“…Despite the fact that carbon dioxide is an important attractive volatile for a number of species of Diptera (Berlyn, 1981;Ball & Luff, 1981 ;Warnes & Finlayson, 1985a,b), no significant responses to CO2 were recorded in either 3-day-old protein-deprived or 9-day-old gravid females in the present study. This supports the argument put forward by Eisemann (1988) that CO2 probably was not important for L. cuprina since orientation is generally highly specific to sheep and not to other non-ovine animals, unless contaminated with decomposing organic materials.…”

“…In the present study, the absence of L. sericata caught on sticky targets lacking an odour source further confirms the importance of olfaction in host or bait location by this species. It may be that responses to colour, which have been shown to affect L. sericata catch are only of importance at close range after initial activation and/or attraction has been achieved by olfactory cues, as has been suggested for other dipteran species (Berlyn, 1981).…”

“…Existing strikes are powerful attractants for blowflies, aliciting further multiple-oviposition (Mackerras & Mackerras, 1944). Carbon dioxide, eliminated in the breath of hosts is a powerful attractant for a number of species of haematophagous Diptera (Berlyn, 1981;Ball & Luff, 1981;Warnes & Finlayson, 1985a,b) and a possible role for CO2 as a stimulus for attraction and oviposition for L sericata has been suggested (Hobson, 1936;Cragg, 1956).…”

The nature of the responses of the sheep blowfly Lucilia sericata Meigen (Diptera: Calliphoridae) to carrion odours and carbon dioxide were examined in a windtunnel in the laboratory and the attractiveness of carrion‐bait was examined in the field. In the wind tunnel, gravid 9‐day‐old females increased both the number and duration of their flights, in response to carrion odours. In addition, linear velocity was reduced and the sinuosity of flight increased in the presence of these odours. With 3‐day‐old females, the response to carrrion odour depended on previous exposure to proteinaceous material. Protein deprived females showed kinetic responses to carrionodour which were similar to those of gravid females. No such changes were observed in protein‐fed females. No responses to CO2 were observed. In the field, the importance of olfactory cues in bait location was demonstrated by the absence of L. sericata from sticky targets lacking an odour bait. Increased bait concentration did not affect the age, sex ratio or ratio of L. sericata to other Lucilia spp. caught, but did increase the numbers caught. Analysis of the reproductive status of females caught, indicated that a greater number of gravid females were caught than expected, while a lower number of females in the final stages of vitellogenesis were caught than expected. The results show that the responses of L. sericata to odours are complex, and are dependent on both exogenous and endogenous stimuli, the latter including the stage of ovarian development.

The proposed development of a caravan park in Burley Wood was postponed in 1979 due to the presence of Hydrotaea irritans (Fall .) . This species causes intense irritation to man by feeding upon skin secretions and is also of veterinary importance. The fly population was monitored for 10 weeks using a number of trapping methods . The efficiency of one of these, the malaise trap, was found to be greatly increased by the controlled release of carbon dioxide . Used together with habitat modification and locally applied insecticides and repellants this is considered potentially valuable in ameliorating the problem . It is likely that the development of Rutland Water will increase the local range of the fly .

“…Investigations of the attractants that bring flies to the trap have shown that features associated with animals increase the numbers caught (Berlyn, 1978c;Ball & Luff, 1981). These authors have suggested that the artificial baits used with Manitoba traps could be employed as substitutes for animals in the development of repellent and topical insecticide formulations.…”

A comparison of the Diptera caught in Manitoba traps with those caught from cattle and other parts of the field ecosystem in northern England

Manitoba traps were used in a pasture field in northern England between June and October in 1980 and 1981. Samples of Diptera were also collected from cattle, cow dung, the field surface and from flowers in the hedges. A comparison of these samples, using multivariate similarity coefficients, showed that the Manitoba trap and cattle samples were most similar. There were 12 weeks in the two years during which both Manitoba trap and cattle samples were obtained, and the accumulated catches for this period were compared. They consisted mainly of cattle-visiting species, the proportion being greatest in the Manitoba trap samples (97%). Non-cattle-visiting species in the cattle sample (25%) consisted mainly of dung flies and species associated with the field surface. It is suggested that these were taken accidentally in proportion to their abundance around the cattle. There were some differences in the proportions of various species between the samples from cattle and the Manitoba trap, and the sex ratio of the three most abundant species was significantly higher in the traps. An experiment in which a large electrocuting grid was used to intercept flies travelling towards artificial bait as used in Manitoba traps, showed that the proportion of the two most abundant species differed significantly from a sample obtained from a nearby Manitoba trap. No such difference was observed in the sex ratios of these species.
