Abstract: At laboratory conditions of 25℃ and 75-85% RH, the developmental duration of egg, larva, protonymph, and deutonymph of A. eharai were 2, 1, 1, and 1 days, respectively. The total duration of the immature development was 5 days. A female adult could oviposit an average of 41.6 eggs in its life span. The average longevity was 55.5 days for the females and 39.9 days for males. The potential capacity of controlling Panonychus citri by A. eharai was discussed based on results of the experiments.
