| description | The efficiency of an enzymatic detergent (Nudisoit®) in the control of the mobile
scale of the olive tree, Praelongorthezia olivicola (Hemiptera: Ortheziidae), was evaluated under laboratory and on-field conditions. In the laboratory test, four treatments and four repetitions were established in a completely randomized design; individuals surviving after 72 hours was evaluated. In the on-field test, the experimental design was completely randomized with four treatments and three repetitions; the treatments were done 7 days after the application, determining the degree of efficiency. The results indicates a higher control of the mobile scale under laboratory conditions, with an efficiency above 99%, both for nymphs and egg-laying females. On the field test, Nudisoit® exhibited levels of efficiency close to 74% on nymphs and 48% on egg-laying females. Both, the lower control of the plague and the variations observed on field are probably explained by deficiencies in the coverage, where the leaves acted to the detriment of the detergent, which principally acts by contact. |

Se evaluó la eficacia de un detergente enzimático (Nudisoit ®) en el control de la "conchuela blanca móvil del olivo", Praelongorthezia olivicola, en condiciones de laboratorio y campo. En las pruebas de laboratorio, se establecieron cuatro tratamientos y cuatro repeticiones en un diseño completamente aleatorio; se evaluaron individuos sobrevivientes a los tratamientos después de 72 horas. En las pruebas de campo, el diseño experimental fue completamente aleatorio con cuatro tratamientos y tres repeticiones; los tratamientos se evaluaron 7 días después de establecido el ensayo, determinando el grado de eficacia. Los resultados indican un control más alto de la conchuela móvil en condiciones de laboratorio, con una eficacia superior al 99%, tanto para ninfas como para hembras oviponentes. En las pruebas de campo, el detergente enzimático presentó niveles de eficacia cercanos al 74% sobre ninfas y a 48% en hembras oviponentes. Tanto el menor control de la plaga y las variaciones observadas en campo, probablemente se expliquen por deficiencias en el cubrimiento, donde el follaje actuó negativamente sobre el detergente, que actúa principalmente por contacto.
