Bemisia emiliae Corbett


Bemisia emiliae Corbett   , a current synonym of Bemisia tabaci   . This grouping of species is characterized by bead-like structures around the body margin that are apparently responsible for the production of fluffy white wax. This species lacks the first abdominal setae, and the first abdominal pore/porette group may or may not be present. Based on molecular mtCO1 data, this species aligns between the tabaci and afer complexes. For molecular mtCO1 tree placement see Gill and Brown (2010, fig. 1.3,

ref. LEP1 and LEP2).

the pore/porette combinations are adjacent and not aligned in any particular arrangement with regard to the body margin. It probably has been isolated as a species for so long that its affinities are only conjecture. complement of submarginal setae that are bristle-like. It seems to have some resemblance to species of Parabemisia Takahashi   ( Fig. 46), but has non-adjacent pore-porette pairs. possibly an environmentally induced morph of B. combreticula   . It shows some tuberculation, the setae are fleshy instead of bristle-like, and many of the setae show a medially directed migration,

particularly PSMS5 (as in B. tabaci   ), and in the thoracic setae (the equivalents of DS3 and DS4).

and an open-ended vasiform orifice with an elongated lingula. However, adult females have an unusual sensorium on the third antennal segment that is not known in Bemisia   . The species is also apparently parthenogenetic. arrangement. Also, CO1 molecular data suggest that it is not particularly closely related to other

Bemisia species.   intermediate between the tabaci group, with adjacent pore-porettes, and the asterobemisia group,

This species was synonymized under Bemisia   by David and Dubey (2009). 49) above, and could be a hairy-leaf morph. This species was synonymized under Bemisia   by David and Dubey (2009). It is nearly identical to B. tabaci   and B. formosana   from smooth leaves, but with a more tapered lingula. The length of the puparium is intermediate between the two. A distinguishing character is the presence of rough C-shaped pores around the margin. These pores are similar to those in the genus Bemisiella Danzig. It   is known only from two puparia. has been included here. Based on the open-ended shape of the vasiform orifice and the setal pair, P.

azaleae   belongs in another genus, possibly Bemisia   , but not in the genus Pealius   (see fig. 53 below.

Its current generic placement is questionable, but is probably conspecific with one of Danzig’s Asterobemisia   or

Neobemisia species.  

of Bemisia   . American and Palaearctic Aleyrodes species.   Its superficial resemblance to Bemisia afer   prompted a study of several Aleyrodes species   morphologically, and a molecular analysis of A. spiraeoides   . On molecular evidence, it is not a Bemisia   (Campbell et al. 1994, 1995) and it differs from B. afer   morphologically by having subequal abdominal segment widths on the middorsum in the puparium, and subequal 4 th and 5 th antennal segments in the adults. Similar to the case of B. tabaci   , the separation of the puparia of the North American A. spiraeoides   and the European Aleyrodes proletella (Linnaeus)  

is not possible. However, the male aedeagus of A. spiraeoides   is slightly curved in lateral view, but the aedeagus of A. proletella   is bent at an almost 90 degree angle at mid-length. as a result of environmental factors, indicating that this phenomenon is not restricted to Bemisia species.  

species. but with long setae. Other species of Eurasian Aleyrodes   , such as A. zygia   and A. philadelphi   discussed above, are short seta forms, as is the European species A. proletella   . These all may be morphs of the same species, since Aleyrodes spiraeoides   shows both kinds of morphs, as indicated in Fig. 57 and 58
