【摘要】 在30℃、35℃及75%RH条件下,研究四纹豆象和绿豆象中一种豆象的雄虫及卵对另一种豆象成虫产卵的影响.结果表明:一种豆象雄虫及卵的存在导致另一种豆象雌成虫产卵量下降,下降幅度绿豆象明显大于四纹豆象,说明在两种豆象的产卵竞争当中,四纹豆象占据一定优势.更多还原

【Abstract】 Under the conditions of 30 ℃,35 ℃ and 75%RH,the mutually interferential oviposition of Callosobruchus maculatus and Callosobruchus chinensis caused by another kind of male adult and egg was studied.The results indicated that the egg and male adult existence of one bruchid species led to a fall in oviposition of another bruchid species.The declining range of oviposition of C.chinensis is wider than that of C.maculatus,which proved that C.maculatus is a dominant species in the ovipositin competition between C.maculatus and C.chinensis.更多还原
