【英语时差8,16】走开！

Don: Arghh. Stupid bees! Yaël: Are you sure those are bees Don? D: Well I'd say they're either bees or wasps². But I'm not sure. Y: Well I think most people couldn't tell wasps or bees apart by sound. And we're not alone! A study shows that some leaf-eating caterpillars³ can't tell the difference between wasps and bees by sound either. D: Bees don't usually hurt caterpillars, but don't some wasps eat those hairy little guys? Y: They sure do. And this study showed that when some caterpillars hear buzzing nearby they stop their leaf munching⁵ and head for the hills, because they don't know if the buzz maker⁷ is a harmless bee or a predatory wasp¹. D: That's too bad for the caterpillars, but it sounds like good news for the plant since the caterpillar⁴ doesn't munch⁶ on so many of its leaves if there's a bee nearby. Y: Exactly. The study found that fruitless plants sustained sixty- to seventy-percent less leaf damage by caterpillars when bees were around then when the caterpillars were left alone with the leafy greens. D: So bees are pulling double duty for plants: not only do they pollinate flowering ones but they also scare off plant eating bugs⁸ from plants within earshot of the bees'buzzing. Y: Indeed. And with this finding we might someday be able to improve food production;since if we could get more bees buzzing around our crops, scaring off pests, we might get higher yields using fewer pesticides⁹.
