ABSTRACT Neochetina eichhorniae Warner and N. bruchi Hustache, biological control agents of Eichhornia crassipes (Martius) Solms-Laubach, are usually incapable of flight but occasionally develop indirect flight muscles enabling dispersal. This reportedly alternates with oogenesis and is reversible. We examined host quality as a possible explanation for

Toxic effect of herbicides used for water hyacinth control on two insects released for its biological control in South Africa [PDF]
The integrated control of water hyacinth, Eichhornia crassipes (Martius) Solms- Laubach (Pontederiaceae) has become necessary in South Africa, as biological control alone is perceived to be too slow in controlling the weed.

The effect of temperature on biological control of water hyacinth, Eichhornia crassipes (Pontederiaceae) in South Africa [PDF]
MSc., Faculty of Science, University of the Witwatersrand, 2011The behaviour and physiology of every insect, during all developmental stages, is largely determined by temperature. Metabolic rate, flight activity, nutrition, growth rate, oviposition and

Opportunities for classical biological control of weeds in European overseas territories [PDF]
European overseas territories are home to biodiversity and endemism of worldwide importance, vastly superior to that of continental Europe as a whole. They are, however, much more threatened by invasive species, including hundreds of alien invasive plant

The plastron theory was tested in adults of Neochetina eichhorniae Warner, 1970, through the analysis of the structure that coats these insects' integument and also through submersion laboratorial experiments. The tegument processes were recognized in three types: agglutinated scales with large perforations, plumose scales of varied sizes and shapes ...

Induced resistance in invasive plants might influence herbivore performance or preference, and hamper herbivore-based biological control management. Specialist weevils Neochetina eichhorniae Hustache (Coleoptera: Curculionidae) and N. bruchi Warner (Coleoptera: Curculionidae) are two herbivores commonly used to control Eichhornia crassipes (Mart ...
