在索诺兰沙漠的两个地点[墨西哥的BOJA加利福尼亚和美国的亚利桑那州]，从果蝇、苍蝇、仙人掌宿主和其他邻近来源的嗜食酵母菌中采集酵母样本，以确定苍蝇携带的酵母与其繁殖地发现的酵母之间的关系。D.莫杰文氏菌。Nigrospiracula和D.mettleri携带的酵母菌组合与收集苍蝇的腐烂上发现的酵母物种显著相似，而不是在同一地点寄主仙人掌或其他腐烂仙人掌的苍蝇上发现的酵母相似。有果蝇的腐烂比没有果蝇的腐烂的酵母菌种类更少，这表明苍蝇与较年轻的腐烂有关。有果蝇和果蝇的腐烂比没有果蝇的腐烂有更多的酵母种类，能够产生乙酸乙酯。这一结果支持这样一种观点，即嗜食果蝇以某一地区可用酵母的子集为食，并可能维持不同种类仙人掌上发现的酵母群落的差异。
At two locations in the Sonoran Desert [Boja California, Mexico and Arizona, USA], yeasts were sampled from species of Drosophila, the flies cactus hosts, and other neighboring sources of cactophilic yeasts to determine the relation between the yeasts vectored by the fly and the yeasts found in their breeding sites. D. mojavensis. D. nigrospiracula, and D. mettleri vectored yeast assemblages significantly more similar to the yeast species found on the rot from which the flies were collected than to the yeasts found on other rots from the flies host cactus or other rotting cactus at the same site. Rots with Drosophila had fewer yeast species than those without flies, suggesting that flies were associated with younger rots. Rots with flies and the Drosophila also had more yeast species with the capability to produce ethyl acetate than rots without flies. The results support the contention that cactophilic Drosophila feed on a subset of the yeasts available in an area, and may act to maintain differences among the yeast communities found on different species of cactus.
