Abstract
Blood-engorged Culex nigripalpus (Theob.) collected throughout the year in two Florida localities were serologically tested to determine the host range of this mosquito in nature. A proportional increase in feeding on mammals occurred in early summer, reached a maximum between July and October, and was followed by a shift back to avian hosts which dominated the feeding pattern during winter and spring.

Effects of temperature and larval diet on development rates and survival of the dengue vector Aedes aegypti in north Queensland.

Abstract

W. Tun-Lin, T.R. Burkot and B.H. Kay. 2000. Effects of temperature and larval diet on development rates and survival of the dengue vector Aedes aegypti in north Queensland, Australia. Medical and Veterinary Entomology 14(1): 31–37.

Immature development times, survival rates and adult size (wing-lengths) of the mosquito Aedes aegypti (L.) (Diptera: Culicidae) were studied in the laboratory at temperatures of 10–40°C. The duration of development from egg eclosion (hatching of the first instar) to adult was inversely related to temperature, ranging from 7.2 ± 0.2 days at 35°C to 39.7 ± 2.3 days at 15°C. The minimum temperature threshold for development (t) was determined as 8.3 ± 3.6°C and the thermal constant (K) was 181.2 ± 36.1 day-degrees above the threshold. Maximum survival rates of 88–93% were obtained between 20 and 30°C. Wing-length was inversely related to temperature. The sex ratio (♀:♂) was 1 : 1 at all temperatures tested (15, 20, 25 and 35°C) except 30°C (4 : 3).

This study was conducted to determine the effects of increased water temperatures on the development of Aedes aegypti immatures under laboratory conditions in Trinidad, West Indies using temperature regulated water baths to cover a range of temperatures from 24–25◦C to 34–35◦C at a relative humidity of 80%.

THE outbreaks of dengue in the Caribbean area in 1963–64 and 1968–691 have served as reminders of the continuing presence of dengue in the Western Hemisphere, and the threat of recurrence of epidemic dengue in the southern United States.

Abstract
Dengue fever, a very old disease, has reemerged in the past 20 years with an expanded geographic distribution of both the viruses and the mosquito vectors, increased epidemic activity, the development of hyperendemicity (the cocirculation of multiple serotypes), and the emergence of dengue hemorrhagic fever in new geographic regions. In 1998 this mosquito-borne disease is the most important tropical infectious disease after malaria, with an estimated 100 million cases of dengue fever, 500,000 cases of dengue hemorrhagic fever, and 25,000 deaths annually. The reasons for this resurgence and emergence of dengue hemorrhagic fever in the waning years of the 20th century are complex and not fully understood, but demographic, societal, and public health infrastructure changes in the past 30 years have contributed greatly.

Aedes aegypti in a Texas coastal county as an index of dengue fever receptivity and control.

Abstract
Since Galveston County, Texas, is one of the high risk areas for the reintroduction of dengue, we have maintained an Aedes aegypti surveillance program since 1977 by using ovitraps to determine the density and distribution of this species in 17 communities. A. aegypti adults were present primarily from May through November...

Zika Virus in Gabon (Central Africa) – 2007: A New Threat from Aedes albopictus?

Grard et al. 2014. Zika Virus in Gabon (Central Africa) – 2007: A New Threat from Aedes albopictus? PLoS Neglected Tropical Diseases 8(2): e2681.

Background

Chikungunya and dengue viruses emerged in Gabon in 2007, with large outbreaks primarily affecting the capital Libreville and several northern towns. Both viruses subsequently spread to the south-east of the country, with new outbreaks occurring in 2010. The mosquito species Aedes albopictus, that was known as a secondary vector for both viruses, recently invaded the country and was the primary vector involved in the Gabonese outbreaks. We conducted a retrospective study of human sera and mosquitoes collected in Gabon from 2007 to 2010, in order to identify other circulating arboviruses.
