SECONDARY METABOLITE RELATIONSHIP OF SEVEN ROSE (ROSA SP.) CULTIVARS WITH THE POPULATION DYNAMICS OF TETRANYCHUS URTICAE KOCH (TROMBIDIFORMES: TETRANYCHIDAE)
Two-month cumulative populations of Tetranychus urticae Koch in greenhouse rose (Rosa sp.) cultivars showed the following incidence (from lower to higher): Latin® ¬ Polar Star® < Peokubo® ¬ Leonidas® < Royal Bacara® < Haylander® < Ben Hur®. However, when populations were calculated as mi...

| Sumario: | Two-month cumulative populations of Tetranychus urticae Koch in greenhouse rose (Rosa sp.) cultivars showed the following incidence (from lower to higher): Latin® ¬ Polar Star® < Peokubo® ¬ Leonidas® < Royal Bacara® < Haylander® < Ben Hur®. However, when populations were calculated as mite/day/leaf (A/D/H) we found the following sequence: Latin® ¬ Peokubo® < Polar Star® ¬ Leonidas® < Royal Bacara® < Haylander® < Ben Hur®. In addition, we did not find correlation between secondary metabolites of tepenes and tannins. However, Latin® and Peokubo® cultivars showed a negative correlation with terpenes and tannins. This suggest that Ben Hur®, Haylander®, Royal Bacara®, Leonidas® and Polar Star® cultivars allow broadly the development of T. urticae, meanwhile Latin® and Peokubo® cultivars were more tolerant to T. urticae because of the presence of terpenes and tannins. On the other hand, Abamectin is the active ingredient most commonly applied in rose cultivars at a rate of 500 ml per hectare at US$120.00 per application with two applications biweekly. Thus, the resistant varieties resulted in savings of US$240.00 and low establishment of T. urticae. Moreover, it keeps rose quality suitable for local and national markets. |
