“…Hemipteran salivary gland organization is morphologically diverse within different suborders but generally quite similar within a family. The morphological pattern of B. occiduus salivary glands is consistent with that of other Hemipteran salivary glands, consisting of a pair of principal glands and a pair of accessory glands (Dufour 1833, Baptist 1941, Southwood 1955, Bronskill 1958, Sogawa 1965, Miles 1972, Louis and Kumar 1973, Wayadande et al 1997, Oliveira et al 2006, Azevedo et al 2007, Kumar and Sahayaraj 2012, Castro et al 2013. In Hemiptera, the principal gland may be unilobed, bilobed, or multilobed while the accessory gland is always unilobed and vesicular or tubular.…”

The western chinch bug, Blissus occiduus Barber, is a serious pest of buffalograss, Buchloe dactyloides (Nuttall) due to physical and chemical damage caused during the feeding process. Although previous work has investigated the feeding behaviors of chinch bugs in the Blissus complex, no study to date has explored salivary gland morphology and the associated salivary complex of this insect. Whole and sectioned B. occiduus salivary glands were visualized using light and scanning electron microscopy to determine overall structure and cell types of the salivary glands and their individual lobes. Microscopy revealed a pair of trilobed principal glands and a pair of tubular accessory glands of differing cellular types. To link structure with function, the salivary gland proteome was characterized using liquid chromatography tandem mass spectrometry. The salivary proteome analysis resulted in B. occiduus sequences matching 228 nonhomologous protein sequences of the pea aphid, Acyrthosiphon pisum (Harris), with many specific to the proteins present in the salivary proteome of A. pisum. A number of sequences were assigned the molecular function of hydrolase and oxido-reductase activity, with one specific protein sequence revealing a peroxidase-like function. This is the first study to characterize the salivary proteome of B. occiduus and the first of any species in the family Blissidae.

“…The salivary system of P. distinctus is composed of a pair of main salivary glands and a pair of accessory salivary glands with a similar anatomy to that described for other Asopinae such as Brontocoris tabidus Signoret (Azevedo et al, 2007), P. nigrispinus Dallas (Martínez et al, 2014), and Supputius cincticeps Stål (De Castro et al, 2013), suggesting an anatomical pattern similar within the Pentatomidae predators. However, anatomical variations of the salivary glands have been reported for other Hemiptera such as Belostoma lutarium Stål (Belostomatidae) (Swart & Felgenhauer, 2003), Cimex hemipterus Fabricius (Cimicidae) (Serrão et al, 2008), Karenia caelatata Distant (Cicadidae) (Zhong et al, 2013), Mahanarva posticata Stål (Cercopidae) (Roma et al, 2003), and Triatoma infestans Klug (Reduviidae) (Reis et al, 2003).…”

Ultrastructure of the Salivary Glands of the Stink Bug Predator Podisus distinctus

Podisus distinctus (Hemiptera: Pentatomidae) is a zoophytophagous insect with significant potential for use as a biological control agent in agriculture and forestry because their nymphs and adults actively prey on diverse insect species. The saliva of this insect possesses active substances that cause paralysis and death of the prey. As the first step in identifying compounds of P. distinctus saliva, this study describes the ultrastructure of the salivary glands of this predator. The salivary system of P. distinctus possesses a pair of main salivary glands with a short anterior lobe, a long posterior lobe, and a pair of tubular accessory glands. The main salivary gland of P. distinctus has no associated muscles, suggesting that the saliva-release mechanism occurs with the help of certain thorax muscles. The main salivary gland epithelium has a single layer of cells (varying from cubical to columnar) with cytoplasm rich in rough endoplasmic reticulum, spherical granules of different sizes, a nucleus with a predominance of decondensed chromatin, and nucleolus. The apical cell region has a few short microvilli and the basal region has plasma membrane infoldings. The epithelium of the accessory salivary glands possesses a single-layered epithelium of cubic cells delimiting a narrow lumen. The apical cell region has a high density of microvilli and pleomorphic mitochondria, whereas the central cell region is rich in rough endoplasmic reticulum with a well-developed nucleus and decondensed chromatin. The basal cell region is characterized by the presence of several basal plasma membrane infoldings associated with mitochondria and numerous openings to the hemocoel forming large channels. The ultrastructural characteristics suggest that the main salivary glands and accessory salivary glands play a vital role in protein synthesis for saliva production and that the accessory glands are involved in transport of materials of the hemolymph.

“…Compared to the principal salivary glands, these accessory salivary glands were in a form of tubes and were also narrower (Figure 1d). The salivary glands of E. furcellata is composed of a pair of principal salivary glands and a pair of accessory salivary glands that showed similar features to other Asopinae such as Podisus nigrispinus (Martínez et al, 2014), Brontocoris tabidus (Azevedo et al, 2007), Supputius cincticeps (Castro et al, 2013), and Podisus distinctus (Martínez et al, 2015). This suggested a similar anatomical pattern among predators of the Pentatomidae family.…”

“…In addition, the results showed that the rough endoplasmic reticulum and mitochondria were different in the anterior and posterior glandular lobes as they differed in shape and content. This indicates that different secretions may be biosynthesized in these regions (Castro et al, 2013). A similar mechanism was reported for the salivary glands of the spittlebug Mahanarva fimbriolata (Nunes & Camargo‐Mathias, 2006).…”

“…The chemical constituent of its saliva may be responsible for this lethal effect on the prey (Cohen, 1990). However, little is known about the salivary compounds and the structure of the glands that produce them, although the salivary systems of other hemipterans have been studied (Azevedo et al, 2007; Castellanos et al, 2017; Castro et al, 2013; Kumar & Sahayaraj, 2012; Martínez et al, 2014). During periods of low prey availability, E. furcellata feeds on plant sap in the xylem to obtain nutrients (Martínez et al, 2014).…”

Eocanthecona furcellata Wolff (Hemiptera: Pentatomidae) is a native generalist predator which attacks and kills its prey by first inserting its stylet into the prey's body and then injecting saliva into it. Here, we describe the histology and ultrastructure of its salivary glands. The study showed that the salivary glands were made up of pairs of principal and tubular accessory salivary glands. The principal salivary glands were bilobed and consisted of a smaller anterior lobe and a larger elongated posterior lobe. The ducts of the principal and accessory salivary glands were located in a narrow region between the anterior and posterior lobe known as the hilum. The principal salivary gland was lined with a single‐layered epithelium. The cells cytoplasm was enriched with rough endoplasmic reticulum and secretory, and the nucleus showed a higher level of uncondensed chromatin. The basal region of the cell had plasma membrane infoldings. The cytoplasm of the accessory gland was rich in rough endoplasmic reticulum and many large cavities. The ducts of the principal salivary gland were made up of a single layer of flattened cells which had a thin cuticle lining the apical portion. Variation in the lumen content of the different lobes, which made up the principal gland suggested that their chemical products also varied. These results indicate that these two salivary glands produce the proteins found in the saliva.
