Six studies were conducted to quantify the relationship between fruit surface damage of `Hamlin' orange. Citrus sinensis, and population density of the citrus rust mite, Phyllocoptruta oleivara (Ashmead). over time, the damage rate per mite-day increased in sigmoid fashion mainly as a result of a sigmoid increase in cumulative mite-days. The sigmoid increase in cumulative mite-days resulted from the single-peaked, more or less symmetricallyshaped mite population growth. Increasing fruit maturity increased susceptibility to mite feeding. this was indicated by a decline in mite-days required to cause a given percentage of surface damage as fruit maturity increased. Tree age and grove location did not seen to have obvious effect on the general trend in damage ra te. A mathematical model was developed to describe the relationship between cumulative damage and cumulative mite-days. the model could be used to predict fruit surface damage based on mite population date. |
