“…In that study, some spiderlings might emerge because the number of larvae was low (Fitton et al, 1988;Schwarz and Shaw, 1999). On the other hand, other records show that the egg consumption could be complete, for example, Camera lunavenatrix Santos & Onody, 2016 (Ichneumonidae: Cryptinae) consumed 100% of the eggs of the spider Selenops cocheleti Simon, 1880 (Selenopidae) (Villanueva-Bonilla et al, 2016). The genera Tromatobia (Ichneumonidae: Pimplinae) and Aprostocetus (Chalcidoidea: Eulophidae) also consume 100% of the eggs when they attack the eggs-sac of the spider Araneus omnicolor Keyserling, 1893 (Araneidae) (Sobczak et al, 2012(Sobczak et al, , 2015.…”

First record of the parasitoid wasp Lymeon sp. (Ichneumonidae: Cryptinae) associated with spider eggs-sac of Araneus vincibilis (Araneae: Araneidae) in Northeastern Brazil

Abstract Lymeon Förster, 1869 is a very large genus of the Cryptinae (Ichneumonidae) with predominantly Neotropical distribution where females attack small cocoons of various groups of insects and spider eggs-sac. In the present study, we report the first record the interaction between the parasitoid wasp Lymeon sp. (Ichneumonidae), with eggs-sac of spider Araneus vincibilis (Araneidae) in Northeastern Brazil. We observed that although the female of A. vincibilis cares for the eggs that were attacked by Lymeon sp, the wasp larva consumed about 80% of spider eggs, indicating that both maternal care and the physical barrier offered by the eggs-sac may not provide absolute defense against predators.

“…Barrantes et al (2014) recorded pupae of an unknown egg predator within the egg sac of Deinopis sp. In other species of spiders, predation of up to 100% of eggs by wasps of the subfamily Cryptinae (Ichneumonidae), regardless of maternal care (Villanueva-Bonilla et al 2016;Sobczak et al 2020), is commonly reported.…”

“…Las especies del subgénero Mehria pueden representar una importante fuente de mortalidad para los sacos de huevos que atacan (Hieber et al, 2002), información que apoya los datos de esta investigación (tabla 1). La familia Ichneumonidae tiene varios géneros asociados a ovisacos de arañas principalmente en las subfamilias Pimplinae y Cryptinae (Austin, 1985;Fitton et al, 1987;Sobczak et al, 2012;Villanueva-Bonilla et al, 2016 (Kasparyan, 2017;Hymenoptera Online, 2019). Atacan capullos de insectos y ovisacos de arañas (Townes, 1970).…”

Insectos asociados a ovisacos de Argiope argentata (Fabricius, 1775) (Arachnida: Araneae) en Panamá

Las arañas son ovíparas, colocan sus huevos de forma agrupada cubiertos por una o varias capas de hilos de seda que forman un ovisaco. La cantidad de huevos dentro de estos ovisacos dependen de la especie de araña y secundariamente de la alimentación de la madre. Los ovisacos protegen los huevos de condiciones ambientales adversas y del ataque de hongos, sin embargo, resultan inefectivos contra algunos insectos. Argiope argentata es una especie de Araneidae que se distribuye desde Estados Unidos hasta Chile y Argentina, es relativamente grande y fácilmente reconocible por su coloración, genitalia y forma característica del abdomen. A pesar de ser una especie de amplia distribución, no hay información sobre los insectos que se alimentan de sus huevos. Se describen las interacciones ecológicas de depredación y parasitismo entre insectos y ovisacos de la araña Argiope argentata (Araneae: Araneidae) recolectados en tres localidades de Panamá. Por primera vez se reportan en huevos de A. argentata a la avispa endoparasitoide Baeus sp. (Hymenoptera: Platygastridae), los depredadores Sarcophaga (Mehria) silbergliedi (Diptera: Sarcophagidae) y dos especies de Cryptinae (Hymenoptera: Ichneumonidae), una de las cuales pertenece al género Lymeon sp. Adicionalmente, se reportan tres especies del género Conura (Hymenoptera: Chalcididae): C. nigrifrons, C. amoena y C. abdominalis como parasitoides de pupas de Cryptinae (Ichneumonidae).
