Morphology of antennal sensilla and their distributions were investigated in male and female adults of two tortricid moths, Cydia pomonella and C. succedana using scanning electron microscopy. The antennae of both sexes of the two species were filiform, and the overall lengths of the antennae and the number of consisting segments were greater in males than in females. Six types of sensilla (s.) were identified from the antennae of both sexes in the two species: s. trichodea, s. basiconica, s. coeloconica, s. auricillica, s. chaetica, and s. styloconica, in varying numbers and distribution along the antennae. Among them, surface of four sensilla types (s. trichodea, s. basiconica, s. coeloconica, s. auricillica) were multiporous in the two species, indicating that the primary function of these sensilla is olfactory. The s. trichodea were the most numerous on the antennae in both sexes of the two species. Male C. pomonella has a greater number of s. trichodea than the female. The four sensilla types were further divided into different subtypes in the two species; s. trichodea into three subtypes, s. basiconica into two subtypes, s. coeloconica into two subtypes in C. pomonella and one subtype in C. succedana, and s. auricillica into two subtypes. Sexual dimorphism was observed in the subtypes of s. trichodea. The long subtype of s. trichodea occurs only on male antennae, whereas the short subtypes mainly on female antennae. These findings would be helpful for further studies on detailed chemo-receptive functions of each subtype of the antennal sensilla.

“…Hence, other antennal sensilla must exist which are stimulated by plant odours. Possible candidates are sensilla coeloconica, sensilla auricillica, sensilla styloconica, and sensilla chaetica type II Van der Pers et al, 1980). It has been found that females of Yponomeuta and A. orana are at least tenfold less sensitive to sex attractants than conspecific males Van der Pers and Den Otter, 1978).…”

“…The pipette was then attached to a micromanipulator. The antenna was positioned in such a way that its scaleless side (Van der Pers et al, 1980) faced the stim-ulus Source. A second saline-filled pipette serving as indifferent electrode was placed over the distal end of the antenna.…”

Electroantennogram responses (EAGs) from seven Yponomeuta species and from Adoxophyes orana were recorded during stimulation with 57 plant volatiles and leaf extracts from six host plants. Cluster analysis was applied to determine whether any grouping occurred of the response spectra of the antennae and of the response profiles to the plant volatiles. In the dendrogram of the response spectra four clusters of species groups could be distinguished. No conclusions about the taxonomic relationships were drawn from this dendrogram because of the relatively high similarity between the response spectra of the Yponomeuta species and A. orana. This similarity can be explained by these moths having food plants in common. From the response profile dendrogram no conclusions could be drawn about the number and nature of physiologically different types of olfactory cells. The leaf extracts did not evoke significantly different responses among the Yponomeuta species and A. orana. Obviously, differences in the composition of the extracts were not expressed in the EAG. The EAG responses to plant volatiles did not differ essentially between male and female moths suggesting that both sexes were equally able in detecting host plants. RÉSUMÉ Comparaison des électroantennogrammes de sept espèces d'Yponomeutes et d'Adoxophyes orana à des substances volatiles végétales Les électroantennogrammes d'Yponomeuta (7 espèces) et d'Adoxophyes orana ont été enregistrés pendant la stimulation avec 57 substances volatiles et extraits foliaires de 6 plantes‐hôtes. L'analyse de la distribution a été utilisée pour déterminer si les spectres de réponses de l'antenne et les réponses aux substances volatiles présentaient un aspect contagieux. On peut distinguer 4 groupes d'espèces dans le dendrogramma des réponses. Aucune relation taxonomique ne peut être tirée de ce dendrogramme par suite de la relativement haute similarité entre les spectres des réponses des Yponomeuta et de A. orana. Cette similarité peut s'expliquer par l'identité des plantes hôtes de ces espèces. Aucune conclusion ne peut être tirée du profil des dendrogrammes sur le nombre et la nature des différents types de cellules olfactives. Les extraits de feuiles ne provoquent pas de différences significatives dans les réponses d'Yponomeuta et A. orana, les différences dans la composition des extraits n'apparaissent pas dans les AEG. Il n'y a pas de différences entre les AEG des deux sexes aux substances volatiles, ce qui laisse supposer qu'ils sont capables, tous les deux, de détecter les plantes‐hôtes.

The antennal flagellum of female Manduca sexta bears eight sensillum types: two trichoid, two basiconic, one auriculate, two coeloconic, and one styliform complex sensilla. The first type of trichoid sensillum averages 34 μm in length and is innervated by two sensory cells. The second type averages 26 μm in length and is innervated by either one or three sensory cells. The first type of basiconic sensillum averages 22 μm in length, while the second type averages 15 μm in length. Both types are innervated by three bipolar sensory cells. The auriculate sensillum averages 4 μm in length and is innervated by two bipolar sensory cells. The coeloconic type-A and type-B both average 2 μm in length. The former type is innervated by five bipolar sensory cells, while the latter type, by three bipolar sensory cells. The styliform complex sensillum occurs singly on each annulus and averages 38-40 μm in length. It is formed by several contiguous sensilla. Each unit is innervated by three bipolar sensory cells. A total of 2,216 sensilla were found on a single annulus (annulus 21) of the flagellum. Electrophysiological responses from type-A trichoid sensilla to a large panel of volatile odorants revealed three different subsets of olfactory receptor cells (ORCs). Two subsets responded strongly to only a narrow range of odorants, while the third responded strongly to a broad range of odorants. Anterograde labeling of ORCs from type-A trichoid sensilla revealed that their axons projected mainly to two large female glomeruli of the antennal lobe.
