“…Eucerini and Emphorini species showed conspicuous rows of dorsal setae in the distal zone. The segregation in the dorsal distribution of sensilla was already observed in bees of Colletidae, Andrenidae, Halictidae, and Apidae (Ågren 1977, 1978Ågren and Svensson, 1982;Galvani et al 2012; Fig. 7 Densities in multiporous, uniporous and nonporous sensilla on F10 of females of Apidae.…”

“…Densities of sensilla were calculated by setting a rectangular area on the dorsal side of each 438 G.L. Galvani et al flagellomere; this area was limited by the entire length of the segment (the X -axis), while the Y-axis was half the length of each flagellomere (Galvani et al 2012). Those types of sensilla with less than four counts per flagellomere as well as pit organs were excluded from the study.…”

“…In order to confirm the functional sensory type (multi-, uni-, or nonporous sensilla), the internal structure of the subtypes of sensilla trichodea and setae was analyzed. Sensilla placodea and basiconica were described by taking into account only the external morphology (Galvani et al 2012). To assign a functional role to each type, previous reports were considered (Slifer and Sekhon 1961;Whitehead and Larsen 1976).…”

-In bees, most of the comparative studies linking the sensory system and behavior were performed in social species. Here, we describe the morphology of antennal sensilla in solitary and cleptoparasitic bees of Apinae and Nomadinae. The external and internal structure of sensilla and setae as well as their distribution in flagella were studied in detail in two different host-cleptoparasitic associations. In addition, taking into account the presence of pores, the distribution of sensilla was compared in females and males of 39 species of these subfamilies. It was found that males of non-parasitic bees showed a higher number of multiporous sensilla. Females had more uniporous and nonporous sensilla than males. Cleptoparasitic bees showed a low diversity in types of sensilla and no sexual dimorphism in number. The pattern of sensilla in males and their cleptoparasitic females was discussed in the context of their ecological roles.antennal morphology / sensilla ultrastructure / olfaction / dimorphism

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.

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.
