Invasive Animals

Argentine ant

Linepithema humile

The Argentine ant invades urban and agricultural land, and undisturbed fynbos in the Western Cape. A small brown ant, reaching 2 – 3mm in length. Argentine ants feed on honeydew (from aphids and mealybugs) and protein (dead insects). Colonies have several queens and spread by budding. This species has been known to reduce indigenous ant diversity. Reduces the number of seeds produced by proteas.

Asian fruit fly

Bactrocera invadens

Asian fruit fly is the world’s worst destructive pest of fruit and vegetables. Of major concern is the increase in trade and tourism as this increases the risk of infested fruit being carried across South African borders. It is an offence to import plants and plant material into South Africa without authorisation. Luggage is frequently scanned or sniffed by sniffer dogs to detect fruit and other plant products.

Asian tiger mosquito

Aedes albopictus

A small to medium-sized mosquito with distinctive black and white body. Narrow white bands are prominent on the legs. The wingspan is 5,5mm. Known to transmit various diseases and pathogens, including West Nile virus, yellow fever virus, dengue fever and Chikungunya fever. It also transmits disease to animals.

Axis deer

Axis axis

Axis deer are semi-nocturnal, usually feeding for four hours after sunrise. Thereafter they seek out water and rest in the shade during the midday heat, returning to feed a few hours before sunset. They do not attempt to establish territories. 

Banana root borer

Cosmopolites sordidus

The banana root borer is a major pest of the banana plant and infests all types of bananas. The insect originated in Southeast Asia and has spread to all the important banana and plantain plantations in the world. It is not usually a pest in its area of origin.
