Genetic diversity, population structure and gene flow in native populations of a proposed biocontrol agent (Cornops aquaticum) [PDF]

Biological Journal of the Linnean Society, 2008
The semiaquatic grasshopper Cornops aquaticum is native to South America, with a distribution as far south as the Argentinean pampas and as far north as the Gulf of Mexico. This grasshopper is being proposed as a form of biological control agent for the invasive aquatic macrophyte (Eichhornia crassipes) in South Africa. The results of a molecular study

Eichhornia crassipes (Mart.) Solms: Uses, Challenges, Threats, and Prospects [PDF]

The Scientific World Journal, Volume 2020, Issue 1, 2020., 2020
Water hyacinths pose serious challenges to humanity and the environment. Considering the enormity of the menace associated with the growth and spread of the plant and the difficulty in achieving a single, generally acceptable control method, it is becoming increasingly imperative to explore the potentials of the plant.

Performance and Feeding Preference ofCornops aquaticum(Orthoptera: Acrididae) onEichhornia crassipesand Crop Plants in Native Area [PDF]

Journal of Orthoptera Research, 2014
Abstract The semiaquatic grasshopper Cornops aquaticum Bruner, which is highly specific of Eichhornia crassipes (Pontederiaceae), constitutes one of the most abundant herbivores in the Neotropical wetlands and a possible biological control agent of this weed in South Africa.
