The results obtained were as follow : 1. The order of the insects collected in the shifting plots was richer than those in the improved plots and the semi-improved plots. The structure of insect community in the shifting plots at the order level was distinct from those in the other plots and had a tendency of gradual simulation of that in the natural forest. 2. The richness of insect family in the second year increased in comparison to that in the first year in all plots. The value of richness in the shifting plots was the highest of all plots. 3. The shifting plots, in comparison to the rest of the plots surveyed, was rich in the species, high in the index of species diversity and complex in the structure of insect community. These tendencies bacame conspicuous in the second year. 4. The insect fauna in the shifting plots in the first year was quite distinctive from those in the other plots and, in the second year, tended to simulate those of the other plots.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3958"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
