Comments: Euseius finlandicus is a common species on decidious trees ( McMurtry and Croft, 1997). It has been reported from New Zealand, Hungary, Serbia, Italy, France, Japan and the USA ( Collyer, 1980; Ripka et al., 2013; Demite et al., 2014). It has been collected from almost every region in Turkey and on different plants, including apple, citrus, grape, hazelnut, pear and walnut ( Swirski and Amitai, 1982; Düzgüneş and KılıÇ, 1983; Şekeroğlu, 1984; Ozman and Cobanoğlu, 2001; Çobanoğlu, 2004; İncekulak and Ecevit, 2002; Yanar and Ecevit, 2005; Kasap et al., 2008, 2009; Denizhan and Çobanoğlu, 2009; Ozsisli and Çobanoğlu, 2011; Yeşilayer and Çobanoğlu, 2011; Satar et al., 2013; Kumral and Çobanoğlu, 2015; Akyazı et al., 2016, 2017; Çobanoğlu and Güldali, 2017; Soysal and Akyazı, 2018). This species is included in the type IV classification of McMutry and Croft (1997), which means that it is a specialized pollen feeder/generalist predator ( McMurtry, 1983; McMurtry and Croft, 1997). It can feed on tetranychid, eriophyid, tyroglyphid and tarsonemid mites, pollen, fungal spores and hyphae, the eggs and larvae of insects, honeydew and plant liquids ( Schausberger, 1992; Kostiainen and Hoy, 1994; Abdallah et al., 2001).
