| a field cage test of the effects of the endosymbiont wolbachia on drosophila melanogaster. | wolbachia endosymbionts are known to affect the fitness of their hosts, but most of this information is from laboratory studies. in drosophila melanogaster, wolbachia frequencies vary clinically in frequency in australia and may confound climatic adaptation. here we use field cages in a reciprocal exchange design to test for wolbachia effects in d. melanogaster in winter at temperate and tropical sites. infected flies of both populations had a lower fecundity in tropical north queensland, whilst ... | 2001 | 11595053 |
| wolbachia pipientis in australian spiders. | wolbachia pipientis is an endosymbiotic bacterium common to arthropods and filarial nematodes. this study presents the first survey and characterization of wolbachia pipientis that infect spiders. all spiders were collected from queensland, australia during 2002-2003 and screened for wolbachia infection using pcr approaches. the wolbachia strains present in the spiders are diverse, paraphyletic, and for the most part closely related to strains that infect insects. we have also identified several ... | 2004 | 15386106 |

| a secure semi-field system for the study of aedes aegypti. | new contained semi-field cages are being developed and used to test novel vector control strategies of dengue and malaria vectors. we herein describe a new quarantine insectary level-2 (qic-2) laboratory and field cages (james cook university mosquito research facility semi-field system; mrf sfs) that are being used to measure the impact of the endosymbiont wolbachia pipientis on populations of aedes aegypti in cairns australia. | 2011 | 21445333 |
| Changes in the genetic structure of Aedes aegypti (Diptera: Culicidae) populations in Queensland, Australia, across two seasons: implications for potential mosquito releases. | Diseases transmitted by mosquitoes could be controlled if vector populations were replaced with strains that have reduced vector competency. Such a strategy is being developed for control of dengue virus which is transmitted by Aedes aegypti (L.) (Diptera: Culicidae). Mosquitoes artificially infected with the bacterium, Wolbachia pipientis Hertig, are being assessed as candidates for release at the adult stage with the aim of replacement of the wild population. Wolbachia can reduce the capacity ... | 2011 | 21936318 |

| Successful establishment of Wolbachia in Aedes populations to suppress dengue transmission. | Genetic manipulations of insect populations for pest control have been advocated for some time, but there are few cases where manipulated individuals have been released in the field and no cases where they have successfully invaded target populations. Population transformation using the intracellular bacterium Wolbachia is particularly attractive because this maternally-inherited agent provides a powerful mechanism to invade natural populations through cytoplasmic incompatibility. When Wolbachia ... | 2011 | 21866160 |
