Life Cycle and Pupation Site Preference of Neochetina eichhorniae Warner (Coleoptera: Curculionidae) on Water Hyacinth in Nigeria

Nigerian Journal of Entomology, 2005
The life cycle and pupation site preference of Neochetina eichhorniae were studied in two outdoor experimental aquaria. The results showed that the period take for the egg hatch to larva, was 6.95±0.83 days. The larvae had three instars I. 11.5± 1.20 days: instar II, 12.5±1.88 days and instar III. 49.0±2.21 days.

Pre-release evaluation of Neochetina weevils potential for the management of Eichhornia crassipes [Mart.] Solm. In the Rift valley of Ethiopia

2016
The present study aimed at evaluating the host-specificity, potential efficacy and optimum densities of the two weevils (Neochetina bruchi and N. eichhorniae) as water hyacinth control agents in the Rift Valley of Ethiopia. Density-plant damage relationship was monitored for two years (2012 to 2014) in a factorial experiment by involving the two ...

The pathogenicity of an Australian isolate of Acremonium zonatum to water hyacinth, and its relationship with the biological control agent, Neochetina eichhorniae

Australian Journal of Agricultural Research, 1987
The first description of Acremonium zonatum on water hyacinth in Australia is made. Its pathogenicity was studied as part of the search for a microorganism already present in Australia which could be developed as a mychoherbicide to supplement the arthropod biological control programme in this country. Following inoculation with A.
