Abstract

Orellana A, Erazo M. 2002. Possible population decline of the swallowtail Papilio polyxenes check for this species in other resources americus Kollar (Lepidoptera: Papilionidae) in the intra-Andean valley of Mérida, Venezuela. Entomotropica 17(2):189-190.

Since the second half of the 90's, the swallowtail butterfly, Papilio polyxenes americus Kollar, 1859, a formerly common species, has become scarce or may even be disappearing from the Chama river basin of Andean Mérida, Venezuela. No concrete explanations are given for the fact, but it is presumed that it may be linked to human activities, especially the use of pesticides.

Keywords

Resumen

Orellana A, Erazo M. 2002. Posible declinación poblacional de la mariposa Papilio polyxenes check for this species in other resources americus Kollar (Lepidoptera: Papilionidae) en el valle intra-andino de Mérida, Venezuela. Entomotropica 17(2):189-190.

A partir de la segunda mitad de los años 1990 Papilio polyxenes americus Kollar, 1850, anteriormente común, parece estar desapareciendo de la zona media del río Chama, en el estado andino de Mérida, Venezuela. Esto se sustenta en observaciones no sistemáticas, pero continuas. No se ofrecen explicaciones concretas para esta disminución, pero pudiera estar vinculada a actividades humanas, especialmente el uso de plaguicidas.

Palabras-clave
