“…As expected for Tephritidae fruit flies (see for example, Webster et al, 1979;Jacome et al, 1995;Carey et al, 1998Carey et al, , 2002, females feeding on a full adult diet mix, which includes protein hydrolyzate, produced severalfold more eggs than females fed on sucrose only. Moreover and as previously shown (Carey et al, 2002), protein-fed female medflies were able to maintain egg production throughout most of their adult life, with an intensive egg-laying stage early in adult life, which declined with age.…”

Survival and egg-laying trends were investigated in Mediterranean fruit flies (Ceratitis capitata) adults maintained on a sucrose-only diet, or on a full diet that consisted of a 3:1 sucrose and yeast hydrolizate mixture. In addition, we followed the total individual lipid and protein contents of aging flies in a cohort. Survival trends and life expectancy parameters at eclosion for males and females on full diet and for males on sucrose only were very similar. In contrast, the mortality of females on sucrose only was high early in life, but then slowed down. Egg-laying was ten times greater in female flies on full diet than in flies on sucrose only. Lipid contents in males and females on both types of diets were very similar, and harmonically oscillated with an amplitude of approximately 10 days. Successive crests of lipids tended to be smaller with the ageing of the cohort, and lipids contents significantly dropped at very advanced ages and close to the maximal age of the whole cohort. Protein contents of flies maintained on a full diet were high and stayed at a constant level throughout the entire life of the cohort. Protein levels in males and females on sucrose only dropped drastically during the first days of adult life, but then stayed stable at a low level until advanced ages. We propose that the synchronous rhythmic oscillation in lipid contents of male and female flies seems to be independently set by an internal clock. Protein reserves are allocated according to the access to protein food sources and these levels of protein are closely associated to egg production and mortality. Our results are discussed in view of resource allocation during reproduction and senescence.

“…These flies feed on protein and carbohydrate sources as adults (Webster et al, 1979). I hypothesize that these resources must be partitioned between investment into maturation and maintenance of eggs versus somatic maintenance and repair.…”

SummaryThe hypothesis was tested that egg-laying by rosehip fruit flies, Rhagoletis basiola, would lead to reduced adult survivorship compared with oviposition-deprived flies, through experimental manipulation. Oviposition-deprived flies were assigned to two groups: mated and spinster. All three treatment groups were permitted to spend equal time and energy exploring and handling hosts but only the former group were allowed to deposit eggs (three/day). Results clearly showed that ovipositing flies suffered significantly higher mortality rates and that mated and spinster flies produced similar survivorship patterns. I consider these results both as a foraging problem (i.e. laying eggs in inferior hosts can cost both eggs and life) and as a more general life history problem.

“…Although the degree of variability in trail area is high even among successive dragging bouts by the same female, we have found through sufficient replication that starved or older (28 day) females deposit significantly less trail substance than fed or younger (14 day) females, and that females deposit just as much trail substance on small (12 mm) or ODP-marked hawthorne fruit as on large (19 mm) or clean fruit (Averill and Prokopy, 1980a). Inasmuch as the gut is the principal or exclusive site of accumulation of the principal ODP component, and inasmuch as food consumption by 28-day females is substantially less than that by 14-day females (Webster et al, 1979), it is not surprising that starved or older flies should release less ODP trail substance.…”
