“…The s. chaetica type I closely resemble the similarly named in Yponomeuta (VAN DER PERS et al 1980;CUPERUS et al 1983;CUPERUS 1983) in having a distinct socket and a terminal pore. Such sensilla where shown to be sensitive to mechanical stimulation (VAN DER PERS and DEN OTTER 1978) and assumed to have contact-chemoreceptive function in addition (VAN DER PERS et al 1980).…”

“…Studies on insect sensilla predominantly concentrate on functional morphology and physiology, and recently resulted in an accumulation of knowledge on ultrastructure and function (reviews: ALTNER 1977; ALTNER and PRILLINGER 1980;SLIFER 1970;ZACHARUK 1980). Studies on comparative morphology on antenna1 sensilla and the importance of these structures in phylogenetic reasoning are few and comprise studies on Coleoptera-Lamellicornia (MEINECKE 1975) and Hymenoptera-Aculeata (WALTHER 1979 DS FAUCHEUX 1979FAUCHEUX 1982a, b, 1984CUPERUS 1983, C. et al 1983FAUCHEUX 1978bWALL 1978ALBERT and SEABROOK 1972DEN O~E R et al 1978SUBCHEV 1977aSELLIER 1977CORNFORD et al 1973CALLAHAN 1973SELLIER 1974MYERS 1968SUBCHEV 1977bSCHNEIDER STEINBRECHT 1973FAUCHEUX 1978aBOECKH et al 1960FAUCHEUX 1978aKEIL 1984FAUCHEUX 1978aJEFFERSON et al 1970FLOWER and HELSON 1974 For sound conclusions with regard to the evolution of these organs, it is of paramount importance to know the antennal morphology of the groups right at the basis of the cladogram of the Lepidoptera. Fortunately, many data on antennal sensilla of primitive Lepidoptera are found in the detailed taxonomic and morphological treatments by NIELSEN, KRISTENSEN and DAVIS o n various families of non-Ditrysia.…”

Antennae of representatives of most genera and subgenera of Nepticulidae have been examined in detail with SEM. Flagellar segments are highly uniform and possess each 1–3 s. trichodea, 1–3 long s. chaetica type I, 12 short s. chaetica type II and 0–2 s. coeloconica of a simpified type without “picket fence”. The dominating structure is a pair of s. vesiculoclada, a unique sensillum type, believed to be a synapomorphy for the Nepticulidae. A pair is present on alt flagellomeres in male antennae but not on all flagellomeres of females in two subgenera of Ectoedemia. Principally each s. vesiculocladum is five‐branched, with the branches joined tightly to the flagellar cuticle, but reduction of the branches occurs in several genera, in particular in Ectoedemia. This sensillum can be classified as a single‐walled wp sensillum, and thus a chemoreceptor. The s. vesiculocladum is considered to be a homologue of the ascoid sensilla in the Opostegidae. The presence of these special setae is considered as an additional synapomorphy for both families. A review of previous Literature on lepidopteran sensilla is presented and the present data are compared and discussed. In the Nepticulidae the s. vesiculocladum is assumed to be the major pheromone detector in contrast to the s. trichodea of most other Lepidoptera.

“…The antenna of the male RBLR bears all the usual morphological types of sensilla commonly found in moths (Albert & Seabrook, 1973;Cuperus, 1983Cuperus, , 1985Cuperus et al, 1983; George & Nagy, 1984; Wall, 1978). The shorter sensilla appear to be much less abundant than the long, recurved trichoids (Fig.…”

Response specificity of male olfactory receptor neurones for the major and minor components of a female pheromone blend

The sex attractant of the female redbanded leafroller moth, Argyrotaenia velutinana (Walker), is a blend of seven compounds. Specialized olfactory receptor neurones had been found for only two of the compounds, (Z)‐11‐tetradecenyl acetate (Z11‐14:Ac) and (E)‐11‐tetradecenyl acetate (E11–14:Ac). These receptor neurones were always found in pairs within the long trichoid sensilla, which are the most abundant multi‐pored sensilla on the male antenna. A systematic survey of all regions of the male antenna with standard extracellular recording techniques was undertaken to find receptor neurones responsive to the remaining five minor components of the female pheromone. Of the 113 long trichoid sensilla sampled, all contained two receptor neurones, one specialized for Z11–14:Ac and a second specialized for Ell –14:Ac. A comparable number of recordings were then obtained from the less abundant classes of multi‐pored sensilla. Two new receptor neurone types were found, responsive to the minor pheromone components (E)‐9‐dodecenyl acetate (E9‐12:Ac) and (Z)‐9‐dodecenyl acetate (Z9‐12:Ac). Scanning electron micrographs indicated that these recordings were obtained from shorter, narrower trichoid sensilla. The majority of these sensilla appeared to contain three neurones capable of spontaneous action potential production. In each sensillum, only one receptor neurone appeared to respond to stimulation with a minor component of the female blend. The remaining two neurones did not respond to the chemical stimuli evaluated.

“…PERCEPTION The distribution of sense organs on male antennae has been the subject of various studies (21,147). All Yponomeuta species examined possess the same types of sensilla, and the number and distribution of these do not differ significantly among the species with the exception of the sensilla trichodea.…”
