【目的】葡萄座腔菌科菌物是引起众多经济及生态造林树种枝干溃疡、枝枯类病害的病原生物,在世界各地均有广泛的分布。本研究对河北省内,与经济林木病害相关的葡萄座腔菌科菌物进行系统分类研究,目的在于揭示该科菌物在特定地区的地理分布特征,明确该类菌物所致树木枝干溃疡、枝枯类病害的寄主植物范围,为河北省树木溃疡、枝枯类病害的控制提供理论依据。【方法】在对河北省树木溃疡类病害系统调查的基础上,本研究根据菌物无性型及有性型的形态学特征、rDNA-ITS序列特征对包括河北省石家庄在内的8个市(县、区)25个不同地点的葡萄座腔菌科菌物进行分类鉴定和系统分类。【结果】共获得葡萄座腔菌科菌物5种73株,分别属于Botryosphaeria dothidea、B.stevensii、B.obtusa、B.sarmentorum和Phyllosticta citrichinaensis。其中B.dothidea为河北省葡萄座腔菌科优势菌物种,占全部检出菌物菌株总数的77%。葡萄座腔菌科菌物侵染杨树、柳树、苹果、核桃等28种植物,其中包括大叶黄杨、构树、火炬树、连翘、花椒和刺梅等6种新寄主植物。【结论】B.dothidea不仅危害杨树等传统寄主,而且危害花椒等新寄主植物以及入侵树种火炬树,是危害河北省树木健康生长的最为重要、分布最为广泛的枝干病原菌物,有必要对其溃疡致病性分化和种群遗传分化进行深入分析。来自柿树、花椒等寄主的10个具有Dothiorella型分生孢子的菌株形成单系类群,提示这些菌株可能是与B.sarmentorum和B.iberica不同的一个系统发育学新种。 相似文献

Asemini is a Northern Hemisphere cerambycid tribe,and an important forest pest, mainly causing damage to coniferous plants.More important,as one kind of quarantine insects,Asemini can bring about many troubles in timber trade, therefore,the alien species should be paid more attentions and need to be quarantined in order to prevent them to be introduced to China.In China, there are 4 genus 26 species of Asemini.Host plants of Asemini include 15 genus 36 species of 7 families, and the main host plants are in Pinus,accounting for 30.56%of the total.A fauna analysis indicated that 15 species of Asemini distributed in the Palareartic Realm,accounting for 57.69%of the total. The species predominated in China,probably because gymnosperms were the main vegetable type in this region.This paper lists all the known species and genera of Asemini and their host plants in China,and discusses their distribution.The aim is to arouse the concerns of these insects and provide a reference for the relevant work. 相似文献

幽天牛族是一类重要的林业害虫,我国已记载昆虫4属26种.幽天牛族昆虫的寄主多为针叶类裸子植物,已记载的寄主植物有7科15属36种,其中以松科松属的种类最多,占所有记录到种的寄主植物的30.56%,而且危害松属的幽天牛数量也最多.对我国目前分布的26种幽天牛族昆虫进行区系分析,发现幽天牛族昆虫以古北区成分为主,这可能与古北区针叶植物较多有一定关系.我国的地理环境及生态植被,均可以满足幽天牛族非中国种的分布及寄主需求,非常适宜幽天牛族非中国种的生存和繁衍,因此应该提高警惕,严防国外种类传入我国,以保护我国树木安全. 相似文献

The results of the monitoring of Thysanoptera species on cultivated plants in Slovenia (2000–2001), Croatia (1994–1996), and
Serbia and Montenegro (1988–2003) are presented in this study. The aim of the investigation was to study the host plant distribution
of the predator Aeolothrips intermedius Bagnall and its potential prey. Banded thrips were found on 30 different host plant species belonging to 16 botanical families,
always in mixed populations with phytophagous or facultative phytophagous insects (including 18 Thysanoptera species). On
the vegetative parts of the cultivated plants, banded thrips were found less numerous in spite of the massive population of
some harmful thrips species. This indicates highly important role of pollen as alternative food for Aeolothrips intermedius. 相似文献
