Table 1 Association between treatments (pond size and strengths of suction fan) and catching efficiency of OviART gravid trap using a generalised linear mixed effects model

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