The occurrence of tne apple buprestid(Agrilus malt Mats.)was first found in Fenghsien CountyShensi,in April,1974.After a prelminary investigation, the pest has been found to be distributed in such counties as Fenghsien,Liupa,Taipai and such municipalities as Paochi(regions along the weiho River)and Tungchuan. The total area of occurrence is estimated to be 15,000 mu. It has one generation a year in Fenghsien County and overwinters chiefly as mature larvae.The peak of emergence is around the middle of June.The adults are attractaed by lights but weak in flight and they show a poisson type of distribution witnin the scope of the orchard.The wilting of branches and the dying of whole trees are closely related to larval density and to the type of their distribution,but the process can be accelerated by the accompanying diseases of rotting. The apple buprestid was principally a pest of Malus prunifolia Borkn., Mains yunnanensis Schneid.,and other wild trees,but it has migrated into apple since the establishment of orchards on mountain slopes.In view of the fact that this pest is an indigenous species of China and Korea,that it is difficnlt to conduct control on wild trees and that it has spread to most of the northern orchards,it is proposed that the apple buprestid should no longer be a quarrantine object. Against this pest integrated control should be adopted,when a new orchard is to be established,the site should be selected where ther are no wild hosts.Integrated control measures are pariculary important for the adult and larval stages,protection of parasites and utilization of woedpeckers are significant.

1974年4月在陕西省凤县首先发现了苹果小吉丁虫。现巳初步查明在陕西的分布区有3县2市,即凤县、留坝、太白、宝鸡市(渭滨区)和铜川市,为害面积约一万五千亩。苹果小吉丁虫在凤县一年发生一代,主要以老熟幼虫越冬,成虫集中羽化期为6月中旬。成虫喜光,飞迁力不强,在一个果园多呈核心分布,幼虫引起枯枝死树除和幼虫密度和分布形式有关外,诱致腐烂病发生则加速了死亡。苹果小吉丁虫只分布在我国和朝鲜,是当地楸子、滇池海棠等原有害虫,苹果栽植后,逐渐飞迁到苹果树为害。不宜继续列为国内检疫对象。防治苹果小吉丁虫,要采取综合措施,建园时要选择附近没有野生寄主的地方,加强成虫期和幼虫期的防治,保护寄生蜂,招引啄木鸟。

This paper takes Xichou cone karst area as an example to discuss the characteristics of ecological environment in karst area of southeastern Yunnan. We have analysed the physico-chemical features and the component fatty acid of seed oil of Sapium rotundifolium (Euphorbiaceae), a common wild tree in karst area. In Xichou, although the climate is wet, but limestone hill region has a low level of water-retention properties, "Ground layer dry" is one main character of natural environment, and water- soil erosion...

This paper takes Xichou cone karst area as an example to discuss the characteristics of ecological environment in karst area of southeastern Yunnan. We have analysed the physico-chemical features and the component fatty acid of seed oil of Sapium rotundifolium (Euphorbiaceae), a common wild tree in karst area. In Xichou, although the climate is wet, but limestone hill region has a low level of water-retention properties, "Ground layer dry" is one main character of natural environment, and water- soil erosion has become an important environmental problem.

本文以云南省西畴石灰岩峰丛地区为例探讨了滇东南喀斯特生态环境的特点;同时应用气相色谱对石灰岩地区较为常见的乡土树种圆叶乌桕进行了种子油理化性质及脂肪酸成分分析。认为圆叶乌桕在石灰岩地区有较好的环境适应性,生长迅速,其种子含油量高、材质好、并兼有其它用途,在生态环境严酷、资源贫乏的石灰岩地区是理想的开发利用树种。
