黄斑星天牛溴甲烷检疫熏蒸技术研究 总被引:2,自引:5,他引:2
对杨树木质包装溴甲烷熏蒸试验结果进行机率值法分析,推算出溴甲烷在4.4℃、10.0℃、15.5℃和21.1℃温度条件下达到黄斑星天牛(Anoplophora nobilis)幼虫死亡机率值9要求的CT值分别为:1133.78、938.21、642.39和349.87g.h/m^3;根据毒力试验结果进行的室内验证试验证明:在上述4个温度条件下,只要熏蒸中CT值达到了毒力测定的要求,就能够完全杀灭杨树携带的光肩星天牛(A.glabripennis)和黄斑星天牛幼虫、蛹,以及芳香木蠹蛾东方亚种(Cossus cossus orientalis)和杨干透翅蛾(Sphecia siningensis)幼虫。在此基础上,提出了木质包装溴甲烷检疫熏蒸处理的技术指标。 相似文献

黄斑星天牛的防治方法及措施 总被引:1,自引:0,他引:1
黄斑星天牛属鞘翅目、天牛科。是一种毁灭性危害的蛀干害虫,是新疆维吾尔自治区补充检疫对象。主要危害杨、柳、榆、槭等树种。由于该虫生活隐蔽,防治难度大,常造成大面积林木死亡。2003年和2005年相继在伊犁州的伊宁市和新源县发生黄斑星天牛危害杨、柳、榆、槭、李树5种树种。由于组织得力,决策果断,除治方案切实可行,黄斑星天牛得到了有效的控制。 相似文献

黄斑星天牛Anoplophora nobilis (Ganglbauer)是我国西北地区一种严重危害杨树等其他阔叶树种生长的蛀干害虫。采用化学防治等常规防治措施难度较大,利用其鸟类天敌就有着一定的积极意义。我们于1983年3~6月份,在黄斑星天牛严重发生的甘肃省清水县白驼乡境内进行了2个多月的野外调查,对黄斑星天牛的主要鸟类天敌——斑啄木鸟Dendrocopos major beicki(Stresemann)的主要生物学特性及其对 相似文献

为了探索微波处理作为木质包装替代处理方法的可能性,对不同规格和含水量的杨树木块进行微波处理试验,结果表明:频率为2450MHz的微波能够穿透厚度为10cm的杨树木材;当微波功率为900W时,规格为10cm×10cm×10cm和10cm×10cm×2.5cm的新木块中黄斑星天牛(Anoplophora nobolis)幼虫完全死亡所需时间分别为5min和2min;而干木块中则仅需3min和30s.对微波处理引起木材温度变化和水分损失以及天牛幼虫的水分损失进行了初步研究. 相似文献

Anoplophora glabripennis (Asian longhorned beetle) attacks many different broadleaf tree species. Although there is no doubt that A. glabripennis can complete its life cycle on species belonging to various genera such as Acer, Populus, Salix and Ulmus, there is conflicting information about the host plant status of many other species. Plant species may have been listed because of maturation feeding or oviposition, without evidence that A. glabripennis can actually complete its life cycle on these species. In the present review, 34 plant taxa that have been listed as A. glabripennis‐hosts are placed in four different categories based on information available through literature search and by personal communication with experts. The categories are: (I) plant species on which A. glabripennis has been reported to complete its life cycle (from oviposition to emergence of new beetles) under field conditions, (II) plant species on which A. glabripennis has completed its life cycle in laboratory or semi‐field experiments (i.e. plants and beetles reared in cages), (III) plant species on which A. glabripennis has been reported to complete part of its life cycle, and (IV) others. The following genera were placed in category I: Acer, Aesculus, Betula, Cercidiphyllum, Fraxinus, Platanus, Populus, Salix and Ulmus. The species Albizia julibrissin, Corylus colurna, Elaeagnus angustifolia, Fagus sylvatica, Koelreuteria paniculata, Malus domestica, Pyrus bretschneideri and Sorbus aucuparia were also placed in category I, although records on exit holes were limited. These species may be rather poor or unattractive hosts on which A. glabripennis may only incidentally oviposit and/or complete its life cycle or the species may be rather uncommon in outbreak areas thus far and, therefore, not frequently attacked. Elaeagnus angustifolia has also been reported to be resistant. For some of the species listed the host plant status may need confirmation. The list of category I species may also become longer in the future because several of the plant species listed only recently appeared to be true hosts, i.e. supporting completion of the full life cycle of A. glabripennis. 相似文献
