Mating disruption field experiments to control the vine mealybug, Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae), were carried out in 2008 and 2009 in two commercial vineyards in Sardinia (Italy). The effectiveness of mating disruption was evaluated by testing reservoir dispensers loaded with 100 mg (62.5 g/ha) and 150 mg (93.8 g/ha) of the sex pheromone in 2008 and 2009, respectively...

Çalışmada, en önemli unlubit avcılarından biri olan Nephus includens Kirsch (Coleoptera: Coccinellidae)’in, bağların zararlılarından Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae)’un farklı dönemleri üzerindeki tüketim kapasitesi ve dönem tercihi araştırılmıştır. Denemeler 25 ± 1 ºC sıcaklık, %60 10 nem 16:8 (aydınlık/karanlık) koşullarındaki iklim kabinlerinde yürütülmüştür. N. inclu...

Increasing international trade and tourism have led to an increase in the introduction of exotic pests that pose a considerable economic threat to the agro-ecosystems of importing countries. Scale insects (Sternorryncha: Coccoidea) may be contaminants of export consignments from the South African deciduous fruit industry to the European Union, Israel, United Kingdom and the United States, for e...

Controlled atmosphere treatments with ultralow oxygen (ULO treatments) were developed successfully for control of vine mealybug, Planococcusflcus Signoret (Hemiptera: Pseudococcidae), on dormant grape (Vitis spp.) benchgrafts. At 30 ppm oxygen, 3-d ULO treatment at 25 degrees C and 4-d ULO treatment at 150C achieved complete control of all life stages of P. ficus. At a much lower oxygen level (...

Presented here is the whole-genome sequence of a previously uncharacterized species of the genus Planococcus. A 16S sequence analysis shows that this bacterium exhibits 98% sequence identity to the closest relative of Planococcus kocurii. Whereas most species of Planococcus produce yellow to orange pigments, the species described here produces black pigmentation.

The taxonomic position of a bacterium isolated from a cold desert of the Himalayas, India, was analysed by using a polyphasic approach. The isolated strain, designated K22-03T, had phenotypic characteristics that matched those of the genus Planococcus and it represents a novel species. The almost-complete 16S rRNA gene sequence (1464 bases) of the novel strain was compared with those of previou...
