Notes: [Conference held 14 to 16 July, 1993. Original title: Criação de Eurhizococcus brasiliensis (Homoptera: Margarodidae) em tubérculos de batatinha Solanum tuberosum.] 14 Irish potato tubers Solanum tuberosum in the germinating stage were individually infested with 100 first instar nymphs of Eurhizococcus brasiliensis (Homoptera: Margarodidae) in the laboratory. Results indicated that a total of 343 nymphs preferred to colonize the tuber surface, an amount 11 times more than the 31 that colonized the sprouts. This demonstrated that tuber surface was a preferential tissue as compared to the sprouts. The average period of permanence of the nymphs on the host was 40 days, within a range of variation of 33 days minimum and 50 days maximum. Eventually, the host started suffering a rotting process. The above mentioned time lapse of permanence feeding on the host was not enough to complete the nymphal stage and proceed to adulthood. It was therefore concluded that Irish potato tubers are not a suitable substrate to successfully mass rear the insect in the laboratory.
