陕西省子午岭国家自然保护区鞘翅目不同采集方法比较研究

单一的采集方式,不能反应一个地区的鞘翅目(甲虫)多样性,不同采集时间和方式都对其有影响。本文使用马氏网、飞行阻隔器和扫网法在6-8月对陕西省子午岭国家级自然保护区石灰沟样地鞘翅目昆虫进行采集。结果共采得甲虫15 659头,其中马氏网采集到20科1 323头,飞行阻隔器采集到30科10 330头,扫网法采集到24科4 006头。经分析得出以下结论：1、鞘翅目昆虫数量：飞行阻隔器>扫网法>马氏网。2、优势科的数量：马氏网>飞行阻隔器=扫网法。3、采集科级数量：飞行阻隔器>扫网法>马氏网。     

A successful Case of Pheromone Mass Trapping of the Bark Beetle Ips duplicatus in a Forest Island, Analysed by 20-year Time-Series Data

The experimental testing of the hypothesis of population reduction by mass trapping with the establishment of treatment/control areas is a logistic problem on landscape scale. We suggest a possible test based on time-series analysis of tree-mortality data. Our example is helped by: an island effect, a 20-year tree-mortality record, and a very competitive synthetic aggregation pheromone. The successful development of synthetic pheromone (ipsdienol and E-myrcenol) dispensers, and the dose-response of wick-dispensers is briefly described. In the 2000 ha of spruce (Picea mongolica) forest reserve at Baiyinaobao, surrounded by grassland, 80 traps were employed for 3 years, catching 0.5–1.7 million beetles/year. In spite of intensive conventional management since 1982 (17 years), the long-term tree mortality had been oscillating around 600. During the first three years of mass trapping, tree mortality was down to 118, 100, and 88, respectively. Neither natural population cycles nor weather conditions could explain the 3-year mortality drop. Cycles did not drive the drop, as auto-correlation function (ACF) and partial ACF plots do not show any clear periodicity, only a weak 5-year cycle is visible. Weather did not explain the drop, as the 3 years of mass trapping had average rainfall and higher than average temperatures. Climate data show negative correlations of tree mortality and temperatures on year basis and a 20-year trend of increased monthly averages, especially for July temperature. The increased temperature (global warming) will increase stress on trees, but mass trapping may have counterbalanced this new threat to the forest.

Rove beetles (Coleoptera Staphylinidae) – Their abundance and competition with other predatory groups in Bt maize expressing Cry34Ab1, Cry35Ab1, Cry1F and CP4 EPSPS proteins

This study investigated the effects of different GM maize crops on the abundances of rove beetles. It also investigated competition between rove beetles and other epigeic arthropod predatory groups (ground beetles and spiders). Altogether a total of 5926 rove beetle individuals belonging to 25 species were collected. Whilst the average number of rove beetle individuals per replicate per sampling date varied and, moreover, decreased each year, there were no observed differences in rove beetle abundance when compared between isogenic and GM maize plots within the study period. Furthermore, no clear trends on positive correlations between weed coverage and rove beetle abundances were detected. Altogether a total number of 76,070 ground beetle individuals and 11,126 spiders (including all Araneae) were collected with pitfall traps. Analyses revealed a strong negative relationship between rove beetles and the other two groups in each treatment and year. According to the results the effect of interspecific competition on rove beetle abundance in GM maize is much higher than the effects of treatments including both Bt toxins and extra glyphosate applications.     

中山五桂山生态保护区鞘翅目昆虫名录

2007年7月~2011年5月,对广东中山市五桂山生态保护区的昆虫多样性进行专项调查。采用线路调查和标准调查相结合的方法采集昆虫,及时制成针插标本。一些常见昆虫种类对照专业昆虫图鉴进行鉴定;限于当时条件无法鉴定的,则送国内昆虫分类专家鉴定。共制成昆虫标本4万号,鞘翅目昆虫计33科258种。
