| 中文摘要: |
| 为评价黄色粘虫板在梨园蚜虫测报中的应用效果，分别在大棚和露地栽培的梨园内悬挂黄板，并统计田间新梢蚜虫为害率及黄板上诱集蚜虫的数量。调查发现平均每张黄板上蚜虫诱集量与黄板悬挂期间的平均温度及最高、最低湿度呈显著的负相关。田间新梢蚜虫发生率与黄板上蚜虫诱集量有显著的线性关系，但是黄板诱集蚜虫个别值的预测值不可信，可以利用平均值的预测区间结合田间无翅蚜发生高峰来预测田间蚜虫的发生情况。另外，黄板上诱集到的蚜虫天敌与蚜虫的数量关系密切。 |
| 英文摘要: |
| Yellow sticky card traps were used as a tool for estimating absolute densities of aphids (Aphididae) in pear orchard. Two-week trapping was conducted in tunnel and open field with traps deployed directly in trees, one trap per tree. Aphids incidence in current shoots and aphids number captured by yellow sticky traps were calculated. It was found that air temperature, maximum and minimum daily humidity were negatively correlated with numbers of aphids trapped in tunnel. A significant linear relationship was found between trap captures of aphids and aphid incidence in current shoots. However, little confidence could be placed on individual predictions of aphid densities on leaves based on numbers of aphids on traps. Thus, predictions of aphids on traps combining with apterous aphids peak in fields were suggested to estimate aphid occurence. In addition, the quantities of natural enemies for aphids were correlated with aphids trapped in tunnel. |
