Since 1993, the occurrence of Brevennia rehi (Lindinger) has evolved from low and sporadic to severe levels in western coastal area of Taiwan where regrowth ratoon planting is practiced for the second rice crop. This insect occurs usually beneath the leaf sheaths of host plants, and infection causes stunting of rice plants with yellowing, wilting or brittle leaves. In addition, the infected plants either have panicles with unfilled grains or no panicles at all. This rice mealybug has been found also on numerous other gramineae plants, especial Panicum maximun on which the occurrence frequency of this insect is higher than that of other plants. The life cycle of female mealybugs extended to 29.1 ± 2.5 days. Durations for the egg, nympal, resting (prepupal and pupal) and adult stages for male mealybugs were ca. 4-7, 12, 5-6 and 6-8 days, respectively.
