Popis:	Citrus snow scale development was studied under 9 combinations of constant temperature and relative humidity. An effect of temperature and relative humidity on the rate of development was observed. Optimal temperatures for development ranged between 25 and 38°C and developmental thresholds were estimated at 12°C. There were no differences in developmental time between sexes, nor on values of sex ratio between temperatures. Development on grapefruit leaves reported here was faster than that reported previously for development on lemon fruits. A nonlinear model of development was fit to the stage duration data and a gamma distribution model was fit to the mortality data.
