Aedes albopictus was found in M. Muzquiz, Coahuila, Mexico, in the summer of 1993. Aedes albopictus larvae were collected in tires and bottles at low density. Aedes aegypti, Toxorhynchites theobaldi, Culex quinquefasciatus, and Culiseta incidens were collected in the same containers.

Six mosquito species were identified in a survey of containers associated with 347 households in four villages in American Samoa. Aedes polynesiensis Marks (Diptera: Culicidae) and Aedes aegypti (L) were the most abundant species, representing 57% and 29% of the mosquitoes identified. Culex quinquefasciatus (Say), Culex annulirostris (Skuse), Aedes oceanicus (Belkin) and Toxorhynchites amboinen...

The 51.4-kDa-41.9-kDa binary toxin produced by different strains of Bacillus sphaericus shows differential activity toward Culex quinquefasciatus, Aedes atropalpus, and Aedes aegypti mosquito larvae. The patterns of larvicidal activity toward all three mosquito species and growth retardation in A. aegypti have been shown to be due to the 41.9-kDa protein. By using mutant toxins expressed in Esc...

A preliminary study on the vertical dispersal of Aedes populations in high-rise apartments was carried out in Presint 9, Putrajaya, Malaysia. Ovitraps were placed indoors within four blocks of high-rise apartments from the ground floors (0.0 - 3.0 m) until up to the tenth floors (28.1 - 30.0 m). Aedes aegypti was the dominant species found in the ovitraps (87.85%), while Aedes albopictus was fo...

BACKGROUND Dengue is amongst the most serious mosquito-borne infectious disease with hot spots in tropical and subtropical parts of the world. Unfortunately, no licensed vaccine for the disease is currently available in medicine markets. The only option available is the management of dengue vector mosquito, Aedes aegypti (Diptera: Culicidae). METHOD Predatory potential of five odonate nymphs ...

This study presents the first report of Aedes aegypti laying eggs on water surface an artificial breeding site in field. occurred city Rio de Janeiro inside a white bucket containing 11 liters rainwater. Conspecific larvae had previously been found this bucket. From 219 obtained, 135 (61.6%) were laid and 84 (38.3%) border Larvae (4th instar) adults obtained from identified as A. aegypti. behav...

Dengue occurs throughout the year in Hanoi, Vietnam, despite winter low temperatures <10°C. During July 2010 to March 2012, we surveyed monthly for Aedes larvae and pupae in 120 houses in 8 Hanoi districts. Aedes albopictus preferred discarded containers in summer and pupal density drastically decreased in winter. Aedes aegypti preferred concrete tanks and this preference increased in winter. E...

BACKGROUND & OBJECTIVES In 2000, a dengue outbreak occurred in Bangladesh that included Dhaka City. Both dengue vectors, Aedes aegypti and Ae. albopictus are present in Bangladesh. Aedes aegypti mosquitoes mainly breed in and around houses and Ae. albopictus is an outside breeder. There are many old trees throughout Dhaka City in different parks, streets and the university campus which may have...

OBJECTIVE To evaluate the efficacy of fish as predators of the Aedes aegypti larvae in laboratory conditions. METHODS The male and female of five different fish were included in the experiment. The tests to measure their consumption ability lasted five weeks for each species. Each trial involved four test tanks and four control tanks. Two control tanks contained just one fish, and the other t...

Methods employed by Australian quarantine officers to control Aedes mosquitoes in containers were tested against all stages of Aedes aegypti. Saltwater emersion killed all larvae but not pupae or eggs that were briefly exposed. Swimming pool chlorine, methyl bromide fumigation, and permethrin (2% active ingredient) spray provided 100% mortality of eggs, larvae, and pupae. Aerosol sprays incorpo...
