Accumulation of lipid reserves is considered important for the overwinter survival many animals. Fish are thought to deplete lipids until they reach a critical minimum below which starvation mortality occurs, meaning that lipid-dependent selective may be strong pressure leading life-history evolution favouring accumulation and storage. Much our current knowledge comes from either laboratory stu...

Harmonia axyridis (Pallas) an important natural predator of insect pests has become cosmopolitan invasive species, causing negative ecological impacts worldwide. In this study, relative survival ability, trehalose glycogen contents, activity metabolism-related gene-exp...
