【摘 要】
：
爱吃害虫的瓢虫是园丁们的好帮手,但那只是在它们的幼虫时期。一旦它们长上了翅膀就会飞走,不再顾及灭害虫了。现在法国科学家培育了不会飞的瓢虫,能较长期地充当害虫杀手。

Ladybugs that love pests are a good helper for gardeners, but it was only during their larvae. Once they have wings, they fly off and no longer care about pests. Now French scientists have cultivated flightless ladybugs that can act as pest killers for a longer period of time. 】
