由于台湾气候温暖,雨量丰富,病虫危害一直是严重影响柑桔生产的主要因素。八十年代以来,通过人工放养大量的不孕果蝇,便其与野生果蝇性交而产生不能孵化的卵,从而有效地减轻了果蝇对柑桔果实的危害。柑桔立枯病在台湾省的桔园中的发生率很高,已成为椪柑、桶柑、柳橙、尤力卡柠檬和葡萄柚等柑桔商品化栽培品种的毁灭性病害。该病害由病毒引起,潜在感病后即会使树体生长势削羽,产量下降,同时阻碍果实生长发育,导致畸形果,产生劣质果品,严重时则会显著缩短树体经济栽培寿命。自从八十年代以来,台湾当局和有关科学家加强了柑桔立枯病的发病机理和防治对策研究,发现在椪柑和桶柑混植园中,
Due to Taiwan’s warm climate and abundant rainfall, pests and diseases have always been a major factor that seriously affects citrus production. Since the 1980s, by infecting large numbers of infertile fruit flies manually, they intercourse with wild fruit flies to produce eggs that can not be hatched, thus effectively reducing the harm of fruit flies to citrus fruits. The high prevalence of citrus curl blight in orange groves in Taiwan has become a devastating disease in commercial cultivars of citrus, such as citrus, barberry, orange, yelijia lemon and grapefruit. The disease is caused by the virus. After the potential infection, the growth of the tree will be cut, the yield will drop, the growth of the fruit will be hindered, the deformed fruit will be produced, the poor fruit will be produced, and the economic life of the tree will be shortened if it is serious. Since the 1980s, the Taiwan authorities and relevant scientists have strengthened the study on the pathogenesis and control strategies of citrus blight and found that in the mixed plantation of citrus and barley trees,
