Red mite on citrus: Experiments designed to measure damage give bases for further studies
by Randolph T. Wedding, Louis A. Riehl, Lee R. Jeppson
| Full text HTML  | PDF  
Attempts to measure the effects of mite damage on various physiological processes in citrus plants—particularly the leaves—in field, greenhouse and laboratory experiments have added to the relatively little available information concerning the effects of red mite feeding.
