Water hyacinth (Eichhornia crassipes (Mart.) Solms-Laub.) remains a problem waterweed worldwide, for which biological control offers a sustainable solution. Under laboratory conditions, we investigated the interaction between two established weevil species Neochetina eichhorniae (Warner), Neochetina bruchi Hustache and the mirid Eccritotarsus ...

Water hyacinth, Eichhornia crassipes (Mart.) Solms (Commelinales: Pontederiaceae), is an important aquatic weed worldwide. Previous studies demonstrate that releases of Neochetina bruchi Hustache (Coleoptera: Curculionidae) provide biological control in many locations, but not all. Notably, N.

Control of Waterhyacinth by Neochetina bruchi (Coleoptera: Curculionidae: Bagoini) in Argentina
Environmental Entomology, 1983The first case of biological control of waterhyacinth, Eichhornia crassipes (Mart.) Solms, by the weevil Neochetina bruchi Hustache is reported from the Dique Los Sauces reservoir in La Rioja Province, Argentina. Four years after introduction of N. bruchi , its population had increased to 3.5 adults per plant; waterhyacinth was reduced from the usual ...

Abstract Neochetina weevils have potential as biocontrol agents for water hyacinth, an aquatic weed which seriously affects irrigation water supply in sugarcane, vegetables and other horticultural crop production in the Rift Valley of Ethiopia. A study was conducted on (i) the adaptability and duration of developmental stages of Neochetina weevils ...

Observations under field conditions in Bangalore showed that release of Neochetina eichhorniae and N. bruchi (Coleoptera: Curculionidae) brought about successful control of the water hyacinth in water bodies where the plants were free-floating. However, in situations where the plants were partly anchored, suppression of the weed was achieved only 8 ...

Environmental Entomology, 1986
Toxicities of commonly used water hyacinth herbicides and additives to water hyacinth weevils, Neochetina eichhorniae Warner and N. bruchi Hustache, were tested in the laboratory. Weevils were either sprayed while on water hyacinth plants or dipped directly into the compounds tested.

Biological Control, 2001
Abstract The potential effects of Beauveria bassiana, an entomopathogen, on the biological control agent of water hyacinth, Neochetina bruchi, were assessed. In bioassays, B. bassiana induced mortality of the eggs, larvae, and adults when the N. bruchi stages were either sprayed or dipped in conidia concentrations of 5 × 105, 5 × 106, 5 × 107, 5 ...

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. Hence, implementation of eco-friendly management option such as biological control is a mandatory.

Water hyacinth (Eichhornia crassipes (Mart.) Solms.)creates severe problems in the irrigationdistricts of Mexico, particularly in westernSinaloa. Therefore water hyacinth weevils(Neochetina eichhorniae Warner and N. bruchi Hustache), imported from the USA in1993, were used to initiate a biologicalcontrol program.
