“…The host plant of C. picta is known and it has been suggested [17], but not proven, that adult psyllids also feed on other plant taxa. C. picta can survive for up to four days without food (Figure A2), but the insect lives for only four or five months a year on its host [19,20]. This leads to the conclusion that C. picta must feed from plants other than Malus.…”

“…In northern Italy, C. picta's reproduction takes place from mid-March until the beginning of August [19,20]. During this period, the overwintered adults-the so-called remigrants-of C. picta can be detected in apple orchards until the beginning of June, while the young adults of the new generation-the so-called emigrants-occur from the end of June until the beginning of August [19,20]. During the rest of the year, adults of C. picta dwell on shelter plants, mostly conifers at higher elevations [21].…”

Apple proliferation is an economically important disease and a threat for commercial apple cultivation. The causative pathogen, the bacterium ‘Candidatus Phytoplasma mali’, is mainly transmitted by Cacopsylla picta, a phloem-feeding insect that develops on the apple tree (Malus spp.). To investigate the feeding behavior of adults of the phytoplasma vector Cacopsylla picta in more detail, we used deep sequencing technology to identify plant-specific DNA ingested by the insect. Adult psyllids were collected in different apple orchards in the Trentino-South Tyrol region of northern Italy. DNA from the whole body of the insect was extracted and analyzed for the presence of plant DNA by performing PCR with two plant-specific primers that target the chloroplast regions trnH-psbA and rbcLa. DNA from 23 plant genera (trnH) and four plant families (rbcLa) of woody and herbaceous plant taxa was detected. Up to six and three plant genera and families, respectively, could be determined in single specimens. The results of this study contribute to a better understanding of the feeding behavior of adult Cacopsylla picta.

The mitochondrial genomes of two vector psyllids of the ‘Candidatus Phytoplasma mali’, Cacopsylla picta and C. melanoneura, were sequenced using high-throughput sequencing on the Illumina platform. The main objective of the study was to describe their mitogenome and characterize their genetic variability and the potential changes in the context of the observed global warming. The four complete sequences for C. picta, 14,801 bp and 14,802 bp in length, two complete and one partial sequence for C. melanoneura, ranging from 14,879 bp to 14,881 bp in length, were obtained for the first time for these European apple psyllids. The detected intraspecies mtDNA identity was highly similar (99.85–99.98%), the identity’s similarity with other Cacopsylla species varied between 79.79 and 86.64%. The mitogenomes showed a typical mitochondrial DNA structure with 13 protein-coding genes, 2 rRNA genes and 22 tRNA genes; the presence of CGGA motif in the ND1-trnS2 junction was detected in both species. Phylogenetic analysis placed both species in close relationship with C. burckhardti within the Cacopsylla clade-I O group. The analysis of complete mitogenomes and of partial COI sequences of fifty-two Cacopsylla individuals showed a high homogeneity of genotypes over 15 years and among the different localities in the Czech Republic.

Current climate change has led to an expansion of the ranges of many phytophagous species, an increase in the density of their populations, the number of generations and the intensity of plant damage. The purpose of this work was to assess the distribution and trophic relationships of the invasive buffalo treehopper Stictocephala bisonia Kopp et Yonke, 1977 (Insecta: Hemiptera: Membracidae) in the Samara region, as well as to determine the area of its distribution in the Russian Federation at the end of 2023. For the first time, adults of S. bisonia were recorded in Samara region in July 2009. Between 2011 and 2023, treehoppers were found in four Samara region districts. Totally, 116 leafhopper specimens were caught in 57 surveys. An average of 8.2 treehoppers were caught on herbaceous vegetation, and 6.0 specimens on tree species per 100 sweeps of the net. In the Samara region, in addition to forbs, the treehopper has been recorded on 24 plant species from 12 families. According to GBIF data, S. bisonia is distributed in 28 administrative Russian entities, the northernmost point is in the Nizhny Novgorod region (56.4N, 43.9E; 08/23/2023) and the easternmost point is in Bashkiria (51.9N, 58.2E; 07/29/2021). S. bisonia assumed to be a serious pest of young fruit trees and berry bushes.
