Antibiosis component of resistance in sorghum to sorghum midge, Contarinia sorghicola

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

Inheritance of Resistance to Sorghum Shoot Fly, Atherigona soccata in Sorghum, Sorghum bicolor (L.) Moench

Sorghum production is affected by a wide array of biotic constraints, of which sorghum shoot fly, Atherigona soccata is the most important pest, which severely damages the sorghum crop during the seedling stage. Host plant resistance is one of the major components to control sorghum shoot fly, A. soccata. To understand the nature of gene action for inheritance of shoot fly resistance, we evalua...

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...

Categories of Resistance, Antibiosis and Tolerance, to Biotype I Greenbug (Schizaphis graminum (Rondani) Homoptera: Aphididae) in Four Sorghum (Sorghum bicolor (L.) Moench. Poales:Gramineae) Hybrids

Resistance categories (antibiosis and tolerance) of four sorghum (Sorghum bicolor (L.) Moench) hybrids to biotype I greenbug, Schizaphis graminum (Rondani), were determined in environmental growth chamber and field studies. Greenbug weight and fecundity were lower on ‘Cargill 607E’ compared with ‘Cargill 797’. Percentage of leaf damage area was significantly less on two resistant hybrids (Cargi...
