Cold Response of the Mediterranean Fruit Fly (<i>Ceratitis capitata</i>) on a Lab Diet

Cold treatment at 0.0 &#176;C with different exposure durations (0&#8315;12 days) was applied to the Mediterranean fruit fly <i>Ceratitis capitata</i> (Wiedemann) fed on a lab diet. The examined developmental stages were early eggs (&lt;6 h), late eggs (&gt;42 h), first i...

description Cold treatment at 0.0 &#176;C with different exposure durations (0&#8315;12 days) was applied to the Mediterranean fruit fly <i>Ceratitis capitata</i> (Wiedemann) fed on a lab diet. The examined developmental stages were early eggs (&lt;6 h), late eggs (&gt;42 h), first instar, second instar and third instar larvae. Pupation, adult emergence and sex ratios of survived flies were investigated to study the <i>C. capitata</i> 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 <i>C. capitata</i> sex ratios among different stages after treatment. This study improves our understanding of <i>C. capitata</i> responses to cold treatment, which may assist in the improvement of the current treatment strategies to control this destructive horticulture pest species.
