Community knowledge and acceptance of larviciding for malaria control in a rural district of east-central Tanzania
Abstract
The use of microbial larvicides, a form of larval source management, is a less commonly
used malaria control intervention that nonetheless has significant potential as a
component of an integrated vector management strategy. We evaluated community acceptability
of larviciding in a rural district in east-central Tanzania using data from 962 household
surveys, 12 focus group discussions, and 24 in-depth interviews. Most survey respondents
trusted in the safety (73.1%) and efficacy of larviciding, both with regards to mosquito
control (92.3%) and to reduce malaria infection risk (91.9%). Probing these perceptions
using a Likert scale provides a more detailed picture. Focus group participants and
key informants were also receptive to larviciding, but stressed the importance of
sensitization before its implementation. Overall, 73.4% of survey respondents expressed
a willingness to make a nominal household contribution to a larviciding program, a
proportion which decreased as the proposed contribution increased. The lower-bound
mean willingness to pay is estimated at 2,934 Tanzanian Shillings (approximately US$1.76)
per three month period. We present a multivariate probit regression analysis examining
factors associated with willingness to pay. Overall, our findings point to a receptive
environment in a rural setting in Tanzania for the use of microbial larvicides in
malaria control. © 2014 by the authors; licensee MDPI, Basel, Switzerland.
