Temperature Optima for Development of Neochetina eichhorniae and Orthogalumna terebrantis

The Florida Entomologist, 1977
Mottled waterhyacinth weevils, Neochetina eichhorniae Warner, and waterhyacinth mites, Orthogalumna terebrantis Wallwork, were tested for mortality, feeding, oviposition, and emergence at 4 temperature regimes, viz. 5-25@*, 10-30@*, 15-35@*, and 20-40@*C. Highest mortality for both species occurred at the 2 extreme regimes.

Host spectrum, reproduction, and survival of Neochetina eichhorniae (Coleoptera: Curculionidae) - A potential natural enemy for controlling water hyacinth (Eichhornia crassipes)

The Journal of Agriculture and Development, 2021
Neochetina eichhorniae (Coleoptera: Curculionidae) is a natural enemy of water hyacinth and its morphology as well as biology has been investigated previously. In this study, the host range of N. eichohorniae was examined using the following 7 groups of plants: Pontederiaceae (water hyacinth, Eichhornia crassipes; hastate-leaf pondweed, Monochoria ...

Damage byNeochetinaWeevils (Coleoptera: Curculionidae) Induces Resistance inEichhornia crassipes(Commelinales: Pontederiaceae)

Florida Entomologist, 2013
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 ...
