Part of the evidence supporting the separation of this population was the host-plant preferences.

Ants feed on a sugary substance produced by Cinara cupressi and contribute to their diffusion by transferring them from one part of the tree to another, thus creating new areas of infestation. Annali – Accademia Italiana di Scienze Forestali, What Does The Law Say?


History of Introduction and Spread Top of page The following dates of introduction relate to the countries where the aphids have been reported as causing significant damage or as recent introductions. At least one of the populations within C. Examples of natural enemies that may be explored for use as biocontrol agents are Pauesis cupressobii and P.

It damages commercial and ornamental plantings. Additional species of Aphidoidea in Israel. The authors found that damage decreased over the period of the study.

Their multivariate analysis also demonstrated that Cinara sabinae might be partially identifiable using morphology. It was suggested that one cycle of selection might yield a resistant population. They suggested that it probably originated on Cupressus sempervirens in an area between eastern Greece and just south of the Caspian sea Watson cupeessi al.

Observations on the impact of infestation on different tree species in the arboretum indicated that there is a wide range of tolerance between different species Obiri, Annals of Applied Biology, 1: It may be undertaken in hedges or ornamental trees, but is impracticable for large trees, in forests and plantations. The author states that for the treatments to succeed, the first aphid colonies that settle on the tree after hibernation this takes place by the month of March in Italy should be primarily targeted.

In warm regions such as Africa, the aphid does not overwinter as an egg; instead parthenogenetic reproduction continues all year.

Cypress and juniper aphids. A subsequent study found that selection for resistance to aphid damage was unlikely to have adverse effects on economically important traits such as the height and diameter of the trunk Kamunya et al.

The aphids are very difficult to see and can easily be missed at quarantine inspection unless the inspector is alerted to their possible presence. Further details cupresi be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report.
