Low H₂O₂ and enhanced oxidative resistance in the diapause-destined pupa of silkworm, Antheraea mylitta (Lepidoptera:Saturniidae) suggest their possible involvement in dormancy and lifespan extension

Insect diapause is associated with physiological dormancy, extension of life span and an altered developmental programme. Reactive oxygen species, oxidative damaged products and antioxidants are being increasi...

Micro-CT imaging of live insects using carbon dioxide gas-induced hypoxia as anesthetic with minimal impact on certain subsequent life history traits

Live imaging of whole invertebrates can be accomplished with X-ray micro-computed tomography (micro-CT) at 10-100 μm spatial resolution. However, image quality could be compromised by the movement of live subj...

Shoaling promotes place over response learning but does not facilitate individual learning of that strategy in zebrafish (Danio rerio)

Flexible spatial memory, such as “place” learning, is an important adaptation to assist successful foraging and to avoid predation and is thought to be more adaptive than response learning which requires a con...
