New hosts and records of plant feeding mites for Costa Rica: interval 2002-2008.
An update is presented for the species of plant feeding mites identified for Costa Rica, along with their host plants, from 2002 to June 2008. A total of 159 new host plants for phytophagous mites, grouped in 52 families, are mentioned. Tetranychus urticae was the most abundant species, which is reported from 49 new hosts for the country. Moreover, the other species collected were Tetranychus abacae, Tetranychus ludeni, Tetranychus marianae, Tetranychus mexicanus, Tetranychus neocaledonicus, Tetranychus tumidus, Oligonychus yothersi, Panonychus citri, Schizotetranychus sp., Sonotetranychus vaneyndhoveni, Mononychellus estradai, Eutetranychus banksi and Paraponychus sp. Brevipalpus californicus, Brevipalpus obovatus and Brevipalpus phoenicis are mentioned along with Tenuipalpus pacificus. Tuckerella pavoniformis is also included, which was found in a new host for Costa Rica and the world. Polyphagotarsonemus latus and Phytonemus pallidus were collected acting as pestsin some crops, including Hemitarsonemus tepidariorum on leather leaf fern (Rumohra adiantiformis [Arachniodes adiantiformis]) and Steneotarsonemus spinki on rice. The mites in the family Eriophyidae were collected from different hosts, showing that most of the species found are not informed from other areas being, probably, new species to science. Field diagnosis is also offered for some chosen species within the 5 families studied.
