To clarify the coexistence mechanism between Japan-origin invasive and aggressive predator Harmonia axyridis and the related species, field and laboratory experiments were performed. From the field survey, H. axyridis was the most common among the aphidophagous predators at many invaded areas. The sibling species H. yedoensis sympatrically coexists with H. axyridis only on a pine tree to specialize at morphological and behavioral traits. The asymmetric mating interference in H. axyridis plays an important role on the limited habitatof H. yedoensis and the large habitat of H. axyridis.

为阐明日本源入侵性和攻击性天敌异色瓢虫与近缘种的共存机制，进行了野外和室内实验。通过实地调查，H.异色瓢虫是许多入侵区食蚜性天敌中最常见的一种。姊妹种H. yedoensis与H.只有松树上才有异色瓢虫专门研究形态和行为特征。非对称交配干扰在H. axyridis对H. yedoensis和H.异色。
