In the field in Iraq Ectomyelois ceratoniae had four generations on an artificial diet and four to five generations on pomegranate fruits. On an artificial diet the mean time for development from egg to adult ranged from 41 to 59 days for the first three generations. Fourth-generation larvae entered diapause in the fall and averaged 241 days. Insect population increased progressively during the fruiting season. Mean percentage of infestation increased from 20% by early generations to more than 80%. High infestation was observed in southcentral areas of Iraq. Orchards in which sanitation was poor were highly infested.

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.

[en] Disinfestation of packed dry dates, Zahdi varity in standard cartons, such as are used in the industry was studied by using gamma radiation or methyl brpmide fumigation. The dose distribution of radiation from gamma beam-650 facility with a Co-60 source was calculated and the best feasible uniforming ratio= 1.4 was followed where the average absorbed dose of 15 point was 75.65 Krad. The results of examination indicated that a complete disinfestation was achieved in both methyl bromide and radiation treated boxes when stored for 25 d. The live insects found in the irradiated dates were genetically sterile and developmentally inactive. While on longer periods of storage (55 or 80 d.), live, active and fertile insects have been found in the treated as well as untreated (control) boxes indicating reinfestation cases.(5 tabs., 10 figs., 22 refs

[en] The disinfestation effect of 70-krad gamma radiation on artificially infested packed dates (Zahdi variety) relative to fumigation with methyl bromide, and the effect of combination treatment of gamma radiation (0, 35, 70, 105 krad) and heat (40 C) on Oryzaephilus surinamensis adult mortality, have been studied. Treatment with 70-krad gamma radiation, or fumigation with methyl bromide, led to a complete and satisfactory insect disinfestation of dates, though disinfestation by 70 krad required a comparatively long period to bring about 100% mortality, in contrast to the more or less direct killing effect of methyl bromide. However, the combination treatment (particularly 35 krad+ 40 C) appears very promising as it reduces by half the period of time required for killing all O. surinamensis adults, and simultaneously ensures full sterility and complete inhibition of reproduction in this insect.(author)
