Zacchi, L., & Vaughan Martini, A. 2003 Distribution of three yeast and yeast-like species within a population of soft scale insects (Saissetia oleae) as a function of developmental age.. Annals of Microbiology 53(1): 43-46.

Notes: The distribution of Aureobasidium pullulans, Rhodotorula sp. and Sporobolomyces roseus within a population of soft scale insects (Saissetia oleae) varied significantly as a function of developmental age. Younger individuals (nymphs of age I) generally hosted a significantly higher number of cells of A. pullulans and Sporobolomyces roseus compared to older nymphs (II and III age) or adults. This observation may be consistent with the hypothetical role of microbial endosymbionts in favouring host growth, development and/or detoxification.
