“…According to our experience collecting Cicadellinae samples in the wild, they prefer to live in the humid and well-lit forests of the mountains. Some Cicadellinae species are of considerable economic importance because they feed on the sap in the xylem of woody and herbaceous plants and are important vectors of the xylem-limited bacterial pathogen Xylella fastidiosa , which induces diseases of grapevines, citrus, alfalfa, almond, coffee, stone fruits, and landscape ornamentals [ 8 , 9 , 10 , 11 ].…”

The herbivorous leafhopper genus Atkinsoniella Distant, 1908 (Hemiptera: Cicadellidae: Cicadellinae), a large genus of subfamily Cicadellinae, consists of 98 valid species worldwide and 88 species recorded in China. Some species of the genus are very similar in morphological characteristics, so they are difficult to identify accurately. In this study, 12 mitochondrial genomes of Atkinsoniella species with similar morphological characteristics were first obtained through high-throughput sequencing, which featured a typical circular molecule of 15,034–15,988 bp in length. The arrangement and orientation of 37 genes were identical to those of typical Cicadellidae mitogenomes. The phylogenetic relationship within the subfamily Cicadellinae was reconstructed using maximum-likelihood (ML) and Bayesian inference (BI) methods based on three concatenated datasets. The topological structures of the six obtained phylogenetic trees were highly consistent. The results suggested that Atkinsoniella was recovered as a monophyletic group and emerged as a sister group with the monophyletic clade of Bothrogonia, Paracrocampsa (part), and Draeculacephala (part). The branches of the 12 newly sequenced species were clearly separated, with most nodes receiving strong support in all analyses. In addition, the key to the 12 Atkinsoniella species was provided to identify species according to morphological characteristics. This study further promotes research on the classification, genetics, evolution, and phylogeny of the genus Atkinsoniella and subfamily Cicadellinae.

“…In China, 26 genera and 315 species of Cicadellinae have been recorded [2]. Some Cicadellinae insects are of considerable economic importance as they feed on sap in the xylem of woody and herbaceous plants and, via this process, are able to transmit phytopathogenic bacterium and plant viruses to crops, ornamental plants, and weeds [3][4][5][6]. Accurate identification of insects is extremely important for pest control.…”

The complete mitochondrial genomes of Atkinsoniella grahami and Atkinsoniella xanthonota were sequenced. The results showed that the mitogenomes of these two species are 15,621 and 15,895 bp in length, with A+T contents of 78.6% and 78.4%, respectively. Both mitogenomes contain 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and a control region (CR). For all PCGs, a standard start ATN codon (ATT, ATG, or ATA) was found at the initiation site, except for ATP8, for which translation is initiated with a TTG codon. All PCGs terminate with a complete TAA or TAG stop codon, except for COX2, which terminates with an incomplete stop codon T. All tRNAs have the typical cloverleaf secondary structure, except for trnS, which has a reduced dihydrouridine arm. Furthermore, these phylogenetic analyses were reconstructed based on 13 PCGs and two rRNA genes of 73 mitochondrial genome sequences, with both the maximum likelihood (ML) and Bayesian inference (BI) methods. The obtained mitogenome sequences in this study will promote research into the classification, population genetics, and evolution of Cicadellinae insects in the future.

“…xanthophis and S . sagata showed variations in settling and feeding preferences for the three plum genotypes SC7, SC13, and Laetitia (Kleina et al, 2020), which led us to believe that cedrol can act as a natural repellent in these new plum genotypes.…”

Volatile compounds from plum genotypes with different levels of resistance to leaf scald disease

Plum leaf scald (PLS) is the main obstacle to plum expansion in Brazil. This disease is caused by Xylella fastidiosa, which colonizes the foregut of xylem‐sap feeding insects and the xylem of the plants. Breeding programmes identified new plum genotypes that showed no leaf scald symptoms in the field and remained negative for X. fastidiosa for at least 10 years. However, the mechanisms that confer this resistance are not fully elucidated. One hypothesis is the emission of volatile organic compounds by the host. Therefore, we investigated the volatile compound profile from six plum genotypes with different resistance levels to PLS. Thirty‐nine compounds were identified. The major constituents in the plum volatile extract were phytol (46.76%) and limonene (2.48%). Cultivar Laetitia presented the highest total alkane content, Simka showed the highest alcohol content, while Fortune and SC13 exhibited the highest concentration of ketones. Cedrol was not detected in susceptible genotypes but was found in the resistant ones, SC7 and SC15. (E,E)‐α‐farnesene was detected in high concentrations in Fortune but was not found in SC13 and SC15. According to principal components analysis, genotypes were divided into four groups based on the similarity of the volatile profile: 1: Fortune and Laetitia; 2: Simka and SC13; 3: SC7; and 4: SC15. This is the first description of leaf volatile chemical components of Prunus salicina, and the putative factor related to resistance in SC7 and SC15 is discussed. We also propose a terpene pathway of the main volatile compounds found.
