“…The Tephritidae are, together with the Drosophilidae, members of the Acalyptrata subsection of Brachyceran Diptera, and scanning electron microscopy (SEM) has revealed a spatial distribution of olfactory sensilla on the funiculus surface for C . capitata 37 , Anastrepha fraterculus 38 , and species in the Dacini tribe 32 , 39 – 41 that is roughly similar to the one observed in Drosophila . EAG signals were found to vary with the relative density of sensilla at the electrode location in C .…”

Ecological specialization of insects involves the functional and morphological reshaping of olfactory systems. Little is known about the degree to which insect sensitivity to odorant compounds is conserved between genera, tribes, or families. Here we compared the olfactory systems of six tephritid fruit fly species spanning two tribes and the distantly related Drosophila melanogaster at molecular, functional, and morphological levels. Olfaction in these flies is mediated by a set of olfactory receptors (ORs) expressed in different functional classes of neurons located in distinct antennal regions. We performed a phylogenetic analysis that revealed both family-specific OR genes and putative orthologous OR genes between tephritids and Drosophila. With respect to function, we then used a current source density (CSD) analysis to map activity across antennae. Functional maps mirrored the intrinsic structure of antennae observed with scanning electron microscopy. Together, the results revealed partial conservation of the olfactory systems between tephritids and Drosophila. We also demonstrate that the mapping of olfactory responses is necessary to decipher antennal sensory selectivity to olfactory compounds. CSD analysis can be easily applied to map antennae of other species and therefore enables the rapid deriving of olfactory maps and the reconstructing of the target organisms’ history of evolution.

“…In spite of their abundance, only three subtypes were distinguished. The sensilla styloconica are well studied and several functions have been assigned to them in different insects: mechano‐, chemo‐, hygro‐, and/or thermoreceptors (Bissoto de Oliviera, Redaelli, & Santana, 2011; Schneider, 1964; Shields, 2009; Steinbrecht, 1998; Zacharuk, 1985). In aquatic insects sensilla styloconica are reported mainly as chemosensory organs, although little information is available (Gaino & Rebora, 1999).…”

Larvae of the burrowing water beetle family Noteridae are distributed worldwide and are often abundant in a broad range of aquatic habitats, playing an important role in structuring freshwater communities, yet they have remained among the most poorly studied groups of aquatic beetles. Studies on sensillar equipment of aquatic insect larvae are largely lacking, despite their potential use in phylogeny and biometric identification methods. In this article, the external morphology and distribution of sensilla on the head appendages of first instar larvae of selected genera of Noteridae were examined using scanning electron microscopy. Seven main types were distinguished based on their morphological structure: basiconica (3 subtypes), campaniformia (2 subtypes), chaetica (7 subtypes), coeloconica (6 subtypes), coniform complex (2 subtypes), placodea, and styloconica (3 subtypes). The apex of the labial palpus was found to be the most variable and informative region in regard to the number, relative position, and topology of sensilla. Fingerprint models were, therefore, generated for this region in each of the studied genera, allowing their identification.

“…Such detection of chemicals external is now recognized as olfaction and gustation. Numerous studies indicated that it is the sensilla on the bodies of insects that detect taste and smell in the environment (Bisotto‐de‐Oliveira et al,2011; Hill et al,2009; Nakanishi et al,2009). Sensilla grow on the surface of nearly all external organs of an insect, such as the antenna, maxillary palp, tarsus, and generative organs (Rice et al,1973; Smallegange et al,2008; Spanhoff et al,2003; Spiegel et al,2005; Sukontason et al,2007).…”

In this article, we described the ultrastructure of the sensilla on the antenna, eyes, mouthparts, wings, legs, and external genitalia of female and male Trichogramma dendrolimi using scanning electron microscopy (SEM). The antenna possessed the most sensilla types. We found 13 types of sensilla on female antenna, which were trichoid sensilla (TS) type 1-4, chaetica sensilla (ChS) type 1-2, campaniform sensilla (CaS), falcate sensilla, placoid sensilla (PS) type 1-2, basiconic capitate peg sensilla (BCPS) type 1, coeloconic sensilla (CoS), and styloconic sensilla. Ten types of sensilla were found on the male antenna, some were the same as that on female T. dendrolimi antenna, such as TS types 1 and 3, CaS, PS type 1, BCPS type 1, and CoS, but TS types 5 and 6, ChS type 3, and BCPS 2 were specific to male T. dendrolimi antenna. The leg possesses eight types of sensilla and a kind of tympana structure. Four types of TSs were found on the wings. On the mouthparts, sensilla on the maxillary and labial palps were unique, including two TSs and one ChS. The ovipositor possesses three types of sensilla, and the copulatory organ possesses two types. The eyes had only one kind of TS. Furthermore, external morphology of antenna and external genitalia revealed distinct sexual dimorphisms. According to their morphology, the possible functions of these sensilla were discussed. These results may further our understanding of the sensory mechanisms of T. dendrolimi in response to infochemicals within the environment.
