          Abstract

          En el trópico se dispone de pocos datos de la mayoría de los organismos, incluyendo las mariposas, en aspectos claves de su ciclo de vida, sus plantas hospederas y factores explicativos de su diversidad y abundancia. El objetivo de este trabajo fue identificar las plantas hospederas de larvas Ithomiini (Lepidoptera) en agroecosistemas de café y evaluar el efecto de las variables: sistema de producción, área en bosque y diversidad de hospederas sobre la diversidad y abundancia de este grupo. En seis fincas de café de Fredonia (Antioquia), Colombia, se recolectaron plantas de las familias Apocynaceae, Gesneriaceae y Solanaceae, que fueron identificadas en los Herbarios HUA y MEDEL de Medellín. En las fincas se registraron los adultos observados en vuelo y se recolectaron huevos, larvas y pupas de Ithomiini de sus plantas hospederas para su cría en laboratorio, hasta la emergencia de adultos. Se determinó el porcentaje de sobrevivencia y mortalidad debida a parasitoidismo. Los datos de diversidad se analizaron por medio de un Análisis de Regresión de Poisson. En los agroecosistemas de café se registraron 27 especies vegetales y 27 mariposas adultas Ithomiini, en laboratorio, se criaron 326 individuos de ocho especies, recolectados sobre siete plantas de la familia Solanaceae. Dos plantas constituyen registros nuevos como hospederas de las especies de Lepidoptera: Solanum atropurpureum hospedera de Mechanitis menapis y Solanum deflexiflorum hospedera de Pteronymia picta y P. latilla. La diversidad de Ithomiini fue explicada por la diversidad de hospederas y por el sistema de sombrío.

          In the tropics, few data are available for most organisms, included butterflies, on key aspects of their life cycles, host plants, and explanatory factors of its diversity and abundance. The objective of this study was to identify the larval host plants of Ithomiini (Lepidoptera) larvae in coffee agroecosystems and to evaluate the effect of the following variables: production system, forested area, and host plant diversity on the diversity and abundance of this group. In six coffee farms from Fredonia (Antioquia), Colombia, plants from the families Apocynaceae, Gesneriaceae, and Solanaceae were collected and identified in HUA and MEDEL Herbariums in Medellin. In the farms, adults observed in flight were recorded and Ithomiini eggs, larvae and pupa were collected from host plants and reared in the laboratory until adulthood. Percent survival and mortality due to parasitism were quantified. Diversity data were analyzed by means of a Poisson Regression Analysis. In this coffee ecosystem, 27 plant species and adults from 27 butterfly species were observed, while in the laboratory 326 individuals of eight species were reared after their collection from seven Solanaceous plant species. Two host plants are new records for Lepidoptera species: Solanum atropurpureum as host for Mechanitis menapis and S. deflexiflorum as host for both Pteronymia picta and P. latilla. Ithomiini diversity was explained by host plant diversity and use of the shaded coffee system.
