Mites of the family Phytoseiidae from central Africa, with remarks on the genera of the world

Abstract

DURING RECENT YEARS the taxonomy, bionomics, and control of phytophagous mites have become subjects of intensive study. Phytoseiids, the most important mite predators of plant-feeding mites, are now receiving attention from entomologists with regard to their taxonomy, bionomics, and the effects of agricultural chemicals on their populations. Gilliat (1935), Lord (1949), and Herbert (1952) regarded phytoseiid mites as among the most important predators of spider mites in Nova Scotia orchards. Mathys (1958) stated that mites of the genus Typhlodromus appear to be an effective factor limiting populations of spider mites in Swiss vineyards. Snetsinger (1959, 1960) found Typhlodromus to have a deterrent action on the development of spider mites on apple trees in Illinois. Chant (1958, 1960), however, regarded phytoseiids as of little importance in reducing spider-mite populations on deciduous fruit trees in England. In California, Smith and Summers (1949) found that a phytoseiid played an important part in controlling a heavy infestation of spider mites in a large acreage of strawberries, and Allen (1959) stated that another phytoseiid is the most important enemy of spider mites on strawberries. Huffaker and Kennett (1956) demonstrated the vital role of predation by still another phytoseiid in the control of the cyclamen mite on California strawberries. Fleschner (1958) indicated that phytoseiids may significantly control spider mites on citrus and avocado in southern California, and reasons for this effectiveness were advanced by Chant and Fleschner (1960). Chant (1959) and Chant and Fleschner (1960) have shown that certain phytoseiids may live and reproduce with it diet of pollen or aphid honeydew, which may be important in maintaining populations when mite hosts are not available. Of the few phytoseiid species described by earlier workers, practically none was accurately identified prior to the work of Garman (1948). Since that time about 250 species have been named or are being described. Never-1

Revision of the genus Neoseiulella Muma (Acari: Phytoseiidae). Re-description of species, synonymies assessment, biogeography, plant supports and key to adult females

“…At the same time, Pritchard and Baker (1962) included these three species in the genus Typhlodromus (Seiulus) Berlese. In 1966, Ehara also used the sub-genus Typhlodromus (Seiulus) to designate the tiliarum species group.…”
