The expression of life-history traits, such as lifespan or reproductive effort, is tightly correlated with the amount and blend macronutrients that individuals consume. In a range herbivorous insects, consuming high protein to carbohydrate ratios (P:C) decreases but increases female fecundity. other words, females face resource-based trade-off between Redox metabolism may help mediate this trade-off, if oxidative damage elevated by investment damage, in turn, reduces lifespan.

The interplay between nutrition and the microbial communities colonizing gastrointestinal tract (i.e., gut microbiota) determines juvenile growth trajectory. Nutritional deficiencies trigger developmental delays, an immature microbiota is a hallmark of pathologies related to childhood undernutrition. However, how host-associated bacteria modulate impact on remains elusive. Here, using gnotobiotic Drosophila melanogaster larvae independently associated with Acetobacter pomorumWJL (ApWJL) Lactobacillus plantarumNC8 (LpNC8), 2 model Drosophila-associated bacteria, we performed large-scale, systematic nutritional screen based larval in 40 different precisely controlled environments.

Abstract Animals have evolved foraging strategies to acquire blends of nutrients that maximize fitness traits. In social insects, nutrient regulation is complicated by the fact few individuals, foragers, must address divergent nutritional needs all colony members simultaneously, including other workers, reproductives, and brood.

Abstract A better understanding of the factors affecting host plant use by spotted-wing drosophila (Drosophila suzukii) could aid in development efficient management tools and practices to control this pest. Here, proxies both preference (maternal oviposition behavior) performance (adult emergence) were evaluated for 12 different fruits form purees. The effect chemical composition on traits was then estimated. We synthesized literature interpret our findings light previous studies that measured larval D. suzukii. show fruit identity influences parts life cycle, including under choice no-choice conditions, emergence rate, time, number emerging adults. Blackcurrant always among most preferred we used, while grape tomato least fruits. Larvae performed cranberry, raspberry, strawberry, cherry than other tested. found compounds can explain part suzukii traits. In particular, conditions strongly influenced phosphorus content. general, consensus across is blackberry, strawberry are best hosts blackcurrant, rose hips poor hosts.

Nutrition is a major factor influencing many aspects of Drosophila melanogaster physiology. However, wide range diets, which are termed "standard" in the literature, utilized for D. research, leading to inconsistencies reporting nutrition-dependent phenotypes across field. This especially evident microbiome studies, as diet has pivotal role composition and resulting host-microbe interactions. Here, we performed meta-analysis diets used fly research provide web-based tool researchers determine nutritional content interest. While our primarily focuses on goal developing these resources aid broader community contextualizing past future studies scope better understand how individual lab can contribute observed phenotypes.

The adaptive significance of phenotypic changes elicited by environmental conditions experienced early in life has long attracted attention evolutionary biology. In this study, we used Drosophila melanogaster to test whether the developmental diet produces phenotypes better adapted cope with similar nutritional later life. To discriminate among competing hypotheses on underlying nature plasticity, employed a full factorial design several and adult diets. Specifically, examined effects early- late-life diets (by varying their yeast sugar contents) reproductive fitness amount energy reserves (fat glycogen) two wild-caught populations.We found that individuals had developed either low-yeast or high-sugar showed decreased performance regardless environment. lower might be caused smaller body size reduced ovariole number. Overall, these results are consistent silver spoon concept, which posits development suboptimal environment negatively affects fitness-associated traits. On other hand, higher (fat) represent an response side-effect compensatory feeding.Our findings suggest observed differences physiology induced early-life likely result from inevitable general nutrition metabolic organs, rather than mechanisms.
