“…Females reared on a standard food were mostly seen on the balanced diet (P:C 1:1), reaching an estimated intake target of P:C 1:1.6. This estimation is similar to recent measures of intake targets by D. melanogaster based on actual consumption of liquid foods (Lee et al, 2013). Accordingly, females reared on an imbalanced diet P:C 1:16 (or P:C 8:1) were more often observed on a nutritionally complementary diet P:C 8:1 (or P:C 1:16), possibly in an attempt to compensate for their deficiency of one of the two nutrients.…”

“…Under this second hypothesis, oviposition choices may be primarily driven by the nutrient needs (nutritional state) of females. The strong preferences for laying eggs in high carbohydrate foods observed in previous studies (Rodrigues et al, 2015;Schwartz et al, 2012) may thus result from an attempt of flies bred on high protein diets to compensate for their deficit in carbohydrates (Lee et al, 2008(Lee et al, , 2013.…”

“…These effects of nutrition on physiology and behaviour greatly vary with age, sex and the mating status of individuals. For instance, when provided with nutritionally complementary diets, mated females and larvae balance their intake of protein (P) and carbohydrates (C) to reach P:C ratios maximising growth and reproduction [mated females P:C 1:1.5 (Lee et al, 2008(Lee et al, , 2013, larvae P:C 1:2 (Rodrigues et al, 2015)], whereas unmated females and males tend to consume more carbohydrates for energy [P:C 1:4 (Lee et al, 2013)]. Several studies also indicate that D. melanogaster females are highly selective when choosing oviposition sites (Yang et al, 2008).…”

Animals, from insects to humans, select foods to regulate their acquisition of key nutrients in amounts and balances that maximise fitness. In species in which the nutrition of juveniles depends on parents, adults must make challenging foraging decisions that simultaneously address their own nutrient needs as well as those of their progeny. Here, we examined how the fruit fly Drosophila melanogaster, a species in which individuals eat and lay eggs in decaying fruits, integrate feeding decisions (individual nutrition) and oviposition decisions (offspring nutrition) when foraging. Using cafeteria assays with artificial diets varying in concentrations and ratios of protein to carbohydrates, we show that D. melanogaster females exhibit complex foraging patterns, alternating between laying eggs on high carbohydrate foods and feeding on foods with different nutrient contents depending on their own nutritional state. Although larvae showed faster development on high protein foods, both survival and learning performance were higher on balanced foods. We suggest that the apparent mismatch between the oviposition preference of females for high carbohydrate foods and the high performances of larvae on balanced foods reflects a natural situation where high carbohydrate ripened fruits gradually enrich in proteinaceous yeast as they start rotting, thereby yielding optimal nutrition for the developing larvae. Our findings that animals with rudimentary parental care uncouple feeding and egg-laying decisions in order to balance their own diet and provide a nutritionally optimal environment to their progeny reveal unsuspected levels of complexity in the nutritional ecology of parent-offspring interactions.

“…When protein and carbohydrate are ingested in imbalanced quantities and ratios, insects suffer significant performance costs arising from ingesting not only too little of one nutrient (Mattson, 1980;White, 1993), but also too much of a nutrient that occurs in excess of their requirements (Simpson et al, 2004;Raubenheimer et al, 2005;Boersma & Elser, 2006;Zehnder & Hunter, 2009). For example, eating a diet containing excess protein relative to carbohydrate shortens lifespan in many insects (Lee et al, 2008(Lee et al, , 2013Fanson et al, 2012;Dussutour & Simpson, 2012).…”

Abstract. Ingesting nutritionally imbalanced food can cause a significant reduction in fitness in insects. Insects can avoid the negative consequences of nutritional imbalances by selectively foraging for nutritionally complementary foods. We investigated the ability of the omnivorous beetle, Tenebrio molitor (Coleoptera: Tenebrionidae), to redress nutritional imbalances by selecting complementary foods. Beetles were fed one of three synthetic diets that varied in their protein: carbohydrate balance (p0:c42, p21:c21 or p42:c0) for 16 days and then allowed to select between two nutritionally imbalanced but complementary diets (p0:c42 vs. p42:c0) for 18 days. During the initial period, beetle survival was high on all three experimental diets, but their body composition was considerably skewed as a result of eating nutritionally imbalanced diets. Over the first 6 days of food choice (days 16-22), beetles previously fed a protein-rich, carbohydrate-deficient diet (p42:c0) preferred carbohydrate to protein, whereas those previously fed a carbohydrate-rich, protein-deficient diet (p0:c42) strongly preferred the protein-rich diet. When the food choice period continued for longer than 6 days, the selection of diets by previously carbohydrate-deprived beetles (p42:c0) was similar to that of the control beetles previously fed an optimal food (p21:c21). However, beetles that were previously fed on the protein-deficient diet (p0:c42) selected protein and carbohydrate equally throughout the remaining period of food choice and the cumulative protein-carbohydrate intake of these protein-deprived beetles was similar to that of those fed the optimal diet (p21:c21). At the end of the experiment, the body composition of all beetles was similar, indicating that the effects of nutritional imbalance on body composition were buffered by the subsequent selection of complementary foods. Our results demonstrate that T. molitor beetles are capable of redressing nutritional imbalances and indicate that the way in which the nutritional balance of beetles is restored depends on the nutrient that is initially deficient in their food.

Resource-dependent evolution of female resistance responses to sexual conflict

et al. 2020

Sexual conflict can promote the evolution of dramatic reproductive adaptations as well as resistance to its potentially costly effects. Theory predicts that responses to sexual conflict will vary significantly with resource levels-when scant, responses should be constrained by trade-offs, when abundant, they should not. However, this can be difficult to test because the evolutionary interests of the sexes align upon short-term exposure to novel environments, swamping any selection due to sexual conflict. What is needed are investigations of populations that are well adapted to both differing levels of sexual conflict and resources. Here, we used this approach in a long-term experimental evolution study to track the evolution of female resistance to sexual conflict in the fruit fly Drosophila melanogaster. In resource-rich regimes, high-conflict females evolved resistance to continual exposure to males. There was no difference in baseline survival, consistent with the idea that responses evolving under nutritional abundance experienced no trade-offs with resistance. In the poor resource regimes, the ability of high-conflict females to evolve resistance to males was severely compromised and they also showed lower baseline survival than low-conflict females. This suggested highconflict females traded off somatic maintenance against any limited resistance they had evolved in response to sexual conflict.Overall, these findings provide experimental support for the hypothesis that evolutionary responses to sexual conflict are critically dependent upon resource levels.
