Gramine toxicity
WebGramine Toxicity to BPHs To determine whether gramine is toxic to rice BPHs, we designed artificial diets containing various concentrations of technical grade gramine (purchased from Kingsley and Keith LTD, UK) and fed BPH nymphs (second to third instar, unless otherwise indicated) with these diets for 24, 48, 72 and 96 hours. WebGramine Toxicity Gramine killed S. avenae when the insect was fed with the artificial diet containing higher concen-trations of the alkaloid (Fig. 1). After 72 h of feeding, S. avenae mortality followed in a dosage-dependent manner. The LC 50 was determined to be 1.248 mM (range 0.947– 1.743 mM). Effect of Gramine Enzyme Activity Total ...
