“…However, the thickness of the cuticular wall was clearly different between the “thick‐walled” trichoid sensilla and the “thin‐walled” basiconic sensilla in the antennae of B. depressa , which appears to be in accordance with the observations in other groups of insects. For example, the single‐walled basiconic sensilla on the antennae of a fly, Ceratitis capitata (Tephritidae), were thin‐walled (Mayo, Anderson, Burguete, & Chillida, ), whereas the antennal trichoid sensilla in a beetle Tribolium castaneum (Tenebrionidae) were thick‐walled (Ali, Diakite, Ali, & Wang, ). It is not yet clear if this correlation is consistent across a wide range of insect species.…”

The morphology and ultrastructure of the olfactory sensilla on the antennae and maxillary palps were investigated through scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and their responses to five volatile compounds were measured using electroantenogram (EAG) and electropalpogram (EPG) techniques in the pumpkin fruit fly, Bactrocera depressa (Shiraki; Diptera: Tephritidae). Male and female B. depressa displayed distinct morphological types of olfactory sensilla in the antennae and maxillary palps, with predominant populations of trichoid, basiconic, and coeloconic sensilla. Basiconic sensilla, the most abundant type of olfactory sensilla in the antennae, could be further classified into two different types. In contrast, the maxillary palps exhibited predominant populations of a single type of curved basiconic sensilla. High‐resolution SEM observation revealed the presence of multiple nanoscale wall‐pores on the cuticular surface of trichoid and basiconic sensilla, indicating that their primary function is olfactory. In contrast, coeloconic sensilla displayed several longitudinal grooves around the sensillum peg. The TEM observation of individual antennal olfactory sensilla indicates that the basiconic sensilla are thin‐walled, while the trichoid sensilla are thick‐walled. The profile of EAG responses of male B. depressa was different from their EPG response profile, indicating that the olfactory function of maxillary palps is different from that of antennae in this species. The structural and functional variation in the olfactory sensilla between antennae and maxillary palps suggests that each plays an independent role in the perception of olfactory signals in B. depressa.

“…Red flour beetles may use the sensilla basiconica to detect sex pheromones, possibly in conjunction with host plant odors, as great numbers of sensilla can indicate high sensitivity levels (Chapman, 1998). In addition, the sensilla basiconica on the last 3 segments of the club might play a major role in the food source location behavior of T. castaneum (Ali et al, 2016). Accordingly, we recorded changes in the sensilla basiconica morphology in adult antennae after pupal UV-C radiation, and interestingly, the sensilla basiconica subtypes (sb1 and sb2) had a wider shape than the controls.…”

“…This study revealed a decrease in the number and length of several types of sensilla after UV-C radiation. In T. castaneum, the sensilla trichodea are responsible for the olfactory detection of host plants and mating sites (Ali et al, 2016). We found that the number and length of the st1 and st2 subtypes on the club, scape, and pedicel were reduced in the adults that were irradiated with UV-C during the pupal stage.…”

The present study reveals the effects of ultraviolet-C on the morphology of the antenna and antennal sensilla of Tribolium castaneum. Pupae were irradiated with UV-C at a distance of 35 cm for 1, 2, 4, 8, 16, 32, or 64 min. The morphometric traits of the antenna and antennal sensilla were determined using light and scanning electron microscopy. UV-C caused abnormalities to the adults' antennae that were classified into 3 levels; mildly, moderately and strongly affected. A loss of segmentation occurred in the funicle and club, and the antennae were greatly reduced in size overall. The severity of the antennal abnormalities occurred in a dosedependent manner. The UV-C radiation significantly decreased the length of the scape, funicle, and club and the width of the club. Scanning electron microscopy of the resulting adults showed the antennae had a wrinkled cuticle, and the sensilla were fewer in number. The long sensilla trichodea became shorter, while the long and short sensilla trichodea were broader. Likewise, the width of sensilla basiconica subtypes 1 and 2 also increased after the UV-C irradiation. The results indicate that UV-C irradiation causes specific malformations in the antennae and antennal sensilla of T. castaneum.

“…Even fewer studies analyze the internal structure and innervation of the sensilla (Moeck, 1967). Several studies deal with the involvement of the antennal sensory system in interspecies communication and behavioral responses in Coleoptera (Lopes, Marques & Araújo, 2005;Ali et al, 2016).…”

Miniaturization is a major evolutionary trend prominent in insects, which has resulted in the existence of insects comparable in size to some unicellular protists. The adaptation of the complex antennal multisensory systems to extreme miniaturization is a fascinating problem, which remains almost unexplored. We studied the antennal sensilla of Scydosella musawasensis Hall, 1999 (Coleoptera: Ptiliidae), the smallest free-living insect, using scanning electron microscopy. The antenna of S. musawasensis bears 131 sensilla; no intraspecific variation in the number or position of the sensilla has been revealed. Nine different morphological types of sensilla are described according to their external morphological features and distribution: four types of sensilla trichodea, one type of sensilla chaetica, two types of sensilla styloconica, and two types of sensilla basiconica. Morphometric analysis of the sensilla of S. musawasensis, based on measurements of the lengths and diameters of sensilla and their location and number, showed the absence of significant differences between females and males. Comparative allometric analysis of S. musawasensis and larger Coleoptera showed that the number of sensilla and the size of sensilla chaetica decrease with decreasing body size. However, the number of the types of sensilla and the length and diameter of the multiporous sensilla basiconica revealed no correlation with the body size. Comparison of the acquired data with the results of our earlier study of the antennal sensilla of some of the smallest parasitic wasps is used to put forward hypotheses on the common principles of miniaturization of the antennal sensory systems of insects.
