The behavior of sunflower cultivars was evaluated in relation to the attack of Chlosyne lacinia saundersii, under field conditions. The following parameters were evaluated: number of larvae per plant, number of larvae per linear meter of plants, percentage of attacked plants and percentage of defoliation. The results were as follows: the most suitable methods for evaluating the insect infestation were the percentage of attacked plants and the number of larvae per linear meter of plants; the less infested sunflower cultivare were 'Cargill-33', 'Contissol', 'Issanka-F', 'PIGB', 'Uruguai' and 'Contissol-621', while 'Contissol-711', 'Contissol-112', and 'Ruinano-P/ were the most infested ones. The occurrence of C. lacinia saundersii was higher ...
