Bionomics and cecidogenesis of Contarinia petioli (Kieffer) (Diptera, Cecidomyiidae)

Occurrence of the new invasive insect Contarinia nasturtii (Diptera: Cecidomyiidae) on cruciferous weeds.

Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae), a common insect pest in Europe and a new invasive pest in North America, causes severe damage to cruciferous crops. In the United States, C. nasturtii was first reported in western New York in 2004. From 2005 to 2007, field surveys were conducted in western New York to investigate the occurrence of C. nasturtii in weeds that might serve a...

Contarinia manii sp. n. (Diptera, Cecidomyiidae): inducer of a remarkable gall on Acacia ferruginea in southern India

Contarinia manii (Diptera: Cecidomyiidae) is described as a new species, on the basis of adults reared from remarkable 'cylinder-piston' galls formed from contiguous leaflets of Acacia ferruginea D.C. in southern India. These galls have been known since 1952 but adults were not reared until 2007. The new species, and another Indian species, Contarinia ramachandrani (Mani), induce similar but di...

Taxonomy of Janetiella thymi (Kieffer) (Diptera: Cecidomyiidae) and of the Species Formerly in Janetiella That Feed on Vitis (Vitaceae)

—The poorly known European species Janetiella thymi (Kieffer), type species of Janetiella Kieffer (Diptera: Cecidomyiidae), is redescribed. Gall makers on grape that were formerly placed in Janetiella are shown to be distinct from that genus and transferred to Vitisiella Fedotova & Kovalev, a genus recently erected for a species on grape in Siberia. Among the distinguishing traits of Vitisiella...

Checklist of the Cecidomyiidae (Diptera) of Finland

A list of the 356 species of Cecidomyiidae (Diptera) recorded from Finland is presented, which comprises 6 Lestremiinae, 156 Micromyinae, 16 Winnertziinae, 69 Porricondylinae, and 109 Cecidomyiinae. The faunistic knowledge of Finnish Winnertziinae, Porricondylinae and Cecidomyiinae is regarded as particularly poor. Based on species numbers known from other countries in Europe, a conservative es...
