TROPHIC INTERACTIONS BETWEEN Eretmocerus eremicus (HYMENOPTERA: APHELINIDAE) AND Trialeurodoes vaporariorum (HEMIPTERA: ALEYRODIDAE) GROWING ON TOMATO AND GREENPEPPER PLANTS

TROPHIC INTERACTIONS BETWEEN Eretmocerus eremicus (HYMENOPTERA: APHELINIDAE) AND Trialeurodoes vaporariorum (HEMIPTERA: ALEYRODIDAE) GROWING ON TOMATO AND GREENPEPPER PLANTS

Understanding multitrophic interactions between parasitoids, pests, and host plants is important for the development of agro-ecological management alternatives that enhance the restoration of ecosystem functions. Laboratory experiments were conducted to determine the influence of tomato (Solanum lycopersicum; cv. Moneymaker) and sweet pepper (Capsicum annuum; cv. Goldenwonder and cv. Yolowonder) on the fitness and parasitisation of the Eretmocerus eremicus attacking Trialeurodes vaporariorum. Parasitoid size, as measured by hind tibia length, was correlated with host pupae size as a fitness indicator. No significant cultivar effect was observed on the longevity of the emerged parasitoids, on the rate of emergence and on immature mortality. However, the host plants did influence development time (days) and sex ratio of the parasitoids. The population growth rate of the parasitoids was observed to be higher than that of T. vaporariorum. T. vaporariorum, feeding on the tomato cv. Moneymaker and the sweet pepper cv. Goldenwonder, was an equally suitable host for Er. eremicus specimens, which makes this parasitoid a promising biocontrol agent in a tomato/sweet pepper mix-cultivation system.

La comprensión de las interacciones multitróficas entre parasitoides, plagas y plantas hospederas es importante para el desarrollo de alternativas de manejo agroecológico que potencien el restablecimiento de funciones ecosistémicas. En este estudio se realizaron experimentos de laboratorio para determinar la influencia del tomate (Solanum esculentum; cv. Moneymaker) y el pimiento dulce (Capsicum annuum; cv. Goldenwonder y Yolowonder) en la aptitud y parasitoidismo del Eretmocerus eremicus atacando a Trialeurodes vaporariorum. El tamaño del parasitoide, medido por la longitud de la tibia posterior, se correlacionó con el tamaño de las pupas del huésped como un indicador de aptitud. No se observó efecto significativo por cultivar en la longevidad de los parasitoides emergidos, en la tasa de emergencia y en la mortalidad de la etapa de inmaduros. Sin embargo, las plantas hospederas influyeron en el tiempo de desarrollo (días) y la proporción de sexos de los parasitoides. La tasa de crecimiento de la población del parasitoide era mayor que la de T. vaporariorum. La mosca blanca de los invernaderos T. vaporariorum se observó alimentándose del tomate cv. Moneymaker y el pimiento dulce cv. Goldenwonder, fue un hospedero igualmente adecuado para especímenes de Er. eremicus, lo que convierte a este parasitoide, en un agente de control biológico con potencial en un sistema de cultivo de tomate/pimiento dulce.
