The global re-emergence of chikungunya virus (CHIKV) over the last decade presents a serious public health risk to Australia. An increasing number of imported cases further underline the potential for local transmission to occur if local mosquitoes bite an infected traveller. Laboratory experiments have identified a number of competent Australian mosquito species, including the primary vectors ...

Thirteen strains among 3 species of entomopathogenic bacteria were tested against 3 medically important mosquito species in French Polynesia. Two strains of Bacillus thuringiensis were highly toxic to Aedes polynesiensis, Aedes aegypti, and Culex quinquefasciatus. Six of 7 strains of Bacillus sphaericus tested were highly toxic to Cx. quinquefasciatus but not to the Aedes spp. Clostridium bifer...

Mosquitoes collected in Germany in 2016, including Culex pipiens pipiens biotype pipiens, Culex torrentium and Aedes albopictus, as well as Culex pipiens pipiens biotype molestus (in colony since 2011) were experimentally infected with Zika virus (ZIKV) at 18 °C or 27 °C. None of the Culex taxa showed vector competence for ZIKV. In contrast, Aedes albopictus were susceptible for ZIKV but only a...

During 1992, ovitrapping to sample populations of container-breeding Aedes was conducted at 28 U.S. Air Force installations in North America. Aedes albopictus was collected at 19 installations. The collections of Ae. albopictus at Goodfellow Air Force base (AFB), TX, and Moody AFB, GA, represent new records for Tom Green and Lowndes counties, respectively. Six installations were positive for Ae...

The dynamics of heterospecific and conspecific mating between Florida strains of Aedes aegypti and Aedes albopictus was examined. In nonchoice experiments where conspecific males were not available, dissection of the spermathecae showed that heterospecific insemination was an infrequent event for both species combinations (10.6% for Ae. albopictus with Ae. aegypti males, 3.6% for the reciprocal...

BACKGROUND Aedes aegypti and Aedes albopictus perform an important role in the transmission of the dengue virus to human populations, particularly in the tropical and subtropical regions of the world. Despite a lack of understanding in relation to the maintenance of the dengue virus in nature during interepidemic periods, the vertical transmission of the dengue virus in populations of A. aegypt...

BACKGROUND Aedes-borne diseases as dengue, zika, chikungunya and yellow fever are an emerging problem worldwide, being transmitted by Aedes aegypti and Aedes albopictus. Lack of up to date information about the distribution of Aedes species hampers surveillance and control. Global databases have been compiled but these did not capture data in the WHO Eastern Mediterranean Region (EMR), and any ...

Larval survey was carried out in 6 localities in the urban areas (Putrajaya) and suburban areas (Kuala Selangor) from January until December 2010. A total of 520 representative households in 6 localities were selected. Breeding habitats were sampled outdoors in the surroundings of housing areas. The study indicated that the most predominant species found in both areas was Aedes albopictus with ...

The first part of this project include the surveillance of dengue vectors, ovitrap collection, and source reduction in southern Taiwan. In addition to Kaoshung, Pingtung and Tainan counties, none Aedes aegypti (AE) vector was found in the areas around 30km of tropic cancer at west southern of Taiwan. Meanwhile AE can only be found in 3 Li of Taitung city and 3 Li in MaKo city of Pescadores. Low...
