The Naval Medical Research Unit-3 (NAMRU-3), Cairo, Egypt, has conducted Field and Laboratory trainings for the NAVRC Entomologists. This is part of the ongoing study of Risk Mapping of Arbovirus Transmission in Nigeria NAMRU-3, is carrying out in partnership with NAVRC.
Three Communities each from three Senatonatorial Zones in Enugu State were randomly selected. The selected communities are Agbalenyi in oji-River, Opi in Nsukka and Ugbawka in Nkanu East. The Study involves setting of traps for capturing and identifying Mosquito species in the selected communities.
FIELD STUDIES:
The Entomologists were trained on Mosquito trappings during which specimens were collected for over 7 consecutive nights, at each of the four selected field sites. At each site, three Biogents-Sentinel (BGS) traps baited with lure were placed in the morning (between 06:00 and 10:00) and collected at dusk (between 16:00 and 20:00).
Upon the collection of the BGS traps, three CDC UV trap baited with CO2 (produced by yeast and sugar fermentation) and lure were set and collected the following morning (between 06:00 and10:00) and a new set of three BGS traps were deployed. All coordinates for trapping sites were recorded on a handheld GPS.
LABORATORY STUDIES:
The laboratory component involved sorting and microscopic morphological identification of all mosquitoes collected during the study and preservation in RNA later.
Summary of the Collections
A total of two thousand five hundred and ninety-eight (2598) mosquitoes were collected during the first phase of the study: One thousand and ninety (1090) from Opi; Six hundred and eighty six (686) from 82 Div.; Three hundred and thirty one (331) from Ugbawka and four hundred and ninety one (491) from Agbalenyi.
CDC UV Light Traps has the highest mosquitoes collection of 2160 while BGS traps has the least collection of 203. Collection made using modified human landing catch was 235 mosquitoes. The Study is a year-long exercise .
