金银花2种蛀干性害虫的发生特点与防治方法 总被引：1，自引：0，他引：1
金银花为我国名贵中药材。其性寒味甘,具有清热解毒、活血化瘀,凉散风热之功效,被称为植物广谱抗生素。在封丘县,金银花已有1500年以上的栽培历史。近年来,随着国内、外对金银花需求量的不断加大,种植面积在逐年增加,目前,全县种植面积已达2万hm2。种植面积的增加,改变了蛀干性害虫的生态条件,使其发生呈上升趋势。为控制蛀干性害虫的为害,笔者进行了试验研究。现就咖啡脊虎天牛及芳香木蠹蛾等为害金银花的2种蛀干性害虫发生特点和防治方法报告如下:1咖啡脊虎天牛(Xylotrechus grayii White)1.1形态特征体长9.5～15mm,体宽2.5～4.5mm,黑色… 相似文献

对我国用于防治林木蛀干害虫的重要天敌昆虫类群--肿腿蜂科硬皮肿腿蜂属Sclerodermus Latreille 1809的种类进行了订正性研究。研究表明,目前我国硬皮肿腿蜂属共有4个种,分别是管氏肿腿蜂Sclerodermus guani Xiao et Wu 1983,川硬皮肿腿蜂S. sichuanensis Xiao 1995,海南硬皮肿腿蜂 S. hainanica Xiao 1995和白蜡吉丁肿腿蜂S. pupariae Yang et Yao 2012,另有1疑似分布种--哈氏肿腿蜂S. harmandi Buysson 1903。编制了区分这5个种的检索表。研究认为,日本和韩国专家将我国的管氏肿腿蜂更名为哈氏肿腿蜂（作为同物异名）是不合适的,管氏肿腿蜂应为一个有效种。对管氏肿腿蜂根据模式标本进行了再描述,提供了形态特征照片图;也引述了日本学者Terayama（2006）对哈氏肿腿蜂的再描述,以便区分这两个种。并以对照表的形式,给出了区分这两种的主要形态特征。同时也对作者2012年发表在美国的Annals of the Entomological Societuy of America 上的新种--白蜡吉丁肿腿蜂做了简要描述,附有该种的形态特征照片图,并记述了该种的生物学、行为学特性,以便国内学者鉴定该种时参考。研究发现白蜡吉丁肿腿蜂也寄生栗山天牛Massicus raddei、光肩星天牛Anoplophora glabripennis、锈色粒肩天牛Apriona swansoni、咖啡脊虎天牛Xylotrechus grayii和白蜡窄吉丁Agrilus planipennis及苹小吉丁A. mali等我国多种重要的林木蛀干害虫,是一种可利用于防治这些害虫的优秀天敌。 相似文献

白蜡窄吉丁Agrilus planipennis Faimaire原分布在东北亚国家,包括俄罗斯远东地区,在原产地由于为害不重而受关注度不高,因此没有被列入世界各国危险性有害生物监测重点名单之中。但自21世纪初其传入美国和加拿大之后,已造成重大灾害,成为迄今为止北美地区危害性最大和造成经济损失最为严重的外来入侵森林害虫。由于该害虫的高度隐蔽性,在传入地的早期检测非常困难,发现该虫的地点往往其种群已经定殖多年,因此根除策略难以奏效。美国在白蜡窄吉丁入侵初期进行的根除策略失败后迅速启动了生物防治计划。通过国际合作研究,美国从中国引进了3种寄生性天敌:白蜡吉丁柄腹茧蜂Spathius agrili Yang、白蜡吉丁啮小蜂Tetrastichus planipennisi Yang和白蜡吉丁卵跳小蜂Oobius agrili Zhang & Huang,经大量人工繁殖后在林间进行了释放,现已在当地成功建立了天敌种群,开始发挥越来越重要的控制作用。本文对最近10多年来白蜡窄吉丁生物防治方面的研究进展进行了回顾和简要综述,希望对我国同类蛀干害虫的研究工作有所启示。 相似文献

油松Pinus tabulaeformis Carr.是沈阳地区主要的造林和绿化树种,为了明确沈阳市松材线虫病首发地油松蛀干害虫的发生情况,摸清其寄生性天敌昆虫的种类,2019年3月至2019年10月,本研究使用木段解剖法和林间木段套笼饲养法对沈阳市东陵公园油松蛀干害虫及其寄生性天敌的种类、羽化期和在树干上的垂直分布情况进行了研究。3月对油松松材线虫病采伐疫木的解剖发现了3种天牛幼虫;4—10月从养虫笼木段中持续收集羽化的蛀干害虫和寄生蜂成虫共4科（亚科）11种,其中天牛科4种,小蠹亚科3种,寄生蜂4种。蛀干害虫的分布优势排序依次为黄色梢小蠹Cryphalus fulvus Niisima、横坑切梢小蠹Tomicus minor（Hartig）、松皮天牛Rhagium inquisitor（Linnaeus）、褐梗天牛Arhopalus rusticus（Linnaeus）、小灰长角天牛Acanthocinus griseus（Fabricius）、红松根小蠹Hylastes plumbeus Blandford和脊鞘幽天牛Asemum striatum（Linnaeus）;寄生蜂的分布优势排序依次为始刻柄茧蜂Atanycolus initiator（Fabricius）、柄腹茧蜂Spathius sp.、定山皱背姬蜂Rhyssa jozana Matsumura和黑角拟皱姬蜂Pseudorhyssa nigricornis（Ratzeburg）。疫木解剖试验发现松皮天牛和小灰长角天牛的幼虫在树干不同部位的虫口密度没有明显差异,而褐梗天牛的幼虫在基部虫口密度最大,与中部和端部的差异极显著。套笼蛀干害虫及寄生蜂羽化成虫的垂直分布规律研究发现,黄色梢小蠹在油松树干中、上部占据生态位优势,横坑切梢小蠹在2.0～4.0 m的油松树干数量最多,小灰长角天牛和松皮天牛在油松树干各个高度分布相对均匀,褐梗天牛在油松树干下部占据生态位优势,始刻柄茧蜂数量最多,以0.0～4.0 m的范围最多;柄腹茧蜂在4.0～10.0 m的范围较多。本文明确了沈阳市东陵公园油松蛀干害虫及天敌的发生情况,对于指导本地蛀干害虫防治和进一步开发利用昆虫天敌资源都具有重要的意义。 相似文献

The emerald ash borer, Agrilus planipennis , is a beetle native to East Asia where it is considered a minor pest, preferentially attacking weakened or dying ash trees. It was first discovered in North America in 2002 and has since become one of the most serious invasive insect pests, killing millions of healthy ash trees in urban and forested settings. Similar damage is now occurring in the region of Moscow, Russia, which causes serious concern for Europe. In this paper, we review the current knowledge on A. planipennis in Asia and North America, provide new information on its occurrence in the region of Moscow and Eastern Russia and make recommendations for research and management strategies in Europe. 相似文献

为了解影响白蜡窄吉丁自然种群的关键因子,本研究对影响白蜡窄吉丁自然种群的所有生物和非生物因素进行了主成分分析,并进一步拟合了白蜡窄吉丁幼虫数量与寄主植物、树干胸径的关系。结果显示,寄主植物抗性是影响白蜡窄吉丁自然种群最主要的因素,中国本土白蜡树种水曲柳的受害情况远低于美国栽培品种绒毛白蜡,且不同寄主植物间的幼虫数量差异显著;林分结构的影响作用次之,白蜡纯林的受害程度高于混交林。年极端低温、年极端高温、幼虫期和卵期的寄生率对白蜡窄吉丁的影响作用也比较重要。研究结果为生产上采用栽培抗性树种和在合适时期释放天敌控制白蜡窄吉丁的为害提供了理论依据。 相似文献

After the December 1999 storms, two networks were set up over 2 years (2000 and 2001) to assess the scale and type of insect colonisation on storm damaged trees and to interpret these events for the future. The Level 1 network, was a large-scale survey that covered the entire storm area and provided qualitative observations on its 898 plots in which every major tree species was assessed. The Level 2 network, was a regional survey set up only in two regions: the 'Landes' region and the Northeast of France. The observations were intensive and quantitative, devoted only to maritime pine in the 'Landes' region and to Norway spruce in the Northeast of France. The Level 1 network indicated that less than 40% of the storm damaged trees were colonised by bark beetles in September 2000. No attacks were observed on standing trees in 2000 but many occurred during 2001 in spruce and maritime pine stands. The Level 2 network in the Vosges mountains showed a late colonisation in October and November 2000. The emerging population of Ips typographus on attacked trees reached 25 000–30 000 insects/m3. This huge population combined with the low rate of parasitism in 2001 leads to the expectation of increasing damage in spruce stands next year. 相似文献

Xylotrechus chinensis belongs to the entomofauna of China, Japan, the Korean Peninsula and Taiwan. Prior to this paper it has been intercepted twice outside its native range, once in Philadelphia (USA) and once in Germany (Europe). In spring 2017, it was detected for the first time in Greece, in Heraklion city (Island of Crete) infesting the trunk of trees of Morus species planted near the harbour of the city. It can thus be hypothesized that X. chinensis was transported from its native range with commodities that are handled in the harbour. Eradication efforts are being taken in order to prevent its further spread, which could threaten several other tree species because X. chinensis attacks a wide range of hosts. This is the first record of this pest from the EPPO region. 相似文献

BACKGROUND: Azadirachtins are natural insecticides derived from the neem tree. The emerald ash borer (EAB) is an exotic invasive insect pest that infests various ash tree species and has the potential for significant economic, aesthetic and ecological impacts throughout North America. The initial translocation and foliar residue dynamics of azadirachtins were examined following direct injection into white and green ash trees growing in urban scenarios as a potential control for EAB. RESULTS: Substantial concentrations of azadirachtins A and B [mean maxima > 0.98 mg kg?1 fresh weight (f.w.)] were observed within 2 days of injecting a specifically designed formulation of azadirachtins. Foliar residues declined exponentially through time, with half‐life estimates ranging from 5.1 to 12.3 days. At the time of leaf senescence, foliar residue levels approximated 0.01 mg kg?1 f.w., strongly mitigating the potential effects of non‐target biota in soil or aquatic compartments. CONCLUSION: The magnitude and duration of exposures observed in this field study were considered to be above the thresholds required for biological effectiveness against both larval and adult life stages of EAB. Results support the use of azadirachtins as an environmentally acceptable systemic insecticide for control of EAB and protection of high‐value ash trees in urban environments.
