Tolerance of lemons and the Mediterranean fruit fly to carbonyl sulfide quarantine fumigation.

Lemons (Citrus limon Burm.) were evaluated for their tolerance to carbonyl sulfide (COS) fumigation and the influence of COS on market quality. At 70 mg l-1 no significant deleterious changes occurred in market quality up to a fumigation duration of 8 h and only a slight amount of peel injury was observed after 12 h. Longer fumigations lead to the presence of an offensive off-odor in the juice as well as to increasing rind injury. A test of the sensitivity of the Mediterranean fruit fly (Ceratitis capitata Wiedemann) to COS indicated that long fumigation times (more than 8 h) will likely be required to achieve a degree of mortality sufficient for quarantine purposes for this insect. The tolerance of lemons to COS observed in this study suggests that COS is suitable for use as a quarantine treatment for this commodity. Its adoption, however, for this purpose will be hampered by the relatively long fumigation times needed and the odor that temporarily accompanies the fruit following fumigation.
