Pulvinaria polygonata Cockerell, 1905


Pulvinaria polygonata Cockerell, 1905 

( Figs 41View FIGURE 41, 42View FIGURE 42)

Pulvinaria polygonata Cockerell 1905: 131  .

Diagnosis. Dorsal derm with polygonal reticulations; tubular ducts present, but small ( Fig. 42EView FIGURE 42); duct tubercles present ( Fig. 42DView FIGURE 42). Marginal setae bluntly spinose, mostly with fimbriate apices ( Fig. 42AView FIGURE 42). Stigmatic clefts distinct, each containing 4 or 5 stigmatic spines ( Figs 41CView FIGURE 41, 42CView FIGURE 42). Venter with multilocular disc-pores usually each with 8 loculi, abundant around vulvar area, a few pores also present laterad of meta- and mesocoxa ( Fig. 42IView FIGURE 42); tubular ducts of 3 types: type I each with a broad inner ductule, present on medial area of head, thorax and anterior abdomen; type II each with a narrow inner ductule, present on medial and inner submarginal area of head, thorax and abdomen; and type III each with a filamentous inner ductule, present in submarginal areas ( Figs 41DView FIGURE 41, 42JView FIGURE 42); antenna 8 segmented (partially adopted from Williams & Watson, 1990).

Material examined. 10 ♀♀, LAOS, Kham Dist. , Xiangkhoang Prov., 2.v.2015, coll. J.Y. Choi, on Citrus sp. ( Rutaceae  ). 

Hosts. Polyphagous. According to García Morales et al. (2016), P. polygonata  has been recorded from plants belonging to 10 genera in 7 families. In Laos, it has been found on Ficus  sp. ( Moraceae  ) ( Suh & Bombay 2015).

Distribution. Mainly known from Australian, Oriental ( Bangladesh, India, Laos, Philippines, Sri Lanka, Taiwan and Vietnam) and Palearctic Regions ( Suh & Bombay 2015; García Morales et al. 2016).

Economic importance. Mani & Krishnamoorthy (1998) considered P. polygonata  to be a serious pest of mango ( Mangifera indica  ) in India. In addition, Williams & Watson (1990) noted that P. polygonata  could be a potential pest of citrus because of its host preferences. The species is frequently intercepted at U.S. ports ( Miller & Miller 2003).

Remarks. Pulvinaria polygonata  closely resembles P. aurantii Cockerell  , but is easily separated by the number of stigmatic spines in each spiracular cleft: P. polygonata  has 4–5, whereas P. aurantii  has only 3 ( Takahashi 1955b).
