Normally the leaves of broad leaf plant release small amount of volatile compounds, but after feeding damaged by herbivorous insects large amount of volatiles is released, and the profile of the emitted volatiles is markedly different from those of undamaged plants. These volatile compounds play an important role in the relationship among the plants, herbivorous insects and their natural enemies.

Normally the leaves of broad leaf plant release small amount of volatile compounds, but after feeding damaged by herbivorous insects large amount of volatiles is released, and the profile of the emitted volatiles is markedly different from those of undamaged plants. These volatile compounds play an important role in the relationship among the plants, herbivorous insects and their natural enemies. To further understand the releasing mechanism of the volatile compounds from plants feeding damaged by herbivory, ashleaf maple ( Acer negundo ) and Anoplophora glabripennis Motsch. were used as experiment materials. The feeding time was 72 hours. The volatile compounds were detected by GC MS. The emission rate of most volatile compounds reached the first peak 9 hours after the ashleaf maple was infested except decanal, β pinene, hexahydrofarnesyl acetone, phenethyl acetic acid, methyl benzoic acid, methyl salicylate and syn 2 methyl butyl aldoxime. After then they decreased for a while, and then increased gradually and reached the maximum at 48 hours. However, the emitted amount of β pinene, 3 carene, eucalyptole, D limonene, eucalyptole, trans geranyl acetone, methyl benzoic acid, acetophenone and benzothiazole reached the top at 72 hours whereas syn 2 methyl butyl aldoxime, 1,3,3 trimethyl 2 methylene indoline reached the top only 1 hour after the plant was feeding damaged. After feeding damage, the sorts of the volatiles induced only by A. glabripennis were gradually increased and finally reached to 17 at 48 hours.

阔叶植物叶片通常释放少量的挥发物 ,但是当受到害虫取食后植物会释放大量的物质 ,并且其挥发物的指纹图谱与未被损伤的植株相比大不相同 .这些挥发物在植物 -害虫 -害虫天敌之间的关系中起着非常重要的作用 .为了进一步了解昆虫取食植物后挥发物的释放机制 ,作者选用复叶槭 (Acernegundo)和光肩星天牛 (Anoplophoraglabripennis (Motsch .) )为试验材料 ,利用气相色谱和质谱联用 (GC MS)检测挥发物 .在天牛取食后大多数物质在 9h的释放率达到第一个峰值 (β 蒎烯、六氢法尼烯基丙酮、乙酸苯乙酯、苯甲酸甲酯、水杨酸甲酯、syn 2 甲基丁醛肟除外 ) .在经过短时间下降后又逐渐上升 ,至天牛取食后 48h达到最大值 .只有 β 蒎烯、3 蒈烯、桉树脑、D 柠檬烯、trans 香叶基丙酮、苯甲酸甲酯、苯乙酮、苯并噻唑等物质在 72h达到最大 ,而syn 丁醛肟、1 ,3 ,3 三甲基 2 甲烯二氢吲哚在咬食 1h后就达到峰值 .天牛咬食诱导出的复叶槭挥发物 (即在正常植株中未被检测到的物质 )种类随时间的变化逐渐增加 ,在 48h达到 1 7种 .

The insect species of different vegetation types for different latitudes in Qilian Mountain Nature Reserve were analysed by the method of route investigation combined field surveys with scan, field collection with lamp entrapping, and field collection with recordation in history. Results showed that there are 1190 species of herbivorous insects belonging to 12 orders 125 families as well as 303 species of natural enemy insects in Qilian Mountain Nature Reserve. The adscription of forest insects in the international and Chinese fauna geographic provinces was also analysed. Analysis on regional climates of different latitude, divergence of vegetation levels and insect species indicated that the horizontal geographic distribution of forest insects shows a regularity of more species in the southeast and less species in the northwest of Qilian Mountain Nature Reserve. The distribution of forest insects was obviously affected by modern factitious production and economic activities.

采取线路调查为主,踏查与详查、现场采集与灯诱、现场采集与历史记载相结合的方法,对祁连山保护区不同纬度地区植被类型中的昆虫分别进行采集调查,查明祁连山保护区内分布的植食性昆虫12目125科1190种,天敌昆虫303种。对森林昆虫在世界和中国动物地理区系中的归属做了初步分析。据对不同纬度地域的气候、植被的水平差异和昆虫种类的比较分析认为,祁连山保护区森林昆虫的水平地理分布概况表现为东南部种类较多,西北部种类较少,近现代人为生产和经济活动对昆虫的分布格局产生了明显的影响。

In order to study behavior of insect herbivory and its damage to leaves, we investigated herbivory patterns on the leaves of 11 evergreen plant species in subtropical evergreen broad-leaved forests of Tiantong National Forest Park, Zhejiang Province. The results were as follows: (1) A total of 16 herbivory patterns were found, and for each tree species, herbivory patterns ranged from 10 to 13. The frequency of each herbi-vory patterns varied from 0.5% to 28.7%. The frequency of Edge Defoliation (ED) was...

In order to study behavior of insect herbivory and its damage to leaves, we investigated herbivory patterns on the leaves of 11 evergreen plant species in subtropical evergreen broad-leaved forests of Tiantong National Forest Park, Zhejiang Province. The results were as follows: (1) A total of 16 herbivory patterns were found, and for each tree species, herbivory patterns ranged from 10 to 13. The frequency of each herbi-vory patterns varied from 0.5% to 28.7%. The frequency of Edge Defoliation (ED) was the highest (28.7%), while that of Gall and Bloth-shaped mine (BM) were the lowest (0.5%). (2) Three distribution patterns could be classified according to the number of dominant herbivory patterns in a tree species: mono-dominant dis-tribution (with only one dominant pattern), such as Edge Defoliation on Rhododendron ovatum and Loropetalum chinense leaves; bi-dominant (with two dominant patterns), such as Edge Defoliation and Top Defoliation on Schima superba leaves; and multi-dominant (with three or more dominant herbivory patterns), such as in the other eight tree species. (3) Shannon-Wiener diversity index of herbivory patterns varied from 1.57 to 2.23 among 11 tree species, with the highest in Castanopsis sclerophylla and the lowest in Rhodo-dendron ovatum. Shannon-Wiener diversity index was higher in the six arbor species (2.040) than in five shrub species (1.882), and higher in dominant species than in companion species, however, the differenceswere not significant. (4) Correlation analysis showed that there were significant positive correlations among eight pairs of herbivory patterns and significant negative correlation among four pairs, suggesting similarities and differences in selection by herbivorous insects.

为探讨昆虫对植物叶片的取食行为和伤害方式,作者选择浙江天童常绿阔叶林内的11种常绿乔灌木为对象,对叶片虫食状类型和格局进行分析。结果如下:(1)共发现16种虫食状类型,每种植物叶片虫食状类型数在10–13种之间,每种虫食状出现频率在0.5–28.7%之间。缘食状出现频率最高(28.7%),虫瘿和泡状出现频率最低(0.5%)。(2)叶片虫食状分布格局可分为3种类型,即一种虫食状占绝对优势的单优格局,如马银花(Rhododendronovatum)和檵木(Loropetalumchinense);两种虫食状(缘食状和顶食状)共占优势的双优格局,仅有木荷(Schimasu-perba);3种及3种以上虫食状占优势的多优格局(其余8种植物)。(3)叶片虫食状多样性指数变化在1.57–2.23之间,最高为苦槠(Castanopsissclerophylla),最低为马银花;乔木的多样性指数(2.040)高于灌木(1.882),优势种多样性指数高于伴生种,但差异均不显著;多样性指数反映了虫食状类型和出现频率的综合差异。(4)16种虫食状类型中有8对显著正相关,4对显著负相关,可能反映出不同类型昆虫取食植物的趋同和差异。
