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.

Life‐history trade‐offs under different larval diets in Drosophila suzukii (Diptera: Drosophilidae)
Most larval drosophilids eat the microorganisms that develop in rotting fruit, a relatively protein‐rich resource. By contrast, the spotted‐wing Drosophila suzukii Matsumara (Diptera: Drosophilidae)
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


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.
Maternal effects increase survival probability in Drosophila subobscura larvae
Exposure to yeast‐fed and mated females that deposited eggs on the fruits led to a significant increase in the survival probability of the transferred larvae to the adult stage, and an active inoculation of the breeding substrates with yeast by ovipositing females was suggested.
Clash of kingdoms or why Drosophila larvae positively respond to fungal competitors
Social attraction of Drosophila larvae to fungal-infected sites leading to suppression of mould growth may reflect an adaptive behavioural response that increases insect larval fitness and can be discussed as an anti-competitor behaviour.
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.
Larval selectivity for yeast species by Drosophila mojavensis in natural substrates.
Larvae of D. mojavensis appear to be ecological (host plants) generalists and physiological (yeasts) specialists in contrast to the other cactophilic Drosophila, and selective feeding in natural substrates may represent optimal foraging behavior.
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.
