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 ...

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 ...

Biological Control, 1999
Abstract The weevils Neochetina eichhorniae and N. bruchi were released in the USA for waterhyacinth control during the early 1970s and have since been used in many other countries. Although successful control has been reported, questions regarding the efficacy of these insects remain unresolved. This lack of consensus may be attributed to the subtle

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.

Abstract The integration of biological and herbicidal methods is advocated to manage waterhyacinth, but this can only be achieved when herbicides are nontoxic to the biocontrol agent. Therefore, laboratory experiments were conducted to determine the toxic effect of herbicides on the insect biocontrol agent, the waterhyacinth weevil, Neochetina bruchi ...
