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 Ae. aegypti 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.
本研究的目的是通过在巴西亚马孙州玛瑙斯市开展一项整群随机对照试验，评估使用粘性诱捕器MosquiTRAP（MQT）进行埃及伊蚊大规模诱捕的效果。在对六个整群中的成年埃及伊蚊丰度进行初步问卷调查和基线监测后，使用BG-哨兵（BGS）诱捕器，随机将三个整群分配到干预组，在此期间，每个参与家庭在17个月内收到三个MQT用于大规模诱捕。其余三个整群（对照组）未收到诱捕器。每两周用BGS诱捕器监测大规模诱捕对成年埃及伊蚊丰度的影响。在研究的最后两个月，进行了血清学调查。研究结束后，在干预组进行了第二次问卷调查。昆虫学监测表明，MQT大规模诱捕并未降低成年埃及伊蚊的丰度。血清学调查表明，干预组和对照组近期登革热感染的发生率相同。大多数参与者对有关用户满意度的问题给予了肯定回答。根据结果，没有证据表明使用MQT进行大规模诱捕可作为登革热控制项目的一部分。这种粘性诱捕器仅推荐用于登革热媒介监测。
