“…The mixing process during winter was facilitated by warming up the marked ßies; and 2) A decreased survival of caged stable ßies labeled with ßuorescent dusts was reported by LaBrecque et al (1975) and Williams et al (1977): In contrast, no effect was found in horn ßies (Haematobia irritans L.) and Drosophila simulans (Sturtevant) (Moth and Barker 1975, Chamberlain et al 1977, Hogsette 1983. In general, our handling of ßies resulted in relatively low mortality rates (4.4% Ϯ12.5 (SE) for the orange and 4.5% Ϯ 12.5 (SE) for the blue dust).…”

A population of stable flies, Stomoxys calcitrans (L.), was studied on a Danish cattle farm in two successive years. Flies were captured monthly by sweep nettings and marked with fluorescent dust. Absolute population size, dilution rate, loss rate, and adult longevity were estimated by means of a modified version of Bailey's triple catch method. In both years, the abundance of flies peaked in July. Using a statistical model, we were able to explain 86.6% of the variation in the per capita growth rate r as a function of current temperature, precipitation, and population size. Omitting precipitation from the model, it still explained 69.3%. The model predicts that stable flies have a temperature optimum at 21.8°C, and that no development will take place when temperatures inside the stable are below 10.2°C or above 33.5°C. At the optimal temperature the intrinsic rate of natural increase is 0.070 d(-1). The per capita dilution rate increased with temperature and decreased with population size, whereas no effect of these factors on the per capita loss rate could be shown. Mean adult survival time was estimated to 6.3 d with 95% CL ranging from 4.3 to 11.1 d. The study points at the possibility of developing predictive models as tools for achieving better, and more environmentally sound, control of stable flies.

“…Marks are permanent and are recorded correctly Crumpacker (1974) and Moth & Barker (1975) report laboratory experiments in which flies remained marked and multiple marks were distinguishable for 11 and 28 days, respectively. Shorrocks & Nigro (1981) tested retention of marks in outdoor cages in a blind experiment and found lOOyo retention after three days and 80% retention after 10 days.…”

Adult survival rates were estimated in field populations of domestic Drosophila species by means of multiple capture-recapture experiments. Micronized fluorescent dusts were used as marking agents and analysis used the Fisher-Ford model: the assumptions of this model are justified using evidence from this study and the literature. Survival rates were commonly 0.45-0.85 per day, suggesting that mean life expectancy for adult flies is from 1.3 to 6.2 days in natural populations. No consistent differences in survival between sexes or seasons were demonstrated. The implications of low natural survival rates are discussed.

“…Just before the release, groups of 100 flies (two vials each with 50 flies) were transferred into vials with 0.0015 (G0.0005) g of fluorescent micronized dust (Radiant) and lightly shaken according to the recommendations in Moth & Barker (1975). Dust colours were randomly assigned to the different lines, and changed between releases.…”

Can artificially selected phenotypes influence a component of field fitness? Thermal selection and fly performance under thermal extremes

Artificially selected lines are widely used to investigate the genetic basis of quantitative traits and make inferences about evolutionary trajectories. Yet, the relevance of selected traits to field fitness is rarely tested. Here, we assess the relevance of thermal stress resistance artificially selected in the laboratory to one component of field fitness by investigating the likelihood of adult Drosophila melanogaster reaching food bait under different temperatures. Lines resistant to heat reached the bait more often than controls under hot and cold conditions, but less often at intermediate temperatures, suggesting a fitness cost of increased heat resistance but not at temperature extremes. Cold-resistant lines were more common at baits than controls under cold as well as hot field conditions, and there was no cost at intermediate temperatures. One of the replicate heat-resistant lines was caught less often than the others under hot conditions. Direct and correlated patterns of responses in laboratory tests did not fully predict the low performance of the heat selected lines at intermediate temperatures, nor the high performance of the cold selected lines under hot conditions. Therefore, lines selected artificially not only behaved partly as expected based on laboratory assays but also evolved patterns only evident in the field releases.
