吸果夜蛾是柑桔的主要害虫之一,前期为害造成落果,后期为害造成落果和贮运期果实的腐烂,早熟品种受害尤甚。据报道,我省山地柑桔果实受害落果严重的达50％左右,一般的也在10％以上。吸果夜蛾种类多,发生规律、取食为害及生活习性各异,幼虫分散在果园内外杂草上,成虫飞翔力强,活动范围广。在防治上,目前多采用果实套纸袋;发展迟熟品种;在果园附近铲除术防已、汉防已等中间寄主;在害虫盛发期采取夜晚人工捕杀;用香茅油或设置黄色荧光灯对害虫进行拒避;等等。这些防治方法花工大、成本高,效果不很理想。迄今尚未有理想而经济的防治吸果夜蛾的报道。1984年开始,大坂村桔园为增加短期效益,进行桔园内外种植香蕉试验,发现香蕉花对吸果夜蛾具有极显著的诱引效果,为此,笔者进行了本试验观察,现把结果初步整理如下: Fruit-bearing insects are one of the major pests of citrus. Early damage caused fruit decay, later decay caused fruit decay and fruit storage and decay, especially for early-maturing varieties. It is reported that mountainous citrus fruit damage in our province dropped seriously about 50%, generally 10% or more. Many species of louse, law of occurrence, feeding damage and different habits, larvae scattered in the orchard weeds, adults fly strong, wide range of activities. In the prevention and control, the current use of fruit sets of paper bags; the development of late-maturing varieties; in the orchard near the eradicate the anti-Fang Han, anti-Han has been waiting for the middle of the host; pests in the night to take artificial hunting at night; with citronella oil or set the yellow fluorescent pair Insect repellent; and so on. These control methods flower large, high cost, the effect is not very satisfactory. So far there is no ideal and economical report of the control of the fruit worm. Since 1984, Osaka Village orange garden in order to increase short-term benefits, orange plantation banana cultivation both inside and outside and found banana flower on the absorption of the Spodoptera maximum highly attractive effect, therefore, I conducted the test observation, the results Preliminary finishing as follows:
