Urbanization and its effects on the ecology of mosquitoes in Macau, Southeast Asia.

Recent urbanization in Macau has resulted in the precipitous decline to zero in populations of several anopheline vectors of malaria while providing optimal habitat for the population increase in culicines. Of 18 species of mosquitoes reported in Macau in recent years, 15 species are included here. Culex quinquefasciatus, Culex sitiens, and Aedes albopictus were the most abundant species. Notes are provided for Anopheles sinensis, Armigeres magnus, Armigeres subalbatus, Culex foliatus, Culex fuscanus, Culex infantulus, Culex rubithoracis, Culex sumatranus, Culex tritaeniorhynchus, Mansonia uniformis, Toxorhynchites splendens, and Tripteroides sp.

Mosquito surveillance employing New Jersey light traps on Indian reservations in Iowa, Nebraska and South Dakota in 1984 and 1985.

A mosquito surveillance program was established in 1983 on Indian reservations in Iowa, Nebraska and South Dakota. Standard New Jersey light traps were operated on 12 reservations throughout the summer seasons in 1984 and 1985. Rainfall levels in general were higher than normal at all sites in 1984 but were lower than normal at most sites in 1985. Aedes vexans was the most abundant species collected on all reservations and Culex tarsalis second in abundance. Man-biting collections of mosquitoes near Brookings in 1984 reached 35 mosquitoes/5 minutes in early July and were largely composed of Ae. vexans, Ae. dorsalis and Ae. nigromaculis while numbers of Cx. tarsalis and An. quadrimaculatus were minor. During the same period in 1985, man biting collections averaged less than 5/5 minutes.

Occurrence and seasonal incidence of mosquitoes on Indian reservations in Iowa, Nebraska and South Dakota during 1983.

A mosquito surveillance program designed to prevent future human cases of Western equine encephalitis or Saint Louis encephalitis was established in 1983 on Indian reservations under the jurisdiction of the Aberdeen Area Indian Health Service in Iowa, Nebraska and South Dakota. Standard New Jersey light traps were operated on all reservations throughout the summer season while CDC miniature and encephalitis virus surveillance traps were employed for shorter periods of time on 4 reservations. Aedes vexans was the most abundant species except on the Pine Ridge, Rosebud, Winnebago and Yankton Sioux reservations in which Culex tarsalis predominated and for the Sac-n-Fox where Aedes trivittatus occurred with the greatest frequency.

First record of genus Coelomomyces in Macau (China): Coelomomyces stegomyiae var. stegomyiae parasitizing Aedes albopictus.

During a mosquito survey carried out in 1994-95, in Macau, southern China, Coelomomyces stegomyiae var. stegomyiae was found parasitizing Aedes albopictus. This constitutes the first record of this genus as potential agents of mosquito control in the area.

On Coquilleitidia crassipes, a new record for Macau, with a key to adults of the subgenera and species groups of the genus.

Coquillettidia (Coquillettidia) crassipes is recorded for the 1st time in the Territory of Macau, southern China. The systematics of the genus is examined, new species groups are proposed, and a key to subgenera and species groups of Coquillettidia is provided.
