竹叶螨对毛竹危害的研究

Damage of Spider Mites on Bamboo Leaf of Phyllostachs pubescens

本文报道了南京裂爪螨 Schizotetranychus nanjingensis Ma et Yun、竹缺爪螨 Aponychuscorpuzae Rimando和锈螨 Eriophyes sp.的混合危害对毛竹光合作用和竹叶生长量的影响。研究结果表明 ,受害 5级竹叶片的叶绿素含量、光合作用强度和生长量分别下降 51.55%、79.6 %和 72 .6 %。新生竹叶明显变少、变小。受害程度愈重 。

Influence on the photosynthesis and increment of bamboo leave damaged by mix populations of Schizotetetranychus nanjingensis Ma et Yun, Aponychus corpuzae Rimando,Eriophyes sp. is reported.The results are shown that the amount of chlorophyll,pure photosynthesis intensity,and increment of bamboo leave of 5-grade damage is reduced by 51.55%,79.6% and 72.6% respectively. The new bamboo leave become less and smaller evidently, the more serious the degree of damage is,the more evident it shows.
