Physiological and transcriptional changes associated with obligate aestivation in the cabbage stem flea beetle (Psylliodes chrysocephala)

This study investigates physiological and transcriptional changes in the cabbage stem flea beetle during aestivation, finding reduced carbohydrate reserves, increased lipid reserves, and differential expression of metabolism-related genes.

A specialist flea beetle manipulates and tolerates the activated chemical defense in its host plant

This study investigates how the flea beetle Phyllotreta armoraciae sequesters glucosinolates from its host plant and tolerates their hydrolysis, showing that plant myrosinases reduce sequestration but beetles avoid gut hydrolysis through absorption and inactivation of myrosinases.
