在实验室中,调查了松毛虫赤眼蜂雄蜂寄主栖息地定向行为与一些因子的关系.嗅觉试验表明,马尾松毛虫雌蛾翅膀的气味对雄蜂寄主栖息地定向行为无直接关系.来自寄主植物马尾松针(186mg)的气味能刺激雄蜂加强在气味区的搜索活动,但仅有松针气味尚不能明显地将雄蜂滞留在气味区内。同种雌蜂(N=20头)的气味对雄蜂虽有明显的引诱作用,但对雄蜂的滞留亦无明显的影响,当松针(186mg)加上雌蜂(N=20头)时,气味区滞留的雄蜂头数即明显增加,由此可见,奇主植物和雌蜂气味的共同作用是雄蜂寄主栖息地定向中的关键因子。
In the laboratory, we investigated the relationship between directional behavior and some factors in the host habitat of Trichogramma dendrolimi, an olfactory test, which showed that the odor of the female moth’s wing had no direct effect on the directional behavior of the drone’s host habitat.From the host plant The odor of Masson pine needles (186 mg) stimulated drones to intensify search activity in the odor zone, but only the pine needles were not yet able to clearly trap drones in the odor zone. The odor of the same species of female bees (N = 20) showed no obvious effect on the drones although there was obvious attraction to the drones. When the pine needles (186 mg) and female bees (N = 20) In the area, the number of male bees stranded in the area increased significantly. Thus it can be seen that the synergistic effect between the odorous plants and the female bees is the key factor in the orientation of the host honeybee habitat.
