Notes: Title in English: [Estimation of the fecundity of two scales of fruit trees Aspidiotus nerii Bouche and Pseudaulacaspis pentagona (Targioni-Tozzetti) (Hemiptera: Diaspididae) using a micro-cage technique.] [Estimation of the fecundity of two scales of fruit trees Aspidiotus nerii Bouche and Pseudaulacaspis pentagona (Targioni-Tozzetti) (Hemiptera: Diaspididae) using a micro-cage technique.] Conference proceedings: Actes de la IVème Conférence Internationale Francophone d'Entomologie, Saint-Malo (France, 5-9 juillet 1998).] Aspidiotus nerii Bouche bisexual and parthenogenetic forms, and Pseudaulacaspis pentagona (Targioni Tozzetti) (Hemiptera: Diaspididae) are polyphagous scales with important agronomic impact. Their fecundity was determined under controlled conditions on potato tubers variety "Monalisa" using a micro-cage technique. Irrespective of either the species or the biotype of the scale, the progeny of females were significantly more numerous on the upper side of the tuber than on the lower one. In addition, fecundity of the females was largely dependent on their longevity. There was no significant difference between fecundities of the bisexual and the parthenogenetic forms of A. nerii. The interest of the micro-cage technique in both the laboratory and the field is discussed.
