Examples

• The researchers identified several nonvector species in the study area.
• Nonvector insects do not pose a risk for disease transmission.
• The lab maintained both vector and nonvector populations for comparison.
• Scientists studied why certain mosquito species remain nonvector.
• The nonvector control group showed no pathogen transmission.
• Identifying nonvector organisms helps focus disease prevention efforts.
