黄板诱杀技术在防治葡萄斑叶蝉成虫中的应用研究

采用粘虫板对葡萄园内的葡萄斑叶蝉成虫黄板诱杀技术进行了研究,并对不同黄板的诱杀效果做了比较。结果表明:冀林黄板每天每板平均诱虫量为48.5头,效果明显优于其他两种黄板,市售黄板和自制黄板。北向黄板诱虫量与南向诱虫量有显著性差异。黄板悬挂高度10 cm为宜。密度30~40块/667 m2,即可达到控制葡萄斑叶蝉危害的目的。     

苦楝斑叶蝉的初步观察

苦楝斑叶蝉(Erythroneura Sp)属叶蝉科(Cicadelljdae)小叶蝉亚科(Typhlocy bjnae)斑叶蝉属。苦楝斑叶蝉严重危害苦楝,吸食苦楝叶汁,使叶面灰黄,降低光合作用并提早凋落,直接影响苦楝的生长。我省各地都有苦楝斑叶蝉为害。据报导,浙江、广东等地也有发生,还传播苦楝丛枝病和苦楝簇     

FORESTAR：A decision—support system for multi—objective forest management in Northeast China

Past monoculture forestry in China has contributed to countrywide ecological disasters and economic difficulties in forestry regions. China‘s new forestry programs, Natural Forest Conservation Program and Returning Farmlands to Forests Program, provide opportunities for ecosystem management of mountain forests in China. A decision support system, FORE-STAR, has been developed for better managing and protecting natural forests in Changbai Mountain area. It uses GIS-based forest inventory data at a scale of forestry bureau. The first version contains two sub-modules: forest operation and forest res-toration. Under each sub-module, users can compare several decision options and make optimal choices. It can help field for-esters, forest managers, and policy makers make multi-objective and consistent decisions in planning forest management at hierarchical administrative scales.     

Research trends: Policy impact evaluation: Future contributions from economics

Economic research has become more empirical, and much of the shift has been due to the broad applications of impact evaluation (or IE) methods for measuring the potential effects of policies or programs on outcomes of interest. The objective of this article is to introduce the essential IE methodology and literature to the audience of this journal and discuss how we can take advantage of these research developments to improve the quality of our own work and subsequent publications. Following an overview of the core IE concepts and methods, we will give an overview of the recent uses of these methods to address forest policy issues and outline the basic steps of sampling and data generation involved in an IE study.
