“…In New Zealand, for example, Ps. viburni was brought under exceptional control by release of the parasitoid Acerophagus ( Pseudaphycus ) maculipennis Signoret (Charles et al, 2010). In contrast, Anagyrus pseudococci Signoret is the primary parasitoid of Pl.…”

Grapevine leafroll disease (GLD) is caused by a complex of vector-borne virus species in the family Closteroviridae. GLD is present in all grape-growing regions of the world, primarily affecting wine grape varieties. The disease has emerged in the last two decades as one of the major factors affecting grape fruit quality, leading to research efforts aimed at reducing its economic impact. Most research has focused on the pathogens themselves, such as improved detection protocols, with limited work directed toward disease ecology and the development of management practices. Here we discuss the ecology and management of GLD, focusing primarily on Grapevine leafroll-associated virus 3, the most important virus species within the complex. We contextualize research done on this system within an ecological framework that forms the backbone of the discussion regarding current and potential GLD management strategies. To reach this goal, we introduce various aspects of GLD biology and ecology, followed by disease management case studies from four different countries and continents (South Africa, New Zealand, California-USA, and France). We review ongoing regional efforts that serve as models for improved strategies to control this economically important and worldwide disease, highlighting scientific gaps that must be filled for the development of knowledge-based sustainable GLD management practices.

“…Several mealybug species have been reported to occur in vineyards worldwide. These include the vine mealybug Planococcus ficus (Signoret), grape mealybug Pseudococcus maritimus (Ehrhorn), obscure mealybug Pseudococcus viburni (Signoret), long‐tailed mealybug Pseudococcus longispinus (Targioni‐Tozzetti), citrophilus mealybug Pseudococcus calceolariae (Maskell), citrus mealybug Planococcus citri (Risso) and pink pineapple mealybug Dysmicoccus brevipes (Cockerell) (Hemiptera: Pseudococcidae) (Walton & Pringle, ; Charles et al ., ; Daane et al ., ; Morandi Filho et al ., ). Planococcus ficus is a key pest in most grape‐growing areas (the Mediterranean basin, California, Mexico, Argentina, South Africa and the Middle East) (Dalla Montà et al ., ; Walton et al ., ; Daane et al ., ; Mansour et al ., ), whereas P. citri is reported as a grape pest in few countries (Brazil, Chile, India and Spain) (Morandi Filho et al ., , ; Cid et al ., ; Daane et al ., ; Correa et al ., ; Gallardo et al ., ).…”

1 Mealybugs are major pests in grape-growing areas worldwide, causing direct and indirect crop damage. The vine mealybug Planococcus ficus (Signoret) is a key pest in most of grape-producing countries, whereas the citrus mealybug Planococcus citri (Risso) is reported as being destructive in Brazilian and Spanish vineyards. 2 We examined the adaptation of the citrus mealybug to grapevine by investigating its development, reproduction and life-history parameters under Mediterranean field conditions in comparison with those of P. ficus. 3 Both mealybug species developed and reproduced successfully on grapevine. However, P. ficus showed a shorter development time, larger female body size, and higher fecundity, fertility and survival than P. citri. 4 The life-history parameters further highlighted the different growth potential of vine and citrus mealybug populations because P. ficus exhibited a net reproductive rate and an intrinsic rate of increase two-to four-fold higher than that of P. citri. Furthermore, the vine mealybug population doubled its number in approximately half time with respect to the citrus mealybug. 5 Overall, the results of the present study show a better development and reproductive performance and a higher population growth potential of P. ficus compared with P. citri, indicating a higher capacity of the vine mealybug to develop on grapevine in Mediterranean vineyards.

“…Mealybugs associated with grapes showed a lower diversity in several other grape-producing countries such as Argentina, Chile, Italy, New Zealand, Portugal, South Africa and Tunisia, which show an average of three species present in the culture (Borbón et al, 2004;Walton and Pringle, 2004;Mahfoudhi and Dhouibi, 2009;Walton et al, 2009;Bertin et al, 2010;Charles et al, 2010;Correa et al, 2012;Mansour et al, 2012;Maia, 2013). The high species diversity in vineyards difficult the deployment of efficient control programs due to their different life cycles and respond differently to chemical and biological management strategies.…”

a b s t r a c tMealybugs (Hemiptera: Pseudococcidae) are important pests of the grapevine Vitis spp. and are responsible for direct and indirect damage to production. The main mealybug species present in wine grapevine (Vitis vinifera L.) in Southern Brazil were identified and their incidence evaluated. Bunch-samples (n = 50) from 131 vineyards located in the Serra Gaúcha Region (RS) of Brazil were analyzed at harvest, and the occurrence of mealybugs in the roots was evaluated at the time of eradication of plants for replanting. Mealybugs were reared in laboratory until adulthood for species determination. The species Dysmicoccus brevipes (Cockerell, 1983), Dysmicoccus sp., Planococcus citri (Risso, 1813), Pl. minor (Maskell, 1897), Pseudococcus viburni (Signoret, 1875) and Pseudococcus sp. were identified in bunches. Dysmicoccus sp., D. umbambae Granara de Willink, 2009, Pl. citri and Pseudococcus sp. were found in the roots. Pl. citri (31.4%) and Dysmicoccus sp. (22.7%) were the most common species found in wine grape bunches in the Serra Gaúcha Region.
