Summary
The yeast florae in the natural substrates of four desert and three non-desert Drosophila species were compared both qualitatively and quantatively to the yeast present in the guts of Drosophila larvae living in those substrates. The desert species breed in rotting cacti and the other Drosophila were found breeding in necrotic oranges. Larvae of one cactophilic species, D. mojavensis, and larvae of all of the species utilizing oranges (D. melanogaster, D. pseudoobscura, and D. arizonensis) were found to contain non-random samples of the yeasts available in their respective substrates. Larval preference behavior is most likely responsible for these differences. The other cactophilic Drosophila (D. nigrospiracula, D. mettleri, and D. pachea) did not exhibit significant differences when the yeast florae of their larvae and substrates were compared. Selective feeding by larvae appears to be related to the degree of polyphagy in that only larvae of polyphagous species are selective. Trade-off between generalism and specialism at two biological levels is discussed.
