The rates of the trees damaged and the main shoots damaged by Dioryctria rubella Hampson reached 12.0% and 7.2% respectively in 5 year old plantation of Pinus massoniana. The height growth of the current year damaged main shoot was 0.1m shorter than that of the healthy main shoot. The damage rate of height growth reached 14.7%. Dioryctria sp. bored the trunk,caused the pine tree die,the tree damaged rate reached 3.2%. This paper also represents parasitic habits of two important natural enemies of insects,Macrocentrus watanabei van.Achterberg and Apanteles sp. 图表 | 参考文献 | 相关文章 | 多维度评价 Select 2. 集约经营杨树人工林中光肩星天牛不成灾原因的探讨 慕宗昭,祁学诚,尹若波,张瑞波,于加良 林业科学    1999, 35 (zk): 146-150.   摘要 （625）   HTML （0）    PDF （4045KB）（513）    可视化    收藏 The population of the glabrous spotted willow borer declines rapidly in the NAP popular intensive management plantations and the damage to farmland sheltbelts,fourside scattered grown trees and different clone plantations was got through the fixed location monitoring in Shandong Province.The result indicated that the reasons made the population of the borer declining rapidly in the intensive managed stands are the rotation period shortening eliminating pest source stands,variaties changing fast and various clones planting refraining the adaptability of the borer to poplar clones,the environmental conditions of plantations and intensive management measures destroying the suitable surroundings of the borer's reproduction and growth.The community of the borer was controlled at the lower level in NAP poplar intensive management plantations in Shandong Province. 图表 | 参考文献 | 相关文章 | 多维度评价 被引次数: Baidu(2) Select 3. 光肩星天牛危害程度与经营水平的关系及其发生期预测 茹桃勤,李向东,宋宏伟,孙金钟,宋小菊 林业科学    1999, 35 (zk): 143-145.   摘要 （597）   HTML （0）    PDF （1895KB）（527）    可视化    收藏 This paper reports the relationship between the outbreak of Anoplophora glabripennis (Motsch.) and management level of poplar forests,the selection of laying eggs to the thickness of host and the prediction of adults and larvae occurrence period. The result showed that damaged level of street trees is the most serious,and that of fast growth and high quality forests is the most slightly,the damaged rates of them are 85% and 7% respectively. The most suitable thickness of branch for adults laying eggs is 8~16cm. The emergence peak of adults is from 20 July to 20 August,it is the most suitable period to control adults. The hatching peak of larvae is from 20 August to 20 September,and this is the most appropriate period to control larvae. 图表 | 参考文献 | 相关文章 | 多维度评价 被引次数: Baidu(1) Select 4. 主要用材树种新造丰产林地病虫害定位观测结果综合分析 兰再平,程红,吴金坤,苏显峰 林业科学    1999, 35 (zk): 128-142.   摘要 （810）   HTML （0）    PDF （7733KB）（522）    可视化    收藏 本文对设置在世界银行贷款“国家造林项目”16个项目省(区)内15个主要用材树种新造速生丰产林林地上的62个病虫害定位观测点上连续5年观测取得的资料和数据进行了综合分析。分析结果表明,除日本落叶松没有发生任何病、虫害以及白榆、刺槐和加勒比松没有发生病害外,其余树种造林地都不同程度地发生了病虫危害。相比之下,马尾松、火炬松、毛白杨、欧美杨造林地发生虫害种类较多;马尾松、火炬松、毛白杨、欧美扬、刚果12桉和蓝桉造林地发生病害种类较多。根据各种病虫害在同一树种所有观测点上的样点发生频率和观测发生频率,作者提出了各树种造林地的最常发生虫害和病害种类。在所有病虫害观测点进行的全部观测中,虫害观测占77.7%,病害观测占27.1%。在全部有虫观测中,发生重度危害的观测为极少数,仅占2.5%,发生中度危害的观测也较少,占8.86%,绝大多数观测为轻度危害;同样,在全部有病观测中,发生重度危害的观测为极少数,仅占6.08%,发生中度危害的观测为少数,占11.6%,绝大多数观测为轻度危害。所以,总体来讲,病虫害给主要用材林树种幼林造成的危害较轻。建议根据本文提出的各树种常发性和造成严重危害的病虫害种类,有重点地制定防治措施。 图表 | 参考文献 | 相关文章 | 多维度评价 被引次数: Baidu(2)
