1遥感技术在森林病虫害监测中的应用研究进展显示文摘总结了近50年来遥感技术在森林病虫害监测领域的研究进展。将近年来遥感监测病虫害的主要方法归纳为影像分类法和影像差技术法,遥感监测森林病虫害的模型概括为3种主要应用模式:1)各类植被指数形式模型;2)采用所用通道的其他组合形式模型;3)各通道与生态因子的混合形式模型。根据分析研究提出了今后遥感监测森林病虫害研究的4个主要方向:1)热红外波段监测森林病虫害的应用研究;2)森林病虫害遥感监测物理模型的研究;3)森林病虫害遥感监测的基础理论研究;4)高光谱、高空间和高时间分辨率遥感数据的应用研究。王蕾 骆有庆 张晓丽 马钦彦 Kari Heliovaara 贾林强 2008世界林业研究2008,21,5:11
2阿尔山落叶松主要蛀干害虫的种群空间生态位显示文摘对阿尔山落叶松主要蛀干害虫的种群生态位进行了研究,结果表明:在落叶松衰弱立木上,生态位宽度以落叶松八齿小蠹最高,在中龄和老龄树上分别达到0.5782、0.5498,在落叶松中龄和老龄枯死立木上,白带长角天牛的空间生态位宽度分别达到0.5143、0.6294,分布较衰弱木广,而云杉大黑天牛空间生态位宽度在衰弱和枯死立木上都最低。落叶松立木上的空间生态位重叠指数以落叶松八齿小蠹对其他3种优势天牛偏高,天牛之间的空间生态位相似性比例指数均较高且差距较小,说明4种害虫对空间生态位的占据有很大相似程度。4种害虫的空间种间竞争系数均很大,说明对空间和资源的竞争非常激烈,在这种情况下4种害虫能够共存,根本原因是由于取食部位的分化。袁菲 骆有庆 石娟 Kari Heliovaara 2011生态学报2011,31,15:9
3Damage characteristics of three boring pests in Artemisia ordosica显示文摘The population density and distribution of the three major boring pests,Holcocerus artemisiae,Sphenoptera sp.and Adosopius sp.were studied in their host plant Artemisia ordosica.Results show that the larvae of H.artemisiae mainly bore the rhizome of A.ordosica,but also the larvae of Sphenoptera sp.and Adosopius sp.bore the rhizome of A.ordosica.The adults of Sphenoptera sp.and Adosopius sp.feed on the leaves of A.ordosica as a nutritional supplement.The distribution of the larvae of three pests in their host plant is completely different.H.artemisiae and Sphenoptera sp.are distributed in the whole A.ordosica plant.The newly hatched larvae first feed on the phloem and xylem of stem and then burrow to the roots before the winter of the same year.However,Adosopius sp.is distributed mainly in the roots.The newly hatched larvae move from the phloem to the xylem,and gradu-ally damage the lower part of the trunk.The larvae of the three pests sometimes coexist in a single A.ordosica plant.However,the probability of the coexistence of the three pests is very small.The highest probability of coexistence of two pests was observed in Sphenoptera sp.and H.artemisiae,while the probability of coexistence of Sphenoptera sp.and Adosopius sp.as well as H.artemisiae and Adosopius sp.was smaller.The reasons for coexistence or its avoidance are not only related to the amount of food pro-vided nor the volume of larval living space in a single A.ordosica plant,but also related to the development characteristics of different kinds of larvae and interspecific competition.ZONG Shi-xiang LUO You-qing CUI Ya-qin WANG Jian-wei YAN Wei LIU Ai-jie Kari HELIOVAARA 2009Forestry Studies in China2009,11,1:3
4不同含量引诱剂对落叶松八齿小蠹及其天敌红胸郭公虫的引诱(英文)显示文摘在内蒙古阿尔山的田间诱捕试验中,落叶松八齿小蠹引诱剂1共诱集到16头落叶松八齿小蠹和1319头天敌红胸郭公虫,而落叶松八齿小蠹引诱剂2诱集到24104头落叶松八齿小蠹和776头红胸郭公虫。室内的触角电位试验结果表明:落叶松八齿小蠹对引诱剂2的触角反应(雌虫2.139mV±0.678mV,雄虫2.169mV±0.473mV)大于引诱剂1(雌虫0.440mV±0.232mV,雄虫0.297mV±0.142mV),对引诱剂1的反应值和对照差不多;而红胸郭公虫对引诱剂1的触角反应(雌虫4.618mV±1.106mV,雄虫4.534mV±1.087mV)明显大于引诱剂2(雌虫2.209mV±0.680mV,雄虫1.953mV±0.601mV),对引诱剂2也有一定的反应值。触角电位试验与田间诱捕试验结果相符合。GC-MS分析结果表明:引诱剂1的主要成分为3.06%的cis-geraniol,1.98%的Ipsenol,80.36%的(S)-cis-verbenol和1.03%的1-verbenone;结合卖方公司提供的数据,引诱剂1的主要成分为4.78%的2-methyl-3-buten-2-ol,63.71%的Ipsenol(纯度为96.9%),1.46%的Cedrene和22.42%的Isocaryophillene。结合以上数据分析得出:不同成分引诱剂对落叶松八齿小蠹及天敌红胸郭公虫引诱能力显著不同,Ipsenol对诱集落叶松八齿小蠹起重要作用,而(S)-cis-verbenol则对诱集天敌红胸郭公虫起重要作用。袁菲 骆有庆 石娟 Kari Heliovaara 2012林业科学2012,48,6:2
5落叶松八齿小蠹坑道在落叶松立木上的垂直分布特征显示文摘应用多个聚集度指标和Iwao,Taylor等的回归分析法对落叶松八齿小蠹Ips subelongatus Motschulsky坑道的垂直分布型进行了研究。结果表明:落叶松八齿小蠹坑道数量与落叶松树干不同高度变化成线性关系,拟合的直线方程为y=-10.867x+92.884;落叶松八齿小蠹坑道基本属于均匀分布;坑道的分布与落叶松立木阴面和阳面关系不大。最后确定了不同落叶松八齿小蠹坑道密度下的最适抽样数。袁菲 骆有庆 石娟 Kari Heliovaara 2011应用昆虫学报2011,48,4:2
