Remarks
- Systematics: Pseudococcus importatus is very similar to P. sociabilis in having small size discoidal pores near eyes, no rim around eye, translucent pores restricted to hind tibia, and several oral collars near cerarii 12, 11, and 10. Pseudococcus importatus differs by having: Longest dorsal body setae 22(17-25)1l long; anal-ring setae 132(111-145)1l long; longest ventral body setae 68(44-98)1l long; longest interantennal setae 96(70-130)1l long; hind tarsus 102(95-110)µ long;13(1-23) dorsal oral rims on abdomen. Pseudococcus sociabilis has: Longest dorsal body seta 11(l0-15)µ long; anal-ring seta 174(146-190)µ long; longest ventral body seta 100(73-110)µ long; longest interantennal seta 30(98-166)µ long; hind tarsus 122(117-134)µ long; 22(18-25) dorsal oral rims on abdomen. (Gimpel & Miller, 1996)
- Structure: Translucent pores restricted to hind tibiae; 13(1-23) dorsal oral-rim tubular ducts on abdomen; 1(0-3) oral rims on ventral submargin from segment II to cerarius 13; 10(4-21) oral-collar tubular ducts in cluster mesad of cerarius 12; 1(0-3) oral-collars posterior of eye; circulus 97(75-126)µ wide, usually divided by intersegmental line. (Gimpel & Miller, 1996)
- Biology: Occurring exposed on the leaves of its host plants. Allavailable records of this species have been taken from orchids.
- Economic Importance: Johnson (1964) reported this mealybug as an orchid pest in California.
