“…The distribution and types of antennal sensilla of E. ferrugineus are similar to what has been described in other genera and species of Elateridae: A. obscurus (Merivee et al 1997), L. aeruginosus (Merivee et al 1998), M. villosus (Merivee et al 1999), M. cribricollis (Guandi et al 2012) and T. lewisi (Ren et al 2014).…”

“…Similar sensilla were described as s.t.2, and found in high numbers on the male antenna of M. villosus, indicating that they are probably responsible for the detection of pheromones at long distance (Merivee et al 1999). Comparable sensilla were analysed by TEM and described as tr.2 on the antenna of T. lewisi, with a thick wall and a low density of wall pores (Ren et al 2014). In this species tr.2 were assumed to be contact pheromone receptors, being more abundant in females than males.…”

“…In previous studies it has been demonstrated: (1) the first chemoreceptor neuron responds to various salts (Merivee et al 2004); (2) the second one is sensitive to pH (Merivee et al 2005;Milius et al 2006); (3) the third one responds to various plant and aphid honeydew sugars and amino acids (Merivee et al 2007(Merivee et al , 2008; (4) the fourth neuron responds to plant alkaloids and glucosides (Milius et al 2011); (5) the fifth one responds to bending of the hair (Merivee et al 2008). In other Elateridae, sensilla Tr.1 of E. ferrugineus share similar morphological characteristics to sensilla Tr.1 of A. obscurus (Merivee et al 1997;Tooming et al 2012), T1 of L. aeruginosus (Merivee et al 1998), T1 of M. villosus (Merivee et al 1999) and Tr.1 of T. lewisi (Ren et al 2014). The ultrastructure of these sensilla was described for T. lewisi as having thick cuticular walls.…”

“…We followed the terminology and classification reported in other papers on antennal sensilla of Coleoptera Elateridae (Merivee et al 1997(Merivee et al , 1998(Merivee et al , 1999Ren et al 2014). For the orientation of the antenna we referred to Merivee et al (1997).…”

“…These studies are the prerequisite for any electrophysiological research and can suggest possible functions of sensilla by their morphology, number, distribution, and presence or absence on the antennae of the two sexes. For another click beetle, Tetrigus lewisi, both antennal fine morphology (by SEM) and sensilla ultrastructure (by transmission electron microscopy, TEM) have been described (Ren et al 2014). In this case, the study of the fine structure of sensilla, and of the associated neuron dendrites, made it possible to deduce their different functions as chemoreceptors, mechanoreceptors, thermoreceptors and hygroreceptors.…”

This work provides the first morphological analysis (both at gross and fine level) of the antennal structures in the genus Elater (Coleoptera, Elateridae). The typology, number and distribution patterns of the antennal sensilla in the rare saproxylic Elater ferrugineus (both male and female) were studied using scanning electron microscopy (SEM). The serrate antennae of E. ferrugineus consisted of a scape, a pedicel, and nine flattened flagellomeres. Overall, 10 types of sensilla were identified according to their morphological features: one type of sensilla chaetica (Ch), one type of Böhm sensilla (Bo), three types of sensilla trichodea (Tr.1-3), two types of sensilla basiconica (Ba.1-2), one type of sensilla styloconica (St), one type of grooved peg sensilla (Gp) and one type of sensilla campaniformia (Ca). A marked sexual dimorphism was found at both gross and fine scale. The male antenna was bigger (8.6 mm) than the female one (7.0 mm) and carried one type of sensilla trichodea (Tr.2) absent in female antennae possibly responsible for reception of the female-emitted sex pheromone. The female antenna carried a higher number of sensilla (~9800) than the male one did (~7,000), with more abundant sensilla chaetica (Ch) and basiconica (Ba.1 and Ba.2).

Eogystia hippophaecolus (Hua et al.) is an important boring pest that primarily damages sea buckthorn, causing large ecological and economic damages in China. In this study, we used scanning electron microscopy to investigate the sensilla on six olfactory tissues of male E. hippophaecolus: antennae, labial palps, external genitals, propodeum, mesopodium, and metapedes. On the antennae, two types of sensillum trichodea, two types of sensillum basiconica, a type of sensillum coeloconica, and Böhm's bristles were found. The labial palps had sensilla trichodea and chaetica. On the external genitals, three types of sensilla trichodea were the only sensilla. Böhm bristles were found on the base of the tibia and at the terminus of the tarsus. Most sensilla were distributed on the tarsus of the three pairs of legs, and notably, a majority of which were sensilla trichodea and sensilla chaetica, were on the pretarsus and telotarsus of the three pairs of legs. In this study, the distribution, number, type, and morphology of the sensilla on six olfactory organs of E. hippophaecolus were determined, which established the foundation for a future immunohistochemical search of olfactory proteins. Research highlights Eogystia hippophaecolus is a serious pest of seabuckthorn. The distribution, number, type, and morphology of olfactory sensilla of E. hippophaecolus are determined. The function and distribution of sensilla are compared with those of other insects.

This study used scanning electron microscopy (SEM) to observe the morphology and sensilla of the labial and maxillary palps of adult Callidiellum villosulum Fairmaire between sexes. Combining behavioral activities may provide an effective control target for this pest. In this study, the results showed that there were three segments on the labial palps and four segments on the maxillary palps. The length and width of each segment of the labial and maxillary palps were significantly larger in females than in males. Four types of sensilla were found on the labial and maxillary palps of both sexes of adult C. villosulum: sensilla basiconica (SB I, II, III, and IV), sensilla chaetica (SCh I and II), sensilla placodea (SP), and sensilla campaniformia (SCa). SB IV, SCa, and Sh II were significantly more developed on female labial and maxillary palps than on males', which may be related to their oviposition behavior. By contrast, SB I was more significantly developed on males than on females, which may be related to their mating selection. At the same time, for both sexes, the numbers of Sh I and Sh II on the maxillary palps were significantly higher on labial palps. Maxillary palps could be inferred to potentially play a more important role than the labial palps in the activities of adult C. villosulum. Results will help us further understand the host selection and egg‐laying behavior of adult C. villosulum. Such an understanding shall greatly promote the information‐based design of pest control methods.
