“…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 subtypes of sensilla basiconica observed in A. chalybaeus were also described in other coleopterans such as C. aeruginosa Fald (Zhang et al, 2013), Hippodamia variegate (Hao et al, 2020), Harmonia axyridis Pallas (Chi et al, 2009), Phoracantha semipunctata Fabricius (Lopes et al, 2002), Emphorini bees (Galvani et al, 2012), Agriotes (Faucheux et al, 2020), H. axyridis (Sevarika et al, 2020), Arma chinensis (Zhang et al, 2014), and Ulomoides dermestoides (Qian et al, 2018). All the subtypes of sensilla basiconica of A. chalybaeus share typical structural features of insect chemosensory sensilla, such as inflexible sockets, thin multiporous cuticular wall, or a tip pore (Zacharuk & Shields, 1991).…”

Aplosonyx chalybaeus is a major insect pest of the plant Colocasia which is commonly found in the North-Eastern region of India. The antenna of A. chalybaeus is filiform, composed of a scape, a pedicel, and a flagellum with nine flagellomeres. The type, structure, and distribution of sensilla, on the antennae of the adult A. chalybaeus (Coleoptera: Chrysomelidae), were examined by scanning electron microscopy. Eight different types of sensilla were observed on the antennae using scanning electron microscopy, that is, sensilla trichodea, sensilla chaetica, sensilla basiconica, multiporous grooved pegs, sensilla auricillica, sensilla styloconica, glandular plates, and Böhm sensilla based on their external morphology. Distribution of all the antennal sensilla observed was discussed on the antenna. In addition, we discussed the putative functions of all the sensilla observed based on their external morphological and distributional characteristics on the antenna of the species. Research Highlights• External morphology and distribution of various antennal sensilla in male and female of Aplosonyx chalybaeus were described.• Eight types with 17 subtypes of antennal sensilla were observed.• Distinct sexual dimorphism was observed in occurrence and distribution of various sensilla.

The antennal sensilla play an important role in many behavioral activities of insects. The fungivorous beetle Triplax ainonia Lewis (Erotylidae) is an important pest which prefers to feed on Pleurotus mushrooms. In order to clarify the types, number, and distribution of the antennal sensilla of male and female T. ainonia, scanning electron microscopy was used. The results showed that there were five sensillum types on the antennae of adults male and female, including Böhm’s bristles (BB), sensilla chaetica (three subtypes: SC 1, SC 2, and SC 3), sensilla basiconica (three subtypes: SB 1, SB 2, and SB 3), sensilla trichodea (ST), and sensilla styloconica (SS). Among all the sensilla, the number of SB 2 was the most abundant in both sexes. We found that there was no sexually dimorphic in the sensillum types, but there were differences in the number, lengths, and diameters of some sensilla between males and females. Based on the information of the morphology and distribution of the sensilla, the potential functions of the antennal sensilla of T. ainonia adults were discussed. The results of this study provide a basis for further study on the behavioral ecology and electrophysiology of the fungivore beetles of the Erotylidae.
