“…The third promising candidate is Psigida walkeri (Grote) (Lepidoptera: Citheroniidae), a native of Brazil. The larvae of the moth can cause considerable damage by feeding on leaves, tender stems, flower buds and tender seed pods of M. diplotricha [75]. Although, attack by P. walkeri can prevent flowering and seed production, the agent was not released in Australia because it fed on Acacia and Neptunia plants [14].…”

Mimosa diplotricha is an invasive perennial, scrambling, thorny, leguminous shrub of neotropical origin widely acknowledged as a major economic, agricultural and ecological burden in its introduced ranges. Although the plant is thought to have been present in Nigeria for well over two decades, its mode and time of introduction is uncertain. In spite of the continuing spread of, and the menace caused by M. diplotricha in Nigeria, no attempt has been made to map the distribution of the plant countrywide. Therefore, we conducted a countrywide survey between 2007 and 2009, sponsored by the Weed Science Society of Nigeria (WSSN) to determine the spread and status of Mimosa diplotricha in Nigeria. A further objective of this paper was to review literatures on Mimosa diplotricha in Nigeria and elsewhere to enable comparison. In this paper, we report on the spread, distribution and problems of Mimosa diplotricha in Nigeria based on the field monitoring surveys conducted. The distribution of this invasive plant in Nigeria has been mapped and is presented together with its ecology and problems being caused. Since the early 1990s, the weed has started to spread and invade many parts of the country causing significant damage to many natural and semi natural ecosystems. The different control options used by farmers to control Mimosa diplotricha in Nigeria are discussed. Based on the successful control of this invasive plant using the biocontrol agent, Heteropsylla spinulosa in countries such as Australia and Papua New Guinea (PNG), we discussed the biological control prospects for the management of Mimosa diplotricha in Nigeria. Such control attempts stands to benefit from international collaborations between Nigerian institutions and a host of others in Australia, PNG and/or Brazil. Finally three major causes for the massive and continuing spread of this weed in Nigeria are presented with recommendations for the Nigerian government and institutions to: 1) formulate policies and legislations regarding the control and management of invasive alien plant species which is currently nonexistent; 2) enlighten the general public on the dangers of invasive alien plant species such as Mimosa diplotricha; and 3) initiate actions such as early detection and rapid response (EDRR) and biological control in order to prevent further spread of, and invasion by invasive plant species including Mimosa diplotricha.

“…Several species in the Mimosa genus have been identified as invasive weeds, especially in the southern hemisphere (Vitelli et al, 2001). First identified in Brazil, M. pudica is a small short-lived shrub that has become a pan-tropical weed (Howard, 1988).…”

The aim of the study was to evaluate the potential impact of grazing on the control of Mimosa pudica, a ligneous weed species that invades grasslands in French Guiana. Three experiments were conducted in a glasshouse to test the potential impact of: (i) shading by testing different Photsynthetically Active Radiation (PAR) fluxes on seedlings and (ii) cutting of juveniles, at three stages of development, on their survival, flowering rate and nutritive value as measured by the mass:length ratio of stems and by branching processes. A significant mortality rate (0AE20) was obtained only for seedlings at the cotyledon stage when the PAR flux was reduced proportionately by 0AE83. Shading reduced both flowering rate and mass:length ratio of stems. For seedlings at the cotyledon stage, the flowering rate decreased from 0AE85 for the control to zero for the low light treatment (0AE13 of PAR flux of the control treatment). The mass:length ratio of stems of seedlings in the low light treatment was reduced to 0AE20 of that of control seedlings, at the fifth-leaf stage. Cutting treatment had no effect on mortality of juvenile plants whatever the size of the juvenile plant. The proportion of juvenile plants flowering was high for all cutting treatments. It is suggested that regular, but not continuous grazing, could maintain a dense sward to limit recruitment by seedling establishment and seed production, and maintain branched and juvenile plants with a high-nutritive value at the seedling stage.
