“…maritimus produces two synchronous generations per year that do not overlap, and our inoculation study coincided with the emergence of the second generation in July (Daane et al 2012). Differing climatic conditions during the first generation, which usually emerges in March, could potentially lead to different transmission efficiency and different timing of disease development.…”

“…Cabernet franc vines in Napa Valley, CA USA. We used first instars of the vector Pseudococcus maritimus (Ehrhorn), a mealybug species that is a common vineyard pest and native to North America (Daane et al 2012). We performed a concurrent laboratory study, with identical experimental design, to compare pathogen transmission efficiency under controlled laboratory and field conditions.…”

TitleAbstract Grapevine leafroll-associated virus 3 (GLRaV-3) is associated with the economically damaging grapevine leafroll disease, and is transmitted in a semi-persistent manner by several mealybug species. We performed the first controlled field study of vectormediated inoculations with GLRaV-3 in a commercial vineyard with previously asymptomatic vines, and monitored the vines during four growing seasons. We then compared the outcome of vector-mediated inoculations in the field study to an analogous laboratory study. In the vineyard, about half of all inoculated plants became infected with GLRaV-3, fewer than in the controlled laboratory inoculations. Mealybugs had lower settling and feeding success in the field than in the laboratory inoculations. Our study suggests that laboratory studies may overestimate transmission efficiency. All successfully inoculated vineyard plants first became symptomatic one growing season after inoculations, and berry quality declined within one year after inoculations. Vineyard plants were effective virus sources one year after inoculations. Our findings generally indicate that newly symptomatic vines in commercial vineyards probably became infected during the previous growing season, and a decline in berry quality can be expected during the same year in which symptoms appear.

“…The vine mealybug Planococcus ficus (Signoret) Mealybugs may be considered the most universally important vineyard pests (Daane et al 2012). Among mealybug species, the VM P. ficus constitutes the major and most damaging species in Tunisian vineyards (Mansour et al 2011a;Mansour 2012), which is also the case for several other grape-growing areas around the world (Trjapitzin & Trjapitzin 1999;Dalla Montà et al 2001;Walton et al 2009;Fal- Daane et al 2012).…”

Mansour R., Grissa-Lebdi K., Suma P., Mazzeo G., Russo A. (2017): Key scale insects (Hemiptera: Coccoidea) of high economic importance in a Mediterranean area: host plants, bio-ecological characteristics, natural enemies and pest management strategies -a review. Plant Protect. Sci., 53: 1-14.Key scale insects that have long been considered as having high economic importance in Tunisia and for which several research studies and pest management programs have been undertaken include the mealybug species Planococcus ficus (Signoret) and Planococcus citri Risso, the soft scale saissetia oleae (Olivier) and the armoured scale Parlatoria ziziphi (Lucas). The host plants, bio-ecological aspects, auxiliary fauna of each of the aforementioned species as well as the related economic losses and pest management strategies adopted are explored and discussed. Among these species, P. ficus is considered herein as the most economically important in Tunisia. Still, the present contribution constitutes the first review article on key scale insects infesting plants in the South Mediterranean Maghreb area.
