          Abstract

          The aim of this work was to evaluate the predation and behavior activities of the predatory bug Nesidiocoris tenuis Reuter and the lady beetle Cycloneda sanguinea limbifer (Casey) on the aphid. Myzus persicae Zulzer, as well as their effect on this prey dispersal. The experiments were carried out in an acclimatized room at 23.7±1, 8ºC, RH 62,6±5% and 12 h photofase. The number of aphids on the infested and non-infested plants was recorded after 24 hours. Behavioral activities such as moving, searching, resting, encountering aphids, feeding, encountering aphid exuviae, and cleaning, and the time spent in each one were recorded. C. sanguinea limbifer was more voracious than N. tenuis on M. persicae. The ladybeetle led to more aphid dispersion than N. tenuis; however, the highest aphid dispersion occurred when a higher number of both predatory species was used. Significant differences were not observed in the time spent by both predators in moving, encountering and feeding activities, but the time spent in feeding by N. tenuis was longer than that spent by C. sanguinea limbifer. N. tenuis spent longer time in resting activity than C. sanguinea limbifer (p=0,0088). The lady beetle spent longer time searching for the prey than the predatory bug (p=0,0007), but the time needed by C. sanguinea limbifer for cleaning its mouthparts with its front legs was longer than that used by N. tenuis for cleaning its whole body (p=0,0218). The results showed that M. persicae dispersion was an effect of its antipredator behavior in the presence of the predator.

          El objetivo del trabajo fue evaluar las actividades de conducta y depredación de la chinche Nesidiocoris tenuis Reuter y la cotorrita Cycloneda sanguinea limbifer (Casey) sobre el áfido Myzus persicae Zulzer, así como su efecto sobre la dispersión de la presa. Los experiementos se realizaron en una sala climatizada a 23,7±1,8ºC, 62,6±5% de HR y fotoperíodo de 12 horas. El número de áfidos encontrado sobre las plantas sanas e infestadas fue registrado a las 24 horas. Se registró la duración del tiempo dedicado en actividades de conducta como: moverse, buscar, descansar, encuentro con áfidos y exuvias y limpieza. C. sanguinea limbifer fue más voraz que N. tenuis sobre M. persicae. La cotorrita permitió mayor dispersión de áfidos que la chince; sin embargo, la mayor dispersión ocurrió cuando un mayor número de depredadores fue usado en ambas especies. El tiempo dedicado en actividades como moverse, encuentros y aliementación en ambos predadores no mostró diferencias significativas, pero el tiempo dedicado por N. tenuis en alimentarse fue mayor al empleado por C. sanguinea limbifer. N. tenuis gasta más tiempo en descansar que C. sanguinea limbifer (p=0,0088). La cotorrita emplea más tiempo en buscar la presa que la chinche (p=0,0007), pero el tiempo necesitado por C. sanguinea limbifer para limpiar sus piezas bucales con sus patas delanteras fue mayor que el usado por N. tenuis para limpiar todo su cuerpo (p=0,0218). Los resultados mostraron que la dispersión de M. persicae es un efecto de su conducta antipredadora, en presencia de los predadores.
