摘　　要：本研究通过混合竞争实验、互相产卵实验和不同着卵量下的成虫卵巢可见卵量观察实验，得出在四纹豆象与绿豆象种群竞争中，四纹豆象占优势的结论。混合竞争实验，虽然在绿豆象发育最适温度30℃条件下进行，但绿豆象在竞争中仍处于劣势。由此充分说明四纹豆象是一种危险性害虫，应加强对该虫的检疫。In population competition between Callosobruchus maculatus Callosebruchus chinensis and Callosebruchus maculatus was dominant through the experiments of mixing competition, crossing ovipesition and the number of the visual eggs from the ovary of female which emerged under the condition of different number of eggs. Though mixing competition experiment at conditbo of 30℃ (the fittest to the growth of ChllohorUChus chinensis), Callosobruchus chinensis was not yet dominant. So Callosobruchus maculatus was a kind of dangerous insects.
