Biology of the mite Tetranychus urticae and its control using cinnamon in Rosa spp plants

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