Eichhornia crassipes responses to Megamelus scutellaris feeding under nitrogen and temperature for control.
Supervisors: Dr Julie Coetzee & Prof Martin Hill
Chumakwande completed his honours with UFH in 2014, where he was working on Brassica oleracea L. var. capitata (cabbage) and testing the effects of various fertilizer applications on Bravicoryne brassicae’s reproduction and development.
Water hyacinth, Eichhorrnia crassipes (Mart.) Solms-Laubach (Pontederiaceae) is a free floating, perennial, and herbaceous aquatic invasive plant that originating from South Amazon basin, South America. The invasion has been problematic throughout the world and in Africa but has been efficiently controlled except for South Africa. Biological control has been proposed and proven to be the ideal control method with the use of Megamelus scutellaris among other insects and a pathogen. Megamelus scutellaris is the most recent agent release in South Africa, due to apparent inefficiency of other introduced agents.
For his Masters Chuma intends to determine the correlation between temperature and Eichhornia crassipes nutritional state on control with Megamelus scutellaris, in order to advance biological control. The study will carry forward existing literature to narrow down the loopholes in biological control pertaining to temperature and nutrition conditions.
