Diagnostic Notes

The pupal case is yellowish to brownish, sub-elliptical to ovate in shape, sometimes with a narrowed cephalad, 1.3 - 1.5 mm long and 0.8 - 1.0 mm wide, covered by a copious secretion of white wax. On infested leaves, specimens of A. destructor may be completely hidden by wax. The wax rods, emerging from compound pores, are unusually long, attaining in more perfect specimens a length of 12 - 15 mm and are generally broken and intermingled with bands or plates of wax from the marginal tubes. The subdorsum has wax-producing compound pores; one cephalic (smaller than the other ones) and six abdominal pairs. The latter ones are similar in size (up to 90 microns in diameter). Only scattered tiny pores, without a submarginal zone of wide-rimmed pores punctuate the remainder of the dorsal surface. A vasiform orifice is sub-cordate, about as wide as it is long. The operculum is sub-rectangular, about twice as wide as it is long. The lingula is large, tongue-shaped, and extends beyond the posterior margin of the vasiform orifice and bears four setae, two of which are much reduced.
