Abstract
El objetivo de este trabajo fue determinar el impacto de la aplicación de aceites esenciales y metabolitos microbiológicos (Xilotrom) sobre huevos y larvas de Chrysoperla carnea. Los tratamientos evaluados fueron T0 (Testigo absoluto) T1 (Testigo agua) y T2 (aceites esenciales y metabolitos microbiológicos 1.5 cc/l), T3 (aceites esenciales y metabolitos microbiológicos 2.5 cc/l), y T4 (aceites esenciales y metabolitos microbiológicos 5 cc/l),
los que fueron distribuidos utilizando un diseño completamente al azar (DCA) y se consideraron 5 tratamientos y 5 repeticiones. La unidad experimental estuvo constituida por una caja plástica en la cual se acondicionó hojas de alcachofa sobre la que se colocó láminas de papel kraft con 10 huevos de C. carnea. De igual manera se procedió en el bioensayo con larvas de C carnea del segundo estadio de desarrollo, las que fueron colocadas directamente en las hojas. Para la aplicación de los tratamientos se utilizó un asperjador manual. Los parámetros evaluados fueron porcentaje de viabilidad de los huevos y porcentaje de mortalidad de larvas por tratamiento. Los resultados mostraron que la aplicación de las dosis de aceites esenciales y metabolitos microbiológicos evaluadas no afectaron la viabilidad de los huevos. El tratamiento T3 (Aceites esenciales y metabolitos microbiológicos) en dosis de 2.5 cc/l causó con el mayor porcentaje de mortalidad de larvas de C. carnea con 31.88 %.
ABSTRACT The objective of this work was to determine the impact of the application of essential oils and microbiological metabolites (Xilotrom) on eggs and larvae of Chrysoperla carnea. The treatments evaluated were T0 (Absolute control), T1 (Water control) and T3 (essential oils and microbiological metabolites 1.5 cc/l), T4 (essential oils and microbiological metabolites 2.5 cc/l), and T5 (essential oils and microbiological metabolites 5 cc/l), which were distributed using a completely randomized design (DCA) and 5 treatments and 5 repetitions were considered. The experimental unit consisted of a plastic box in which artichoke leaves were placed, on which sheets of kraft paper with 10 C. carnea eggs were placed. The bioassay was carried out in the same way with C. carnea larvae of the second stage of development, which were placed directly on the leaves. A manual sprayer was used to apply the treatments. The parameters evaluated were percentage of egg viability and percentage of larval mortality per treatment. The results showed that the application of the doses of essential oils and microbiological metabolites evaluated did not affect the viability of the eggs. Treatment T3 (Essential oils and microbiological metabolites) at a dose of 2.5 cc/l caused the highest percentage of mortality of C. carnea larvae with 31.88%.
