Distribution and importance of polyphagous Liriomyza species (Diptera, Agromyzidae) in vegetables in Vietnam
Norwegian Journal of Entomology 55 (2), 149-164
Abstract: Field collections of polyphagous Liriomyza species were conducted in vegetables in 50 of Vietnams 62 provinces during 2002-2007. A total of more than 16 800 specimens were identified to species. L. sativae Blanchard, 1938 was the dominant species, making up 75.2 % of the total material. It was present and common in all the 50 investigated provinces. L. huidobrensis (Blanchard, 1926) made up 8.6 % of the material and was found in 7 provinces in the central parts of the country, from Dong Nai to Da Nang. L. trifolii (Burgess, 1880) made up 8.4 % of the material and was found in 13 provinces in the central parts of the country, from Ho Chi Minh City to Hue. L. bryoniae (Kaltenbach, 1858) made up 4.0 % of the material and was found in 15 provinces in most of the country north of Ho Chi Minh City. L. chinensis (Kato, 1949) made up 3.0 % of the material and was found in 20 provinces all over the country. It was mainly found in onion (Allium cepa L.). Chromatomyia horticola (Goureau, 1851) made up 0.8 % of the material and was found in relatively low numbers in 9 provinces all over the country from Lam Dong and northwards. The spread of the different species into Vietnam and their possible further spread within the country are discussed, as well as their importance as pest species on different host plants. L. katoi Sasakawa, 1961 is reported from Vietnam for the first time.
