“…The age of mating individuals is apparently a key factor in reproduction with effects on their sexual performance and progeny production (Pervez et al 2004). The investigations on the effects of age on life events in insects include mate choice, mating incidence, activity levels and reproduction.…”

Male age influence on male mating success, courtship, mating activities, fecundity, fertility, longevity, percentage of egg-larval hatchability and percentage of larva-adult viability has been studied in Drosophila ananassae. It was noticed that females of D. ananassae were able to discriminate males on the basis of male age and preferred to mate with old-aged males more frequently than younger or middle-aged males using a female choice experiment. Old-aged males significantly mated faster, performed greater courtship activities, copulated longer and inseminated more females in a given unit of time, showed greater fecundity, fertility, percentage of egg-larval hatchability, percentage of larva-adult viability, and females mated to old-aged males lived shorter than those mated to younger or middle-aged males. Thus in D. ananassae females discriminate males on the basis of age and females mated to old-aged males had significantly greater reproductive success than that of females mated to younger or middle-aged males.

“…For example, virgin female cockroaches became less selective in choosing their partners with increasing age (Moore & Moore 2001). Middle aged and old female ladybird beetles preferentially mate with the middle aged and older males (Pervez et al 2004). Virgin female European grapevine moths display decreased fecundity and fertility if mated later in life but have increased survivorship (Torres-Vila et al 2002).…”

Mating alters the physiology and behavior of female Drosophila melanogaster resulting in a surge of egg laying, a decrease in receptivity to other males, and a decrease in life span. Here, we show striking differences in patterns of Drosophila egg laying and mortality rate dependent upon mating history. Our data reveal previously unreported epochs in the reproductive life of females: optimal, vulnerable and declining-terminal. During the optimal period, mating induces females to respond with a surge in egg laying and has a reversible effect on mortality rate. In contrast, during the vulnerable period, mating does not induce females to respond with a surge in egg laying and causes an irreversible increase in mortality rate. The terminal period was always observed several days before death, irrespective of the chronological age, and is marked by sharp reductions in egg laying. The presence of these distinctive biological epochs may reflect increased female sensitivity to mating due to age-related decline.

Abstract. The ageing trajectory (trend in ageing) and reproduction-longevity trade-off in both sexes of the ladybird Propylea dissecta were studied. The ageing trajectories of both sexes were investigated in terms of reproductive performance, using initial oviposition (egg laying within 24 h of mating) acting as an indicator of the effect of female age and initial viability (percentage of eggs laid within 24 h of mating that hatched) of the effect of male age. Ageing trends were sex dependent, with reproductive performance declining later in females than in males. Initial oviposition of females was largely age dependent and the initial viability of males was age dependent but less so than for females. There is a strong trade-off between number of matings and longevity. Statistical analyses reveal that this trade-off results from an early onset of mortality rather than an increase in mortality rate. A minimum lifespan was observed in this ladybird beyond which the longevity did not further decline.
