Evaluation of oviposition traps as an entomological surveillance method for Aedes aegypti (Diptera, Culicidae)

Abstract

ABSTRACT. Evaluation of oviposition traps as an entomological surveillance method for Aedes aegypti (Diptera, Culicidae). This study aimed to describe the behavior of oviposition traps for Aedes aegypti over time, to compare it with the larval survey and to investigate the association with climatic variables. It was conducted in São José do Rio Preto city, São Paulo. Daily climatic data and fortnightly measurements for oviposition traps and larval infestation were collected from October 2003 to September 2004. Three different periods were identified in the behavior of oviposition traps' positivity and mean number of eggs: increase, plateau and decrease in values. These measurements followed the variation of climatic data from the first and third periods. High correlation was obtained between the positivity and the mean number of eggs. The oviposition traps showed higher capacity to detect the vector than did larval survey. It was observed that the first (October to December) and third (May to September) periods were considered to be the most suitable to use oviposition traps than larval surveys.

Using adult Aedes aegypti females to predict areas at risk for dengue transmission: A spatial case-control study

“…The most commonly used methods for entomological surveillance of Ae. aegypti are based only in mosquito larvae (Barbosa et al, 2010;Wijayanti et al, 2016). On the other hand, NAF is based on adult females, presents a superior performance and a lower operational cost.…”

“…Comparatively, NAF demanded 71,5% less human resources to be constructed when compared to BI. Barbosa et al (2010) suggested that eggs from oviposition traps could be used as an index to determine areas with higher risks for epidemics. However, the authors also suggested that this methodology is more adequate for situations in which there is substantial mosquito production.…”

Surveillance, insecticide resistance and control of an invasive Aedes aegypti (Diptera: Culicidae) population in California

“…aegypti surveillance and control, CMAD selected four traps from the wide variety available. These included: (i) the CO 2 - baited EVS trap ( Rohe & Fall, 1979 ), (ii) oviposition cups ( Barbosa et al , 2010 ; Furlow & Young, 1970 ), (iii) CO 2 - baited BG Sentinel (BGS) trap ( www.bg-sentinel.com - without octenol attractant) and (iv) Autocidal Gravid Oviposition trap (AGO-B) ( MacKay et al , 2013 ). The decision to use CO 2 with the BGS was based on a study by de Ázara et al (2013) that showed that more females were collected in BGS baited with CO 2 than without.…”
