Abstract
The cabbage stink bug was classified as Pentatomorpha in respect to the external structure of its salivary gland. The form of the posterior lobe, especially the width of its basal portion, varied slightly within the individual species of Pentatomidae. As regards the external and histological structure of the salivary gland of the bug, no essential difference could be discerned among the different stages except for some minor features. It was supposed that the function of the anterior lobe differed from that of the posterior. This could be inferred from the apparent difference between them with regards to the distribution pattern of the contens of the sack and from the existene of large granular substances in the cytoplasm of secretory cells in the anterior lobe. The cytoplasm in both of the lobes cotained vacuoles which varied in number and location with the individual bug of the same species. This suggested that the secretory cell had a continuously varying secretory stage.
