trail pheromone

基本解釋

When an ant finds food, she takes it back to the nest, leaving behind a pheromone trail that will attract others.
當(dāng)一只螞蟻找到了食物，它把食物帶回巢穴，并且在路上留下信息素以吸引其他的螞蟻。
"When these ants bring food back to the nest, they lay a pheromone trail that tells other ants to go get more food, " Harper explains.
“當(dāng)這些螞蟻將食物帶到蟻巢時，它們會在途中留下追蹤信息素，這樣其它螞蟻也能去找到更多的食物”，哈普爾解釋道。
The pheromone trail gets reinforced every time an ant goes out and comes back, kind of like when you wear a trail in the forest to collect wood.
而這種追蹤信息素在每次覓食蟻出去再回來便會增強(qiáng)，有點(diǎn)像你在森林為了收集木材而做標(biāo)記。
