Borges da Silva, E., Mendel, Z., & Franco, J.C. 2010 Can facultative parthenogenesis occur in biparental mealybug species?. Phytoparasitica 38: 19-21

Notes: The existence of facultative parthenogenesis in mealybugs has been reported by different authors and questioned by others in relation to certain species. We tested the hypothesis of facultative parthenogenesis in relation to three mealybug species, Planococcus citri (Risso), Pseudococcus calceolariae (Maskell) and Pseudococcus viburni (Signoret). The results suggest that these mealybug species are obligate amphimictic.
