The results of progeny tests of males and females captured during two field trials of sex-linked translocation strains for genetic control of L. cuprina are presented. Males released as mature larvae survived to adulthood and mated with field females. However, the levels of genetic death introduced into the population were insufficient to suppress the native population. This was due partly to seasonal ineffectiveness of the release method, and partly to poor performance of the released males. On average, the mating competitiveness of the released males was only one-third that of field males, whereas their field-reared, translocation-bearing sons were fully competitive with native males.

AbstractA method for releasing genetically altered strains of Lucilia cuprina (Wied.) as free-falling larvae from aircraft was tested. Full-fed genetically marked third-instar larvae were released from aircraft flying at a height of 150 m and speeds of 120 or 220 km/h. Progeny tests of adult flies trapped subsequently indicated that released male larvae survived to the adult stage and were competitive with wild males for females.

AbstractCompetitiveness of laboratory-reared Lucilia cuprina (Wied.) has been examined under field conditions. The separate release of males and females each marked genetically and with fluorescent dust permitted estimates of dispersal, survival and mating competitiveness for both sexes. The ability of males to seek mates and introduce marker genes into a field population did not appear to be impaired as a result of several years of laboratory colonization. Released females were readily inseminated though suitable conditions did not exist for adequate assessment of their ability to produce offspring.

Daily catches of the Australian sheep blowfly, Lucilia cuprina, in Western Australian blowfly traps were not significantly affected by exposing the baits in traps for up to 3 days in the field before trapping. Exposure of the baits for longer periods significantly increased the daily catch totals of both sexes. Baits with a mean exposure time before trapping of 7 days (old baits) returned significantly higher catches than baits with a zero exposure time (fresh baits): 5-fold and 3-fold increases, respectively, for males and females. Exposure of baits for only 1 day was sufficient to produce significant changes in the reproductive age composition of female catches; proportions of newly emerged females increased and proportions of gravid females decreased. Coefficients of variation for old bait/new bait catch ratios were small, 16.4% for males and 12.3% for females, which confirmed that both baits exhibited consistent levels of attractiveness on different trapping dates. Procedures are suggested for estimating population densities of L. cuprina based on trap catches using fresh and old baits.

Field trials were conducted with translocation/eye colour (TE) strains of L. cuprina to measure the mating ability of the males under field conditions and assess their potential for suppressing sheep blowfly populations. Rates of increase in L. cuprina were highest in spring (3' 6-9' 1 per generation), consistently low during summer (0'1-0'6 per generation) and somewhat higher during autumn (1'1-3'4 per generation). The TE strains released had the potential to prevent population increases of this magnitude. Their failure to do so during these trials resulted from their low mating competitiveness (0' 33) relative to that of field-reared males (1 . 0), inadequacy of the larval release method and the limited capacity of the experimental mass-rearing facility.
