Abstract

Selected morphological and physiological properties of the corpus allatum (CA)–corpus cardiacum (CC) complex from the two-spotted stinkbug, Perillus bioculatus (Hemiptera: Pentatomidae), were studied. The CAs play an important role in insect physiology because of their production of the juvenile hormones (JHs), i.e., key hormones involved in development and reproduction. We found that the P. bioculatus CA–CC complex is present in two distinct morphological forms, the more frequently observed complex containing one “fused” CA between two CCs and the more rarely observed complex having one CA laterally attached to each CC. These complexes were tested for their ability to synthesize JH-like compounds. We found that the primary lipophilic compound synthesized by the CA–CCs migrated differently from JH III (a JH found in numerous insect species) when subjected to thin-layer chromatography. Furthermore, the synthesis of this compound is stimulated by 2E,6E-farnesol, a known precursor for JH III. These data indicate that the P. bioculatus CA– CC product has chemical properties similar to that of other (as of yet unidentified) hemipteran JHs. In addition, we found that the synthesis of this product is sensitive to pH and buffer type; minimally or not affected by the absence of the CC; expressed at similar levels in days 5–30 postemergent adults; and inhibited or decreased in adults reared under low temperature–short day conditions.
