A Comparison of dietary protein content between praying mantises and other insects. B Phylogenetic analysis showing that the Trypsin gene family was significantly expanded in H. coronatus and D. lobata. C Schematic representation of the tandem replication of the Trypsin gene cluster in praying mantises. Each arrow indicates a complete gene oriented in the 5′ to 3′ direction. D A color diagram showing the expression level of Trypsin in the head, thorax, leg, and abdomen tissues. E Detection of trypsin enzyme activity in the intestines of a carnivorous mantis and an herbivorous cricket. Data represent the mean ± standard deviation of four replicates. * p = 0.04 by two-sided Student’s t tests.
