1. 为了阐明寄主专门化进化的因素，研究了两种瓢虫兄弟种——yedoensis Harmonia和H. axyridis的幼虫捕食四种蚜虫的行为。红杉是一种专门捕食者，只捕食野外的松蚜虫，而灰蚜是一种多面手捕食者，猎物范围很广。
1. To elucidate the factors responsible for the evolution of host specialisation, prey capture performance in hatchlings of two sibling ladybird species, Harmonia yedoensis and H. axyridis, feeding on four aphid species was examined. Harmonia yedoensis is a specialist predator that preys only on pine aphids in the field, whereas H. axyridis is a generalist predator with a broad prey range.
