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
The first three flights of bumblebees were observed after corn, sweet potato and peanut seedlings were released respectively. The results show that the first flight is an escape type, distributed randomly in the observation area, while the other second flight has a clear selectivity to the landing point. In the corn-peanut farming area, 81.82% of bumble bees’ second flight target is corn adjacent to peanuts, but the stay time is very short, with an average of only about 3 minutes. In the sweet potato legume and peanut temporary cropping area is not the phenomenon, sweet potato and peanut fields in the morning on the ratio of 51.43% and 48.57%, the afternoon of 33.53% and 76.47% on the peanut fields Clearly selective. The goal of the third flight is clear, and most bumble bees choose to land in the peanut zone. The interval between each flight is shorter than afternoon, indicating that the bumble bee is active in the morning
