俗称为花大姐的瓢虫,是一种非常贪吃的昆虫,因此人们经常在专门的生物工厂繁殖它并释放到被害虫(尤其是蚜虫)侵袭的菜园。然而它也有个缺点一会飞走。为克服这一缺陷,法国遗传学家借助辐射及化学诱变物质,培育出了不会飞的瓢虫。由人工选择的诱变体而产生了一种新甲虫变体,它们中有95%都不能飞行。尽管它们有正常的翅膀,食量也很大,也能繁殖后代,但只能爬行,就是不会飞。这种新瓢 Ladybug, commonly known as Sister Flower, is a very greedy insect, so people routinely multiply it in specialized biological plants and release it to vegetable gardens infested with pests, especially aphids. However, it also has a disadvantage for a while to fly away. To overcome this flaw, French geneticists have used radiation and chemical mutagens to breed ladybugs that do not fly. A new variant of the beetle was created by the artificial selection of mutants, 95% of which were not allowed to fly. Although they have normal wings, they also eat well and can breed offspring, but they can only crawl and never fly. This new scoop
