水稻害蟲之綜合防治

Abstract

台灣水稻害蟲主要者有10餘種，在一期作平均可造成15.4%，二期作29.9%之稻穀損失。對該等害蟲之防治，以往偏重於殺蟲藥劑之使用，導致諸多副作用。有鑑於此，近年來積極發展綜合防治方法，研究內容包括各種主要害蟲經濟為害基準防治及防治適期之釐定，耕作防治法對害蟲族群之影響，害蟲天敵之保護，抗蟲品種之培育與利用，藥劑使用時期與方法以及害蟲之發生偵查與預測等，並已累積相當成果。 In Taiwan, one hundred and forty species of insect pest had been recorded on rice, among them, about 10 were considered economic importance to rice production. These pests caused about 15 and 30% yield losses in the first and second rice crop, respectively. Chemical application was wildly and heavy used for preventing such losses during the period from 1950 to 1970, that resulting a considerable side effects to the pests and environment.
