Remarks

• Structure: Live females are characterized by a dark purple body, covered with a thin layer of powdery white wax and with 2 pairs of caudal filaments, of which the posterior pair is longer and broader than the anterior. They have a large ovisac containing pink eggs that covers the entire body. The morphological features of fixed slide-mounted females consist of an elongated body with almost parallel-sides.Dorsum with cerarii located on the last 2 abdominal segments; anal lobe cerarius with 2 quite large, conical setae, 5-10 slender auxiliary setae and 20-30 trilocular pores; preanal cerarius with 2 conical setae and 1-3 slender auxiliary setae and 3-10 trilocular pores. Anal ring apical with 6 setae. Multilocular disc pores absent. Trilocular pores evenly distributed over the entire dorsum. Scattered simple circular pores. Oral rim tubular ducts arranged in 3 or 6 transverse rows across each abdominal urite, except for segment IX. Smaller oral collar tubular ducts arranged sparsely in rows across abdominal urites; larger oral collar ducts moderately numerous to numerous on abdominal urites IV- VIII, moderately numerous on the margins of most other segments. Body setae moderately long and slender. Venter with 8-segmented antennae. Well developed legs, without denticles on tarsal claws; hind femora and tibiae with translucent pores. Absent circulus. Multilocular disc pores present in midregion of abdomen and around vulva, arranged in rows across postmedian edges of abdominal urites IV-VII and antero-median edge of VII, and scattered over median areas of thorax. Widely distributed trilocular pores. Scattered simple circular pores. Oral rim tubular ducts present in limited numbers along lateral areas of most abdominal urites, and in clusters on the thorax. Smaller oral collar tubular ducts in rows across median areas of abdominal urites II-VII, and a few on median areas of thorax. The larger oral collar ducts numerous on median areas of abdominal urites V- VII, and in large marginal groups on most body segments. Small and slender body setae. (Longo, 2012)
• Biology: James (1937a) showed that reproduction is sexual (in laboratory population in England) and evaluated its sex ratio. Living on the bulbs of the host plant.
• Economic Importance: In the more temperate regions of the world, this mealybug often causes concern in greenhouses on plants of the families Liliaceae, Iridaceae and Agavaceae. The propagation of African lilies by seeds is strongly encouraged because seeds are not infested by the mealybug. (Longo, 2012)
