| 摘 要： | 本试验旨在探究两种生物防治方法对黑龙江哈尔滨地区梨树蛀果害虫的防控效果及监测梨树蛀果害虫的发生动态。针对不同的蛀果害虫采用相应的防控方法，并监测不同处理下害虫发生动态与数量。结果表明，调查期间梨小食心虫、苹果蠹蛾在黑龙江哈尔滨地区梨园内一年有3次发生高峰，桃小食心虫有2次发生高峰。梨小食心虫发生高峰分别在5月下旬、7月上旬、8月中旬；苹果蠹蛾发生高峰分别在6月上旬、7月上旬、8月上旬；桃小食心虫分别在7月下旬及8月下旬达到发生高峰。悬挂梨小食心虫、苹果蠹蛾性信息素迷向散发器可有效干扰害虫正常的交尾行为，全年范围内降低其发生数量。释放松毛虫赤眼蜂对梨小食心虫、桃小食心虫有较好防治效果，可降低其对果实造成危害的可能，但该方法对苹果蠹蛾的防治效果一般。因此根据害虫发生规律，充分利用不同的生物防治方法，可进一步提高对梨树蛀果害虫的防治效果。

| Abstract: | This study aimed to investigate the biological control of pear borer pests in Harbin,Heilongjiang,and to monitor the occurrence of them.The control targeting different pests varied and occurrence dynamics under different biological control methods were monitored.The results showed that there were three population peaks in Grapholita molesta and Cydia pomonella in the pear orchard in Harbin during the survey period,and there were two peaks in Carposina sasakii.The peaks of G.molesta were in late May,early July,and mid-August;of C.pomonella,in early June,early July,and early August;and of C.sasakii,in late July and late August.The G.molesta and C.pomonella sex pheromone diffuser effectively interfered with the normal mating behavior of the pests and reduced their occurrence throughout the year.Trichogramma dendrolimi showed good control on G.molesta and C.sasakii,reducing fruit damage rate,but low control on C.pomonella.Therefore,different biological control methods can be used to control pear tree borer pests according to their occurrence pattern. |
