OVIPOSITIONAL ANTIXENOSIS TO CONTARINIA SORGHICOLA (COQUILLETT) (DIPTERA: CECIDOMYIIDAE) IN GRAIN SORGHUM

Factors Influencing Adult Emergence from Diapausing Sorghum Midge, Contarinia sorghicola (Diptera: Cecidomyiidae

New knowledge on the sorghum midge, Stenodiplosis sorghicola Coquilett 1899 (Diptera: Cecidomyiidae), in the south of France

Complete floret abortion on sorghum panicles due to sorghum midge (Stenodiplosis sorghicola) infestation was observed just after flowering onset in early August (2008) in fields near Montpellier (France). With the aim of controlling these infestations, mathematical models simulating the biological development of the insect as a function of temperature, which were developed in Texas (USA) and ad...

Thermal Requirements for Emergence of Overwintered Sorghum Midge (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...
