Studies on a rapid adaptation of the Mediterranean fruit fly
1986
Muñiz, Mariano
Preliminary experiments in the Instituto Español de Entomología show that it is possible a rapid adaptation progress of a newly collected field population of Ceratitis capitata (Wied). Starting with 4 pairs from grapefruits brought in the laboratory from Valencia (Spain) in April,1984,a good daily oviposition rate in the F1 was obtained (about 50 eggs/female). Although the egg production and the survival of larvae to pupation were low during the parental generation,hatchability,pupal production and adult emergence were near to 100% during the following generations. At the end of July a population of about 2.000 adults was obtained (F2). Conditions during the experiments were 22ºC, 70%RH and 12:12 hrs.light regime (1.900 lux).
