清远麻竹笋沟金针虫生物学特性及其土壤空间分布

Investigation Biological Characteristics of Qingyuan Pleonomus elegans of P. canaliculatus and Their Spatial Distribution in Soil

为提高清远麻竹笋的产量,对清远地区麻竹笋沟金针虫(Pleonomus canaliculatus)的危害进行调查,并对其生物学特性进行描述。调查发现沟金针虫是清远地区麻竹笋退笋的主要害虫。据沟金针虫幼虫在麻竹笋土壤的空间分布表明:体型较大的沟金针虫在麻竹笋土壤中的分布主要为聚集分布。鉴于沟金针虫危害的竹笋比以往报道的有扩大趋势,在竹种移植、土壤改良等方面要加以考虑。

In order to improve P. elegans production in Qingyuan, Pleonomus canaliculatus in Qingyuandamage were investigated, and its biological characteristics were described. The survey found Pleonomuscanaliculatus was the main pest of P. elegans out shoot in Qingyuan area. According to wireworm larvae in P.elegans the spatial distribution of soil showed that： the distribution of larger wireworms in P. elegans in soilmainly aggregated distribution. In view of wireworm harm shoots than in previous reports had a tendency toexpand, in bamboo transplanting, soil improvement to be considered.
