| 摘 要： | 本文通过收集苹果和梨树上的蛀果模拟自然落果,研究了苹果蠹蛾Cydia pomonella(L.)脱果幼虫的爬行特性。结果发现,58.91%的幼虫钻出蛀果进行了爬行,而41.09%滞留于果堆内部;在进行爬行的幼虫中,50%的幼虫爬行距离在0～1m之间,95%的幼虫爬行距离在0～7m之间,这意味着在实际防治过程中,落果周围0到7m的范围都需要做防治处理,而0～1m的范围需要重点防治;幼虫在果堆放置后的0～25d持续脱果,表明当果园内有落果时需要马上及时清理;幼虫结茧的高度大部分在50cm以下,在实际防治过程中,树干缚带诱杀幼虫时应将诱集带设置在距地面0～0.5m的主干上,以保证落果幼虫也可以被诱集带捕获。 |

| Abstract: | The crawling distance of codling moth Cydia pomonella （L.） larvae was investigated in larvae obtained from 1 128 damaged apple fruit samples. 58.91% of larvae crawled while 41.09% of them did not. The crawling distance of most larvae （95%） ranged from 0 to 7 m but the crawling distance of 50% larvae ranged from 0 to 1 m. These results indicate that control measures should be implemented within 0-7 m from where fruit have fallen and especially within 0-1 m from fallen fruit. The larvae continue to damage apples for 25 days after the fruit has fallen which means that fallen fruit needs to be collected in a timely fashion. Cocooning height tended to be below 50 cm which means that trap bands should be located within 0-50 cm of the ground. |
