中文摘要: |
在我国蓝莓是重要的浆果类作物, 而铃木氏果蝇对蓝莓的为害特征及为害程度尚无报道?本研究通过诱捕器监测蓝莓园中成虫的种群发生动态, 并采用随机取样法每周调查‘瑞卡’‘北陆’‘美登’和‘蓝金’4个蓝莓品种的果实受害率, 同时研究了受害果实内幼虫取食为害蓝莓的持续期?在连续13周的诱捕调查中, 共捕获到9 999头铃木氏果蝇, 其诱捕高峰期是8月22日, 首次诱捕到成虫是7月13日, 而通过采样首次调查到受害果是7月24日?表明诱捕器能够有效监测铃木氏果蝇的种群动态变化, 并提前11 d预警果实受害?各品种果实成熟初期受害率均很低?仅为0~2%, 然而随着果实成熟度增加受害率均明显增加, 其中‘美登’受害率最低为34%, 而其他3个品种的受害率均高于80%, ‘蓝金’最高, 达90%?25℃条件下, 铃木氏果蝇所产卵次日即发育为幼虫, 且持续8 d后仍为幼虫在果实内为害, 可见蓝莓果实一旦被害即使采摘也无法避免损失? |
英文摘要: |
Blueberry is an important economic fruit, however, there was no report on damaged symptom and damaged level of blueberry caused by Drosophila suzukii in China. We monitored adult occurrence by solution traps, and sampled blueberry fruits randomly each week on four cultivars (‘Reka’ early harvest, ‘Northland’ middle early harvest, ‘Blomidon’ middle harvest, and ‘Bluegold’ middle late harvest) to test the incidence of damaged fruit and the duration of larval damaged in blueberry fruits. Totally 9 999 D.suzukii adults were caught by traps during consecutive 13 weeks monitoring. The first adult was trapped on 13 July and then population reached to peak on 22 August, while the first damaged fruit was found on 24 July. These results indicated that solution traps were effective tools to monitor the D.suzukii, and function well to predict the fruit damage 11 days ahead. The incidences of damaged fruit were very low (0-2%) of all cultivars at initial ripening stage, and then dramatically increased with the fruit ripe. The incidence of damaged fruit of ‘Blomidon’ kept at low level (34%), while those of the other three cultivars were higher than 80%, especially ‘Bluegold’ researched to 90%. At 25℃, larvae continued feeding damage in blueberry at least eight days from the second day when eggs were laid, therefore, loss cannot be avoided once fruit was damaged even it was picked. |
