Remarks

• Systematics: Slide-mounted adult female with: enlarged setae nearly straight-sided, apices blunt or rounded, marginal setae conspicuously longer than other setae on abdomen; multilocular pores surrounding vulva predominantly with 7 or more loculi; largest dorsal sublateral or medial enlarged setae on posterior 3 abdominal segments more than 2.5 times longer than dorsal lateral enlarged setae (Miller & Miller, 1993).
• Structure: Adult female yellow; turning white prior to ovisac formation. Body lined with long crystalline rods. Ovisac is elongate, white and may contain 21-124 yellow eggs (Fuzy, 1969).
• Biology: This species has two generations per year with eggs in the ovisac serving as the overwintering stage. First generation crawlers appear in April and second generation crawlers appear in late June or July. Adult females of the second generation complete egg laying in late September or early October. Males are common (Fuzy, 1969)(Miller & Miller, 1993).
• Economic Importance: This species can be very destructive to the host if left unchecked for several years (Miller & Miller, 1993).
• General Remarks: Detailed description and illustration by Williams (1969) and by Miller & Miller (1993).
