“…Regarding the palpus, observations that were made with SEM exhibited two types of sensilla, sensilla basiconica and sensilla chaetica. The porous hair shafts of the small sensilla basiconica seen in this study were similar to those of sensilla basiconica in the palpus of the pomace fly, Drosophila (Diptera: Drosophilidae;de Bruyne et al 1999), and flesh fly, Neobellieria bullata (Diptera: Sarcophagidae; Wasserman and Itagaki 2003), as well as the sensilla basiconica type II described in the antenna of the eucalyptus woodborer, Phoracantha semipunctata (Coleoptera: Cerambycidae) by Lopes et al (2002). Likewise, this type of sensillum was also documented in the palpus of the sheep head fly, Hydrotaea irritans (Diptera: Muscidae; Been et al 1988).…”

The fine structure of Chrysomya nigripes Aubertin, a blow fly species of medical importance, is presented using scanning electron microscopy (SEM) to contribute information on the morphology of the adult of this fly species. The surface of the dome-shaped ommatidia exhibits a microscopic granulose appearance. The palpus is equipped with small sensilla basiconica and sensilla chaetica, which provide sensory reception for detecting environmental information. At the apex of the mouthparts, the labellum is endowed with large numbers of sensilla trichodea and basiconic-like sensilla of variable length. The anterior (mesothoracic) spiracle is elliptical in shape and covered with extensively ramified setae except for a small dorsal aperture. The posterior (metathoracic) spiracle is shaped like a rounded isosceles triangle and covered by two valves of unequal size. The larger valve covers the upper approximately 2/3 of the spiracular opening, whereas the smaller valve covers the lower approximately 1/3 of the opening. Extensively ramified setae line and cover the valves over the entire spiracle. SEM analyses of the haltere knob and the prosternal organs, located adjacent to the cervical sclerites, revealed a striking resemblance of the morphological features of their sensilla. Each sensillum emanates from a cuticular ring, is approximately 12-15 mum in length, has a smooth surface, and terminates in a sharp tip. Various types of sensilla were associated with the ovipositor including sensilla trichodea, sensilla basiconica, sensilla placodea and probably sensilla styloconica. The possible function of sensilla distributed in particular regions of the fly integument is discussed.

“…In T. lewisi, the TEM analysis showed that sensilla basiconica have a thin cuticle wall, a high density of dendritic branches inside the lymph lumen and a series of pores and pore kettles on the cuticular wall. This kind of structure probably serves an olfactory function as indicated by previous works (Zacharuk 1980(Zacharuk , 1985Been et al 1988;Steinbrecht 1997;Lopes et al 2002;Chen & Fadamiro 2008).…”

This work provides the first morphological analysis (both at gross and fine level) of the antennal structures in the genus Elater (Coleoptera, Elateridae). The typology, number and distribution patterns of the antennal sensilla in the rare saproxylic Elater ferrugineus (both male and female) were studied using scanning electron microscopy (SEM). The serrate antennae of E. ferrugineus consisted of a scape, a pedicel, and nine flattened flagellomeres. Overall, 10 types of sensilla were identified according to their morphological features: one type of sensilla chaetica (Ch), one type of Böhm sensilla (Bo), three types of sensilla trichodea (Tr.1-3), two types of sensilla basiconica (Ba.1-2), one type of sensilla styloconica (St), one type of grooved peg sensilla (Gp) and one type of sensilla campaniformia (Ca). A marked sexual dimorphism was found at both gross and fine scale. The male antenna was bigger (8.6 mm) than the female one (7.0 mm) and carried one type of sensilla trichodea (Tr.2) absent in female antennae possibly responsible for reception of the female-emitted sex pheromone. The female antenna carried a higher number of sensilla (~9800) than the male one did (~7,000), with more abundant sensilla chaetica (Ch) and basiconica (Ba.1 and Ba.2).

“…Sensilla trichodea have been found to play a major role in sensing mechanical stimuli and in recognizing chemical stimuli in insects (Roth & Willis 1951;Amornsak et al 1998;Roux et al 2005;Abdel-latief 2007;Onagbola & Fadamiro 2008), whereas sensilla basiconica are considered olfactory receptors in phytophagous insects and are sensitive to host plant chemicals. The morphology of these sensilla suggests that they are sensitive to many kinds of chemical stimuli (Kaissling 1986;Isidoro et al 1998;Lopes et al 2002;Onagbola & Fadamiro 2008). …”

“…Sensilla basiconica were found only on the last 3 segments of the antennae and were absent on the first 8 segments in both sexes. The majority of the sensilla basiconica subtypes found in T. castaneum have been identified previously on the antennae of many other insect species, such as Pterostichus melanarius (Illiger) and Pterostichus niger (Schaller) (Coleoptera: Carabidae) (Symondson & Williams 1997), Manduca sexta L. (Lepidoptera: Sphingidae) (Shields & Hildebrand 1999), Phoracantha semipunctata (F.) (Coleoptera: Cerambycidae) (Lopes et al 2002), Lophocorona pediasia Common (Lepidoptera: Lophocoronidae) (Faucheux 2006), and Cochliomyia hominivorax Coquerel (Diptera: Calliphoridae) (Fernandes et al 2004). No previous study described twin sensilla basiconica similar to those found on antennae of T. castaneum (Fig.…”
