Studies were conducted to determine the selection of humans, chickens and rabbits by Culicidae in three different environments in the province of Chaco, Argentina. Mosquitoes were collected fortnightly using cylindrical metal traps containing animal bait (chickens and rabbits). The mosquitoes were collected between June 2001-May 2002. During the same period and with the same frequency, mosquito...

OBJECTIVE To identify the parity status of Ochlerotatus scapularis females in laboratory and field conditions. METHODS Field collections were carried out fortnightly using a hand-held aspirator in Vale do Ribeira, Southeastern Brazil, from April 2003 to March 2004. In laboratory, 100 Ochlerotatus scapularis F1 females were obtained and followed up individually, reporting the number of blood m...

Coetzeemyia, a new subgenus of Aedes Meigen (in the broad traditional sense, pre-Reinert 2000), is characterized and diagnosed. Aedes fryeri (Theobald) is removed from the subgenus Levua Stone and Bohart (genus Levua of Reinert et al. 2004) and placed in the new monotypic subgenus Coetzeemyia as its type species by present designation. Recognition of Coetzeemyia is based in part on a cladistic ...

Ochlerotatus japonicus larvae were collected from natural rockpools in New Jersey within the Delaware Water Gap National Recreational Area. Previously reported collections of Oc. japonicus in the United States have been limited to artificial containers and an occasional treehole.

The species composition and seasonal population dynamics of mosquitoes trapped in the Belek Region of Turkey are described. Eight traps (four New Jersey light traps and four CO2 baited traps) were activated weekly at four different sampling sites (wooded area, open field, village, and road edge). Between May and December, 1997, 4,542 specimens representing seven species (Culex pipiens, Culex tr...

From 971 larvae reared from the oviposition traps, 5 species were identified: Ochlerotatus triseriatus (45%), Oc. j. japonicus (43%), Aedes albopictus (7%), Culex...

Predatory efficiency of Diplonychus rusticus (Fabricius) was recorded at different prey density with different salinity ranges. When the salinity level (ppt) was increased, the predation rate of the bug decreased. Fifth nymphal stage showed higher predation in the 2, 4 and 6 ppt levels of salinityin both 1 hr and 24 hr period of exposure at prey densities 50, 100, 150 and 200. At prey density 1...
