The two-spotted spider mite, Tetranychus urticae Koch, is commonly found on strawberry crops (Fragaria x ananassa). Strawberry plants have defensive mechanisms, which in turn influence the behavior of herbivores. The oviposition and development of the two-spotted spider mite were evaluated on the leaf disks of the cultivars 'Aromas,' 'Camarosa,' 'Camino Real,' 'Diamante,' 'Diamante 10,' 'Diamante 50,' 'Festival,' and 'Seascape.' It was observed that on cultivars such as 'Aromas,' 'Camarosa,' and 'Seascape,' immature survivorship was higher, but no difference was found during the developmental period from egg to adult of T. urticae. The immature development time was also longer on 'Camarosa.' Females laid more eggs on 'Seascape' (8.4 eggs/day), and the least on 'Camarosa' (1.0 egg/day). Mortality was higher at the larval stage and reached more than 50% in three cultivars 'Camarosa,' 'Diamante,' and 'Seascape.' Thus, the cultivars 'Camarosa,' 'Diamante,' and 'Seascape' were the ones that mostly affected the survival, development, and reproduction of T. urticae. |
