Milviscutulus mangiferae ( Green, 1889 )


Milviscutulus mangiferae ( Green, 1889) 

( Figs 37View FIGURE 37, 38View FIGURE 38)

Lecanium mangiferae Green, 1889: 249  Diagnosis. Dorsum with anal plates pyriform, each with 4 apical setae ( Figs 37DView FIGURE 37, 38EView FIGURE 38); dorsal setae clavate ( Fig. 38FView FIGURE 38); duct tubercles present ( Fig. 38DView FIGURE 38). Marginal setae spinose, mostly with fimbriate apices ( Fig. 38MView FIGURE 38). Venter with multilocular disc-pores usually each with 7–10 loculi, present on posterior area of abdomen, occasionally with a few laterad of metacoxa ( Fig. 38KView FIGURE 38); antenna 8 segmented ( Fig. 38PView FIGURE 38) (partially adopted from Williams & Watson 1990; Hodgson 1994).

Material examined. 3 ♀♀, LAOS, Phou Khao Khuay National Bio-Diversity Conservation Area, Thaphabath Dist., Bolikhamsai Prov., 4.v.2015, coll. J.Y. Choi, on Mangifera indica  L. ( Anacardiaceae  ); 1 ♀, Vangvieng Dist., Vientiane Prov., 8.ii.2017, coll. P.P. Soysouvanh, on Chrysalidocarpus lutescens H. Wendl.  ( Arecaceae  ).

Hosts. Polyphagous. According to García Morales et al. (2016), M. mangiferae  has been recorded from plants belonging to 82 genera in 42 families. In Laos, it has been found on Dracaena  sp. ( Asparagaceae  ) and Ficus  sp. ( Moraceae  ) ( Suh & Bombay 2015).

Distribution. All zoogeographical regions; Oriental Region ( India, Indonesia, Laos, Malaysia, Philippines, Singapore, Sri Lanka, Taiwan, Thailand and Vietnam) ( Suh & Bombay 2015; García Morales et al. 2016).

Economic importance. Milviscutulus mangiferae  was listed as a major pest of mango ( Mangifera indica  ) in Israel, U.S.A. and the Pacific region ( Gill & Kosztarab 1997), causing yellowing, leaf drop, and death of branches ( Grimshaw & Donaldson 2007).

Remarks. Milviscutulus mangiferae  is closely related to M. spiculatus Williams & Watson, 1990  , but is easily differentiated by having clavate or capitate dorsal setae and mostly fimbriate marginal setae; in contrast, M. spiculatus  has flagellate to lanceolate but never bluntly clavate or capitate dorsal setae, and the marginal setae are mostly pointed. For comparisons with other species of Milviscutulus  , see Williams & Watson (1990).
