“…However, those authors refer to two types of trichoid (type I and II) and only one clavate sensilla, while we found one trichoid and two types of clavate sensilla. Dickens et al (1988), in studies of C. capitata, A. ludens, Dacus cucurbitae (Coquillett), and Dacus dorsalis (Hendel) also registered the same types found in this study, but used different names: non-porous sensilla (NPS) for chaetica, multiporous grooved sensilla (MPGS) for styloconic, and multipore sensilla (MPS) for trichoid and basiconic.…”

“…The antennae of A. fraterculus have three segments: scape, pedicel, and lagellum (Fig1a), similar to other species of Tephritidae (Giannakakis & Fletcher 1985, Dickens et al 1988, Hull & Cribb 1997, Arzuf i et al 2008. The arista was inserted on the dorso-proximal end of the lagellum, and a sensorial pore was present on the lateral surface as reported for several other species by Dickens et al (1988).…”

“…The arista was inserted on the dorso-proximal end of the lagellum, and a sensorial pore was present on the lateral surface as reported for several other species by Dickens et al (1988). The length of the antennae and of each segment and arista did not differ between females and males (Table 1).…”

“…The antennal sensilla may be associated with chemical perception and behavioral responses (Zacharuk 1980) as observed in Tephritidae species such as Ceratitis capitata (Wied.) (Levinson et al 1987), Bactrocera tryoni (Froggatt) (Giannakakis & Fletcher 1985), and Anastrepha ludens (Loew) (Dickens et al 1988).…”

“…In some species of Bactrocera, TS, CS and basiconic sensilla have been identified on tarsi (Zhang et al 2012); moreover, in Helicoverpa assulta, trichoid chemosensilla on the fifth tarsomere were reported (Zhang et al 2011). In Ceratitis and generally in Tephritidae, similar sensilla were observed in antennal segments (Mayo et al 1987;Dickens et al 1988;Bigiani et al 1989;Hu et al 2010;Bisotto-De-Oliveira et al 2011). CS were considered mechanoreceptors, and basiconic sensilla have been related to olfaction, while TS could have multiple (mechano, olfactory or gustatory) functions (Zhang et al 2012).…”

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae), is a polyphagous pest in horticulture, mainly targeting pomaceous and citrus fruits. To gain better knowledge about its chemosensory system related to taste, essential for behavioural strategies and localisation of host plants, we examined the tarsal external morphology by highresolution scanning electron microscopy, focusing on sensilla. Numerous trichoid and chaetica sensilla, related to taste and mechanoreceptor systems, and other types of sensilla are present in tarsal segments. The responses of specific trichoid chemosensilla were also studied through electrophysiological experiments by stimulation with sodium chloride, fructose and four bitter stimuli. Electrophysiological data allowed us to distinguish three types of different neurons: high ("H"), middle ("M") and small ("S"). Increasing concentrations of sodium chloride enhanced the activity of H cells, while fructose boosted M cells activity. On the contrary, S cells showed no increase in spike activity after stimulation with these substances. Bitter stimuli induced no significant response on these cells. Behavioural assays showed no statistical difference among the responses to sugars, bitter substances and citric acid. Our results on taste stimuli will be useful in increasing knowledge of Ceratitis chemoreception, fundamental in new integrated pest management.

Electroantennograms (EAGs) of unmated laboratory-reared male and femaleCeratitis capitata (Wiedemann) were recorded in response to the attractant trimedlure [tert-butyl 4(and 5)-chloro-trans-2-methylcyclohexane-1-carboxylate] and its fourtrans isomers. For both sexes, the magnitude of the EAG response was relatively low as compared to other previously tested compounds (i.e., plant volatiles). Dosage-response curves generated for all TML isomers revealed that flies responded to increasing dosages over a relatively narrow range (two to three log steps). Responses for both sexes peaked at ca. 10 μg dose for all isomers. Antennal response in males was greatest to the C isomer followed by the B1, A, and B2 isomers, while responses of females were greatest for the A isomer followed by B1, C, and B2. Both sexes exhibited a long recovery period for the response potential to return to baseline at doses above 1 μg for all of the isomers tested, except for B2. The low EAG sensitivity to trimedlure and the apparent EAG selectivity to the C isomer in males are discussed in relation to the known field attractancy of males to the C, A, B1, and B2 isomers.
