Dysmicoccus lepelleyi (Betrem)

Family

Pseudococcidae

Field characters

Field characters not recorded. Based on characteristics of slide-mounted adult female, with body broadly oval; body covered by white mealy secretion; ovisac ventral only or absent entirely, absent from dorsum; 17 pairs of thin wax filaments around perimeter of body. Present on fruit, stems, and leaves of host.

Validation characters

Dorsal margin of body with several large oral-collar tubular ducts; cerarii, excluding anal lobe pair, usually with 3 or more conical setae; dorsal abdominal segments VII and VIII usually with setae conspicuously longer than other dorsal setae; translucent pores on hind coxa, femur, and tibia, rarely also present on trochanter; ventral multiloculars usually restricted to posterior 3 segments, rarely on segments V and VI also.

Comparison

Dysmicoccus lepelleyi is similar to D. brevipes by usually having dorsal setae on segments VII and VIII that are much longer than on other segments and ventral multilocular pores usually confined to last 3 abdominal segments. Dysmicoccus lepelleyi differs by lacking discoidal pores near the eye and by having translucent pores on the hind coxa. Most other characters are quite variable.

This species was intercepted 81 times at U. S. ports-of-entry between 1995 and 2012, with specimens originating from Cambodia, China, Hong Kong, Indonesia, Malaysia, The Philippines, Singapore, Taiwan, Thailand and Vietnam. We also have examined specimens taken in quarantine from Cambodia (Garcinia, Nephelium); France (Garcinia); Indonesia (Garcinia, Musa, Nephelium); Korea (Garcinia); Malaysia (Dracaena); The Philippines (Cocos, Garcinia, Lansium, Psidium); Singapore (Ananas, Garcinia); Taiwan (Garcinia); Thailand (Citrus,Garcinia, Lansium, Litchi, Nepheliumm Psidium); Vietnam (Annona, Garcinia, Litchi, Nephelium). It is commonly taken on a diversity of tropical fruit hosts such as Annona, Artocarpus, Citrus, Garcinia, Mangifera and Psidium. ScaleNet lists the species from more than 15 families of host plants. It is known only from the Oriental zoogeographic region.
