近几年来,在河北、山东等省梨产区,蝽象危害日益严重,仅河北危害面积已达30多万亩,一般果园蝽象果率达10%以上,蝽象果大部分成“疙瘩梨”,失去了经济价值,损失严重。通过研究表明,化学防治虽然能有效控制蝽象的危害,但蝽象生育期长,食性杂,又善于飞翔,单纯的药剂防治经济效益并不十分理想。为更好地控制其危害,根据研究结果,我们提出综合防治技术是最佳途径。 In recent years, in the pear-producing areas of Hebei and Shandong provinces, the stink bug has become more and more serious. Only the hazardous area in Hebei has reached more than 300,000 mu. The fruit rate of stinkbugs in the orchard is over 10%. Most of the stink bugs are “knots Pear ”, lost its economic value, suffered serious losses. The research shows that although chemical control can effectively control the damage of stink bug, stink bug has long growth period, miscellaneous food, and is good at flying. The economic benefits of simple chemical control are not very satisfactory. In order to better control its harm, according to the results of the study, we propose a comprehensive prevention and control technology is the best way.
