“…However two types of mechanisms should be considered: variations of the synthetic capacities can occur as a consequence of modifications of digestive or of fat body cells. Other results (Cohet and Boul6treau-Merle, 1974;Barker and Herman, 1976;Papillon et al, 1976) also suggest that the neuroendocrine cells, and therefore the production of hormones, could be modified.…”

Drosophila melanogaster larvae were reared at various constant temperatures ranging from 12° C to 32° C and adults were transferred at the usual temperature of 25° after emergence. Daily egg production and egg hatchability were measured for the whole lifetime. The adults, of the same average genotype and kept in identical conditions, showed considerable variation in reproductive capacity. For adults grown at an optimum temperature (21° or 25°) the number of offspring produced was about 2500; this number dropped below 500 when development took place either at a lower or higher temperature. Several physiological changes explain these deleterious effects: male sterility at low or high temperature, variation in ovariole number, and in rates of oogenesis and senescence. Only the male sterility was cured by the return to 25°; all the other modifications were permanent. The significance of this epigenetic load in the life strategy of the species is discussed.

“…Together with the empirical work by Singer (1982), Pilson and Rausher (1988), and Odendaal (1989), it suggests that studies of egg load or associated factors may help explain insect behavioral responses. Furthermore, since environmental conditions affect egg development (e.g., Stern and Smith, 1960;Rankin, 1974;Barker and Herman, 1976;Gossard and Jones, 1977;Pouzat, 1978), egg load and associated physiological factors may form a mechanistic link between environmental stimuli and female behavior. Studies on vertebrates have already shown that the internal physiological state commonly mediates the response of individuals to external stimuli (for review, see Farner et al, 1971Farner et al, -1983Carter, 1974;Lofts, 1974;Rankin et al, 1983;Van Tienhoven, 1983;Pitcher, 1986).…”

Numerous studies have documented the influence of environmental factors such as host plant species and host quality on the oviposition behavior of female insects. This paper shows that an internal physiological factor, the number of mature eggs a female carries (egg load), correlates with host selectivity and clutch size in unmanipulated natural populations of the pipevine swallowtail butterfly, Battus philenor. In addition, search intensity and host selectivity differed among females whose egg loads were manipulated experimentally before they were released and followed in the field. Females with many eggs searched more intensely for hosts and were less selective when they encountered them.

“…Reproductive diapause is a clear feature of endemic Drosophila (Lumme and Lakovaara 1983), as it is for a number of other insects including the blowflies Phormia regina (Stoffolano 1974) and Protophormia terraenovae (Matsuo et al 1977), the monarch butterfly (Barker and Herman 1976), and many grasshoppers (Middlekauff 1964;Penner 1992). In the endemic Drosophila auraria group of the Japanese archipelago, autumnal adults enter diapause in response to short day length accompanied by cool temperature (Kimura 1988).…”

Some endemic Drosophila overwinter in a state of adult reproductive diapause where egg maturation is arrested in previtellogenic stages. When maintained at cool temperatures, adult Drosophila melanogaster enter reproductive dormancy, that is, diapause or diapause-like quiescence. The ability to survive for extended periods is a typical feature of diapause syndromes. In adults this somatic persistence may involve reduced or slowed senescence. Here we assess whether reproductively dormant D. melanogaster age at slow rates. Adults were exposed to dormancy-inducing conditions for 3, 6, or 9 wk. After this period, demographic parameters were measured under normal conditions and compared to the demography of newly eclosed cohorts. The age-specific mortality rates of postdormancy adults were essentially identical to the mortality rates of newly eclosed, young flies. Postdormancy reproduction, in contrast, declined with the duration of the treatment; somatic survival during dormancy may tradeoff with later reproduction. Adults in reproductive dormancy were highly resistant to heat and to oxidative stress. Suppressed synthesis of juvenile hormone is known to regulate reproductive diapause of many insects. Treatment of dormant D. melanogaster with a juvenile hormone analog restored vitellogenesis, suppressed stress resistance, and increased demographic senescence. We conclude that D. melanogaster age at slow rates as part of their reproductive dormancy syndrome; the data do not agree with an alternative hypothesis based on heat-dependent "rate of living." We suggest that low temperature reduces neuroendocrine function, which in turn slows senescence as a function of altered stress response, nutrient reallocation, and metabolism.
