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...

Within-Field Distribution of the Sunflower Midge (Diptera: Cecidomyiidae)

The sunßower midge, Contarinia schulzi Gagné (Diptera: Cecidomyiidae), is a pest of cultivated sunßower (Helianthus annuus L.). Larval feeding can cause damage and yield loss to the sunßower head. Adult emergence is extended and larvae are well protected in the sunßower receptacle, making chemical control methods difÞcult and expensive. Sunßower midge enter sunßower Þelds at the edges but Þeldw...

Thermal Requirements for Emergence of Overwintered Sorghum Midge (Diptera: Cecidomyiidae)

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...
