Newly available Pherobank product, pheromone lure for Pseudococcus viburni
Pseudococcus viburni
English name: Obscure mealybug
Pseudococcus viburni is a cosmopolitan species which is thought to originate from South America. Due to some taxonomic confusion, both its origin and geographical distribution remain difficult to establish with certainty. It is currently considered that P. viburni belongs to the 'Pseudococcus maritimus complex', and that Dactylopius affinis, P. affinis, P. capensis, P. indicus, P. latipes, P. longispinus var. latipes, P. malacearum, P. nicotianae, P. obscurus are all synonyms for the same species.
The insect is polyphagous and can be found on most parts of its hosts including the main roots, fruit, leaves, stems, and under bark crevices. It attacks economically important crops such as: apple, pear, citrus, grapevine, pomegranate, stone fruit, strawberry, tomato, walnut but also on ornamental plants. In vineyards, P. viburni has been shown to transmit viruses. It is generally considered as a minor pest but in some cases, control measures are necessary.
