昆虫两个重要激素（蜕皮激素和保幼激素）协调调控昆虫的变态发育。其中蜕皮激素由胆固醇衍生而来，而昆虫并不能从头合成胆固醇，必需从食物中摄取固醇类物质，转变成胆固醇后再以胆固醇为前体合成蜕皮激素。然而，在动物界中，哪些动物能够从头合成胆固醇，哪些动物不能从头合成胆固醇，有没有一定的模式，该模式在动物界中又是怎么样起源、进化和维持的，具有什么样的进化意义，这个巨大的谜团已经困扰了动物学家和进化生物学家数...

An international team of researchers, including those from Princeton University, reported that a certain species of bees, called halictid bees, have more sensorial machinery compared with re...
The seemingly peaceful atmosphere in an organic garden on the University of Florida campus belies the battles happening among many of its tiniest inhabitants -- the insects. For entomologist Christine...
As an National Science Foundation (NSF)-funded entomologist, Virginia Tech's Paul Marek has to spend much of his time in the field, hunting for rare and scientifically significant species. He's provid...
For most of us, switching to a vegetarian diet might be a matter of a New Year's resolution and a fair amount of willpower, but for an entire species, it's a much more involved process — one that evol...

Under the Dobzhansky-Muller model, postzygotic isolation results from incompatibility between interacting genes. Evidence points to regulatory networks as a rich source of incompatibilities that impac...
