Optimization of Neochetina eichhorniae Warner and Neochetina bruchi Hustache for the management of water hyacinth, Eichhornia crassipes (Mart.) Solms in the Central Rift Valley lakes through the use of different nutrient levels in Ethiopia [PDF]

SINET: Ethiopian Journal of Science, 2022
Water hyacinth, Eichhornia crassipes (Mart.) Solms, is an alien invasive weed in Ethiopia that has been established in freshwater bodies. Eichhornia crassipes negatively affects water transportation, fishing and biodiversity among others.

Water hyacinth Eichhornia crassipes (Mart.) Solms-Laubach dynamics and succession in the Nyanza Gulf of Lake Victoria (east Africa): implications for water quality and biodiversity conservation. [PDF]

ScientificWorldJournal, 2012
This study, conducted in Nyanza Gulf of Lake Victoria, assessed ecological succession and dynamic status of water hyacinth. Results show that water hyacinth is the genesis of macrophyte succession. On establishment, water hyacinth mats are first invaded by native emergent macrophytes, Ipomoea aquatica Forsk., and Enydra fluctuans Lour., during early ...

Prioritising environmental invasive weeds of European concern for classical biological control: A reanalysis

Weed Research, Volume 63, Issue 4, Page 218-231, August 2023., 2023
Abstract Invasive alien plant species (IAPs) are causing significant negative impacts on agricultural production, threatened native species and ecosystems, the services they provide and public health thereby affecting European biodiversity and its economy. IAPs invade all types of natural and managed habitat and their impacts, through increased numbers

Abiotic and biotic influences on the performance of two biological control agents, Neochetina bruchi and N. eichhorniae, in the Sacramento-San Joaquin River Delta, California (USA)

, 2021
Variability in the effectiveness of biological control programs can be due to a myriad of abiotic and biotic interactions. Here, we explore these interactions in relation to the suboptimal biological control on the invasive water hyacinth, Pontederia ...

Problem of Water Hyacinth (Eichhornia crassipes (Mart.)) in Lake Tana (Ethiopia): Ecological, Economic, and Social Implications and Management Options

International Journal of Ecology, Volume 2023, Issue 1, 2023., 2023
Lake Tana is Ethiopia’s largest body of fresh water, covering approximately 3,200 km2. Despite its multidisciplinary applications in Ethiopia and neighboring countries, water hyacinth (Eichhornia crassipes (Mart.) Solms) is a significant problem in this large lake. This invasive weed first appeared in Lake Tana in 2011 and quickly spread to the water’s
