带岭新松叶蜂在辽宁抚顺地区主要危害油松和赤松,一年发生1代,以卵越冬,其卵期长达6个多月,是主要的调查虫期。为了给卵期调查方法的确定提供理论依据,进行了叶蜂卵在油松树冠上分布规律的研究。结果表明,叶蜂卵在油松树冠上呈聚集分布,且在树冠不同方位的分布无显著差异,但在树冠不同层次的分布差异显著。
Bringing new pine bumblebee in Liaoning Fushun major hazards Pinus tabulaeformis and Pinus thunbergii, occurs a generation a year, the overwinter eggs, the egg period of up to 6 months, is the main survey of worm stage. In order to provide a theoretical basis for the determination of the method of egg stage investigation, the distribution of leaf eggs in the canopy of Pinus tabulaeformis was studied. The results showed that the leaf eggs were aggregated and distributed in the canopy of canopy. There was no significant difference in the distribution of canopy in different directions, but there were significant differences in the distribution of canopy at different levels.
