【摘要】 对亚洲玉米螟,Ostrinia furnacalis(Guenee)(Lepidoptera:Pyralidae),末龄滞育幼虫的生理生化指标进行了研究。确定了血淋巴滞育关联蛋白的分子量,微量呼吸仪测定了幼虫的呼吸量。同时,对体内水分含量,幼虫对水的耐受性,以及雄性精巢的大小亦进行了分析和观察。发现相应于非滞育幼虫,滞育幼虫有如下特点:1.滞育幼虫的血淋巴中具有一种滞育关联蛋白,它的两个亚肽的分子量分别为72000和840000道尔顿。2.雄性生殖器官发育不完全。3.体内水分含量占体重的比率较低,相对应干重较高。4.在室温下对浸水窒息的耐受性高。5.幼虫呼吸微弱,氧的消耗较小。更多还原

【Abstract】 The physiological and biochemical characteristics of the diapause larvae of Asian corn borer Ostrinia furnacalis , were investigated. The molecular weight of diapause associated protein in hemolymph was determined. The development of male reproductive system, the body water content, the tolerance to suffocation and the rates of respiration of the diapause and non-diapause larvae were compared. The results revealed that the diapause larvae have the following characteristics: 1. There is a diapause associated protein in heamolymoph; its molecular weights of two polypeptide chains are 72,000 and 84,000 Dal. respectively. 2. The male reproductive organ is underdeveloped. 3. The body water content is lowered. 4. A much higher tolerance to suffocation is exhibited after submergence under water at room temperature. 5. A low rate of respiration prevailed.更多还原
