| 中文摘要 | 集約式農業對於生物多樣性與生態系服務是主要威脅之一。永續農法可能可以減輕此衝擊，但是如台灣簡化的地景，破碎的自然棲地下，水稻田是否有能有此效果仍具有不確定性。在2016年病蟲害控制研究中，我們在台灣北部宜蘭檢驗慣行與有機農法對於水稻田昆蟲群聚之影響，發現有機農法並不會增加四種類型昆蟲(總數、掠食者/寄生者、害蟲與其他昆蟲)的種類與豐度，而且慣行與有機農法之昆蟲組成並無不同，掠食者/寄生者的種類與豐度也都類似。慣行農法的害蟲豐度可能被某些未量測之掠食者所控制，以至於與未施殺蟲劑之有機農田有類似的量。此研究顯示不同農法再簡化的地景下，並不會影響水稻田病蟲害控制中的昆蟲多樣性。 |
| 英文摘要 | Agricultural intensification is one of the major threats to global biodiversity and ecosystem services. Sustainable management of agricultural lands can reduce these impacts, but few efforts have been made in the context of paddy rice fields, especially in simplified landscapes composed of large monocultures separated by fragments of natural lands, such as in Taiwan or elsewhere in Asia. In this study, during a pest control intervention, we examined the effects of management practices on insect communities under conventional and organic farming systems in the paddy fields of northern Taiwan in 2016. Our results showed that organic practices did not increase the species richness or abundance of the four insect groups (total, predators/parasitoids, pests, and other insects). In addition, the composition of the insect communities did not differ between organic and conventional farming systems. Both the abundance and richness of predator/parasitoid insects were similar between conventional and organic farming systems. The pest abundance in the conventional systems could be suppressed by other unmeasured predators and integrated management practices, which showed similar levels to the organic systems without pesticides. The results of this study suggest that farming systems may not influence insect biodiversity in simplified landscapes during the pest-control intervention. |
