Cacopsylla melanoneura (Foerster): aestivation and overwintering habitats in Northwest Italy
Cacopsylla melanoneura (Foerster) is considered one of the most important vectors of ‘Candidatus Phytoplasma mali’, the phytoplasma associated with apple proliferation disease. In the last years several studies concerning the biology, the infectivity and the transmission activity of this psyllid highlighted the crucial role of the overwintered adults in the epidemiology of the disease. However ...
متن کامل‘Candidatus Phytoplasma mali’: the current situation of insect vectors in northwestern Italy
The two acknowledged vectors of ‘Candidatus Phytoplasma mali’ in north-western Italy, the psyllid Cacopsylla melanoneura and the leafhopper Fieberiella florii, have been compared to highlight their role in the apple proliferation epidemiology in relation to their infectivity, transmission efficiency and permanence in apple orchards and in wild vegetation, predominantly hawthorn formations. The ...
متن کاملEcological and Genetic Differences between Cacopsylla melanoneura (Hemiptera, Psyllidae) Populations Reveal Species Host Plant Preference
The psyllid Cacopsylla melanoneura is considered one of the vectors of 'Candidatus Phytoplasma mali', the causal agent of apple proliferation disease. In Northern Italy, overwintered C. melanoneura adults reach apple and hawthorn around the end of January. Nymph development takes place between March and the end of April. The new generation adults migrate onto conifers around mid-June and come b...
متن کاملCandidate insect vectors of apple proliferation in Northwest Spain
The apple proliferation (AP) disease is spread mostly by two psyllids. Each species plays a predominant role as AP vector that changes regionally. Thus, there is an urgent need to identify the AP vectors in each region where the disease is present. This research aimed at identifying the psyllid community in apple orchards from Asturias (NW Spain) and studying their possible role in AP transmiss...
متن کاملDNA-based discrimination and frequency of phytoplasma infection in the two hawthorn-feeding species, Cacopsylla melanoneura and Cacopsylla affinis, in northwestern Italy.
A molecular tool, focused on the mitochondrial Control Region (CR), was developed to discriminate the two hawthorn-feeding psyllid species, Cacopsylla melanoneura (Förster) and C. affinis (Löw), and to estimate their frequencies in mixed populations. The test was carried out in paired and single-tube amplifications and validated analysing 52 male specimens previously determined by morphological...
