Abstract

A gene causing an 8 h variation in the period of circadian rhythm in the adult locomotor activity was found in the melon fly Bactrocera cucurbitae by artificial selection for development time from egg to adult eclosion at 25 ± 2°C. The periods of free-running rhythm (mean ± SD) in constant darkness were 22.6 ± 0.6 and 22.5 ± 0.4 h, respectively, in two replicate lines selected for short development time, and 30.9 ± 0.9 and 26.5 ± 3.6 h, respectively, in two replicate lines selected for long development time. Thus, the development time and the period of circadian clock were correlated. The period locus was autosomal.
