Cold treatment at 0.0 °C with different exposure durations (0–12 days) was applied to the Mediterranean fruit fly Ceratitis capitata (Wiedemann) fed on a lab diet. The examined developmental stages were early eggs (<6 h), late eggs (>42 h), first instar, second instar and third instar larvae. Pupation, adult emergence and sex ratios of survived flies were investigated to study the C. capitata responses to this low temperature treatment. Our results showed that exposure time at low temperature has a clear effect on pupation and adult emergence. Based on pupation ratios, the first and third instar are the most cold tolerant stages, with LT99 = 7.3 for both of them. Cold tolerance at both stages are very close and no significant differences were detected. There were no significant differences on C. capitata sex ratios among different stages after treatment. This study improves our understanding of C. capitata responses to cold treatment, which may assist in the improvement of the current treatment strategies to control this destructive horticulture pest species.

Cold treatment at 0.0 °C with different exposure durations (0-12 days) was applied to the Mediterranean fruit fly Ceratitis capitata (Wiedemann) fed on lab diet. The examined developmental stages were early eggs (<6 hr) (E.E), late eggs (>42 hr)(L.E),first instar (1st ), second instar(2nd ) and third instar larvae (3rd ). Pupation, adult emergence and sex ratios of survived flies were investigated to study the C. capitata responses to this low temperature treatment. Our results showed that based on pupation ratios, the 3rd instar is the most cold tolerant stage with LT99=7.36 days. The second most cold tolerant stage is the 1st instar with LT99=7.33 days. Cold tolerance at both two stages are very close, so they should be paid attention during the cold treatment. There were no significant differences on C. capitata sex ratios among different stages after treatment. This study improves our understanding of C. capitata responses to cold treatment, which may assist in the improvement of the current treatment strategies to control this destructive horticulture pest species

In a series of tests during 1974 export grade Granny Smith apples artificially infested with eggs, young and old larvae of Mediterranean fruit fly (Ceratitis capitata (Wied.)) were cold stored at 0.5�C � 0.5�C for 14 days and at 1.5�C � 0.5�C for 16 days in simulated commercial conditions. No survivors were recorded from tests in which an estimated total of 340,200 eggs and larvae were treated. No injury to the fruit was caused by the treatments. Apples are held in cool stores after harvest at these temperatures as normal commercial practice. The experimental programme demonstrated that such commercial treatments can be applied to meet export requirements to obtain entry to quarantine areas.

Abstract Population fluctuations of the Mediterranean fruit fly (medfly), Ceratitis capitata, were investigated between 1999 and 2001 at several locations representing fruit production areas in the southern part of Syria (Damascus Ghota, Zabadani, Sargaiah, Rankus, Orneh and Ain Al-Arab). Medfly adults were monitored weekly all year around using Jackson traps baited with trimedlure dispensers. Larvae were also sampled in Damascus Ghota by collecting fruits from ripe or ripening fruit trees and recording the number of larvae emerged from these fruits. In addition, suspected overwintering refuges were sampled at weekly intervals during the three coldest months of the year (December – February) and the number of collected larvae was recorded. The results of trap catches and fruit sampling studies showed a similar pattern of occurrence of medfly populations in the study areas, particularly in Damascus Ghota, during the three years of the study. In Damascus Ghota, flies were caught continuously from early June to late December with some variability between years. Two distinct periods of high fly activity were observed: the first one occurred in August and the second in November with a much higher amplitude. In general, seasonal fluctuations in the pattern of occurrence were influenced by differences in temperature and abundance of preferred host fruits. Traps on fig Ficus carica and oriental persimmon Diospyros kaki trees caught the highest numbers of flies, and fruits collected from these trees showed the highest level of infestation, reaching 100% for fig fruit late in the season. Sampling fruits (in Damascus Ghota) from trees during the three coldest months of the year showed that a small population of medfly larvae was able to survive winter conditions in prickly pear Opuntia vulgaris fruit left on the trees. In the other areas of the study (Zabadani, Sargaiah, Rankus, Orneh and Ain Al-Arab), only a few flies were caught.
