The genus Amblyseius (Acarina: Phytoseiidae) in Canada and Alaska

Abstract

Three genera in the subfamily Phytoseiinae (Acarina: Phytoseiidae) are known to occur in Canada and Alaska: Phytoseius Ribaga, Amblyseius Berlese, and Typhlodromus Scheuten. Chant (1965b) reviewed the genus Phytoseius in Canada. The present paper, based on examination of more than 5000 specimens, describes, keys, and figures the 48 species of Amblyseius known to occur in Canada and Alaska, and includes full collection records. Thirty-two new species are described. Chant's (1965a) generic diagnosis is followed.
