Abstract

Abstract We analyzed nitrogen (N) content in phloem and xylem of 75 northern red oak, Quercus rubra L. (Fagaceae), removed in 2002–2007 from three sites within the Ozark National Forest, Arkansas, to investigate the relationship between vascular tissue N status and wood borer infestation. Populations of native red oak borer, Enaphalodes rufulus (Haldeman) (Coleoptera: Cerambycidae), experienced an outbreak and population crash during the sampling period. Vascular tissue N was not correlated with borer infestation density (exit holes/m-2/bark surface), which suggests variation in N status of vascular tissue was not influenced by or did not influence borer success. Vascular tissue N was greater in trees sampled during winter months than in trees sampled in spring and summer months.

黑桫椤侵染下黑桫椤韧皮部和木质部氮的变异

摘要/ Abstract摘要:本研究分析了2002 ~ 2007年在美国阿肯色州奥扎克国家森林3个采伐点采伐的75棵北方红橡树(壳斗科)韧皮部和木质部的氮含量，探讨了维管组织氮含量与木蛀虫侵染的关系。当地红橡树螟虫(鞘翅目:天牛科)种群在采样期间发生了暴发和种群崩溃。维管组织氮含量与螟虫侵染密度(出口孔数/m-2/树皮表面)无关，说明维管组织氮含量的变化不受螟虫成功与否的影响。维管组织氮在冬季取样的树木中高于春夏季取样的树木。

期刊介绍： French translation follows/le français suit Published since 1868, this peer-reviewed bimonthly publication is the official journal of the Entomological Society of Canada. Available via the internet and with hardcopy distribution to 55 countries, its research papers and notes are relevant to entomologists and other biologists around the world. In addition to being a venue for topical reviews and forum discussion, The Canadian Entomologist publishes current research in all facets of entomology, including systematics and morphology, molecular and developmental biology, ecology and behaviour, biodiversity and evolution, insect management, entomological techniques, and other relevant subject areas. Contributions are published in English or French. Authors will not pay page charges, and will experience fast, high quality reviews of their papers.Publiée depuis 1868, cette publication bimestrielle avec comité de lecture est la revue officielle de la Société d’entomologie du Canada.
