Comparison of trapping methods for use in surveys for potential Culicoides vectors of orbiviruses

Parasites & Vectors

Table 1 The overall mean ± standard error (SE) of specimens per trap-night and mean from 10 species of Culicoides collected in two different types of traps baited with dry ice and deployed overnight during 240 trap-nights from 2016 to 2018 at the Bob R. Jones Idlewild Research Station near Clinton, LA
