| pest fruit fly (diptera: tephritidae) in northwestern australia: one species or two? | since 1985, a new and serious fruit fly pest has been reported in northwestern australia. it has been unclear whether this pest was the supposedly benign endemic species, bactrocera aquilonis, or a recent introduction of the morphologically near-identical queensland fruit fly, b. tryoni. b. tryoni is a major pest throughout eastern australia but is isolated from the northwest region by an arid zone. in the present study, we sought to clarify the species status of these new pests using an extensi ... | 2010 | 19602297 |
| close genetic similarity between two sympatric species of tephritid fruit fly reproductively isolated by mating time. | two sibling species of tephritid fruit fly, bactrocera tryoni and b. neohumeralis, occur sympatrically throughout the range of b. neohumeralis in australia. isolation between the two species appears to be maintained by a difference in mating time: b. tryoni mates at dusk, whereas b. neohumeralis mates during the middle of the day. a morphological difference in humeral callus color also distinguishes the two species. despite clear phenotypic evidence that b. tryoni and b. neohumeralis are distinc ... | 2000 | 10937263 |
