Summary
Paired laboratory arm-in-cage and field human-landing topical evaluations of IR3535 versus DEET against multiple mosquito vectors in Thailand.
Key findings
In the lab IR3535 and DEET gave comparable complete-protection times against Aedes aegypti (~9.7-9.8 h) and Culex spp. (~12.7-14.8 h); against Anopheles dirus IR3535 was shorter (3.8 h vs 5.8 h). In the field both gave 94-100% protection for at least 8 h against Ae. albopictus and at least 5 h against Culex and Anopheles.
Limitations
Single country; IR3535 weaker than DEET specifically against Anopheles dirus; lab CPTs use one mosquito density.
