Australian Distribution of 17 Species of Fruit Flies (Diptera: Tephritidae) Caught in Cue Lure Traps in February 1994

Abstract

We report the first widespread survey of tephritid fruit flies attempted in a single time period. 1,471 cue lure traps caught 17 species, and extensions to previously recorded geographical ranges were detected for seven of them: Bactrocera tryoni, B. neohumerulis, B. frauenfeldi, B. aeroginosu, Dacus absonifascies, D. aequalis and D. newmani. The traps also unexpectedly caught several B. cacuminatu and also both males and females of Dirioxupornia and Cerutitis capitata. The geographical variation in the relative abundance of B. tryoni and B. neohumeralis in the regjon of their co-occurrence was in substantial agreement with earlier estimates. The regional variation in abundance of B. tryoni in the eastern states was in accordance with the predictions of a published bioclimatic model. Furthermore, the spread of this species (expected from the model) to several locations in the Northern Territory is recorded here for the first time.

Tropical tephritid fruit fly community with high incidence of shared Wolbachia strains as platform for horizontal transmission of endosymbionts

“…Specimens were collected in tropical far north Queensland during summer, except for uninfected control individuals of B. cacuminata , B. neohumeralis , B. tryoni , D. aequalis and D. newmani from southeast Queensland, New South Wales and the Northern Territory (http://onlinelibrary.wiley.com/doi/10.1111/1462-2920.12382/suppinfo). Flies were collected by using traps equipped with male attractant cue lure (Osborne et al ., ; Royer and Hancock, ), except for adults of B. cacuminata that were collected from infested wild tobacco fruits in Richmond, New South Wales. Besides adult fruit fly individuals, we included 10 B. cacuminata larvae collected from wild tobacco fruits in Atherton, Queensland (Table ), 7 parasitoid wasps that had emerged from pupated B. cacuminata of the same population in Queensland, and 17 wasp parasitoids collected from an orange orchard in Richmond, New South Wales (Table ).…”

The likely fate of hybrids of Bactrocera tryoni and Bactrocera neohumeralis

“…The species are sympatric, with the geographic distribution of B. neohumeralis being wholly contained within the greater one of B. tryoni (Birch and Vogt, 1970;Drew, 1978;Osborne et al, 1997). Biologists have paid much attention to the species because, despite their propensity to produce viable, fertile hybrids in the laboratory, they maintain their integrity in the field.…”

The genome of the Queensland fruit flyBactrocera tryonicontains multiple representatives of themarinerfamily of transposable elements

“…The Queensland fruit fly, Bactrocera tryoni , is endemic to Eastern Australia where it has become a serious pest of fruit and vegetable crops (Drew et al. , 1982; Drew, 1989; Osborne et al. , 1997), with the capacity for further spread, both within and outside Australia.…”
