we found u. macrorhiza to be capable of preying on first- through third-instar ae. aegypti larvae. these results are in line with previously published work [ 80 ], which suggested that u. macrorhiza can predate mosquitoes at three stages of development. these results were consistent when repeated at smaller water volumes. in comparison to the predation experiments at larger volumes, the survival of larvae exposed to a single bladder on small cuttings of u. macrorhiza is at first glance reduced. however, the bladder to larva ratio in the latter experiment was 1:1, whereas the previous experiments had a ratio of 10:1. while control of larvae at such small water volumes is impractical, these results demonstrate that small water volume is not on its own a limiting factor in the application of u. macrorhiza.

most of the previous interventions in lsm employed vertical management with only a few using a community-based approach [ 20, 21 ]. to date, no study has been undertaken to examine the effectiveness of lsm through larviciding with bti on malaria control in rwanda. in the framework of a community-based malaria elimination project implemented in 2012 [ 22 ], a comparative community-based lsm intervention using bti was conducted in ruhuha, rwanda, in 2015. recognizing that working with communities, not only as groups directly affected by malaria but also as critical partners for creating and maintaining larval habitats, would lead to a more effective programme [ 23 ], the intervention deployed a community-based approach with in-built baseline and endline socio-economic study for outcome evaluation. the current paper describes baseline and endline community awareness and acceptance of the lsm intervention using bti. secondly, the paper highlights challenges faced during the implementation and formulates recommendations for future community-based larviciding activities on a larger scale. a companion paper (hakizimana et al.) will separately describe the entomological impact of this community-based biological control programme.
