Abstract
- Se reporta por primera vez a Tromatobia sp. (Hymenoptera: Ichneumonidae) asociada con Neoscona oaxacensis (Araneae: Araneidae), araña que exhibe cuidados maternos prolongados de sus sacos de huevos u ovisacos, en Toluca, Estado de México. El ichneumónido infestó 24% de los ovisacos individuales. No se documentó la presencia de huevos del ichneumónido en los ovisacos infestados. Las larvas de Tromatobia sp. consumieron la totalidad de los huevos de N. oaxacensis y próximas a pupar construyeron cocones individuales, colocándolos uno al lado del otro. Por cada ovisaco individual infestado de N. oaxacensis se encontraron dos a tres pupas y/o adultos de Tromatobia sp. Los adultos abandonaron el interior de los cocones a través de orificios de 2 mm de diámetro. Este estudio representa la primera interacción trófica que ocurre entre Tromatobia sp. y la araña Neoscona oaxacensis en México. Tromatobia sp. (Hymenoptera: Ichneumonidae) is reported for the first time associated with Neoscona oaxacensis (Araneae: Araneidae), a spider that exhibits prolonged maternal care of its egg sacs or ovisacs, in Toluca, State of Mexico. The ichneumonid infested 24% of individual ovisacs. The presence of ichneumonid eggs was not documented in the infested ovisacs. Larvae of Tromatobia sp. consumed all the eggs of N. oaxacensis and, close to pupating, built individual cocoons, placing them side by side. For each individual ovisac infested of N. oaxacensis, two to three pupae and/or adults were counted. Adults left the interior of the cocoons through 2 mm diameter holes. This study represents the first trophic interaction occurring between Tromatobia sp. and N. oaxacensis in Mexico. [ABSTRACT FROM AUTHOR]
