An empirical model of flight initiation coupled with data from a longitudinal study predicted that the flight dispersal of Triatoma infestans from peridomestic sites was more likely to occur in late summer. To partially test this prediction, we operated 11-12 black light traps from 1945 to 2200 hours in March 2003 in two villages in northern Argentina. All peridomestic sites around the light tr...

Male South Indian gerbils (T. indica cuvieri), both adults and weanlings, were olfactory bulbectomized (OBX) and changes in male reproductive behaviour were assessed. Consequent to OBX, majority of the adult males failed to ejaculate, and courtship behaviour has also been considerably reduced. All OBX weanlings were rendered incapable of ejaculation. However, maturational parameters, and organ ...

Biting midges of the genus Culicoides (Diptera: Ceratopogonidae) were collected during the summer of 2007 at the Greenville and Riverbanks Zoos in South Carolina with Centers for Disease Control and Prevention (CDC) traps equipped with ultraviolet or incandescent lights and baited with carbon dioxide. Sixteen species of Culicoides were collected, four of which represented more than 80%. They we...

Trapping success, abundance, parity rate, and body size indices of Culex pipiens (L.) and Culex restuans Theobald, important vectors of West Nile virus (family Flaviviridae, genus Flavivirus, WNV), were determined for specimens captured from both ground level (approximately 1-m) and elevated (approximately 6- to 7-m) CO2-baited CDC miniature light traps. Mosquitoes were collected from six study...

Three potentially important aspects of mark-release-recapture experimentation were addressed: 1) source of mosquitoes for release, 2) time of release, and 3) weather during recapture. Culex tarsalis Coquillett mosquitoes collected as adult host-seeking females from dry ice-baited traps (CO2 traps) operated within the study area (local) were recaptured more frequently than females collected from...

BACKGROUND Baited traps are potential tools for removal or surveillance of disease vectors. To optimize the use of counter-flow traps baited with human odor (nylon socks that had been worn for a single day) to capture wild mosquitoes in the Gambia, investigations were conducted at a field experimental site. METHODOLOGY/PRINCIPAL FINDINGS Experiments employing Latin square design were conducte...

a survey on the genus exallonyx kieffer, 1904 (hymenoptera: proctotrupidae) was conducted in northern iran. the specimens were collected using malaise traps during 2010–2011. the genus exallonyx and six species were collected and identified for the first time from iran: exallonyx ater (gravenhorst, 1807), e. brevicornis (haliday, 1839), e. formicarius kieffer, 1904, e. ligatus (nees, 1834), e. ...

Spatial and temporal relationships among catches of adult stable flies, Stomoxys calcitrans (L.), on sticky traps in eastern Nebraska were evaluated. Twenty-five alsynite sticky traps were placed in a 5 by 5 grid with ≍1.6-km intervals in a mixed agricultural environment from 2003 to 2011. Denser grids of 45-90 traps were implemented for varying lengths of time during the course of the study. M...
