黑肩绿盲蝽Cyrtorhinus lividipennis Reu(?)er是我省水稻主要害虫稻飞虱和稻叶蝉的重要捕食性天敌。关于黑肩绿盲蝽的研究报道较多;但有关其空间分布型的研究未见报道。为此,我们于1989年对该虫的空间分布型进行了研究,以便为其种群消长及科学的抽样提供理论依据。 调查方法 我们于1989年8月中旬在贵州铜仁市川硐区白水乡,选择好中差三种类型的稻田10块进行调整。在各调查田的中央连片调查1000丛,记录每丛上的成、若虫数。根据各田的调查
Cyrtorhinus lividipennis Reu (?) Er is a major predator of paddy rice planthoppers and rice leafhoppers in our province. There are many reports on Apodemus agrarius; however, no studies have been reported on its spatial distribution. To this end, we conducted a study on the spatial distribution of the pest in 1989 to provide a theoretical basis for its population growth and scientific sampling. Method of investigation We were in mid-August 1989 in Baishui Township, Tongren District, Tongren City, Guizhou, choose to make a difference of three types of paddy fields to adjust 10. A total of 1000 plexuses were surveyed in the central part of each survey field, and the number of adult and nymphs on each plexus was recorded. According to the field investigation
