“…While dietary protein is essential in females for egg production, the male flies require relatively little or no protein during adulthood [52, 56]. However, ingestion of proteins above a certain threshold level, especially by males, has a detrimental/toxic effect on longevity and fitness, suggesting that flies have poor tolerance for over-consumption of proteins [57]. In females, diets with relatively high yeast: carbohydrate ratios tend to increase egg production, whereas those with high carbohydrate:yeast ratios result in longer life span [52, 58].…”

The main objective of this review is to provide an appraisal of the current status of the relationship between energy intake and the life span of animals. The concept, that a reduction in food intake, or caloric restriction (CR), retards the aging process, delays the age-associated decline in physiological fitness and extends the life span of organisms of diverse phylogenetic groups, is one of the leading paradigms in gerontology. However, emerging evidence disputes some of the primary tenets of this conception. One disparity is that the CR-related increase in longevity is not universal and may not even be shared among different strains of the same species. A further misgiving is that the control animals, fed ad-libitum (AL), become overweight, prone to early onset of diseases and death, and thus may not be the ideal control animals for studies concerned with comparisons of longevity. Re-examination of body weight and longevity data from a study involving over 60,000 mice and rats, conducted by a National Institute on Aging-sponsored project, suggests that CR-related increase in life span of specific genotypes is directly related to the gain in body weight under the AL feeding regimen. Additionally, CR in mammals and “dietary restriction” in organisms, such as Drosophila, are dissimilar phenomena, albeit they are often presented to be the very same. The latter involves a reduction in yeast rather than caloric intake, which is inconsistent with the notion of a common, conserved mechanism of CR action in different species. Although specific mechanisms by which CR affects longevity are not well understood, existing evidence supports the view that CR increases the life span of those particular genotypes that develop energy imbalance due to AL feeding. In such groups, CR lowers body temperature, rate of metabolism and oxidant production, and retards the age-related pro-oxidizing shift in the redox state.

“…In the wild, adult tephritids have been recorded acquiring their nutrients from different food sources: fruit juice, nectar, pollen, extrafloral glandular secretions, honeydew, bird feces, and bacteria (Drew, Courtice, & Teakle, 1983; Hendrichs, Lauzon, Cooley, & Prokopy, 1993; Manrakhan & Lux, 2006). Due to their economic impact on fruit trade, the link between nutrition, reproduction, and lifespan has been relatively well studied in generalist tephritids using dietary manipulations, where hydrolyzed yeast was used as a source of protein (Carey et al., 2008; Fanson, Weldon, Perez‐Staples, Simpson, & Taylor, 2009; Harwood et al., 2013; Liedo, Carey, Ingram, & Zou, 2012; Oviedo et al., 2011). However, as hydrolyzed yeast is a mixture of macro‐ and micronutrients, it is preferable to use protein only (a mixture of amino acids) to ensure that the observed effect can be attributed to the macronutrient and not to the quality of the industrial yeast (Fanson & Taylor, 2012; Piper & Partridge, 2007).…”

In insects, lifespan and reproduction are strongly associated with nutrition. The ratio and amount of nutrients individuals consume affect their life expectancy and reproductive investment. The geometric framework (GF) enables us to explore how animals regulate their intake of multiple nutrients simultaneously and determine how these nutrients interact to affect life‐history traits of interest. Studies using the GF on host‐generalist tephritid flies have highlighted trade‐offs between longevity and reproductive effort in females, mediated by the protein‐to‐carbohydrate (P:C) ratio that individuals consume. Here, we tested how P and C intake affect lifespan (LS) in both sexes, and female lifetime (LEP), and daily (DEP) egg production, in Ceratitis cosyra, a host‐specialist tephritid fly. We then determined the P:C ratio that C. cosyra defends when offered a choice of foods. Female LS was optimized at a 0:1 P:C ratio, whereas to maximize their fecundity, females needed to consume a higher P:C ratio (LEP = 1:6 P:C; DEP = 1:2.5 P:C). In males, LS was also optimized at a low P:C ratio of 1:10. However, when given the opportunity to regulate their intake, both sexes actively defended a 1:3 P:C ratio, which is closer to the target for DEP than either LS or LEP. Our results show that female C. cosyra experienced a moderate trade‐off between LS and fecundity. Moreover, the diets that maximized expression of LEP and DEP were of lower P:C ratio than those required for optimal expression of these traits in host‐generalist tephritids or other generalist insects.

“…Much of the research that has been conducted during the last decade to develop mass-rearing protocols has been focused on establishing laboratory colonies particularly aiming at increased egg production (Jaldo, 2001;Jaldo et al, 2001;Vera et al, 2007) and improved adult feeding (Oviedo et al, 2011). Still, the larval diet most widely used to rear A. fraterculus is the one developed by Salles (1995).…”

Mass-rearing protocols must be developed, in particular, a cost-effective larval diet, to implement the sterile insect technique against Anastrepha fraterculus (Wiedemann).The key elements of this diet are the optimal nutrients and their concentrations, diet supports or bulking agents, and the pH of the diet. To improve the currently used formulation and develop a more cost-effective diet, in the present study, we evaluated various supports, sugar contents, nutrient proportions and pH levels. Egg-to-pupa recovery was found to increase when agar was replaced with sponge cloth in the diet. Although low, the recovery values obtained when using the sugarcane bagasse-based diet were similar to those obtained when using the agar-based diet, but the percentage of adult emergence was lower. Larval viability was found to increase when the amount of sugar in the diet was doubled. Yet, it is still necessary to evaluate this diet on a larger scale and determine the feasibility of reusing the sponge cloth to reduce the costs of larval diets.
