Diagonal arrangement of test and control CFG traps and mosquito release point.
a and b represent the CFG traps at 2 different locations with the cup (c) at equidistant point from each of the traps in the screen house.
Fig 2.
GC profile of most attractive human foot odor.
The numbers represent individual peaks in the foot odour as they get eluted from the GC column; Peak 69 is geranylacetone and major component but not bioactive, while peak 10 n-octanal, 17 (n-decanal), 34 (n-decanal), 42 (4-ethylacetophenone), 52 (n-undecanal) and 77 (n-dodecanal) are bioactive among the other electro-physiologically active ones that are too tiny to be labelled.

Mean mosquito catch sizes* in CFG traps baited with synthetic blends of EAD active foot odor components.
*Based on 8 replicates of mosquito catch sizes per blend; blends not sharing the same letters are significantly different (p = 0.0001).
