“…The character that they measured was the ability of the flies to distinguish between long and short days. They concluded that the longer critical daylength, a 'northern' character, was incompletely dominant to the shorter one (Lumme, 1978). In a later paper, Lumme (1981) described a gene for this critical Researchers examining the genetics of diapause in other insects have found a polygenic basis of inheritance (see reviews in Beck, 1980 andDanks, 1987).…”

“…Diapause has been investigated for many Drosophilids [for example, Drosophila robusta (Carson & Stalker, 1948;Levitan, 1951), Drosophila littoralis (Lumme et at., 1974;Lumme & Oikarinen, 1977;Lumme, 1978), Drosophila deflexa Duda (Basden, 1952(Basden, , 1954a, Drosophila subobscura (Basden, 1954b), Drosophila auraria complex (Kimura, 1984), D. melanogaster (Saunders et al, 1989;Izquierdo, 1991), also see review by Lumme & Lakovaara, 1983]. However, the genetic resources available for the study of this phenomenon in species other than D. metanogaster are limited.…”

Female Drosophila melanogaster exhibit ovarian diapause at low temperatures and short day lengths. We found that D. melanogaster isofemale lines from Windsor (Ontario, Canada) had a significantly higher percentage of females in diapause than did those from Cartersville (Georgia, U.S.A.). To investigate the heredity of this trait, we performed a 16-reciprocal cross analysis using two extreme isofemale lines called W and C. We found that diapause in D. melanogaster is inherited as a simple autosomal recessive trait with the C response (less flies in diapause) completely dominant to the W one. Maternal and cytoplasmic factors did not affect differences in diapause in these lines. The result of our genetic analysis of diapause in D. melanogaster opens many avenues for the genetic dissection of this ecologically relevant trait.

“…This species has a circumpolar distribution range (Throckmorton, 1982) and faces a 6-month-long unfavorable winter season in the northern parts of its distribution. Females overwinter in photoperiodically controlled reproductive diapause during which the development of their ovaries is halted in the pre-vitellogenic stage (Lumme, 1978;Watabe, 1983). We maintained female and male flies originated from a northern Finland (66°N) population in gradually changing ambient temperature and photoperiod conditions mimicking the conditions from autumn through spring in their location of origin.…”

SUMMARYCoping with seasonal changes in temperature is an important factor underlying the ability of insects to survive over the harsh winter conditions in the northern temperate zone, and only a few drosophilids have been able to colonize sub-polar habitats. Information on their winter physiology is needed as it may shed light on the adaptive mechanisms of overwintering when compared with abundant data on the thermal physiology of more southern species, such as Drosophila melanogaster. Here we report the first seasonal metabolite analysis in a Drosophila species. We traced changes in the cold tolerance and metabolomic profiles in adult Drosophila montana flies that were exposed to thermoperiods and photoperiods similar to changes in environmental conditions of their natural habitat in northern Finland. The cold tolerance of diapausing flies increased noticeably towards the onset of winter; their chill coma recovery times showed a seasonal minimum between late autumn and early spring, whereas their survival after cold exposure remained high until late spring. The flies had already moderately accumulated glucose, trehalose and proline in autumn, but the single largest change occurred in myo-inositol concentrations. This increased up to 400-fold during the winter and peaked at 147nmolmg -1 fresh mass, which is among the largest reported accumulations of this compound in insects.

“…Recent studies have shown that the trait displays considerable environmental and genetic variance (d. papers in Dingle, 1978a). Environmentally diapause is frequently a function of a temperature-photoperiod interactions, and genetically it often displays high proportions of additive genetic variance (Dingle et al, 1977), although Mendelian segregation of diapause from nondiapause with dominant gene action has been reported from several species (Tauber and Tauber, 1977;Lumme, 1978;Vepsalainen, 1978).…”
