Polyphagous Liriomyza species (Diptera: Agromyzidae) in vegetables in Vietnam. (241)
, , , , and
Field collections of polyphagous Liriomyza species were conducted in vegetables in 27 provinces in Vietnam during 1998-2002. More than 3200 specimens were collected and L. sativae Blanchard was the dominant species, comprising 87% of the material. It was present and common in all 27 investigated provinces. Liriomyza huidobrensis made up 12% of the material and was only found in the highlands of the Lam Dong province. Part of the material of L. sativae and L. huidobrensis was examined by using random amplified polymorphic deoxyribonucleic acid (RAPD)-polymerase chain reaction (PCR) analysis. Liriomyza trifolii was not found anywhere in Vietnam, while L. chinensis comprised 1% of the material and was found in the provinces Bac Ninh, Dong Nai, and Ba Ria. The spread of the different species into Vietnam and the possible further spread within Vietnam are discussed. In addition to infesting vegetables, L. sativae was also infesting cotton.
