From: Inter-annual variation in prevalence and intensity of mite parasitism relates to appearance and expression of damselfly resistance

Figure 4

Mean parasite intensity (number of Arrenurus pollictus mites per infested host) on Lestes disjunctus damselflies at emergence each year plotted against resistance (the % of the mature damselfly population that resisted mites) for 6 years of the 7-year study showing a significant relationship between these two measures. Intensities (± s.e.) for each year are, 2002: 10.2 ± 0.9, 2003: 9.1 ± 0.4, 2004: 54.3 ± 1.8, 2005: 17.6 ± 2.4, 2006: 26.1 ± 2.8, 2008: 5.3 ± 0.5. Intensity was not measured in 2007.
