Pseudococcus comstocki (kuwana) su fruttiferi e ornamentali nell’Italia nord-orientale e in altri paesi europei.
No full textP. comstocki (Kuwana) is a polyphagous mealybug native to Eastern Asia and incidentally introduced in many countries. It
was first recorded in Western Europe (Italy and France) in 2004 on ornamental mulberry trees and later detected in other
European countries. It is presently a pest in peach and apple orchards both in Italy and France. Damages consist mostly in fruit quality deterioration. Information on its distribution, host plants, phenology, ethology, damages and natural enemies in northeastern Italy are reported. In North eastern Italy the species develops three annual generations and overwinters mostly in the egg stage. The parasitoid Clausenia purpurea (Ishi) (Encyrtidae) is an active natural enemy of the mealybug presently distributed in the Veneto region. A comparison with the natural enemies of P. comstocki recorded in France and in Japan, the native area of the mealybug, is reported
Strategie di controllo dei vettori associati ai giallumi della vite.
Full text linkFlavescence dorée and Bois noir are grapevine yellows diseases of great economic importance in European viticulture. They
are associated with “Ca. Phytoplasma vitis” and “Ca. Phytoplasma solani” transmitted by the Cicadellidae Scaphoideus titanus
Ball and by the Cixiidae Hyalesthes obsoletus Signoret, respectively. The control strategies of these diseases are based on rouging
of infected plants, source of phytoplasmas, and on vectors control before they are able to inoculate the pathogens in healthy
plants. Since plant sources of phytoplasmas external to vineyards are implicated in the epidemiology of these diseases, control
strategies must be implemented at territorial level and involve all the growers. From 2014, according to CE Directive 128/2009
on “Sustainable use of pesticides”, all growers must adopt alternative methods to chemical control in order to reduce the use
of pesticides. In this contribution we aim to review current monitoring and control techniques as well as the new perspectives
in the control of the grapevine yellows diseases in an Integrated Pest Management context
