The taxonomic position of Flavobacterium okeanokoites IFO 12536T (T = type strain) was determined by 16S rRNA gene sequencing and chemotaxonomic methods. Phylogenetic evidence derived from a 16S rRNA sequence analysis indicated that F. okeanokoites, which forms rod-shaped cells, belongs to the genus Planococcus, which forms spherical cells. A phylogenetically close relationship was supported by...

Abstract The mealybug Planococcus ficus is one of the main vectors Grapevine leafroll associated virus-3 (GLRaV-3), which was commonly detected in cv “Albariño” planting material before certified stock available. Mealybug infestations were rare vineyards southern Galicia (NW Spain) during 1990s (2.2% surveyed) and are still inland zones. However, have spread since 2000, with 15% surveyed infest...

Vine mealybug Planococcus ficus Signoret (Hemiptera: Pseudococcidae) is an important phloem-feeding pest species in many grapevine producing areas worldwide. The economic damage of P. thought to be mainly caused by sooty mould on infested grape clusters and transmission plant viruses. Direct feeding plants (Vitis vinifera, L.) has only been vaguely described or otherwise completely discarded. p...

Nitrogen is a key macronutrient for the quantitative and qualitative yield of grapes; in addition, it influences development reproduction grape pests. The multiple effects different nitrogen rates were investigated on red berry cultivar ‘Carignano’ pest Planococcus ficus two-year field trial. Different amounts ammonium nitrate compared: 0, 80 160 Units ha−1 mineral nitrogen. amount fertilizatio...
