Twenty pricky-pear varieties were evaluated as a completely randomized experimental design with four replicates. The plants were artificially infested. The infestation level was evaluated by a 0 - 5 scale. The most resistants clone are "Miúda" and "Orelha de Elefante".© 2009 Sociedade Brasileira de Zootecnia.
