1 The Uplands Program Thai-Vietnamese-German Collaborative Research Programm Subproject C1.2

2 The Uplands Program C1.2 Project title Analysis and manipulation of the agrobiocoenosis for sustainable management of litchi growing systems at hillsides of northern Thailand

3 The Uplands Program C1.2 Linkage C1.2 agro- biocoenosis B1.2, B3.1 irrigation fertigation D1.2 fruit production B2.2 agrochemical transport Sustainable management of litchi growing systems

4 The Uplands Program C1.2 Problem statement High inputs of insecticides and herbicides cause major problems in litchi orchards

5 The Uplands Program C1.2 Overall goals (C1) Explicit goals (C1.2) Reduction of pesticide application Increase in biodiversity in plants and arthropods Ecology of the major pest species Role of attendant vegetation for beneficial arthropods

6 The Uplands Program C1.2 Major results from phase 1  37 pest species identified  6 species of high significance for production and yield  3 species can not be controlled by insecticide application.  Regular mowing leads to an increase in diversity of flowering plants (92 species in total) Researcher: P. Schütz
