background: aedes aegypti mosquito is responsible for transmitting human diseases like dengue and chikungunya. personal or space protection with insect repellents is a practical approach to reducing human mosquito contact, thereby minimizing disease transmission. essential oils are natural volatile substances from plants used as protective measure against blood-sucking mosquitoes. methods: twen...

To investigate the effect of NaCl concentration on the survival of Aedes aegypti larvae, samples of Aedes aegypti larvae were collected from some discarded container, artificial pool from the urban area of Wahga town and exposed to 10%, 15% and 20% of NaCl concentration. The results of this study suggest that NaCl higher concentration can be used in a more human non-lethal chemical approach and...

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...

The repellent effect of Lantana camara flowers was evaluated against Aedes mosquitoes. Lantana flower extract in coconut oil provided 94.5% protection from Aedes albopictus and Ae. aegypti. The mean protection time was 1.9 h. One application of Lantana flower can provide more than 50% protection up to 4 h against the possible bites of Aedes mosquitoes. No adverse effects of the human volunteers...

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...

31 In early 2014, dengue cases were reported from the northern Mozambique, 30 years 32 since the last outbreak. We identified potential dengue vector species in three northern 33 towns, Pemba, Nampula and Nacala, and one southern town, Maputo, during the 34 outbreak in April 2014. A major dengue vector species, Aedes (Stegomyia) aegypti, 35 was found in all these towns. The dominant vector subs...

Insect larvae that live in temporary ponds must cope with a rapidly diminishing resource. We tested the hypothesis that floodwater mosquitoes would react to diminishing water levels by accelerating larval development time and emerging as smaller adults. Since a reduction in habitat size leads to increased larval densities, we also included two larval densities. Newly-hatched floodwater mosquito...

Aedes nummatus Edwards is redescribed and the adult habitus, female and male genitalia and larva are illustrated. Aedes pseudonummatus, new species, is described and the female habitus and genitalia are illustrated. These 2 species are placed in the subgenus Diceromyia Theobald, nuTfbrr&atuS being transferred from the subgenus Aedimorphus Theobald. A map shows the distribution of the above 2 sp...
