Factors Influencing the Outcome of Mark-Release-Recapture Studies with <I>Culex tarsalis</I> (Diptera: Culicidae)

Abstract

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 traps operated outside the study area (foreign) or reared from field-collected immatures (reared). These results supported published studies on Anopheles and Ochlerotatus that indicated mosquitoes may "memorize" flight paths within their environment. Releasing gravid females provided a potentially useful replacement for reared females, because these gravids oviposited at wetlands and then dispersed to upland traps. Releasing local, foreign, or reared mosquitoes just after sunrise or just before sunset did not alter recapture success or the distance dispersed. Elevated wind speeds inhibited dispersal from protected microhabitats with citrus orchards and resulted in most recaptures being found at the leeward portion of the orchard.

Memória espacial e/ou olfativa em flebotomíneos em área endêmica de leishmaniose tegumentar americana, sul do Brasil

“…O número de flebotomíneos recapturados foi maior na segunda do que na primeira noite, provavelmente porque nesta ventava fortemente. Reisen e cols 24 constataram que o vento foi um fator negativo na dispersão de Culex tarsalis. O aumento substancial do número de fêmeas recapturadas no quinto dia após a soltura pode estar relacionado com o retorno das mesmas, à procura de um novo repasto sanguíneo, após realizarem a oviposição.…”

“…Culex quinquefasciatus is a cosmopolitan mosquito with worldwide distribution, especially in the tropical and subtropical areas and is associated with human dwellings (David et al 2012). Culex quinquefasciatus, the southern house mosquito, has been relatively well studied in recent years, probably because of its role in the transmission of important human diseases such as urban lymphatic filariasis, Saint Louis encephalitis virus, and Western equine encephalitis virus (Reisen et al 2003;Jones et al 2012).…”

“…quinquefasciatus, the southern house mosquito, has been relatively well studied in recent years probably because of its role in the transmission of important human diseases such as urban lymphatic filariasis, Saint Louis encephalitis virus (SLEV), and Western equine encephalitis virus [2,3]. In the West Africa subregion, Culex mosquitoes are not filariasis vectors yet.…”
