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 ...

Persebaran agens hayati Neochetina spp. (Coleoptera: Curculionidae) di jawa barat dan DKI jakarta [PDF]

Jurnal Entomologi Indonesia, 2017
The establishment of Neochetina spp. as biocontrol agent of waterhyacinth are related to the weevil’s ability to disperse and to increase their population sizes. The objective of this research was to study the distribution and abundance of Neochetina spp.

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

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

A Comparison of Regression Tree Approaches to Modelling the Efficacy of Water Hyacinth Biocontrol Using Multitemporal Spectral Datasets

Journal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018
Water hyacinth (Eichhornia crassipes) is an exotic plant species that is effectively controlled by Neochetina spp. weevils. This study is aimed at determining if spectroscopic data may be utilized to predict insect‐induced stress on water hyacinth plants.
