“…Recently, Abé and Ohba (2016) compiled information on water mite parasitism on aquatic organisms in Japan. According to their report, most of the studies on water mite parasitism in Japan treat dipteran hosts (Yamada, 1918;Miyazaki, 1933Miyazaki, , 1935Miyazaki, , 1936Miyazaki, , 1945Miyazaki, , 1947Uchida and Miyazaki, 1935;Imamura, 1950aImamura, , 1951aImamura, , 1951bImamura, , 1952aHirabayashi and Fukunaga, 2007). On the other hand, studies on mite parasitism on other insect taxa, such as heteropterans (Masuda, 1934(Masuda, , 1942Imamura, 1952b;Nagasawa et al, 2008;Morimoto, 2012;Abé et al, 2015), coleopterans (Masuda, 1934(Masuda, , 1935a(Masuda, , 1935b(Masuda, , 1942, odonates (Miyazaki, 1936;Imamura, 1950bImamura, , 1951cImamura, , 1951dImamura and Mitchell, 1967;Kobayashi and Toda, 2005), and plecopterans (Imamura, 1950c), are rather limited.…”
