  abstract = {{E}ntomological indicators of onchocerciasis transmission and the effect of climatic variables on the vector population dynamics were investigated in two first-line villages after more than two decades of mass drug administration with ivermectin. {F}emale blackflies were collected in two villages ({B}ayomen and {B}iatsota) using human landing method for a period of 12 months. {B}lackflies were dissected and entomological indices were computed. {M}onthly temperature, precipitation, and humidity were collected and the {S}pearman correlation rank test was used to assess the relationship between biting rates and climatic variables. {T}he highest biting rates (62,280 bites/human/month in {B}ayomen and 42,090 bites/human/month in {B}iatsota) were recorded during the long rainy season ({N}ovember). {T}he {O}nchocerca volvulus transmission was greater during the long dry season in both villages, with a peak at the beginning of the long dry season in {B}iatsota (100 infective larvae/human/month), and at the middle of the long dry season in {B}ayomen (92 infective larvae/human/month). {N}o correlation was found between biting rates and selected climatic variables in the two villages. {T}his study revealed that onchocerciasis transmission is ongoing in the study area despite almost 25 years of {C}ommunity-{D}irected {T}reatment with {I}vermectin. {I}n accordance with {WHO} recommendations, vector control should be used in combination with mass drug administration to accelerate transmission interruption of onchocerciasis. {T}o be optimal, this vector control should be implemented during the long dry season ({N}ovember to {M}arch) when water volumes are low and transmission potentials are high.},
