Lantana camara L. is one of the worst invasive alien species that are categorized worldwide. The objective of this review paper was to review the dispersal and threats posed by Lantana camara L. in Ethiopia and based on review results, to suggest management strategies that can bring solutions to the threats posed by the weed. Both biological characteristics of Lantana camara L. and its dispersal agents have contributed to the success of its dispersal. Even though Lantana camara L. is dispersed in other places within Ethiopia, Debrezeit, Dire Dawa, Harar and Somali are the hotspot areas for the weed. Biodiversity and potential agricultural loss, human and animal health problems and infestation in national parks are the identified threats that Lantana camara L. posed within the country. Utilization of Lantana camara L. for various purposes, prevention of its further dispersal into non-infected areas, use of fire, mechanical and biological control and awareness creation are the suggested management strategies that can bring solutions to the threats posed by the weed within the country.

Lantana camara Linn. (Family: Verbenaceae), an ornamental shrub, a noxious weed grows in many tropical and subtropical parts of world. The common name of this ornamental shrub is lantana, wild/red sage, bunch berry, locally known as “Barophulnoo”. The genus Lantana (Verbenaceae) as described by Linnaeus in 1753 contained seven species, six from South America and one from Ethiopia.

Abstract The present status of the imported and naturally occurring insects pests of Lantana camara L. a noxious exotic weed in Zambia, was determined by survey. Of the seven insect species imported in 1969–74, only Teleonemia scrupulosa Stål has become established in Zambia and occurs today all over the country. Two other neotropical lantana insects, namely Ophiomyia lantanae (Froggat) and Lantanophaga pusillidactyla Walk, have spread naturally into Zambia. In addition, 17 indigenous insect species were recorded as infesting lantana during the survey. The actual injuriousness of the insect complex to lantana was in all cases negligible, and it was concluded that insects will probably not contribute significantly to lantana control in Zambia.

Abstract In native forests in Queensland, more than 50 species of mites can be found on the leaves of the invasive weed Lantana camara , including two lantana specialists: the eriophyoid leaf vagrant Rhynacus kraussi and the lantana flower mite Proctolaelaps lobatus . Three exotic pests with broad host ranges are co‐invading native forests on lantana: the privet mite Brevipalpus obovatus; the passionvine mite Brevipalpus phoenicis; and the prickly pear spider mite Tetranychus desertorum . In south‐eastern Queensland, privet mite was present at three‐quarters of the sites sampled, even on isolated plants deep within national parks. A diverse fauna of mostly Australasian endemic natural enemies also colonise lantana; 37 species of predatory mites were identified (including 25 species of Phytoseiidae) and a pathogenic fungus was found attacking prickly pear spider mite in tropical Queensland. Therefore, largely without notice and with unknown consequences, several introduced agricultural pests have invaded native forests on a noxious weed and a host of native natural enemies have responded. The latter could be a severe problem for any mite introduced into Australia to control lantana.

Antitermitic effect of the Lantana camara plant on subterranean termites (Isoptera: Rhinotermitidae)
Abstract The insecticidal effects of Lantana camara L. (flowers, leaves, stems and roots) and the soil where lantana had been growing, on foraging activity and survival of the subterranean termites Coptotermes formosanus and Reticulitermes flavipes were examined in a 3‐week experiment. The soil in which lantana had been growing had no effect on termite tunneling and survival. Incorporation of chipped fresh lantana leaves and stems into soil had no effect on mortality but caused significant reduction in tunneling. The 5‐cm wide barrier of soil with lantana tissue incorporated effectively repelled groups of both species from penetrating the barrier and thus prevented infestation of a piece of wood on the other side of the barrier. C. formosanus was more sensitive in avoiding the barrier than R. flavipes . Leaves, stems and flowers were more repellent than roots. These results provide preliminary evidence that fresh‐cut lantana leaves, stems and flowers may have use as additives to garden mulches against termites.

Lantana camara is a flowering shrub of the family Verbenaceae, native to the Americas which has become a major invasive weed in the Palaeotropics; affecting both natural and agricultural ecosystems. It has been the focus of classical biological control for over a century but has proven to be a problematic target because of its high genetic diversity. Here, we report on an aggressive pathotype of the microcyclic rust Puccinia lantanae collected in the Amazonian rainforest, which – based on greenhouse screening – is damaging to a wide range of biotypes of the L. camara complex. Host-range testing within the Verbenaceae and related plant families, involving leaf clearing and staining, showed the pathotype to be highly specific to L. camara sensu lato but with detectable symptoms in several other verbenaceous species. These results, together with a taxonomic re-appraisal of Puccinia lantanae, are discussed in relation to the potential of the rust as a classical biological control agent of L. camara. We conclude that this pathotype of P. lantanae is a valuable addition to the biological control armoury and posit that it should be especially successful in humid forest situations.
