Facultative egg-larval parasitism of the beet armyworm, Spodoptera exigua (Lepidoptera: Noctuidae) by Cotesia marginiventris (Hymenoptera:Braconidae)
The braconid parasitoid Cotesia marginiventris (Cresson) has long been known to be a larval parasitoid of numerous lepidopteran species. Recent field observations, however, indicated that C. marginiventris is also capable of functioning as an egg-larval parasitoid of the beet armyworm, Spodoptera ex...

description | The braconid parasitoid Cotesia marginiventris (Cresson) has long been known to be a larval parasitoid of numerous lepidopteran species. Recent field observations, however, indicated that C. marginiventris is also capable of functioning as an egg-larval parasitoid of the beet armyworm, Spodoptera exigua (Hübner). These field observations were corroborated by laboratory observations, demonstrating that C. marginiventris is capable of ovipositing in S. exigua eggs, and of successfully developing and emerging from host larvae hatching from stung eggs. The mechanisms used by the parasitoids to locate host egg masses in the field were not determined. These results lend support to phylogenetic hypotheses of the Braconidae that indicate a close relationship between the Cheloninae and the microgastroid taxa. /// Desde hace tiempo se conoce que el bracónido Cotesia marginiventris (Cresson) es un parasitoide de numerosas especies de lepidópteros. Sin embargo, observaciones recientes de campo indicaron que C. marginiventris es además capaz de funcionar como un parasitoide huevo-larval del gusano de la remolacha, Spodoptera exigua (Hübner). Tales observaciones de campo fueron corroboradas en el laboratorio, demostrando que C. marginiventris es capaz de ovopositar en huevos de S. exigua y emerger exitosamente de las larvas del hospedero eclosionadas de huevos parasitados. Los mecanismos usados por los parasitoides para localizar las masas de huevos del hospedante en el campo no fueron determinados. Estos resultados soportan la hipótesis filogenética de que en los Braconidae hay una estrecha relación entre los Cheloninae y los taxa microgastroides. |
