工作,必须采用合理的抽样技术,才能正确估计该虫的田间种群密度。为此,首先要弄清该虫的空间分布型。基于这一目的,我们于1986年晚稻分蘖期对稻黑蝽成虫的空间分布型进行了测定。
Scotinophora lurida Burmeister has been seriously impacted in the southern rice area for several years and has become an important pest at the tillering and heading stages of rice with a tendency of gradual aggravating, which is a serious threat to rice production. In order to do a good job in reporting and controlling the insects, , We must use reasonable sampling techniques to correctly estimate the pest population density in the field. To this end, we must first understand the spatial distribution of the worm. For this purpose, we determined the spatial distribution of adult rice black bugs in the late rice tillering stage of 1986.
