Figure 3. Attractiveness of lures loaded with 10L. longipalpis caught in test sheds with pheromone lures minus number caught in paired control sheds with no pheromone.

Box and whisker plots show median (horizontal line), interquartile range (box), maximum extreme value within 1.5 of interquartile range (whiskers) and outliers (open circles). Grey boxes indicate significantly more sand flies caught in test sheds than controls (P<0.05, Wilcoxon signed rank test, data log+1 transformed prior to analysis). ‘New’ refers to fresh lures tested one week after 12 week old lures, to confirm that significant numbers of L. longipalpis could still be caught at the end of the sand fly season.
