Abstract
The seasonal outbreak of the rice borers, leafhoppers and planthoppers is generally associated with climatic weather and environmental conditions. According to the ecological environment of these pests in Vietnam, the relative outbreak and their damage made to rice plants is concerned with the basic environmental conditions which are more important than weather throughout the year, wheras their infestation of rice plants in central Vietnam is more serious than in Southern Vietnam. Especially the outbreak of the leafhoppers, Nephotettix spp., and planthoppers, Nilaparvata lugens and Sogatella furcifera is more abundant than that of the rice borers, namely, Tryporyza incertulas, Chilo suppressalis, and Sesamia inferens. The new varieties of IR-5 and IR-8 are more susce ptible to these pests than local varieties. The damage of rice plants in irrigated fields is more serious than that in ordinary fieldss where the water level is usually high.
越南水稻螟蟲，稻葉蟬類及稻飛蝨類等之發生對於季節氣候與環境均有相互密切之關係，按其在越南發生環境，據筆者研究結果，其蔓延猖獗之趨勢，認爲環境因子較氣候因子尤爲重要。因此，中越水稻區以適宜蔓延滋生，而構成嚴重之災害時有所聞。但湄公河三角洲水稻區之環境，鮮有聞其爲害成災者。在稻作害蟲中以黑尾葉蟬(Nephotettix spp.)及褐飛蝨(Nilaparvate lugens)及白背飛蝨(Sogatella furcifera)爲害較螟蟲熾烈。螟蟲包括：一點螟蛾(Tryporyza incertntas)條化螟Chilo suppressallis)紫螟(Sesamia inferens)等。稻飛蝨類之爲害水稻品種間，亦有顯著差異，其中以IR-8及IR-5等品種遭其爲害較當地品種慘重。
