Since the s, stands of cypresses and junipers in many countries have been seriously damaged by C. Natural enemies Cinara cupressi is liberally coated in wax which discourages cuprssi predators.
Their multivariate analysis also demonstrated that Cinara sabinae might be partially identifiable using morphology. The aphids feed on the bark of small twigs and branches in the finara and lower parts of the main canopy Ciesla, It occurs in Europe, Asia, Africa and the Americas.
Datasheet Cinara cupressi sensu lato Cypress aphid.
Once the number of taxa has been clarified it may be possible to find more reliable means of identifying them using morphological characters.
Eggs are deposited in rough areas on twigs and foliage, where rthey overwinter. Cupresdi has been included in the List of the world’s worst invasive species.
Notes on Mulanje cedar – Malawi’s national tree. Close Find out more. The saliva they produce is phytotoxic and leads to necrosis in the phloem which subsequently results in the twig withering see pictures below. In the genus Cupressus, the most tolerant species were Cupressus torulosa, Cupressus funebris and Cupressus arizonica, whereas the most susceptible were Cupressus benthamii [Cupressus lusitanica var.
However, Kairo and Murphy found that the development threshold was as low as 0. Delfino MA; Binazzi A, The rostrum is relatively short, although that of the fourth instar nymph first image below is longer in relation to body length than that of the adult.
Similarly Pauesia juniperorum has been used in Chile. Ten families were recommended for use in breeding, to widen the genetic base of future forests in the region Mugasha et al. These observations should be repeated in younger trees and in different areas. Lachnidae when bred under laboratory condition.
Cypress aphid (Cinara cupressi sensu lato)
How does it spread? Loss of these plantations could have serious effects on Kenya’s domestic wood supply. Agarwala and Raychaudhuri, The distribution map includes records based on specimens of C. Arab Journal of Plant Protection, 18 1: The future of this potentially very valuable tree currently hangs in the balance, and a cinaara programme of re-planting and conservation is needed to ensure its survival in the wild.
Means of Movement and Dispersal Top of page The natural dispersal of cypress aphids is through the flight of the winged forms, which are produced a few times each year in response to overcrowding and environmental cues Kairo and Murphy, Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report.
From its initial introduction point in Malawi, Africa, it spread through southern and eastern Africa, where it caused extensive damage in eight countries Ciesla, ; Murphy et al. Annals of the Entomological Society of America, 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, In Chile affected native forest species include Austrocedrus chilensis and Fitzroya cupressoides Montalva et al.
It is also transported on imported plant material. Natural enemies of the aphid include parasitoid wasps in the genus Pauesiaand some of these have been considered for use in biological pest control.
Some aspects of the biology of Cinara cupressi Buckton Homoptera: Results with hybrid trees indicated that resistance breeding through hybridization might offer a viable long-term solution to the aphid problem.

Cupressus lusitanica was also a key agroforestry species and was widely planted for windbreaks, used as a source of fuelwood, and used for living fences and hedges. Observations on the impact of infestation on cupredsi tree species in the arboretum indicated that there is a wide range of tolerance between different species Obiri, Cinara cupressi apterae cuprsesi first picture below are mainly orange brown to yellowish brownwith blackish markings diverging back from the thorax.
There are two adult forms – winged and wingless.
