Abstract

Carvalhotingis visenda (Hemiptera: Tingidae) is the first biological control agent approved for release against cat's claw creeper Macfadyena unguis-cati (Bignoniaceae) in Australia. The mass-rearing and field releases of C. visenda commenced in May 2007 and since then more than half a million individuals have been released at 72 sites in Queensland and New South Wales. In addition, community groups have released over 11,000 tingid-infested potted cat's claw creeper plants at 63 sites in Queensland. Establishment of C. visenda was evident at 80% of the release sites after three years. The tingid established on the two morphologically distinct 'long-pod' and 'short-pod' cat's claw creeper varieties present in Australia. Establishment was more at sites that received three or more field releases (83%) than at sites that received two or less releases (73%); and also at sites that received more than 5000 individuals (82%) than at sites that received less than 5000 individuals (68%). In the field, the tingid spread slowly (5.4 m per year), and the maximum distance of C. visenda incidence away from the initial release points ranged from 6 m to approximately 1 km.
