| 摘 要： | 本文在连续３ａ研究的基础上，报道了湖北局部梨园新近发生的花器害虫──梨花蕾蛆（ｄａｓｉｎｅｕｒａｓｐ．）的年生活史及发生规律，提出了防治梨花蕾蛆的关键时期、用药方式及适宜的农药品种。另外，根据梨树生理及梨花蕾蛆的危害特点，运用辩证唯物论，讨论了梨花蕾蛆在梨园生态系统中的地位和作用，认为在一定条件下，梨花蕾蛆可以作为自然疏花的益虫来利用。

| Abstract: | The Pear Blossom Midge had damaged Pyrus communis in Spain and P. bretschneideri in SandongProvince, P. R. China. Since 1987, the pest insect has presented in Wusan Farm, caused P. pyrifolia a great lossaround 300 hm2, some orchards no fruits also. Based on 3 years study, the paper report its life history, damage-loss characters and occur rules in Hubei Province, and suggest the key peried, insecticide-use way and the fit in-secticides in controlling the pest as well. On the way, this paper discuss the status and use of the insect in pear or-chard ecological system, and claim that the insect as a nature blossom thinning tool would be much more valuable. |
