Hormesis-like effect of mild larval crowding on thermotolerance in Drosophila flies (doi:
In insects, some studies investigated microbiota effects on thermotolerance.
Received 26 November 2012 Received in revised form 11 January 2013 Accepted 31 January 2013 Thermal acclimation drastically alters thermotolerance of ectotherms, but the mechanisms determining this plastic response are not fully understood.
To cope with stressful environmental temperatures, organisms can enhance thermotolerance when exposed to sub-lethal temperatures before thermal stress, a phenomenon referred to as thermal acclimation.
Most ectothermic animals have the capacity to modify their thermotolerance to cope with environmental fluctuations.
The spotted wing drosophila, Drosophila suzukii, is an invasive fruit pest that, like many other species, enhances its thermotolerance in response to thermal acclimation.
In Drosophila melanogaster, evidence of such a decline in young adults has only been reported for thermotolerance.
melanogaster has the capacity to enhance thermotolerance in response to a pre-exposure to sub-lethal temperature (Hoffmann, Sørensen &
Interestingly, the temporal metabolic trajectories during the recovery period were similar in young and old ﬂies, despite strong diﬀerences in thermotolerance.
Inducible and constitutive heat shock gene expression responds to modification of Hsp70 copy number in Drosophila melanogaster but does not compensate for loss of thermotolerance in Hsp70 null flies.
