“…This freshwater bivalve presents a planktonic larval stage (Darrigran & Ezcurra de Drago, 2000), which is its main way of propagule pressure (e.g., Simberloff, 2009;Ernandes-Silva et al, 2016b), while the adult form is normally related with fouling of individuals on the substrate (Darrigran & Damborenea, 2009). Thus, the wide distribution of L. fortunei in flooding areas might be related to high water periods (see Ernandes-Silva et al, 2016b), when connectivity increases among environments (Junk et al, 1989) and facilitates the displacement of both larvae by passive dispersion in the water and adults fouling at vessels traffic (Darrigran & Damborenea, 2009).…”

Aim:To verify the temporal dynamics of Limnoperna fortunei larval stages and to identify the main environmental variables driving the larval density patterns in an area highly impacted by reservoirs. Methods: Samplings were performed quarterly, from February to December 2014, in 10 transects along to the Paraná River main channel. For each sample site, 100 L of water were filtered. The filtrated was fixed in alcohol 80%, and the larval stages were counted and classified under the optical microscope. Concomitant to biological collections we took some of the main water variables. We performed a Redundancy Analysis (RDA) in order to summarize the variations in densities of larval stages in relation to the main physical and chemical water variables. Results: We found a total of 200,590 L. fortunei larvae, in which 83.6% were identified as the initial stages. The most abundant months in L. fortunei larvae were December and February. The first two axes of RDA sum up 96% of the total data variation, and the most significant environmental variables explaining variations in larval densities were: water temperature, total nitrogen, electrical conductivity, phosphate, dissolved oxygen, depth and ammoniac ion. The warmer months were influenced by the major values of water temperature and depth, besides the higher densities of all larval stages. Conclusions: Our results indicate that L. fortunei reproduction follows a general pattern throughout the upper Paraná River floodplain, what seems to occur mainly between February and December. Thus, we suggest that measures for the L. fortunei control should be done during low-density periods (i.e., April to August), when the water level is low, and consequently, the dispersion of this species might be limited.Keywords: area of environmental preservation; propagule pressure; golden mussel; reproduction.Resumo: Objetivo: Verificar a dinâmica temporal dos estágios larvais de Limnoperna fortunei, e identificar as variáveis ambientais direcionadoras desses padrões, em uma área altamente impactada pela construção de reservatórios.

“…In 1998, the mussel was found in both the Salado River in Paraguay and the Paraguay river in Brazil (Darrigran et al 2000). Paraguay River is a major tributary of the Paraná, which is one of the largest wetlands in the world and is considered an area of great ecological importance.…”

Concerns have been raised about the significant biofouling and environmental problems caused by the large numbers of Limnoperna fortunei clinging to water intake facilities. This review first provides a summary of the occurrence of L. fortunei in typical regions including China, South America, and Japan. Furthermore, this article provides a comprehensive overview of the biological traits, risks, and control of L. fortunei. Importantly, the planktonic larval stage is a critical period for the expansion of L. fortunei. Its biofouling process mainly relies on the adhesion of byssus to substrates. Various physical and chemical methods have been proposed and used to control L. fortunei. Among these methods, sodium hypochlorite has been shown to be effective in preventing the adhesion of L. fortunei by dissolving its byssus at much lower concentrations. Overall, effective and environmental-friendly antifouling strategies are still rare, particularly in drinking water treatment systems, and are encouraged to develop in future studies. This review not only provides a comprehensive understanding of L. fortunei but also helps to guide the prevention and control of L. fortunei.

“…The main phases of invasion of IAS include an introduction, establishment, and spread (Darrigran et al, 2015). IAS may be introduced intentionally as biological control insects or maybe unintentional which is driven by global trade, tourism, and travel, also known as '3T' which results in movement of pests across different regions (McNeely et al, 2001).…”

Nepal faces a significant risk of invasive species posing a direct threat to food security and native biodiversity. With the potentiality of causing a considerable loss in yield and quality, invasive pest species can lead to significant damage in the Nepalese agricultural sector. Fall armyworm is a polyphagous, transboundary invasive pest that invaded Nepal in August 2019. They have a wide host range, the potentiality to establish rapidly and are highly migratory. Maize is the major host of fall armyworm which comes second in terms of production and area cultivated in Nepal. Spread and establishment of this pest are enhanced during the monsoon season of the country with favorable climate and temperature. This review presents an introductory pathway of the invasive pest, biology, lifecycle, status, and management of fall armyworm in Nepal. Integrated pest management can be the best approach for the management of this pest. Control of this invasive pest requires early monitoring, scientific research, and management strategy with awareness, knowledge, and technical support to Nepalese farmers.
