“…Because the apical organs would be exposed directly to the airflow as chemoreceptors, the location of these organs in relation to antennal position during flight would allow for the concentration of odour stimuli within the lumen of the slit. The efficiency of odour detection by sensilla basiconica within the slit would appear to be increased, as the probability of an odour molecule striking a sense hair would also be increased, as odours are concentrated within the slit (Scott & Garra, 1975).…”

The "jewel beetle" -Belionota prasina (Thunberg, 1789), is a polyphagous insect pest found throughout India and its neighboring countries. To develop semiochemical-based pest control strategies, we must first comprehend the entire morphological features of the insect's antennal sensory structure. This is the first study report revealing the morphology and ultrastructure of antennal sensillae of male and female of B. prasine using light and scanning electron microscopy. Both antennae are serrated in appearance with 11 antennomers. In both sexes, Böhm sensilla, sensilla trichodea, sensilla basiconica, sensilla chaetica, and multiporous grooved peg sensilla are common. Sexual dimorphism is present in the case of length and width (basal and distal) of entire antenna as well as each antennomer. Male antennomeres are larger and more robust. The antenna of B. prasina shows a high degree of sexual dimorphism. The C4 type aporous serrated sensilla chaetica, which serves a tactile function, are highly specific to male antennae. The sensilla basiconica subtype 4 is found in female antennomeres while multigrooved are pegs present only in male antennomerers. The number and type of sensillae are greater in males than females. Apical fossae are present dorsally and ventrally on each male antennomere. The function and distribution of all types of sensilla are explained and illustrated in this paper.

“…Although the jewel beetles (Buprestidae) are a large beetle family that contains also economically significant species, publications about the structure and morphology of antennal sensilla are relatively rare (Scott and Gara 1975;Volkovitsh 2001;Crook et al 2008;Yi et al 2016;Bari et al 2019;Faucheux et al 2020). In most papers, the external morphology of the sensilla is described by SEM; only in one paper additional TEM micrographs are presented revealing the innervation pattern (Crook et al 2008).…”

Sensory equipment and adaptations to the fire habitat of the antennae of the Australian ´firebeetle´ Merimna atrata (Coleoptera; Buprestidae)

The ‘Australian firebeetle’ Merimna atrata approaches fires in Eucalyptus forests for reproduction. Beetles stay on a postfire area as long as burning wood or hot ashes emit heat and smoke. Abdominal infrared receptors protect the beetles from landing on hot spots; however, until now fire-specific adaptations of the antennae have not been investigated in more detail. This affects the localization of olfactory sensilla used for the perception of smoke and in addition mechanisms to protect delicate sensilla against desiccation and pollution. Moreover, nothing was known about antennal thermo-/hygroreceptors in Merimna atrata. We found strong evidence for a functional grouping of the sensilla into receptors used on the ground or in flight, respectively. A first group comprises the outer visible sensilla, i.e. mechanosensory bristles, short gustatory sensilla and a small field of very short olfactory sensilla. They are used when the beetle is running around on the fireground on burnt bark or ashes. A second group of sensilla is hidden in closeable cavities on antennomeres 4–11. If the cavities are closed, the sensilla inside are fully protected. If the cavities are opened in flight, the beetles can make use of many multiporous basiconic sensilla and multiporous basiconic grooved peg sensilla for smoke detection. Minute modified sensilla coelocapitula occurring in small numbers in the cavities too, most probably serve as thermoreceptors. As a result the placing of sensilla deserving protection in closeable cavities and the reduction in number and length of the external sensilla can be interpreted as adaptations to the fire habitat.

“…Indeed, antennae of these insects have numerous sensory structures called sensilla, where volatiles can be recognized by odorant binding proteins (OBPs), and subsequent signal transduction can lead to the ultimate perception of quality and quantity of odors in the brain ( Zacharuk 1980 , Pitts and Zwiebel 2006 ). It was found that the morphology and ultrastructure of anetennal sensilla could be extremely variable among different species of beetles ( Scott and Gara 1975 ; Merivee et al 1998 , 1999, 2002 ; Volkovitsh 2001 ; Crook et al 2008 ; Ren et al 2014 ). However, a few studies have documented antennal sensilla of beetles (e.g., Melanophila sp.)…”

The apple buprestid beetle, Agrilus mali Matsumura, is an invasive pest causing significant damages to rare wild apple forests of Xinjiang. The morphology, abundance and distribution of antennal sensilla in both sexes of this pest were examined. We found that the antennae of A. mali females were longer than those of males. Five types of antennal sensilla were characterized, including trichodea (subtypes Tr.1, Tr.2, and Tr.3), chaetica (subtypes Sc.1, Sc.2, Sc.3, and Sc.4), basiconica (subtypes Ba. 1, Ba. 2, Ba. 3 and Ba.4), Böhm bristles (subtypes BB. 1, and BB. 2), and multiporous grooved sensilla. The most abundant sensilla of Ba.2 tended to occur mainly on flagellomeres 5–8 in both sexes. The last three flagellomeres tended to have the most abundant Tr.1 in both sexes. Overall, the abundance and distribution of these sensilla appeared to be highly conserved in both sexes, and their olfactory organs seemed to cluster on flagellomeres 6–8. However, some sex dimorphisms were also observed. Tr.3 and BB.2 were found only in females. Sensilla of Sc.2 were found on the pedicel and first two flagellomeres only in males. When compared with males, females showed a higher number of Sc.3, but a lower number of Sc.4 on the pedicel. These results indicate that contact cues could be important in intersexual communication in A. mali. The functional roles of these sensilla and their implications in A. mali behaviors are discussed, and further studies of identified chemosensitive sensilla can provide a foundation for developing semiochemical-based management strategies.
