Biología del ácaro Tetranychus urticae y su control utilizando canela, en plantas de Rosa spp

The effectiveness under laboratory conditions of Cinnamon (Cinnamomum verum) on the Tetranychus urticaemite was evaluated. This species is great economic importance because it affects all types crops such as vegetables, fruit trees, and ornamentals. damage consists removal cellular content, leaving cell practically empty. T. urticaehas presented resistance problems to various chemicals, which why alternatives have been sought reduce its population in crops. One them, use botanical products, for this, an investigation carried out conditions, evaluating effect cinnamon different presentations against mite. treatments were made up of: T1 water (5 mL), T2 based powder (1 g) T3 infusion mL) T4 Abamectin (Vertimec®) 0.6 mL; T5 ethanolic extract mL at 5%) T6 control without application. A mortality females eggs registered after 24 hours 11.66 ±11.69; 6.66 ± 2.58; infused 60.00 ±14.1; 36.66 14.024; 38.33 ±16.02; 7.50 6.89; 20.00± 14.14; 0.00 0.00; 46,667 20.65; 5.00 3.16. obtained 0% both eggs. For biological cycle test, total development time mite 11.01 0.69, presenting egg state 5.11 0.60; larval stage 2.18 0.46; protonymph 1.96 0.44 deutonymph 1.75 0.43. treatment that highest percentage one represented by infusion. These findings are a very important tool maintain urticaeinfestation thresholds.
