| Abstract: | Various trapping methods and techniques developed for entomological studies are inefficient in attracting all arthropod groups. A new simple light trap, the basin light trap (BLT), to collect arthropod fauna around household in central Cameroon was thus designed. Its performance is evaluated by comparing collected data with those obtained by the Centre for Disease Control light trap (CDC) commonly used in mosquito studies. BLT were activated between 6 and 10 pm and CDC between 5 pm and 8 am. A total of 36,804 arthropods specimens were collected and sorted into 115 families within 20 orders and three phyla (Myriapoda, Arachnida and Hexapoda). BLT attracted more individuals (22,250 vs 14,554), families (106 vs 65) and significantly more families per night (33.0 ± 15.9 vs 21.0 ± 8.5) than CDC. Some families were collected by only one specific trap type while others overlapped between the two traps. Prosopistomatidae (Ephemeroptera) was the most abundant family collected by BLT. In contrast, Cecidomyiidae (Diptera) was the most abundant taxon trapped by CDC. These results indicate that collecting methods such as BLT complement available trapping methods in evaluating arthropod fauna in and around households. |
