(Florida Entomologist 90(1), 175-179, March 2007, 2007-03)
The results of previous studies that showed that exposing mass-reared male Mediterranean fruit flies Ceratitis capitata (Wiedemann) to ginger root oil (“aromatherapy”) increases the likelihood of mating with wild females ...
Acoustic courtship songs in males of the fruit fly Anastrepha ludens (Diptera: Tephritidae) associated with geography, mass rearing and courtship success
(Rev. Biol. Trop. 57 (Suppl. 1): 257-265. Epub 2009 November 30., 2009-11-30)
The Sterile Insect Technique (SIT) has been used successfully to control or eradicate fruit flies. The commonly observed inferiority of mass-reared males, compared with wild males, when they are paired with wild females, ...
