“…For example, climate (McClay, 1996;Byrne et al, 2002Byrne et al, , 2003, top-down factors (e.g., predators and parasitoids) (Goeden & Louda, 1976;Kluge, 1994;Manrique et al, 2011), and plant factors such as genetic dissimilarity, plant morphological variations, or biotype incompatibility (Dray et al, 2004;Simelane, 2006;Wheeler, 2006;Baars et al, 2007) have been suggested to deleteriously influence the survival, development, population dynamics, as well as the establishment of biological control agents. The success of such biological control agents are sometimes constrained by a multiplicity of biotic and abiotic factors that may limit their efficacy and even result in the failure of some agents to establish.…”

The effect of host plant dissimilarity on insect preference and performance was tested using two morphological forms of Chromolaena odorata (L.) King & Robinson (Asteraceae) (one from Florida, USA, another from South Africa), and a specialist herbivore, Pareuchaetes insulata (Walker) (Lepidoptera: Erebidae: Arctiinae) from Florida, USA, that was introduced as a biological control agent in South Africa. Although this insect did establish at one site, of some 21 sites at which over 800 000 individuals were released, its population level in the field has remained low after an initial outbreak in 2006. To explain the poor performance of P. insulata, we hypothesised that P. insulata larvae prefer Floridian C. odorata to the southern African C. odorata, which is morphologically and probably genetically distinct, and that larvae reared on Floridian C. odorata should have higher fitness and performance. We tested this by comparing insect performance metrics on each of the two plant forms in laboratory experiments. Apart from pupal mass, which was significantly greater on southern African C. odorata, P. insulata performance metrics were similar on both plant forms; there were no significant differences in total leaf area consumed, egg and larval development, immature survival rates, feeding index, host suitability index, growth index, and fecundity between the Floridian and southern African C. odorata plants. In sum, we could not demonstrate that differences in plant forms in C. odorata are responsible for the poor performance of P. insulata in South Africa.

Pristine tropical ecosystems are currently suffering under extreme demographic pressure. This has led to habitat destruction and disturbances, an important precondition for the invasion of exotic species into pristine ecosystems, with detrimental effects on biodiversity. In this study, we analysed the chronology of land cover changes along rivers in south-eastern Kenya using historical aerial photographs and current aerial pictures taken from a drone. We assessed quantity and quality of riparian thickets along these rivers in 1961, 1980 and 2015/ 2016 and analysed effects of fundamental land cover changes on arthropod abundance and diversity. Our data show effects from demographic pressure by the increasing number of human settlements rising by 425% from 1961 to 2015/2016 (i.e. from 36 to 189 settlements). 58.5% of the land surface originally covered by pristine riparian forests was cleared and transformed into agricultural land. After clearance and agricultural usage it frequently became fallow land and was invaded by the exotic shrub species Lantana camara. While the total coverage of riparian vegetation did not change over time, its quality declined dramatically. Currently 36.6% of the cleared pristine riparian forest is covered by L. camara thickets, and only 22.5% of the pristine riparian forest has remained unchanged over time. This modification of the vegetation structure impacts biodiversity. The abundances of three guilds of arthropods significantly differed between pristine and L. camara-dominated riparian vegetation, with herbivorous arthropods and ants being more abundant in pristine than in L. camara-dominated vegetation. Our data show that habitat destruction and disturbance is the prerequisite for subsequent invasion by exotic plant species, having a strong effect on species composition and diversity at higher trophic levels.

“…The petiole-galling weevil, Coelocephalapion camarae Kissinger when introduced in South Africa it supplemented the biological control programme against the invasive varieties of L. camara L. The adults are highly selective in their choice of leaf-petioles as their oviposition site and the emerging larvae burrow and disrupt the transport of water and nutrients to and from the leaf, causing it to desiccate. These studies suggest that C. camarae could make a valuable contribution to the biocontrol programme against L. camara (Baars et al 2007). Salbia haemorrhoidalis and Hypena laceratalis are considered to significantly reduce the growth and reproductive rates of L. camara (Baars 2003).…”

L. camara is a terrible weed, exerting huge detrimental effect on biodiversity. Its leaves and flowers contain toxins, lantadene A and B, so unfit for herbivory by ruminants. This weed stunts the growth of neighbouring plants owing to the allelopathic effect of its root leachate. The seeds tide over adverse period and germinate when favourable conditions prevail. Further, pruning makes the thicket denser. Almost all removal strategies of this weed have been unsuccessful so far. So, management of this weed by utilization is required. Recent studies have reported that L. camara improves soil quality by enriching it with nitrogen, exhibits termiticidal effect, acts as lignocellulosic substrate for cultivation of edible mushrooms, acts as potential insecticide and fumigant for grains storage against weevils, antifungal agent, herbicide against water hyacinths. L. camara has bioactive ingredients exhibiting anticancer, antiulcerogenic, hypolipidemic, larvicidal and anti-inflammatory activity. L. camara fibre has been reported to be suitable candidate as reinforcement in biomaterials. Also, this plant extract is effective in bovine dermatophilosis therapy. L. camara has also immense industrial importance, as a source of oleanolic acid and carboxymethylcellulose. L. camara biomass can be implicated as a substrate for bioethanol and biogas production. This invasive weed can also serve as livelihood options, as the woody twigs can be utilized for aesthetic and durable furniture making apart from the use as firewood. The latest published papers on the novel uses of L. camara have been reviewed, with the objective of providing a thrust to weed management by utilization.
