In a series of indoor experiments with electric artificial flowers, I found that bees establish traplines based on spatial memory, and that traplining allows bees to compete more effectively. I also demonstrated with theoretical models that traplining increases mating distance and mate diversity, and decreases a novel type of self-pollination, coined "iterogamy." Finally, I developed the microsatellite DNA markers in Salvia nipponica.

在一系列电动人造花的室内实验中，我发现蜜蜂根据空间记忆建立陷阱线，而陷阱线可以让蜜蜂更有效地竞争。我还用理论模型证明，诱捕增加了交配距离和配偶多样性，减少了一种新的自花授粉，即“异花受精”。“最后，我开发了日本鼠尾草的微卫星DNA标记。
