Resumen
[ES] La resistencia comportamental puede definirse como el conjunto de modificaciones conductuales inducidas en aquellos
individuos afectados por plaguicidas. Los objetivos de este trabajo son: evaluar el efecto que los diferentes tipos de manejo
kle cultivo sobre la abundancia de los enemigos naturales, determinar el comportamiento de los enemigos naturales
klurante los tratamientos mayoritarios de plaguicidas, estudiar la resistencia comportamental inducida por la aplicación de
insecticida. En la provincia de Jaén se seleccionaron 3 tipos de olivar (Convencional, Control Integrado de Plagas y
Ecológico). Para el tratamiento de Prays o/eae, en cada tipo de olivar se establecieron una parcela control y una parcela
~ratada con insecticida, ambas de 5 x 5 olivos. Para el tratamiento contra Bactrocera o/eae solo se trabajó con el olivar
K:onvencional, delimitando parcelas de 7 x 7 olivos. Los resultados de este studio afirman que los manejos basados en la
~plicación de insecticidas provocan una disminución en la abundancia de enemigos naturales, además de inducir resistencia
K:;omportamental en determinadas especies.
[EN] rrhe behavioral resistance can be defined as the set of behavioral modifications induced in those individuals affected by pesticides. The objectives of this work are: evaluate the effect of different types of crop management on the abundance of natural enemies, determine the behavior of natural enemies during the majority of pesticide treatments, study the behavioral resistance induced by the application of insecticide. In Jaén 3 types of olive graves were selected (Conventional, lntegrated Pest Management and Ecological). For the treatment of Prays oleae, in each type of olive grove a control plot ~nd a plot treated with insecticide were established, both of 5 x 5 olive trees. For the treatment against Bactrocera o/eae, k)nly the conventional olive grave was worked on, delimiting parcels of 7 x 7 olive trees. The results of this study affirm that the management based on the application of insecticides cause a decrease in the abundance of natural enemies, as well as inducing behavioral resistance in certain species.
