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

Biology and Seasonal Abundance of Hymenopterous Parasitoids of Sorghum Midge (Diptera: Cecidomyiidae)

Factors Influencing Emergence of Juveniles from Cysts of Heterodera zeae.

Several factors were studied to determine their effects on hatch and emergence of second-stage juveniles (J2) from cysts of Heterodera zeae. The optimum temperature for emergence of J2 from cysts of H. zeae was 30 C. No juveniles emerged from cysts at 10 or 40 C. Immersion of cysts in 4 mM zinc chloride solution stimulated 10% greater emergence of J2 than occurred in tap water controls during 2...
