“…Antennal shape and sensilla distribution are the result of environmental selective pressure to increase the efficiency of detecting physical and chemical signals that are crucial in the search for habitat, prey, host, partner, and oviposition site (Elgar et al, 2018 ). Antennal morphology and ultrastructure of sensilla have been reported in several families of Coleoptera, such as Anobiidae (Abd El‐Ghany & Abd El‐Aziz, 2021 ), Bruchidae (Wang, Zheng, Zhang, & Zhang, 2018 ), Cerambycidae (Di Palma, Pistillo, Griffo, Garonna, & Germinara, 2019 ; Dong et al, 2020 ; Faucheux, 2011 ), Carabidae (Di Giulio, Maurizi, Rossi Stacconi, & Romani, 2012 ; Giglio et al, 2008 ; Merivee et al, 2002 ; Ploomi et al, 2003 ), Coccinellidae (Hao, Sun, & Liu, 2020 ; Sevarika, Rondoni, Conti, & Romani, 2021 ), Curculionidae (Chen, Zhang, Wang, & Kong, 2010 ; Romani et al, 2019 ; Shi et al, 2021 ), Elateridae (Faucheux, Németh, Hoffmannova, et al, 2020 ), Scarabaeidae (Shao, Sun, Wang, & Chen, 2019 ; Zauli et al, 2016a , 2016b ), Tenebrionidae (Faucheux, 2013 ; Seada & Hamza, 2018 ), and Buprestidae (Faucheux, Németh, Hoffmannova, et al, 2020 ). However, there is no information on the sensorial pattern of species belonging to Rhysodidae, except for taxonomic studies on the distribution of setae in larval stages (Bousquet & Goulet, 1984 ; Makarov, 2008 ).…”

The habit of feeding on slime moulds (Myxomycetes) commonly present in litter or dead wood requires specific morphological adaptations of the mouthparts and sensory structures involved in the search for habitat and food. In this study, the external morphology of antenna and its sensilla were studied using scanning electron microscopy in the saproxylic beetle, Clinidium canaliculatum, Costa 1839 (Coleoptera, Rhysodidae). Their moniliform antennae consist of a scape, pedicel, and nine flagellomeres. We identified seven different types of sensilla, according to their morphological characteristics: two types of sensilla chaetica (sc1 and 2), two types of sensilla basiconica (sb1 and 2), one type of sensilla campaniformia, one type of sensilla coeloconica, and Böhm sensilla. No sexual dimorphism was found regarding antennal morphology and sensilla type and distribution, except for the sensilla coeloconica. The functional role of these sensilla was discussed in relation to their external structure and distribution, and compared with the current knowledge on coleopteran sense organs. Results are basic information for further physiological and behavioral studies to identify their role in the selection of habitat, food, mates and oviposition sites.

“…In addition to the sensilla trichodea , both sensilla basiconica and sensilla auricillica also possess olfactory functions. Sensilla basiconica feature numerous surface pores, a characteristic observed in many Coleoptera insects (Abd El‐Ghany & Abd El‐Aziz, 2021; Faucheux et al, 2020; Qian et al, 2018; Seada & Hamza, 2018). AlinOBP13 was specifically localized in the lumen of the short sensilla trichodea of Adelphocoris lineolatus and in the lumen below the hair base (Sun et al, 2014).…”

Bruchidius coreanus is a serious pest on Gleditsia sinensis Lam during seed storage, causing significant losses to their yield in southwest China. To gain insight into their behavioral mechanisms, the external morphology, ultrastructure, and distribution of sensilla on antennae, maxillary palps, and labial palps of both male and female B. coreanus were observed using a scanning electron microscope. The results revealed that both male and female adults had serrated antennae comprising a scape, a pedicel, and nine flagellomeres (F1–F9). There were eight types and seven subtypes of antenna sensilla observed in both sexes, including Böhm sensilla (BS), two subtypes of sensilla chaetica (SC1 and SC2), two subtypes of sensilla trichodea (ST1 and ST2), three subtypes of sensilla basiconica (SB1, SB2, and SB3), sensilla auricillica (SA), sensilla styloconicum (SS), capitate pegs (CP), and sensilla cavity (SCa). The average length of BS and ST (ST1 and ST2) showed significant differences between males and females. Furthermore, the number of SC (SC1 and SC2), ST1, and SCa differed significantly between the sexes. Four types of sensilla were found on the maxillary palps and labial palps, with the length of ST on these palps significantly differing between males and females. Additionally, SS on male labial palps was significantly longer than in females. The number of SC significantly differed between the male and female maxillary palps and labial palps, while ST and SS showed significant differences in the maxillary palps. These findings will contribute to further electrophysiological recording and behavioral research.Research Highlights The external morphology and distribution of various sensilla on the antennae, maxillary palps, and labial palps of Bruchidius coreanus were described. Eight types and seven subtypes of antenna sensilla were observed on the antennae, while four types of sensilla were observed on the maxillary palps and labial palps. The capitate pegs were found exclusively on the antennae of female B. coreanus.

“…The insects were gradually dehydrated using a series of ethanol concentrations (80%, 90%, 95%, and 100% [v/v]) to avoid distorting the samples. The waxy layer that affects the investigation process of fine structures, such as sensilla, was removed using a modified method by Sirisena et al [ 28 ] by soaking the samples for 10 min with hexane instead of chloroform [ 38 ]. Finally, the samples were rinsed in 100% ethanol to ensure complete removal of water, and oriented and mounted on aluminum stubs with double-sided sticky tape.…”

Background The cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is one of the most devastating sap-sucking pests of cultivated plants. The success of P. solenopsis is attributable to its ecological resilience and insecticide resistance, making its control extremely difficult and expensive. Thus, alternative safe approaches are needed to prevent the pest population from reaching the economic threshold. One of these novel approaches is based on the fact that chemical communication via the olfactory system drives critical behaviors required for the survival and development of the species. This knowledge can be useful for controlling insect pests using traps based on semiochemicals. The antennae of insects are an invaluable model for studying the fundamentals of odor perception. Several efforts have been made to investigate the histological and ultrastructural organization of the olfactory organs, such as the antennae and maxillary palps, in many insect species. However, studies on the antennal sensory structures of Phenacoccus species are lacking. Furthermore, although enormous progress has been made in understanding the antennal structures of many mealybug species, the olfactory sensilla in the antennae of P. solenopsis have not yet been described. In this study, we describe, for the first time, the morphology and distribution of the antennal sensilla in male and female P. solenopsis using scanning electron microscopy. Results Our results revealed that the entire antennae length and the number of flagellar segments were different between the sexes. Eight morphological types of sensilla were identified on male antennae: trichoid sensilla, chaetic sensilla (three subtypes), basiconic sensilla (two subtypes), and campaniform sensilla (two subtypes). Six morphological types of sensilla were found on female antennae. Sensilla chaetica of subtype 2 and campaniform sensilla of subtype 1 were distributed only on male antennae, suggesting that these sensilla are involved in the recognition of female sex pheromones. The subtype 1 of sensilla chaetica was significantly more abundant on female antennae than on male ones, while subtype 3 was only located on the terminal flagellar segment of the antenna in both sexes. Conclusions This study provides insightful information for future electrophysiological and behavioral studies on chemical communication in insects, particularly the cotton mealybug, P. solenopsis that could help in developing new strategies for controlling this economically important insect species.
