| 摘 要： | 对土蜂在玉米、甘薯 豆类分别与花生临作田被释放后最初的 3次飞行行为进行了观察。结果表明 ,第一次飞行是一种逃逸式的 ,在观测区内呈随机分布 ,其它二次飞行则对着陆点有明确的选择性。在玉米花生临作区 ,81.82 %土蜂的第二次飞行目标是与花生相邻的玉米 ,但停留的时间很短 ,平均只有 3min左右。在甘薯 豆类与花生临作区则没有这种现象 ,当日上午在甘薯 豆类田与花生田的比例为 51.43 %和 48.57% ,当日下午为 3 3 .53 %和 76.47% ,对花生田有明显的选择性。第三次飞行的目标非常明显 ,大多数土蜂都选择在花生区降落。每次飞行的间隔时间上午比下午短 ,表明上午土蜂比较活跃 |

| Abstract: | A study was conducted in corn-peanut, sweet potato -b ean-peanut fields on the flying behavior of the white grub parasitoid Tiphia poilliavora Rohwer wasps. Observation on the first three times of flying, afte r the wasps being released, revealed that the first flying was a escape style an d not showed preference for any special crops in landing. 81.82% of wasps landed on corn leaves at the second flying but stayed for just about 3 minutes. In the sweet potato-bean-peanuting field, 51.43% of wasps landed on sweet potato in contrast with 48.57% landed on peanuts and in the afternoon 33.53% on sweet pota to compared with 76.4% landed in peanut field. The majority of wasps preferred l anding in peanut field on the third flying in both type fields of intercropping. The behavior of flying was different between mor-ning and afternoon. The durat ion of time between two flies showed that the wasps were more active in the morn ing than in the afternoon. |
