苹果蠹蛾是新疆最严重的仁果类果树蛀果害虫。危害轻者,降低果实品质,危害重者,果品不勘食用。它不仅危害苹果,而且也危害沙果、海棠果、梨。由于该虫的危害,苹果产量可降低60％—70％,经济收入可损失30％左右。长期使用化学农药防治该虫,不但费用大,污染环境,杀伤天敌,而且使害虫产生了抗性。如农一师七团1984年打药10次,虫果率仍达58％。 近年来,国内外应用昆虫性信息素观察昆虫的物候学特性,调查虫口密度,诱杀雄蛾的研究报道较多。中国科学院新疆化学所制出的苹果蠹蛾性信息素经1985年—1986年
Cydia pomonella is the most serious pome fruit pests in Xinjiang. Harm the light, reduce fruit quality, endanger serious, fruit is not food for inspection. It not only endangers apples, but also endangers sand fruits, crabapples and pears. Due to the harm of the insects, apple production can be reduced by 60% -70%, economic losses can be lost about 30%. Long-term use of chemical pesticides to control the insects, not only costly, polluting the environment, killing natural enemies, but also to produce resistance to pests. Such as a division of seven farmers a group of 10 times in 1984, fruit rate is still up to 58%. In recent years, the application of insect sex pheromone at home and abroad to observe the phenology characteristics of insects, insect population density survey, more male males were reported. Chinese Academy of Sciences, Xinjiang Chemical made of codling moth sex pheromone from 1985 to 1986
