| Popis: | 107 The Phytoseiidae, one of the most well-known mite families, contains more than 2,700 recorded species worldwide. Certain phytoseiids are used as biocontrol agents. They prey on phytophagous pests, including spider mites, eriophyid mites, and small insects, thus valuably contributing to the agroecosystem. In order to study, apply and monitor accurately on the appropriate species, a reliable Taxonomy of Phytoseiidae is urgently needed. Fifty-three species of Taiwanese phytoseiids have been recorded since the 1970s, with major contributions from Tseng and other acarologists. However, several problems must be solved: (1) previous investigations have mostly been restricted to agricultural areas or suburbs; (2) descriptions of adult males for most species are lacking; (3) some parts of the descriptions, drawings, and synonyms are ambiguous; (4) all collections by Tseng, including type specimens, are missing; (5) biological information on phytoseiids is lacking. This study comprised a general review of the classification and external morphology of the family Phytoseiidae in Taiwan and neighboring islands. During 2009－2019, more than 20,000 specimens with 2,500 collection records were found. This study dealt with 62 species belonging to 3 subfamilies, 14 genera, including 5 new species and 5 newly recorded species were reported before. It was provided descriptions, illustrations, and also informations on habitat plants and food habits were recorded. Five points were discussed separately: 1. biodiversity of phytoseiid mites from Taiwan; 2. Tseng’s specimens mystery; 3. additional characters in Taxonomy of Phytoseiidae; 4. any possible potential predator species? 5. mite slide preparation. This study will not only extend biodiversity database of Taiwan but provide framework for future biological control of phytoseiids. |
