Eichhornia, commonly called water hyacinths, was a polyphyletic genus of the aquatic flowering plants family Pontederiaceae. Since it was consistently recovered in three independent lineages, it has been sunk into Pontederia, together with Monochoria. Each of the three lineages is currently recognized as subgenera in Pontederia:
Lythrum salicaria or purple loosestrife is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the family Primulaceae. Other names include spiked loosestrife and purple Lythrum.
The Crambidae are the grass moth family of lepidopterans. They are variable in appearance, the nominal subfamily Crambinae taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies include brightly coloured and patterned insects which rest in wing-spread attitudes.
Pontederiaceae is a family of flowering plants.
Kwan Phayao is a lake in Phayao Province, northern Thailand. Kwan, a word from the northern Thai language, means 'lake' or 'large swamp'. The shape of the lake is a nearly-half-circle-moon shape. Phayao Lake is the largest freshwater lake in the northern region and the fourth largest in the country, with a depth of 1.5 metres, and covers an area of about 1,980 hectares. There are about 50 species of fish in Phayao Lake.
Black vine weevil is an insect native to Europe but common in North America as well. It is a pest of many garden plants.
The mottled water hyacinth weevil, Neochetina eichhorniae, is a beetle that has been introduced as a biological pest control herbivore agent to waterways and lakes in countries worldwide to control the spread of the invasive noxious weed species Eichhornia crassipes, the water hyacinth, an aquatic plant native to the Amazon basin.
Diaprepes abbreviatus is a species of weevil that is native to the Caribbean, where in Spanish it is colloquially called chichí. It is an agricultural pest in several Caribbean countries. In 1964 this weevil was accidentally introduced in the US, state of Florida, where it is at present a major pest of citrus. It was first discovered in southern California in 2005, where it is a pest of citrus, avocado, and nursery stock. It is also known to infest sugarcane, tuber-bearing crops such as potatoes, and ornamental plants. Common names for the insect include diaprepes root weevil, citrus root weevil and sugarcane rootstock borer weevil.
Pontederia crassipes, commonly known as common water hyacinth, is an aquatic plant native to the Amazon basin, and is often a highly problematic invasive species outside its native range. It is the sole species of Pontederia subg. Oshunae.
Alem Tena is the town in central Ethiopia. It is the administrative center of Bora Woreda in the Misraq Shewa Zone of the Oromia Region. It has a latitude and longitude of 8.30°N 38.95°E with an elevation of 1,611 meters.
Harike Wetland also known as "Hari-ke-Pattan", with the Harike Lake in the deeper part of it, is the largest wetland in northern India in the border of Tarn Taran Sahib district and Ferozepur district of the Punjab state in India.
Niphograpta is a genus of moths of the family Crambidae. It contains only one species, the water hyacinth moth. It is native to the Amazon basin, but has been introduced in North America, Africa and Australia to control the spread of water hyacinth.
Lilaeopsis masonii is a species of flowering plant in the family Apiaceae known by the common names mudflat quillplant and Mason's lilaeopsis. It is endemic to California, where it is known only from the Sacramento-San Joaquin River Delta and nearby shores of San Francisco Bay.
Eccritotarsus catarinensis is a species of plant bug from Santa Catarina, Brazil. It is a sap-feeding mirid that removes a considerable amount of chlorophyll from water hyacinth.
Pontederia azurea is a water hyacinth from the Americas, sometimes known as anchored water hyacinth. It is the type species of Pontederia subg. Eichhornia, which was previously recognized as part of the polyphyletic genus Eichhornia. It is of some interest as an aquarium plant.
Samea multiplicalis, the salvinia stem-borer moth, is an aquatic moth commonly found in freshwater habitats from the southern United States to Argentina, as well as in Australia where it was introduced in 1981. Salvinia stem-borer moths lay their eggs on water plants like Azolla caroliniana, Pistia stratiotes, and Salvinia rotundifolia. Larval feeding on host plants causes plant death, which makes S. multiplicalis a good candidate for biological control of weedy water plants like Salvinia molesta, an invasive water fern in Australia. However, high rates of parasitism in the moth compromise its ability to effectively control water weeds. S. multiplicalis larvae are a pale yellow to green color, and adults develop tan coloration with darker patterning. The lifespan, from egg to the end of adulthood is typically three to four weeks. The species was first described by Achille Guenée in 1854.
Water hyacinth has become a major invasive plant species in Lake Victoria and while it is native to the continent of South America, human activity has introduced the greenery to Lake Victoria, where it is claimed to have negatively affected local ecosystems.
Salvinia minima is a species of aquatic, floating fern that grows on the surface of still waterways. It is usually referred to as common salvinia or water spangles. Salvinia minima is native to South America, Mesoamerica, and the West Indies and was introduced to the United States in the 1920s-1930s. It is classified as an invasive species internationally and can be detrimental to native habitats. This species is similar to but should not be confused with giant salvinia, Salvinia molesta.
Cornops aquaticum is a semiaquatic species of grasshopper native to the Neotropics, from southern Mexico south to central Argentina and Uruguay. It feeds and breeds exclusively on members of the aquatic plant family Pontederiaceae, especially water hyacinth, and is being investigated as a possible biological pest control agent for the water hyacinth in countries where that plant is invasive.
Neochetina bruchi, the chevroned waterhyacinth weevil, is a species of marsh weevil in the beetle family Brachyceridae. It is found in North America and Africa.
