The mite abundance is categorized into four levels (zero mite, 1 to 9 mites, 10 to 19 mites, and 20 mites or more). The seasons are spring (April and June 2011, June 2012), summer (August 2011, July, August, and September 2012), and winter (December 2010 and February 2011). The reproduction is whether a male has descended testicles or a female has perforated vagina and is pregnant or lactating. Significant results are in italics.
