Field evaluation of two novel sampling devices for collecting wild oviposition site seeking malaria vector mosquitoes: OviART gravid traps and squares of electrocuting nets

Table 3 Association between trap type and mosquito catch during field evaluation using a generalised linear mixed effects model
