“…Both dendrites are present in the peg and fill its lumen almost completely without the presence of lymph around them, a typical feature of thermoreceptors. These sensilla show the same characteristics in aphids (Bromley et al, 1979) and in other insect orders (Boo and McIver, 1975;Romani and Stacconi, 2009;Stacconi and Romani, 2012). Behavioral and electrophysiological evidence also support a function of thermoreceptors for sensilla coeloconica on the antennal tips of mosquitoes (Sutcliffe, 1994).…”

The antennal sensilla of alate Myzus persicae were mapped using transmission electron microscopy and the ultrastructure of sensilla trichoidea, coeloconica, and placoidea are described. Trichoid sensilla, located on the tip of the antennae, are innervated by 2-4 neurons, with some outer dendrites reaching the distal end of the hair. Coeloconic sensilla in primary rhinaria are of two morphological types, both equipped with two dendrites. Dendrites of Type II coeloconic sensilla are enveloped in the dendrite sheath, containing the sensillum lymph. In sensilla coeloconica of Type I, instead, dendrites are enclosed by an electron opaque solid cuticle, with no space left for the sensillum lymph. The ultrastructure of big placoid sensillum reveals the presence of three groups of neurons, with 2-3 dendrites in each neuron group, while both small placoid sensilla are equipped with a single group of neurons, consisting of three dendrites. Both large and small placoid sensilla bear multiple pores on the outer cuticle. The function of these sensilla is also discussed.

“…The main scenario for the appearance of Flavescence dorée in vineyards implies a role for other vectors in introducing the phytoplasma to cultivated grapevines from wild plants. The leafhopper Oncopsis alni (Maixner et al 2000;Arnaud et al 2007) and the planthopper Dictyophara (Stacconi and Romani 2012). Despite such a reduction in olfactory sensory equipment, S. titanus can still detect Vitis leaves and shoot odours (Mazzoni et al 2009a), but extended electrophysiological and behavioral studies have not been conducted.…”

International audienceFlavescence dorée is a serious disease for European vine growers. Indeed, Flavescence dorée causes yield losses and lower grape quality. As a consequence, Flavescence dorée is costly and needs advanced control strategies. For instance, in 2005, 34 million Euro was given to Italian vine growers to compensate losses due to the disease. The infection by Flavescence dorée results from the association of a phytoplasma and the leafhopper vector, Scaphoideus titanus. Despite mandatory controls using insecticides, Flavescence dorée is still spreading in Europe. Here, we review the biology and ecology of S. titanus to suggest improved management techniques. The main findings are as follows. (1) The long-distance spread of S. titanus is mainly due to human activities, and all European vineyards are susceptible to be colonized. (2) S. titanus is an efficient vector because it can reach a high population level and it is specific to Vitis spp. (3) Current control and prophylaxis are insufficiently effective. (4) Variation in vector populations and vector capacities lead to differential risks of plant infection. Factors driving such population variations could be modeled to improve S. titanus control. (5) Feeding behavior is a key factor in the phytoplasma–vector relationship. (6) The infection risk is mainly limited by vector control. To decrease pesticide use, a cross survey of the vector population and of the infected stocks triggers mandatory treatments. (7) Alternative sustainable methods or strategies are required to reduce insecticide use and increase control efficiency. In the short term, new models could support the establishment of more sustainable pest management operations. In the long term, innovative techniques involving symbionts, mating disruption and a push–pull strategy could improve S. titanus and Flavescence dorée control with less environmental impact

“…The antennal sensilla, in particular, play a significant role in detecting semiochemicals (Ma and Du, ). Although sensilla have been intensively examined in various insects (Faucheux, ; Gao et al, ; Hu et al, ; Stacconi and Romani, ; Sun et al, ), including ultrastructural observations of antennal sensilla of many coleopterans (Merivee et al, ; Perez‐Gonzalez and Zaballos, ; Ren et al, ; Yu et al, ; Zhang et al, ), research of the antennae and sensilla of X. grayii has not yet been conducted. The objective of this study was to investigate the type, morphology, and distribution of X. grayii sensilla using scanning electron microscopy (SEM) and to explore their potential functions by comparison with other types of sensilla already known in other coleopteran insects.…”

The longicorn beetle Xylotrechus grayii (White, 1855) has been spreading rapidly in China, causing mass mortality of honeysuckle which is economically and medicinally important. In order to elucidate the mechanisms of mate and host location and to advance efficient control methods, antennal sensilla features were investigated in both sexes of X. grayii using scanning electron microscopy (SEM). The filiform antennae of both sexes consist of scape, pedicel, and nine flagellomeres (f1-9). Five types of sensilla were observed: sensilla chaetica (5 subtypes, SC1-5), sensilla basiconica (4 subtypes, SB1-4), B€ ohm bristles (Bm), grooved peg sensilla (Gp), and sensilla campaniformia (Ca). SC were most common on the antennae, followed by SB and Bm. No significant sexual differences in the type, amounts, and distribution of antennal sensilla were found except for the distribution of SB clusters and Ca. SB clusters and Ca occurred on f1-8 of male antennae but were absent on those segments in females, suggesting a potential function as receptors for female sex pheromones. The putative functions of other sensilla are discussed based on their characteristics in related species. This study provides an important foundation for further research on sensory mechanisms and control measures of X. grayii. Microsc. Res.
