Remarks
- Biology: This species is usually found on grasses, but frequently the adult females move onto adjacent trees to oviposit.
- Economic Importance: Although this species does not appear to cause any damage, its presence under the calyxes of apples and pears grown for export has caused concern in Australia and New Zealand (Ward, 1966). Pheromone lures are highly sensitive and selective, easy to use, and stable for extended periods under field conditions. There have been anecdotal reports of possible cross-attraction of rye grass mealybug, Phencoccus graminicola, to vine mealybug pheromone, but these have not been confirmed. (Zou, et al., 2013)
- General Remarks: Description and illustration of adult female by McKenzie (1967), Williams (1985), Cox (1987) and by Granara & Szumik (2007).
