Survival of the mirid Eccritotarsus catarinensis as influenced by Neochetina eichhorniae and Neochetina bruchi feeding scars on leaves of water hyacinth Eichhornia crassipes

BioControl, 2006
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 turbidity affects the establishment of Neochetina eichhorniae (Warner) (Coleoptera: Curculionidae): Implications for biological control of water hyacinth

Environmental Research, 2023
Water hyacinth is the target of nine biological control agents in South Africa including Neochetina eichhorniae (Warner) and Neochetina bruchi (Hustache) (Coleoptera: Curculionidae). These two weevils have also been released against water hyacinth in Rwanda, but failed to control the weed invasion, possibly due to high turbidity in the country's water ...

Observations on the effect of the weevils Neochetina eichhorniae Warner and Neochetina bruchi Hustache on the growth of water hyacinth

Hydrobiologia, 1984
Water hyacinth Eichhornia crassipes (Mart.) Solms. is an aquatic weed that infests most of the White Nile system in the Sudan. Serious economical and ecological problems are caused by this weed. The two weevils Neochetina eichhorniae and Neochetina bruchi were imported and released in an attempted biological control against the weed.

Effects of Herbicide Application on Mortality and Dispersive Behavior of the Water Hyacinth Weevils, Neochetina eichhorniae and Neochetina bruchi (Coleoptera: Curculionidae)

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.

Age and Phytochemical Composition of Waterhyacinth (Pontederiaceae) Leaves Determine their Acceptability to Neochetina eichhorniae (Coleoptera: Curculionidae

Environmental Entomology, 1991
Behavior of the weevil Neochetina eichhorniae Warner, a specialist herbivore, varied with leaf age of waterhyacinth ( Eichhornia crassipes (Mart.) Solms-Laubach [Pontederiaceae]). In the field, adult feeding decreased as the leaves aged. Accrued feeding damage on 8-d-old leaves was only about 60% of the sum of two respective sets of 4-d-old leaves ...
