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).

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.
Dengue and Dengue Hemorrhagic Fever.By Gubler, D.J.

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 (Stegomyia) albopictus (Skuse): a potential vector of Zika virus in Singapore.By Wong et al.

(Skuse): a potential vector of Zika virus in Singapore. PLoS Neglected Tropical Diseases 7(8): e2348.
BACKGROUND: Zika virus (ZIKV) is a little known arbovirus until it caused a major outbreak in the Pacific Island of Yap in 2007. Although the virus has a wide geographic distribution, most of the known vectors are sylvatic Aedes
mosquitoes from Africa where the virus was first isolated. Presently, Ae. aegypti
is the only known vector to transmit the virus outside the African continent, though Ae. albopictus
has long been a suspected vector. Currently, Ae. albopictus
has been shown capable of transmitting more than 20 arboviruses and its notoriety as an important vector came to light during the recent chikungunya pandemic. The vulnerability of Singapore to emerging infectious arboviruses has stimulated our interest to determine the competence of local Ae. albopictus
to transmit ZIKV.
