Are Phenacoccus solani Ferris and P. defectus Ferris (Hemiptera: Pseudococcidae) distinct species? Chatzidimitriou, Evangelia Simonato, Mauro Watson, Gillian W.

Lloyd (1952) showed that P. s o l a niis a parthenogenetic, thelyotokous species, (confirmed by Ben-Dov 2005) and McKenzie (1967) said it is viviparous; however, at that time workers did not distinguish between viviparity and ovoviviparity. True viviparity is rare in insects so we consider  P. solanito be ovoviviparous. No males have been recorded for  P. solaniso it is likely that it reproduces parthenognetically.
