An organism’s fitness is highly dependent on resource quality. The diet of saprobiotic organisms often comprises a variety of microorganisms. Saprophagous Drosophila melanogaster Meigen (Diptera: Drosophilidae) is known to feed on various yeast species, both as larva and adult. The yeasts encountered by the insects may differ in composition and quality, and thus in their influence on larval and adult performance. Our study explores life‐history consequences of larval diet on selected larval and… 
Live yeast in juvenile diet induces species-specific effects on Drosophila adult behaviour and fitness
The results indicate that specific yeast species present in natural food sources and ingested by larvae can affect their adult characters crucial for fitness.
Differential Impacts of Yeasts on Feeding Behavior and Development in Larval Drosophila suzukii (Diptera:Drosophilidae)
It is demonstrated that yeast plays a critical role in D. suzukii’s ecology and that larvae may have developed specific yeast associations, and that they performed most poorly on diets containing H. uvarum, a mismatch in preference and performance that suggests differences in yeast nutritional quality are not the primary factor driving larval feeding behavior.
The Effect of Nutritive Yeasts on the Fitness of the Fruit Fly Drosophila melanogaster (Diptera: Drosophilidae)
The hypothesis that different nutritive yeast species affect Drosophila survival rate, decrease development time and increase resistance to infection is supported, providing evidence that the fitness of Drosophile critically depends on the fly's genotype as well as the nutritive yeasts.
Dietary yeast affects preference and performance in Drosophila suzukii
A crucial role of dietary yeast in the larval development and survival of D. suzukii is confirmed and specific effects of the closely associated yeast species H. uvarum and Candida sp.
Yeast species affects feeding and fitness of Drosophila suzukii adults
Yeasts play an important role in the life cycle and biology of the insect pest Drosophila suzukii (Matsumura), commonly known as the spotted wing drosophila (SWD). Adult and larvae of this species
Dietary live yeast alters metabolic profiles, protein biosynthesis and thermal stress tolerance of Drosophila melanogaster.

Determination of the effects of two feed supplements on Drosophila melanogaster
Pleurotus spp. are considered extremely rich mushroom species from the nutritional pointof view, providing immune-enhancement effects when consumed. However, few mushroomshave been tested for their
Nutrient-Dependent Impact of Microbes on Drosophila suzukii Development
The microbiota of field-captured and laboratory-reared D. suzukii flies was investigated and it was found that proteins are limiting with respect to fly development on fruit-based diets and that GF flies show signs of protein starvation, showing that the impact of microbes on fly fitness depends strongly on nutritional conditions.


Saprophagous insect larvae, Drosophila melanogaster, profit from increased species richness in beneficial microbes
Not only yeast diversity had an effect on D. melanogaster life‐history traits, but also the identity of the yeast combinations, demonstrating the importance of the structure and diversity of microbial communities in mutualistic animal–microbe interactions.
Comparisons of yeast florae from natural substrates and larval guts of southwestern Drosophila
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 Drosophile larvae living in those substrates, finding selective feeding by larvae appears to be related to the degree of polyphagy.
The coexistence of seven species of Drosophila in the fruit and vegetable market was explained by the partitioning of breeding sites and by the fact that the community may never reach equilibrium.
A Minimalist Approach to the Effects of Density- Dependent Competition on Insect Life-history Traits
This minimalist approach may provide a useful model for investigating the effects of density-dependent competition on insect life-history traits and the role of nutritional reserves for the reproductive success of males was highlighted in particular.
Effects of microbial floras on the distributions of five domestic Drosophila species across fruit resources
It is proposed that the clear partitioning of the fruit resources by the Drosophila is due to their differing primary interactions with the microflora.
Environmental Modification of Oviposition Behavior in Drosophila
In order to assess the independent effects of larval and adult environments on oviposition site preference in four species of Drosophila, individuals were exposed as larvae and/or adults to medium containing sodium chloride, ethanol, ethyl acetate, lactic acid, piperidine, or peppermint oil.
Oviposition and feeding on naturally occurring yeasts by Drosophila spp., using natural substrates
A narrowing of this "fundamental" niche by ovipositional preferences particularly for substrate type, was seen in Drosophila phalerata Meig.
The role of yeasts as insect endosymbionts.
Several interesting symbiotic associations occur between insects and yeasts, and the benefit that accrues for the insect is better understood than the benefit to the yeasts.
The present investigation is primarily an attempt to study the attractivity of different species of yeast to larvae of different Drosophilae, and finds that different yeast species are unequal in attractiveness to differentspecies of Drosophile flies.
Yeast communities of the cactus Pilosocereus arrabidae as resources for larval and adult stages of Drosophila serido.
The feeding behavior of Drosophila serido on the yeast communities of necrotic stem tissue of Pilosocereus arrabidae were studied and suggested that there was food selection and diet partitioning between adult and larval stages of D. serido.
