The objective of this study was to evaluate the effectiveness of Aedes aegypti
mass trapping using the sticky trap
MosquiTRAP (MQT) by performing a cluster randomised controlled trial in Manaus, state of Amazonas, Brazil. After
an initial questionnaire and baseline monitoring of adult Ae. aegypti
abundance with BG-Sentinel (BGS) traps
in six clusters, three clusters were randomly assigned to the intervention arm where each participating household
received three MQTs for mass trapping during 17 months. The remaining three clusters (control arm) did not receive
traps. The effect of mass trapping on adult Ae. aegypti
abundance was monitored fortnightly with BGS traps. During
the last two months of the study, a serological survey was conducted. After the study, a second questionnaire was
applied in the intervention arm. Entomological monitoring indicated that MQT mass trapping did not reduce adult
abundance. The serological survey indicated that recent dengue infections were equally frequent in the
intervention and the control arm. Most participants responded positively to questions concerning user satisfaction.
According to the results, there is no evidence that mass trapping with MQTs can be used as a part of dengue control
programs. The use of this sticky trap is only recommendable for dengue vector monitoring.
