The bud-galling wasp Trichilogaster acaciaelongifoliae could be successfully introduced as a biological control agent of the invasive alien plant Acacia longifolia in coastal areas of Portugal. Acacia longifolia (Sydney golden wattle) is a plant native to eastern Australia that has become invasive in several areas worldwide, including California. The leaves are replaced by undivided leaf-like phyllodes that are 50-250 mm long and (4)10-35 mm wide and each face has 2-4 prominent longitudinal veins. One of these, Trichilogaster acaciaelongifoliae Froggat, has been important in the biological control of Acacia longifolia (Andrews) Willdenow in South Africa (Dennill & Donnelly, 1991).

In New South Wales it is common along the tablelands and coastal areas where it is situated in various habitats including foredunes and is usually a part of sclerophyll woodland or coastal heath and scrub communities. It produces a lot of nitrogen-rich litter, which promotes change in soil composition (carbon and nutrients, mainly nitrogen) and microbiology. [13] It is heavily used at present in Southern California as a street canopy tree, as it grows fairly quickly (reaching a height of five meters within a year or two of planting), tolerates drought, and is resilient even to the particularly brutal pruning practices associated with low-cost tree services. Acacia cyclops (coastal wattle) is similar but has phyllodes that are generally smaller, lighter and slightly falcate; the flowers are arranged in globular flower heads, the pod is compressed and the funicle is scarlet and completely encircles the seed. Care should be taken to cut the trunk as close to the ground as possible by using manual and/or mechanical equipment. We assessed, under greenhouse conditions, the herbicidal effect of phytotoxic manures from Acacia dealbata and Acacia longifolia applied to soil at different doses (1.5 and 3% w/w) on maize growth, some accompanying weeds, and the physiological profile of soil microbes.

Monitor site for recruitment from seedbank. The seeds are dispersed by animals, mainly birds and ants, which lead to the formation of invasion foci. Sydney golden wattle is well suited for low maintenance areas such as road batters, will grow in a range of soil types and is frost hardy. It is useful for securing uninhabited sand in coastal areas, primarily where there are not too many hard frosts. Older plants can be ringbarked. Mais publicações sobre esta espécie neste menu.

Acacia longifolia grows in a variety of habitats, including nutrient-poor ecosystems - this is thought to be due, in part, to its ability to fix nitrogen (Werner et al. 1. sophorae). On the right side, the radial line shows The effect on the trees has been described as drastic seed reduction (typically over 90%) by galling of reproductive buds, and indirect debilitation of the affected plant by increased abscission of inflorescences adjacent to the growing galls. It should be guaranteed that no stumps and main roots are left in the ground. Willd. [10] The tree's bark has limited use in tanning, primarily for sheepskin. Hegnauer, Robert (1994).
