| 5. | The results were showed as follows : the synthesis and uptake of vg of this parasitic wasp respectively initiated since the 10th and 13th day after parasitism , which were equivalent to the first pupal stage and the pharate adult stage of this parasitic wasp
结果表明，该蜂卵黄原蛋白的合成与摄取分别起始于寄生后的第10d和第13d ，即正处于该蜂的蛹初期和隐成虫期。 |
| 6. | Pupal hemolymph infected with recombinant virus bmpak - hbmp and bmpak - hbm showed four protein bands of about 31 , ' 30 , 28 and 25 kd in the western blotting profiles , due to the two atg initial codons at the 5 " ends of both pres2 and s gene
Western杂交结果表明，感染bmpak hbmp和bmpak hbm的家蚕蛹血淋巴中均有4种不同分子量的蛋白质和鼠抗人的一抗发生免疫反应，大小约分别为31kd 、 30kd 、 zskd 、 25kd 。 |
| 7. | Natural enemies of hyphantria cunea ( drury ) were investigated in qinhuangdao , hebei province . two parasitoids in larva stage , 12 parasitoids in pupal stage and 2 predators ( coccinella septempunctata and tenodera sinensis ) were found
摘要通过对美国白蛾各个发育期的天敌进行调查与研究，发现除了捕食性天敌七星瓢虫、大刀螳螂等外，幼虫期有2种寄生性天敌、蛹期有12种寄生性天敌，这为保护和利用天敌、有效控制美国白蛾提供了依据。 |
