pill bug

基本解釋

In both the butterfly and the pill bug, the bacterium skews the populations' sex ratios massively toward females.
在非洲細(xì)蝶與鼠婦族群中，沃巴赫菌都大幅扭曲了性別比例，使雌性佔了絕對多數(shù)。
In the example of the pill bug, Thierry Rigaud and his collaborators at the University of Poitiers in France have shown that males prefer not to mate with feminized males.
至於鼠婦，法國波瓦提大學(xué)的黎哥與同事收集的資料，顯示雄性比較不喜歡與變性來的雌性交配。
For instance, males are extremely rare in some groups of the African butterfly Acraea encedon and of the widespread pill bug Armadillidium vulgare (also called a wood louse).
例如非洲細(xì)蝶（Acraeaencedon）的某些族群中，雄性極爲(wèi)稀少，分佈廣泛的鼠婦（Armadillidiumvulgare；又叫木虱）也是。
The defeat was a bitter pill to swallow.
那次失敗是一次難以吞咽的苦果。
Research by Rigaud and his associates has shown that Wolbachia can determine gender in A. vulgare, because male pill bugs have all the genes necessary to become females.
黎哥與同事已經(jīng)發(fā)現(xiàn)，沃巴赫菌能夠決定鼠婦的性別，因爲(wèi)雄性擁有發(fā)育成雌性所需要的全部基因。

a small, dark grey creature with a hard outer shell, found under stones or in slightly wet soil
