“…No Brasil, P. citri é mencionada como uma das espécies de Pseudococcidae associadas à cultura da videira (Foldi & Soria, 1989) junto com P. maritimus, P. longispinus, P. viburni e P. fi cus (Kuniyuki et al, 2005;Foldi & Kozár, 2006). A espécie P. citri é responsável pela transmissão dos vírus do enrolamento-da-folha da videira (GLRaV-3), das caneluras-do-tronco da videira (GVA) e do intumescimento-dos-ramos (GVB), importantes viroses que têm prejudicado de forma signifi cativa a viticultura mundial (Cabaleiro & Segura, 1997;Cid et al, 2007).…”

Resumo -O objetivo deste trabalho foi estudar a biologia e a tabela de vida de fertilidade de Planococcus citri, em folhas de videira das cultivares Cabernet Sauvignon, Itália e Isabel, em bagas de uva 'Itália' e em raízes da 'Isabel' e dos porta-enxertos 101-14 e IAC-572. Os seguintes parâmetros foram avaliados: duração e viabilidade dos estágios de ovo e ninfa; e fecundidade e longevidade dos adultos. Em raízes do porta-enxerto IAC-572, a cochonilha não completou o ciclo biológico. Em bagas de uva 'Itália', o inseto completou a fase de ninfa, porém os adultos foram inférteis. Em folhas das diferentes cultivares, a duração média do período de ovo a adulto dos machos foi de 24,63 dias, com viabilidade de 32%, enquanto as fêmeas duraram 32 dias com viabilidade de 56%. Em raízes, a duração do ciclo biológico de fêmeas e machos foi de 32,45 e 29,50 dias, respectivamente. Em folhas, a fecundidade foi de 67,27, 66,09 e 53,33 ovos por fêmea, nas cultivares Cabernet Sauvignon, Isabel e Itália, respectivamente. Nas raízes foram obtidos 30,4 e 70,0 ovos por fêmea, no porta-enxerto 101-14 e na cultivar Isabel, respectivamente.Termos para indexação: Vitis, Pseudococcidae, ciclo biológico, cochonilha-farinhenta, taxa de reprodução. Biology and fertility life table of Planococcus citri in different vegetative structures of grape cultivarsAbstract -The objective of this work was to study the biology and fertility life table of Planococcus citri in leaves of the grape cultivars Cabernet Sauvignon, Itália and Isabel, in berries of 'Itália', in roots of 'Isabel' and 101-14 and IAC-572 rootstocks. The following parameters were evaluated: duration and viability of the egg and nymph stages; and fertility and longevity of the adults. On berries of 'Itália', the insect completed the nymph phase, however the adults were infertile. On roots of the rootstock IAC-572, citrus mealybug was unable to develop. On leaves of the grape cultivars, the period of egg to adult males was 24.63 days, with viability of 32%, while females lasted 32 days with viability of 56%. On roots, the duration of the cycle of females and males was 32.45 and 29.50 days, respectively. For females fed on leaves, the fertility rate was 67.27, 66.09 and 53.33 eggs per female, in 'Cabernet Sauvignon', 'Isabel' and 'Itália', respectively; while on roots, fertility was 30.4 e 70.0 eggs per female, in the rootstock 101-14 and in the cultivar Isabel, respectively.

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.
