我国自山区发展果树以来,吸果夜蛾的危害日益加剧。青岛崂山山区虽处温带(北纬36度多),但因在山东半岛南侧,黄海之滨,气温比较高,年平均温度约11.19℃,冬季最低温度很少低于零下15℃;湿度比较大,年平均降水量约822毫米,林木葱郁,野生植物繁茂,附近盛产水果(主要为苹果),很有利于吸果夜蛾的孳生与扩散,举凡苹果、梨、桃、杏、李、葡萄、樱桃、无花果等无不受其危害。特别是皮薄、汁多、香
Since the development of fruit trees in mountainous areas in our country, the harm of the fruit-bearing moths is getting worse day by day. Although the Laoshan mountainous area in Qingdao is temperate (latitude 36 degrees north latitude), its annual average temperature is about 11.19 ℃ due to the high temperature in the south of Shandong Peninsula and the coast of the Yellow Sea. The minimum temperature in winter is rarely less than minus 15 ℃. , The average annual rainfall of about 822 mm, lush forests, lush wild plants, near the rich fruit (mainly apples), is very conducive to the breeding and spread of fruit-bearing moths, such as apples, pears, peaches, apricots, plums, Cherries, figs and so on are all affected by its harm. Especially thin, juicy, fragrant
