“…Scaptocoris castanea Perty, 1830 (Cydnidae) is a pest of cotton, corn, soybean, and pastures (Oliveira & Malaguido, 2004; Pereira et al, 2012) and feeds on roots (JFSC, personal observation). Since salivary glands are the main source of saliva production responsible for damaging the plants (Oliveira & Malaguido, 2004; Matias et al, 2011; Peiffer & Felton, 2014), more detailed information on this organ have yet to be explored.…”

The burrower bug Scaptocoris castanea Perty, 1830 (Hemiptera: Cydnidae) is an agricultural pest feeding on roots of several crops. The histology and ultrastructure of the salivary glands of S. castanea were described. The salivary system has a pair of principal salivary glands and a pair of accessory salivary glands. The principal salivary gland is bilobed with anterior and posterior lobes joined by a hilus where an excretory duct occurs. The accessory salivary gland is tubular with a narrow lumen that opens into the hilus near the excretory duct, suggesting that its secretion is stored in the lumen of the principal gland. The cytoplasm of the secretory cells is rich in the rough endoplasmic reticulum, secretory vesicles with different electron densities and mitochondria. At the base of the accessory gland epithelium, there were scattered cells that do not reach the gland lumen, with the cytoplasm rich in the rough endoplasmic reticulum, indicating a role in protein production. Data show that principal and accessory salivary glands of S. castanea produce proteinaceous saliva. This is the first morphological description of the S. castanea salivary system that is similar to other Hemiptera Pentatomomorpha, but with occurrence of basal cells in the accessory salivary gland.

Burrower bugs are typical pentatomoid insects, small to medium in size, recognized by the morphological adaptations for digging. However, some cydnids live aboveground or on vegetation, feeding on falling seeds or even plant tissues.The family has a worldwide distribution, being well represented in tropical and temperate regions, known in the fossil record since at least the Late Cretaceous. Cydnidae includes more than 750 species in 93 genera, divided in six subfamilies. In the Neotropical region, 145 species are recorded and included in the subfamilies Amnestinae (38 spp.), Cephalocteinae (eight), Cydninae (97), and Sehirinae (one). The monophyly of the Cydnidae and phylogenetic relationships with other pentatomoid families are still controversial. Among the subfamilies, only Cephalocteinae has a strong support in a phylogenetic context. Burrower bugs are phytophagous and seem to be polyphagous, and although the group has been considered of little economic importance, damage to crops in the Neotropical region has been growing in the last 15 years. Because of the burrowing habits and small size of most of the species, people unnoticed its presence, limiting taxonomic characterization, host plants records, as well as damage and symptoms to cultivated plants. In this chapter, an overview of the group in the Neotropical region is presented, including an identifi cation key for subfamilies and genera with the characterization of the commonest species.
