Recent challenges in the study of animal behavior are to detect genes related to behavior and how the genes exert their influence on morphological and behavioral plasticity, particularly as related to the mechanism of insect sociability. In this study, we discovered genes related to parental care behavior in social insects. Woodroaches of the genus Cryptocercus provide nutritious materials and symbiotic protists via proctodeal feeding to their young during early developmental stages. Thus, they are a good model species for discovering genes related to parental care behavior. We screened eight differentially expressed genes (DEG1–DEG8) from adult Cryptocercus females exhibiting maternal care behavior. Of the proteins translated from the screened genes, DEG7 showed high homology to apolipophorin-III-like proteins. Analysis of diverse molecular features revealed that DEG7 was a partial clone encoding apoLp-III, which plays essential roles in hemolymph-lipid transport processes in insects. Isolation of full-length cDNAs for the DEGs identified in this study would be very helpful for a functional annotation of the individual genes and further understanding of maternal care behavior at the molecular level in the future.

► Differentially expressed 8 genes (DEG1 to DEG8) were isolated from cockroach females exhibiting maternal caring behavior.
► DEG7 encodes apoLp-III that plays essential roles in hemolymph lipid transport processes in insects.
► The identified genes will be useful resources to better understand maternal caring behavior on the molecular levels.
