| 摘 要： | 初生内共生菌与宿主蚜虫的营养代谢密切相关.本文观察了蚕豆蚜Aphis fabae不同翅型的共生菌胞随宿主蚜虫生长发育的变化规律,以及饥饿和混合柄瘤蚜茧蜂Lysiphlebus confusus寄生对共生菌胞的影响.菌胞数量和体积随发育进程和翅型的变化而呈现有规律的变化:随若蚜发育而逐渐增大,然后随胎生蚜产生而逐渐减少;无翅蚜的菌胞数量和体积均显著大于有翅蚜.随饥饿时间的延长,菌胞数量和体积迅速直线下降,而重新取食后又可迅速恢复.蚕豆蚜被混合柄瘤蚜茧蜂寄生后的第3d,菌胞数量显著多于未寄生蚜虫,此后则明显少于未寄生蚜虫,从第4d的119个·头-1降至第6d的46个·头-1.研究结果说明,蚜虫共生菌胞的变化与宿主蚜虫翅型、发育、外源营养以及蚜茧蜂寄生等密切关联.

| Abstract: | Primary endosymbiotic bacteria are obligate for nutritional metabolism in host aphids.Changes of mycetocytes along with aphid development in different morphs and as affected by starvation and parasitism were observed in this paper.The number and volume of mycetocytes varied with age and morph,increasing with early larval growth and then gradually declined with embryo production.The number and volume of mycetocytes were not different within 3 days after birth,but then greater in apterous than in alate morphs... |
