HYPERPARASITISM IN A JEFFREY PINE (PINUS JEFFREYI) DEFOLIATOR IN THE SIERRA SAN PEDRO MÁRTIR NATIONAL PARK, BAJA CALIFORNIA, MEXICO
Abstract Sawfly larvae of the family Diprionidae are defoliators of conifers, undergoing cyclical outbreaks. Here, we present a tachinid fly, identified as a Chetogena species, which was found parasitizing diprionid larvae from a recent outbreak on Jeffrey pines (Pinus jeffreyi) in Baja California's Sierra San Pedro Mártir National Park. The findings reported here are a new distributional record for Chetogena in Baja California.
期刊介绍:
The Southwestern Naturalist (a publication of the Southwestern Association of Naturalists since 1953) is an international journal (published quarterly) that reports original and significant research in any field of natural history. This journal promotes the study of plants and animals (living and fossil) in the multinational region that includes the southwestern United States, Mexico, and Central America. Appropriate submission of manuscripts may come from studies conducted in the countries of focus or in regions outside this area that report significant findings relating to biota occurring in the southwestern United States, Mexico, and Central America. Publication is in English, and manuscripts may be feature articles or notes. Feature articles communicate results of completed scientific investigations, while notes are reserved for short communications (e.g., behavioral observations, range extensions, and other important findings that do not in themselves constitute a comprehensive study). All manuscripts (feature articles and notes) require an abstract in both English and Spanish.
