The plant has widespread around the world. Clatworthy and Harper (1962) studied the competition among three species of duckweed, Spirodela polyrrhiza, Lemna gibba, Lemna minor and, the single temperate species of Salvinia, S. natans. Because of this, although both species are active in the temperature range of 16° to 30° C, causing more damage at the higher temperature, it is concluded that the weevil alone, or in combination with the moth, will readily control salvinia north of Brisbane but that the moth alone will not" (Parsons and Cuthbertson, 1992; pp. We studied the combined effects of nutrient loading and increased temperature on the competition between the potentially invasive free-floating Salvinia natans (L.)
