RATE OF DEVELOPMENT, THRESHOLD (ZERO) OF DEVELOPMENT AND THERMAL UNITS FOR DIFFERENT STAGES OF MEALYBUG, Icerya seychellarum (WESTWOOD) AT DIFFERENT DEGREES OF TEMPERATURE.
Different biological features of Icerya seychellarum was studied under four different degrees of constant temperature on mango seedlings, Mangifera indica. Rate of development was 8.0, 2.3 and 1.9 days at 15oC for egg, nymphal and adult stages, respectively, while it was 23.8 , 40 and 3.9 days for the same stages, at 33oC. Hypothetical threshold (zero) of development was 9.2, 10.4 and 12.4oC for egg, nymphal and adult stages, respectively. Mean thermal units was 85.5, 429.3 and 384.3 degree/ days for egg, nymphal and adult stages, respectively.
