The role of dietary yeast in Drosophila melanogaster cellular immunity was investigated. Host larvae deprived of yeast immediately after parasitization by the cynipid wasp Leptopilina boulardi encapsulated a significantly lower percentage of the parasitoid's eggs than hosts transferred to a medium with yeast. When the transfers of hosts were made 24 hr after exposure to the parasite, diet had no effect on the immune response that had commenced prior to the transfers. This study demonstrates for the first time the effect of a specific dietary component on the immune responsiveness of Drosophila against a larval parasitoid.
研究了膳食酵母在黑腹果蝇细胞免疫中的作用。被瘿蜂科黄蜂布拉迪细蜂寄生后立即被剥夺酵母的宿主幼虫包裹的寄生蜂卵的百分比显著低于转移到含酵母培养基中的宿主。当宿主在接触寄生虫24小时后进行转移时，饮食对转移前就已开始的免疫反应没有影响。这项研究首次证明了特定膳食成分对果蝇针对幼虫寄生蜂的免疫反应性的影响。
