Mango is an important tropical fruit only after banana in Hainan Province.In recent years,as a result of pesticide abuse,thrips become one of the main pest insects while they are less important in the past.The nymphs and adults of thrips damage mango flowers, leaves,buds and fruits using their mouthparts,seriously affecting the growth and fruit quality of mangos.This study investigated the major mango-growing areas,including 4 counties and 3 cities of Hainan Province,such as Dan Zhou City,Chang Jiang County,etc.A total of 1241 thrips adult specimens were collected.They belong to 10 species,among which 9 are phytophagous including Scirtothrips dorsalis Hood,Thrips hawaiiensis(Morgan),Thrips physapus Linnaeus,Stenchaetothrips victoriensis(Moulton),Selenothrips rubrocinctus(Giard),Heliothrips haemorrhoidalis(Bouché),Rhipiphorothrips cruentatus Hood,Rhipiphorothrips pulchellus Morgan, and Haplothrips chinensis Priesner;and one predatory,Aeolothrips fasciatus(Linnaeus).The yellow tea thrips is the dominant species, representing 75.51% of all specimens,and is also the most widely-distributed species at all sample sites.
