“…The movement of the spittlebugs between forest and crops is not very clear [ 65 ] and needs more observations, particularly for N. campestris which was encountered in many environments: forests, dry grassland and olive groves. This fact is different from Italy [ 66 ] and seems closer to the situation in Spain [ 58 ] and Morocco [ 67 ].…”

The present study is an update on the situation of potential vectors of Xylella fastidiosa in Tunisia. Investigations in nine Tunisian regions (Nabeul, Bizerte, Béja, Jendouba, Zaghouan, Kairouan, Ben Arous, Tunis and Manouba) from 2018 to 2021 allowed for the observation of 3758 Aphrophoridae among a total of 9702 Auchenorrhyncha individuals collected by sweep net. Four Aphrophoridae species were identified with Philaenus tesselatus as most abundant (62%), followed by Neophilaenus campestris (28%), Neophilaenus lineatus (5%) and Philaenus maghresignus (5%). Aphrophoridae individuals were found to be particularly abundant in both forests of Nabeul and Jendouba, secondarily in olive groves and dry grassland. Furthermore, their distribution on weed hosts was followed in these two regions where nymphs and adults are widely distributed. P. tesselatus appears to be the most abundant species as determined either by conventional sweep netting for adults or by plant sampling on Sonchus, Smyrnium, Cirsium, Rumex, Polygonum and Picris for nymphs. Limited numbers of adults of P. maghresignus were detected by sweep netting, while nymphs of this species were found on Asphodelus microcarpus only. N. campestris was found in high numbers on plants belonging to the Poaceae family in forests, dry grassland and olive groves whereas N. lineatus occurred on herbs under or near olive trees and in dry grasslands.

“…The last survey carried out in Morocco showed that none of the Cicadellid genera (e.g. Cicadella, Evacanthus and Graphocephala genera) has been reported as potential vectors of X.f were found in Morocco (Haddad et al, 2021). However, it is most important to notice the presence of G. versuta during the survey carried out in Algeria between September 2013 and April 2014 (Boulaouad et al, 2022).…”

“…However, in Europe, P. spumarius is the only important insect vector involved in the ongoing X. fastidiosa outbreak in olive groves in Italy (Saponari et al, 2017;Cornara et al, 2019). A recent survey of potential insect vectors in Morocco was carried out by Haddad et al (2021) where only two main X.f potential insect vectors were recorded, P. tesselatus and N. campestris (Hemiptera: Aphrophoridae).…”

In Morocco, the climate conditions are favorable for the establishment and the spread of Xylella fastidiosa (X.f). However, the successful establishment of the bacterium depends on many factors; mainly: bacterial subspecies and sequence type, host plants susceptibility, feeding behavior and transmission efficiency of the insect vectors. Knowledge of the relationship between the bacterium–affected crop agro-ecosystem and potential insect vectors is of crucial importance. In this work, we list the tritrophic interaction X.f-host plants-insect vectors that occur worldwide in order to apply it to the current situation in Morocco and for risk analysis on the bacterium in the country. Two most relevant X.f subspecies of the bacterium (in terms of impact on crops) were considered, namely, subsp. fastidiosa and subsp. pauca. Based on the international literature and public databases, the majority of the X.f-insect vectors are comprised in two families: Cicadellidae and Aphrophoridae. Among all cicadellid species recorded, a high number had the capacity to transmit X.f to hosts in America while this ability is null for other regions (except Graphocephala versuta Say (Hemiptera: Cicadellidae) recorded in Algeria). In Morocco, none of the cicadellid genera reported worldwide as vectors of X.f, have been so far reported, whereas many species of spittlebugs and leafhoppers are present. Philaenus tesselatus Melichar (Hemiptera: Aphrophoridae) is highly abundant in Morocco and could play a role as potential vector in case the bacterium is introduced in the country. With regard to the X.f hosts, citrus, olive, almond and grapevine, forest agroecosystems and oleander are considered the main susceptible species present in Morocco.

“…The presence of this protective frothy excreta has been traditionally identified as a protection against predation, parasitism, and may create a microclimate that reduces the risks of overheating and desiccation (Chen et al, 2017; Thompson, 1997; Tonelli et al, 2018). They are reported as capable of transmitting the xylem‐limited bacterium Xylella fastidiosa Wells et al, 1987 (Haddad et al, 2021; Peck & Thompson, 2008) and mycoplasmas that cause the stunt disease of Rubus Linneaus, 1753 (Peck & Thompson, 2008), as no viruses replicate in or are transported by plant xylem tissue (Nault & Ammar, 1989). Hanna (1966) and Hamilton (1982) as cited by Cryan and Svenson (2010) also reported that cercopids might be vectors for the fungus Sphaeropsis sapinea (≡ Diplodia pinea ) (Fr.)…”

Molecular phylogeny of Cercopidae (Hemiptera, Cercopoidea)

With 175 described genera and 1556 described species, Family Cercopidae is currently divided into two subfamilies: the paraphyletic Cercopinae and the monophyletic Ischnorhininae. This study, with emphasis on the family Cercopidae, is in line with the extensive work of Cryan and Svenson which is the first phylogenetic study testing the monophyly of this family and higher‐level relationships within Cercopoidea. This study includes more representative taxa from Old World regions. The results of the phylogenetic analysis based on DNA nucleotide sequence data (18S rDNA, 28S rDNA, histone 3, and cytochrome oxidase I) show that Cercopidae is not monophyletic. Three major lineages are recovered: (1) the lineage Microsargane Fowler, 1897 + Hemitriecphora Lallemand, 1949 which is the sister group to Aphrophoridae + Epipygidae, (2) most of the Old World Cercopidae appear as a monophyletic lineage that can be subdivided into two clades, and (3) the monophyletic New World Ischnorhininae, which is separated from the rest of Cercopidae and basal to the two other lineages. It is proposed that Microsargane and Hemitriecphora should be removed from Cercopidae and placed within Aphrophoridae, and only the monophyletic Old World lineage should be kept as Cercopidae sensu stricto. The two subfamilies Cercopinae and Cosmoscartinae, corresponding respectively to the monophyletic lineage groups 2 and 3, should be kept with minimal changes on the tribal level, and the subfamily Ischnorhininae should be raised to family level Ischnorhinidae stat. nov.
