Predicted Distribution of Cx tritaeniorhychus in the Republic of Korea. Red and orange – higher probability of Cx tritaeniorhychus occurrence. Blue – lower probability of Cx tritaeniorhychus occurrence (corresponds to higher elevations). Purple and white dots – mosquito collection sites. White dots were used for model building (training points) while purple dots were withheld from the model and used for testing the accuracy of the model. This work demonstrates that cropland conditions, primarily rice fields and minimum temperature in the summer, are positive factors in predicting this mosquito’s distribution; whereas forested hills and mountains >1000 m elevation, are negative factors.
