Hyperprolinemic larvae of the drosophilid fly, Chymomyza costata, survive cryopreservation in liquid nitrogen.
The larva of the drosophilid fly, Chymomyza costata, is probably the most complex metazoan organism that can survive submergence in liquid nitrogen (-196 °C) in a fully hydrated state. We examined the associations between the physiological and biochemical parameters of differently acclimated larvae and their freeze tolerance. Entering diapause is an essential and sufficient prerequisite for att...
متن کاملEffects of temperature and photoperiod on the termination of larval diapause in Lucilia sericata (Diptera: Calliphoridae).
Larvae of the blow fly, Lucilia sericata (Meigen), enter diapause in the third instar after cessation of feeding. The effects of temperature and photoperiod on the termination of diapause were examined. The diapause terminated spontaneously under the diapause-inducing condition of 20 degrees C and LD 12:12, although pupariation was not synchronous. Diapause development proceeded under a low tem...
متن کاملThe Genetic Basis of Natural Variation in Drosophila (Diptera: Drosophilidae) Virgin Egg Retention
Drosophila melanogaster is able to thrive in harsh northern climates through adaptations in life-history traits and physiological mechanisms that allow for survival through the winter. We examined the genetic basis of natural variation in one such trait, female virgin egg retention, which was previously shown to vary clinally and seasonally. To further our understanding of the genetic basis and...
متن کاملPhotoperiod-sensitive developmental delay in facet mutants of the drosophilid fly, Chymomyza costata and the genetic interaction with timeless.
Previously, we demonstrated that the biological clock gene, timeless (tim), is potentially involved in photoperiodic diapause induction in the larvae of the drosophilid fly Chymomyza costata. Suppression of tim transcription was inevitably associated with the loss of diapause induction even under diapause-promoting short-day conditions. In the present paper, I report a novel gene, facet (fa), w...
متن کاملPhenotypic variation of the Aedeagus of Drosophila serido vilela & sene (Diptera: Drosophilidae).
Drosophila serido Vilela & Sene is a polytypic and cactophilic species with broad geographic distribution in Brazil. The morphology of the aedeagi of eight natural populations of D. serido was analyzed. Based on features of their aedeagi, populations of D. serido were discriminated with an efficiency of nearly 75%. The analysis using the Mantel test suggests that the morphological divergence of...
