“…The presence of epidermal glands is a common feature in Hemiptera, being reported for several families either belonging to Heteroptera (true bugs) (Roell et al, 2020) or Homoptera (psyllids, aphids, scales) (Chen & Qiao, 2012; Ammar et al, 2015, 2013). For these insects, the role of the secretion is very diverse, including sexual communication (aphids and scales) (Boullis & Verheggen, 2016; Tabata & Ichiki, 2016), repellence or self-defence (true bugs) (Lockwood & Story, 1987; Krall et al, 1999), as well as release of wax or other protective material (scales, mealybugs) (Foldi & Pearce, 1985; Ahmad et al, 2020).…”

The Cicadomorpha Philaenus spumarius, Neophilaenus campestris and Cicadella viridis are known transmitters of the bacterium Xylella fastidiosa. Here, we studied the ultrastructural organization of their cephalic glands. Our investigations with scanning, transmission, FIB-SEM electron microscope and light microscope revealed for the first time in Auchenorrhyncha the presence of two types of cephalic glands. Both belonged to the class III epidermal glands, according to Noirot and Quennedey classification. Type I glands were the most common, being mainly located around antennae, lorum and gena. Moreover, these glands were observed also on the abdomen and thorax, always in association with sensilla trichoidea. The second type of glands were located exclusively at the apical part of the postclypeus in P. spumarius and N. campestris. The ultrastructural organization was similar in both types, being composed of a secretory cell and a conducting canal. Differences were observed in the width of the cuticular opening, being smaller in the type II glands. In addition, we have recorded the presence of a maxillary sensory pit in all species and described sensilla trichoidea ultrastructural organization. Finally, we discussed the ultrastructural organization of the glands and their potential biological role.

The Cicadomorpha Philaenus spumarius, Neophilaenus campestris, and Cicadella viridis are known transmitters of the bacterium Xylella fastidiosa. Here, we studied the ultrastructural organization of their cephalic glands. Our investigations with scanning, transmission, focused ion beam-scanning electron microscopes and light microscope revealed for the first time in Auchenorrhyncha the presence of two types of cephalic glands. Both belonged to the Class III epidermal glands, according to the Noirot and Quennedey classification. Type A glands were the most common, being mainly located around antennae, lorum, and gena.

Stink bugs (Hemiptera, Pentatomidae) are well known by the strong odor of the defensive compounds they release, which can mediate intra‐ and/or interspecific interactions. Pentatomidae is one of the largest families of Heteroptera and includes many phytophagous species that are considered pests of various crops, as well as predatory species that provide biological control. Against this background, numerous research papers in Chemical Ecology have focused on communication within this group. This paper reviews the chemical compounds reported for nearly ninety taxa, including sex and aggregation pheromones for fifty‐three species of Pentatomidae. Based on these pheromones and proposed biosynthesis pathways, we hypothesize that sex/aggregation pheromones could play a role in taxonomic groups. Characters were determined and evaluated according to their distributions in recent taxonomic classifications, allowing for the inference of the phylogenetic positioning of three species never evaluated in previous taxonomic analyses.
