C. cuppressivora is a brownish soft-bodied aphid ranging from 2-5 mm in length, often with a grey waxy coating. Adults can be either winged or wingless. Usually, they occur in colonies on twigs and branches of infested tress. Adults produce young nymphs rapidly hence causing a rapid build-up in population. Reproduction occurs mostly by parthenogenesis and adults give birth to live nymphs. Three nymphal instars occur, lasting for about 11 days. Adults survive for a period of about 15 days and the entire lifespan extends over approximately 25 days. Table below shows the number of nymphal instars and developmental periods of C. cuppressivora, when reared on cuttings of J. bermudiana under laboratory conditions (25°C and 75% RH).

Damage The aphid exploits a wide range of feeding sites varying from green branches to woody stems. Damage mainly occurs by sap feeding hence causing yellowing and browning of foliage. The saliva produced is phytotoxic and leads to necrosis in the phloem resulting subsequently in twig withering. Feeding retards new growth and causes desiccation of the stems with a progressive dieback of heavily infested trees. The overall effect ranges from partial damage to eventual death of the entire tree depending on the severity of the infestation. Death can occur within tree months in case of severe infestation. Large amount of honeydew is also produced favouring growth of sooty mould which hereby hinders photosynthesis and gas exchange.
Other species of Cinara Cinara cronartii and C. juniperi have become important pests of pine in many African and Latin American countries. Loss of commercial plantations could have serious effects on the domestic wood and timer supply of many countries. Dispersal Cypress aphids are easily transported through planting materials, foliage and woody stems.
Host Range C. cuppressivora has a wide host range. It attacks cypresses, cedars and junipers. Worldwide, it feeds on various trees from the following genera: Cupressus, Juniperus, Thuja, Callitris, Widdringtonia, Chamaecyparis, Austrocedrus and the hybrid Cupressocyparis.
The pest has probably originated from the Middle East region where Cupressus and Juniperus species occur naturally. It is also present along the margins of Western Europe, North India, Africa (Burundi, Congo, Kenya, Ethiopia, Malawi, Morocco, Tanzania, South Africa, Uganda, ZImbabwe), Yemen, Colombia, North (Canada, USA) and South America (Brazil, Colombia).
