Changes in Metabolomics Profiles of <i>Propylea japonica</i> in Response to Acute Heat Stress. [PDF]

open access: yesInt J Mol Sci
The ladybird beetle, Propylea japonica Thunberg (Coleoptera: Coccinellidae), is a widely distributed natural predator that is crucial in controlling various agricultural pests in China. Despite frequent references to its remarkable thermotolerance, the molecular mechanisms underlying its thermotolerance remain poorly understood.
