The present invention relates to a trapping device for Drosophila Spp, preferably D. Suzukii consisting of a red-shaped vessel-shaped base and containing between 15 and 40 perimeter entrances uniformly distributed in the upper half of the vessel. Also, it possesses a transparent lid with a hemispherical shape forming an area of ??internal capture of greater volume which favors the retention and the final capture of flies. Additionally, this lid has a top opening that allows the inclusion of an extra device primed with a supplementary attractant, preferably a fermentation one not miscible with the attractant used in the base of the trap, thus improving the capture levels and the effectiveness of the system. Said additional inner device also favors the flies disorientation and favors its capture if necessary it can be replaced by a new one without dismantling the trap. The combination of the two immiscible attractants arises a mixture of volatiles based on microbial fermentation and on the emission of acetic acid (vinegar odor) and ethanol highly attractive for the pest and obtaining highly effective and lasting attractant. Said device is supplied with a specific coupling structure to the area of ??the holes allow emptying it easily and without losing liquid or part of the captured flies, thereby favoring its use in monitoring tasks.Esta invención hace referencia a un dispositivo de trampeo para Drosophila spp, preferentemente D. suzukii, que consiste en una base con forma de vaso de color roja y que contiene entre 15 y 40 entradas perimetrales uniformemente distribuidas en la mitad superior del vaso. Dispone de una tapa transparente con forma semiesférica, que conforma un área de captura interior de mayor volumen lo que favorece la retención y la captura final de moscas. De manera adicional, esta tapa tiene una abertura superior que permite la inclusión de un dispositivo adicional que puede ser cebado con un atrayente suplementario, preferiblemente un atrayente de fe
