Abstract:

Adaptation of a population of the carob moth, Ectomyelois ceratoniae (Zeller), to laboratory rearing conditions takes six generations. Average larva and pupa periods were 17 and 7 days, respectively; the adult lives 2–10 days. Oviposition ceased after day 8. Polynomial curves of the percentage of fertile females, viable eggs, and progeny per female per day reflect similarity in shapes with three peaks on days 4 and 5. Higher numbers of eggs were laid by laboratory-reared females. Female fertility increased from 22% in the F1 to 42% in the F6. However, unmated females with no eggs laid decreased from 48% in F1 to 17% in F6. Wild males lacked competitiveness and did not transfer sperm to the wild females as frequently as to the fertilized females of the laboratory colony. Higher percentage of eggs hatching was found with three to four pairs in a mating container.
