The effect of carmine spider mite [Tetranychus cinnabarinus] infestation on the physiological activities of cotton.
1989
Wu Kongming
A series of physiological activities of cotton damaged by carmine spider mite, Tetranychus cinnabarinus changed significantly. The intensity of cotton photosynthesis was reduced owing to the decreased chlorophyll contents and transpiration intensity and increased stoma resistance to gas exchange. The osmosis of leaf cell membrane, and the isoenzymes spectra of peroxidase and esterase were also changed. The contents of amino acids and soluble protein in cotton leaf were reduced as the damage of spider mite became heavier. The contents of most of the 17 amino acids, especially the glutamic acid, histidine, and turosine were decreased obviously, while the content of cysteine was increased.
