膜翅目昆虫miRNA基因家族的鉴定和进化分析

寄生蜂是重要的天敌昆虫,一直以来是生物防治的研究热点。对寄生蜂miRNA的研究可以进一步揭示其生物学特性。本研究选取包括6种寄生蜂在内的19种膜翅目昆虫,鉴定了这些昆虫的miRNA基因及家族,并分析膜翅目昆虫的保守miRNA家族的进化。发现12个miRNA家族为膜翅目昆虫特有,表明在膜翅目昆虫的进化早期发生了miRNA家族的大规模获得事件。分析发现在寄生蜂不同谱系尾蜂、小蜂总科及茧蜂科中,保守的miRNA家族存在多次独立丢失现象。本研究为进一步挖掘寄生蜂中的miRNA-基因靶标关系提供了数据基础。     

寄生性膜翅目昆虫和生物多样性

生物多样性（Biologicaldiversity）的指世界生物种类的多样性，包括遗传多样性和它们所形成的集合体（生境、群落和生态系等）的多样性，即多样化的生命实体群的特征。这是自然界生物学的财富，是人类生活的健康的保证，生物多样性也广泛的反应了基因、种和生态系的相互关系。l寄生性膜翅目昆虫在生物多样性中的地位1．1寄生性膜翅目昆虫的数量据统计昆虫的种数要超过世界上已描述的生物种数的1／2以上，这些种类在陆地生态系中比其他任何动物类群对自然界能产生更大的影响，而寄生性膜翅目昆虫是昆虫中较大的类群之一。据最近统计已描述…

三江平原典型湿地不同林型昆虫物种多样性研究

利用扫网,黄盘和巴氏罐诱法对三江平原典型环形湿地周围三个不同类型树林(岛状林,杨树林,松树林)的昆虫进行采集,经初步整理和鉴定,共采集标本24212号,其中昆虫20948号,分属于14目。其他的属于蛛形纲和多足纲。昆虫中种类最多的是双翅目和膜翅目,其次是弹尾目,同翅目,鞘翅目和缨翅目。在高的分类阶元(目)Shannon-wiener指数在松树林最高,杨树林最低。昆虫数量在各个林型中没有明显的不同。在这三个林型里面发现了长翅目蝎蛉,丰富了我国对于蝎蛉分布北限的记录,表明三江平原湿地区是我们昆虫多样性保护的一个重要区域。     

Occurrence of insects in coniferous roundwood imported to Sweden from France and Chile

Sweden requires all coniferous roundwood from countries outside Europe to have been debarked but makes no requirement for European wood. Six shipments of unbarked roundwood of Pinus pinaster from France and 14 shipments of debarked P. radiata logs from Chile were inspected in Sweden during 1988 and 1989. The imported wood from France yielded 92 insect species (90 Coleoptera and 2 Hymenoptera). Seventeen of these species do not occur in Sweden. All six consignments were thoroughly attacked by bark- and wood-boring insects, representing 25 species. The logs from Chile had been well debarked; less than 1% of the inspected logs contained living insects. Nevertheless, a total of 49 insect species (46 Coleoptera, 1 Isoptera, 1 Hymenoptera and 1 Orthoptera) were found in the 14 shipments. Of these species 21 are not indigenous to Sweden.     

Two new species of egg parasitoids (hymenoptera: Encyrtidae) of wood-boring beetle pests from China

Oobius agrili sp.n. andAvetianella xystrocerae sp.n. (Hymenoptera: Encyrtidae) are described from China. Morphological characters of the new species are illustrated.O. agrili is an egg parasitoid of the emerald ash borerAgrilus planipennis Fairmaire (Coleoptera: Buprestidae) andA. xystrocerae is an egg parasitoid of the wood borerXystrocera globosa (Olivier) (Coleoptera: Cerambycidae). The two new species are potential biocontrol agents of economically important pest insects. The type specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences, Beijing (IZCAS). http://www.phytoparasitica.org posting May 17, 2005.     

Diversity and Selectivity of Flower-visiting Insects in Xipu Forest Park

[Objective]This study was conducted to understand the species and quantity of flowervisiting insects in Xipu Forest Park,supplement the data of local flowervisiting insects,and fill the research gap of flowervisiting insects in the Lesser Hinggan Mountain.[Method]The methods of route survey and sample plot survey were used to investigate the community of flowervisiting insects,and the method of net catching was used to collect flowervisiting insects and record relevant data.[Results]A total of 1526 flowervisiting insects belonging to 79 species,27 families and 9 orders were found.Among them,Lepidoptera was the most,accounting for 40.51%,while Odonata,Mantodea,Hemiptera and Thysanoptera are the least.The results showed that the insect diversity index and insect dominance index were higher in the flower cultivation area,the insect evenness index was highest in the lawn area,and the flowervisiting insects in arbor area and flower shrub area were more similar.Rosaceae had the most flowervisiting insects,followed by Compositae,Cruciferae and Leguminosae.[Significance]The study provides scientific basis and data support for the rational development and utilization,biodiversity protection and sustainable development of forest parks.     

The use of dyes to mark populations of beneficial insects in the field

Dyes and dusts have been used to mark insects internally and externally for decades, the majority of examples coming from laboratory-reared pest species used in mark-release-recapture studies. Using dyes or dusts to mark populations of pests and beneficial insects simultaneously in the field has received less attention. We evaluated a water-soluble fluorescent dye and a resin-based fluorescent pigment sprayed on crops to mark beneficial and pest insects, and monitored the dispersal of marked insects. Our results show that resin-based dyes provide an effective mark on several species of insects among several orders. The resin-based dye is also relatively inexpensive, non-toxic, UV-stable and water resistant, unlike a water-soluble dye. Using the resin-based dye in a broccoli production system, we were able to monitor simultaneously the movement of field populations of the parasitoids, Diadegma semiclausum (Hellén) (Hymenoptera: Ichneumonidae), and Apanteles ippeus (Nixon) (Hymenoptera: Braconidae) and the adult stage of the host, diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae). Resin-based dye applied on a crop is an effective way to mark and monitor the dispersal of populations of beneficial and pest insects in relation to agricultural practices, integrated pest management and conservation biological control.     

Insect pollinators of the invasive plant, Rosa multiflora (Rosaceae), in Iowa, USA

Invasive species often require mutualistic relationships to successfully invade new environments. Insect pollination is an example of a mutualism that is required for seed-set in the invasive species, Rosa multiflora Thunb. (Rosaceae), an obligate outcrosser. To determine the insect pollinators visiting R. multiflora flowers in Iowa, USA, we collected insects on yellow sticky traps placed on plants during the period of blooming and visually observed insects visiting the flowers. The common insect orders that were collected on the sticky traps included Coleoptera, Diptera, Hemiptera, Hymenoptera, Mecoptera, and Thysanoptera. Many of the insects found on the sticky cards were known to feed on pollen. However, we did not collect Apidae (bumble bees and honey bees) on the sticky cards. We observed Bombus spp. and Apis mellifera foraging on the flowers. Syrphid flies were the most commonly observed taxa visiting the flowers. Our results indicate that R. multiflora is utilizing common generalist insect pollinators in Iowa and that pollination is not a limiting factor for this invasive species.
