متن کاملBIOLOGICAL CONTROL Herbivore Adaptations to a Low-Nutrient Food: Weed Biological Control Specialist Spodoptera pectinicornis (Lepidoptera: Noctuidae) Fed the Floating Aquatic Plant Pistia stratiotes
Performance of the specialist herbivore Spodoptera pectinicomis (Hampson) was studied when fed the floating aquatic plant waterlettuce, Pistia stratiotes L. (Araceae). Plants were either collected from 6 populations in southern Florida or from plants grown with low or high fertilizer levels. Consumption of leaves with increasing toughness resulted in increased larval mortality (>80%); most mort...
متن کاملWater hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes) in the Great Lakes: playing with fire?
The Laurentian Great Lakes have been successfully invaded by at least 182 nonindigenous species. Here we report on two new species, water hyacinth Eichhornia crassipes and water lettuce Pistia stratiotes, that were found at a number of locations in Lake St. Clair and Detroit River during autumn 2010. Both species are commonly sold in the water garden and aquarium trade in southern Ontario and e...

متن کاملEffect of nickel-stresses on uptake, pigments and antioxidative responses of water lettuce, Pistia stratiotes L.
Water lettuce plants were exposed to various concentrations (0, 0.01,0.1, 1.0 and 10.0 ppm) of nickel as nickel sulphate in nutrient medium. The effect of graded nickel (Ni +2) concentrations on visible symptoms of toxicity, pigments (chlorophyll a, b and total) and antioxidative attributes were evaluated. Plants exposed to high nickel (1.0 and 10.0 ppm) showed visible toxicity symptoms, such a...
