| 2007－2009年连续3年在浙江大学果园监测柑橘小实蝇发生动态,调查其危害程度。结果显示，套袋梨区与不套袋梨区的柑橘小实蝇虫口数量和危害程度相差甚大，诱虫量后者比前者多5.35倍。2007－2008年套袋梨区在梨果采收前诱虫量很少，仅占总诱虫量的0.25%，盛发期在9月下旬－10月上旬，梨果几乎不遭受柑橘小实蝇危害；而不套袋梨区在梨果采收前诱虫量占总诱虫量的6.06%，成虫盛发期在8月中旬－10月中下旬，覆盖着梨果的整个转色至成熟采收期，采收期梨果受害率高达78%~95%。由此表明，采取梨果套袋和及时捡拾落果并加以妥善处理，能显著减少柑橘小实蝇对梨果的危害程度，推迟和缩短成虫盛发期，是控制柑橘小实蝇的安全、环保的有效措施。 |
| 英文摘要: |
| Dynamics and damages of Bactrocera dorsalis in the orchards of Zhejiang University were investigated in 2007-2009. The results showed that there was obvious difference in population and damage of the pests between bagged and unbagged pear areas. The fly population was 5.35 folds more in unbagged areas than in bagged areas. In 2007-2008, the number of male flies caught in the bagged area before pear harvesting was very low, only accounting for 0.25% of the total number, and almost no pears were damaged, and the population peak occurred in late September—early October; while in the unbagged area it accounted for 6.60%, and the peak came in mid August—late October, covering all maturing stage of the pear, and 78%-95% of the pear were damaged by the pest. Therefore, bagging the pears and picking the fallen pears on the ground could significantly reduce the damages of the pests, postpone and shorten the peak stage of pest, and are safe and environment friendly practices for the control of the pest. |
