Dos especies de cinípidos introducidas en Chile, inductoras de agallas en malezas herbáceas (Hym., Cynipidae)

Abstract

[ES] Se cita por primera vez en Chile y en el continente americano la especie europea Timaspis cichorii (Hymenoptera Cynipidae), inductora de agallas crípticas en los tallos de Cichorium intybus (Asteraceae), una planta originaria de la región mediterránea. Phanacis hypochoeridis, otro cinípido introducido desde Europa, que forma agallas conspicuas en los tallos de Hypochoeris glabra (Asteraceae), se cita por segunda vez en Chile. Ambas especies se recolectaron en las inmediaciones de la Reserva Nacional Los Queules, una de los pocos remanentes de bosque Maulino, dentro de un programa de muestreo e inventario de Hymenoptera efectuado con trampas Malaise. Este trabajo confirma el incremento de casos conocidos de introducción de especies europeas de cinípidos en Sudamérica en años recientes. Ambas especies se encontraron en las áreas perturbadas que rodean la Reserva Nacional Los Queules, pero no en el interior de la Reserva como en otros casos conocidos, sugiriendo que el bosque Maulino sería aún bastante resistente a invasiones biológicas.

[EN] The European species Timaspis cichorii (Hymenoptera Cynipidae),inducing cryptic galls in stems of Cichorium intybus (Asteraceae),a plant native to the Mediterranean region, is recorded in Chile and on the American continent for the first time. Phanacis hypochoeridis, another cynipid introduced from Europe, that forms noticeable galls in the stems of Hypochoeris glabra (Asteraceae) is cited in Chile a second time. Both species were collected in the surroundings of Reserva Nacional Los Queules, one of the few remains of Maulino forest, within a program of sampling and inventory of Hymenoptera, carried out with Malaise traps. This study confirms the increase of known cases of introduction of European cynipid species to South America in recent years. Both species were found in the disturbed areas surrounding the Reserva Nacional Los Queules, but not inside the Reserva, like in other well-known cases, suggesting that Maulino forest would still be resistant enough to biological invasions.
