Agromyzidae is a large and cosmopolitan fly family with approximately 2,500 known species. Here we present 22 new records of agromyzid-host plant associations. Plants were sampled from 2002 to 2005 in São Paulo state, Brazil. A total of eight agromyzid species were reared from 18 Asteraceae host species. The genus Melanagromyza Hendel was the commonest. This is the first detailed study reportin...

A checklist of the Agromyzidae (Diptera) recorded from Finland is presented. 279 (or 280) species are currently known from the country. Phytomyzalinguae Lundqvist, 1947 is recorded as new to Finland.

A field test carried out in an industrial greenhouse in Lithuania revealed the attractiveness of synthetic methyl salicylate (MeSa) towards an economically important leafmining tomato pest, Liriomyza bryoniae (Kaltenbach) (Diptera, Agromyzidae). The behavioural reaction of the flies depended very much on the simultaneous presence of both olfactory and visual stimuli. The attractiveness depended...

The 27 Californian species of the genus Melanagromyza Hendel (Diptera: Agromyzidae) are reviewed, including descriptions of three new species (Melanagromyza californiana sp. nov., M. chemsaki sp. nov. and M. gonzalesina sp. nov.) and the first record for one species (Melanagromyza martini Spencer) for California and the USA. All species in California are described or redescribed, with illustrat...

The Ecuadorian Agromyzidae described by Theodor Becker from the Mission du service géographique de l'armée pour la mesure d'un arc de méridien équatorial en Amérique du Sud are revised and several taxonomic changes are proposed. The eight named species identified by Becker actually comprise 14 species of Agromyzidae (3 Melanagromyza, 4 Cerodontha, 6 Liriomyza, 1 Nemorimyza) and one species of H...

Chorebus (Stiphrocera) hexomyzae sp. n. (Hymenoptera, Braconidae, Alysiinae, Dacnusini) is described and illustrated. It was reared from twig galls of Hexomyza caraganae Gu (Diptera, Agromyzidae) on Caragana korshinskii Kom. f. (Fabaceae) in Ningxia and Inner Mongolia (NW China). A partial key to related or similar Chorebus species is provided.

The 29 species of the subfamily Agromyzinae in Thailand are revised, among these 13 species are described as new to science: Melanagromyza ancyla sp. nov., M. catalexis sp. nov., M. cirrappendicula sp. nov., M. lunulata sp. nov., M. macilenta sp. nov., M. multistriata sp. nov., M. pandiculata sp. nov., M. sexseriata sp. nov., M. spinuliloba sp. nov., M. turgida sp. nov., Ophiomyia flagellata sp...

The genus Pseudonapomyza (Diptera: Agromyzidae) includes the main leafminer pests for monocots. Three new species are described that were captured using Malaise traps in "Tinença de Benifassà", "Font Roja" and "Lagunas de La Mata-Torrevieja" (Spain) Natural Parks: Pseudonapomyza curvata n. sp., P. longitata n. sp., and P. sicicornis n. sp. Systematics. Ecological data are discussed.
