甘肃省兴隆山国家级自然保护区蝶类区系组成与多样性

为明确兴隆山自然保护区目前的蝶类组成及多样性状况,选取保护区全部5个林场(麻家寺、官滩沟、兴隆山、马坡和上庄)的8个代表性样线:麻家寺(Ⅰ)、官滩沟(Ⅱ)、兴隆山(Ⅲ)、银山(Ⅳ)、红庄子沟-骆驼岘-马滩(Ⅴ)、秦家湾-徐家峡-分豁岔(Ⅵ)、窑沟-双垄沟(Ⅶ)和马啣山(Ⅷ),进行蝶类调查,共采集蝴蝶标本1 271号,经鉴定隶属7科42属65种。蛱蝶科的种类数(21种)最多,眼蝶科的个体数(729只)最多,是保护区的优势类群,绢蝶科(39只)和凤蝶科(3只)都只有1种,是保护区的稀有物种。初步计算并分析了各样线的蝶类多样性指数、物种丰富度、优势度指数、均匀度指数和生境间相似性系数,结果表明:不同样线其蝴蝶的多样性不同,其中样线Ⅳ多样性指数最高,优势度指数最低;样线Ⅱ的多样性指数和物种丰富度均为最低,优势度指数最高。样线Ⅰ均匀度指数最低,优势度指数仅小于Ⅳ。样线Ⅷ的科数、属数、种数和个数都是最少,均匀度指数则最高。说明生境条件的变化对蝴蝶的多样性产生了影响,因此建议保护植被和环境以保证蝶类乃至其它生物的多样性。区系组成古北种占总数的46.154%,东洋种占3.077%,广布种占总数的50.769%。即保护区的蝴蝶以广布种为主,古北种明显多于东洋种。     

陕西化龙山国家级自然保护区鳞翅目昆虫多样性与垂直分布研究

对2017-2019年化龙山国家级自然保护区的鳞翅目昆虫资源进行了详细调查,并分析不同海拔对鳞翅目昆虫物种丰富度的影响。结果表明,化龙山有鳞翅目昆虫35科232属341种,其中尺蛾科、夜蛾科和蛱蝶科种类最为丰富。此外,鳞翅目昆虫在化龙山的物种丰富度随海拔变化呈现“驼峰型”模式,即在中海拔（1 500 m）的物种数量、标本数量、辛普森指数（D）以及香农-维纳指数（H′）都达为最大值,分别为189、2114、0.875和2.175,而在低海拔（1 000 m）和高海拔（2 000 m和2 500 m）区域的物种丰富度则较低,分析认为这可能是植被分布、温度条件以及人为活动等因素造成。     

应用斯氏线虫防治8种鳞翅目、鞘翅目昆虫的研究

1991—1993年在哈尔滨、牡丹江和阿城等地进行了应用斯氏线虫防治8种害虫的研究,其中鳞翅目5种:粘虫、甘蓝夜蛾、银纹夜蛾、向日葵螟、小菜蛾;鞘翅目3种:白星金龟子、马铃薯瓢虫和细胸金针虫。用3个种5个品系线虫测定的结果表明,除金针虫外,斯氏线虫对其它7种害虫均能侵染。室内试验表明,Beijing品系对粘虫、甘蓝夜蛾、向日葵螟和小菜蛾的致病力最强,害虫死亡率范围为79.3％—100.0％。田间试验表明,Beijing品系线虫对马铃薯二十八星瓢虫具有较好的防治效果。而NC32和Beijing品系在室内和田间对细胸金针虫均未表现出致病力。这些结果表明,斯氏线虫在本省具有广阔的应用前景。     

Long-term realised and projected growth impacts caused by autumn gum moth defoliation of 2-year-old Eucalyptus nitens plantation trees in Tasmania,Australia

Insect damage to production forests has the potential to reduce financial returns by retarding tree growth and causing mortality, however, long-term realised quantification of these losses is rare. In order to help elucidate economic damage thresholds for making spray decisions we capitalised on a natural outbreak of autumn gum moth, Mnesampela privata, in a 2-year-old Eucalyptus nitens plantation. Following the partial chemical control of this insect outbreak we measured the tree growth variables diameter at breast height over bark and height of five differing tree defoliation classes for 75 months following tree damage. At the end of this period a threshold model was fitted to describe the relationship between tree defoliation and realised tree wood volumes. The model revealed that realised stand wood volume was not significantly affected up until defoliation exceeded 60% and then declined sharply after this defoliation level was reached. Further support for this defoliation threshold was evident from multiple comparisons among defoliation classes that showed 50% defoliated trees did not have significantly different wood volume compared to more lightly defoliated trees, but did have significantly greater wood volume compared to trees that were 72% or more defoliated. To determine if the realised differences in wood volume resulted in differences in yield over a plantation rotation the E. nitens growth model NITGRO was used to on-grow trees to age 15 years for a ‘best case’ (type 1 growth response, constant growth rates from last inventory until harvest) and ‘worst case’ (type 2 growth response, divergent growth rates from last inventory until harvest) scenario. The threshold model was then fitted to the outcomes of both scenarios and the economic consequences of defoliation were clearly dependent on the growth function assumed.
