Sexual dimorphisms are primary regulated by sex‐biased gene expression. In the present study, using real‐time polymerase chain reaction, we determined the expression profiles of nine genes associated with development, metabolism, stress, and defense throughout adulthood of the Indian meal moth Plodia interpunctella , a global pest of stored food products. Most genes were differentially expressed in a sex‐biased manner during the adult lifespan of the moth. Expression of the heat shock protein genes hsp25 and hsp90 and the antioxidant gene thioredoxin peroxidase ( Tpx ) was highly female biased, whereas the expression of a gene related to host development (ecdysone receptor [ EcR ]) and two genes associated with immunity (β‐glycan recognition protein [ βgrp ] and prophenoloxidase [ ProPO ]) was male biased. In contrast, the expression of hsp70 , glucose‐regulated protein 78 ( grp78 ) and ultraspiracle ( USP ) was not sex biased. The results of the present study provide important insights into the role of sex‐biased genes in the physiology and behavior of P. interpunctella .
