“…The absence of proteins in the adult food diet both delayed the ovarian maturation and decreased the fecundity of females. Similarly, Romanyukha et al (2004) and Nestel et al (2005) reported that the access to protein food sources significantly influences egg production and longevity in the Mediterranean fruit fly, C. capitata . Manrakhan and Lux (2006) , comparing three natural food sources, showed that fecundity was higher when Ceratitis fasciventris (Bezzi) and C. capitata females were fed on a protein-rich diet.…”

1. In phytophagous insects, life‐history traits mainly depend on host plant range. Substantial longevity, high fecundity and larval competition are the major traits of polyphagous Tephritidae while species with a restricted host range generally exhibit a lower longevity and fecundity as well as mechanisms to avoid larval competition. Our aim in this study was to investigate the life history of an oligophagous species, the tomato fruit fly, Neoceratitis cyanescens (Bezzi). 2. We determined life tables under laboratory conditions in order to calculate the main demographic parameters of N. cyanescens and studied the influence of larval and adult diet on life‐history traits. 3. The mean longevity of N. cyanescens females was 40 days. There was a strong synchronisation of female maturity. Oviposition showed an early peak at 9–13 days after a short pre‐oviposition period (6 days). The absence of proteins in the adult diet both delayed ovarian maturation and decreased female fecundity. In addition, females originating from tomato fruits produced significantly more eggs than females originating from bugweed or black nightshade, showing that even the larval host plant may strongly affect the subsequent fecundity of adult females. 4. The traits of N. cyanescens are then discussed in the light of those documented for polyphagous and monophagous tephritids. Neoceratitis cyanescens displayed attributes intermediate between those of polyphagous and monophagous tephritids. Its smaller clutch size compared with polyphagous species and its specialisation on the Solanaceae family whose fruits contain toxic compounds may help in reducing intra‐ and inter‐specific competition, respectively.

“…Consequently, adult diet should have an important effect on life‐history schedules and this has been well‐documented in many species (Tatar & Carey 1995; Chapman & Partridge 1996; Hunt et al . 2004b; Romanyukha et al . 2004; Hunt et al .…”

Effects of juvenile and adult diet on ageing and reproductive effort of male and female black field crickets, Teleogryllus commodus

et al. 2009

Summary 1.How and when resources are allocated to reproduction is expected to differ between the sexes, potentially generating differences in how males and females age. For this reason, acquisition of resources should be an important determinant of both age-dependent reproductive effort and of deteriorative ageing (i.e. senescence). 2. We used black field crickets, Teleogryllus commodus , to test whether differences in diet quality of juveniles and adults determine sex-specific resource allocation to reproduction and whether there are any subsequent effects on ageing. 3. We show that ageing does not depend on nymph diet. There was, however, a significant difference in the rates of actuarial ageing for males and females. Females showed reproductive ageing, whereas male reproductive effort plateaus or continues to increase with age. 4. These results highlight the link between diet, reproduction and ageing and show that differences in resource utilization between the sexes can lead to different patterns of ageing. This is likely to have profound effects on how life-histories evolve in the sexes.

Adaptation to divergent larval diets in the medfly,Ceratitis capitata

et al. 2016

Variation in diet can influence the timing of major life‐history events and can drive population diversification and ultimately speciation. Proximate responses of life histories to diet have been well studied. However, there are scant experimental data on how organisms adapt to divergent diets over the longer term. We focused on this omission by testing the responses of a global pest, the Mediterranean fruitfly, to divergent selection on larval diets of different nutritional profiles. Tests conducted before and after 30 generations of nutritional selection revealed a complex interplay between the effects of novel larval dietary conditions on both plastic and evolved responses. There were proximate‐only responses to the larval diet in adult male courtship and the frequency of copulation. Males on higher calorie larval diets consistently engaged in more bouts of energetic courtship. In contrast, following selection, larval development time, and egg to adult survival showed evidence of evolved divergence between diet regimes. Adult body size showed evidence for adaptation, with flies being significantly heavier when reared on their “own” diet. The results show the multifaceted responses of individuals to dietary selection and are important in understanding the extreme generalism exhibited by the medfly.
