Solms-Laub.) (Pontederiaceae) https://vital.seals.ac.za/vital/access/manager/Repository/vital:5940 1.00) in BION® treated plants, reflecting increased weevil preferences for SAinduced water hyacinth plants. This concluded that SA-mediated defences are not effective against insect herbivory in water hyacinth plants, but are in fact palatable to insect herbivores, which reflects ecological and physiological costs of SA-mediated defences (pathogen defences) in water hyacinth. Biochemical analyses of leaves exhibited increases in nitrogen content in BION® treated plants. These elevated levels of nitrogenous compounds account for the increases in mirid and weevil preferences for BION® treated plants. The increases in nitrogenous compounds are probably structural proteins (e.g. peroxidises), because leaves treated with BION® increased in toughness, but only when exposed to herbivory. Regardless, insect herbivory was elevated on these leaves, probably because the nitrogenous compounds were nutritionally viable for the insects.]]> Thu 13 May 2021 03:55:03 SAST ]]> Comparisons of the thermal physiology of water hyacinth biological control agents: predicting establishment and distribution pre-and post-release https://vital.seals.ac.za/vital/access/manager/Repository/vital:35446 Sat 09 Sep 2023 09:41:46 SAST ]]>
