Resumen:
Se colectaron 1,300 larvas de Spodoptera frugiperda de los tres primeros estadios en maíces, en una parcela experimental en Nayarit en 2011 y 2012. Las larvas fueron examinadas en busca de enemigos naturales. Se obtuvieron e identificaron seis especies de parasitoides: Cotesia sp. (0.3%) y Chelonus insularis (3.9%) (Braconidae), Pristomerus spinator (1.1%), Campoletis sp. (0.3%) y Hyposoter sp. (0.1%) (Ichneumonidae) y un tachínido Archytas marmoratus (0.07%). Finalmente se aislaron dos hongos entomopatógenos, Beauveria bassiana (3.7%) y Nomuraea rileyi (8.9%) y un ucleopolyhedrovirus (11%) SfMNPV (Baculoviridae). El porcentaje de parasitismo total fue de 29.7%, lo cual genera un potencial de uso en programas de control biológico por conservación.
Descripción:
Thirteen-hundred larvae of Spodoptera frugiperda were collected from infested maize fields in Nayarit in 2011 and 2012. These larvae were examined for natural enemies. Six parasitoid species were found and identified such as Cotesia sp. (0.3%) and Chelonus insularis (3.9%) (Hymenoptera: Braconidae), Pristomerus spinator (1.1%), Campoletis sp. (0.3%) and Hyposoter sp. (0.1%) (Hymenoptera: Ichneumonidae), and one tachinid fly Archytas marmoratus (0.07%) (Diptera: Tachinidae). Also two entomopathogenic fungi were isolated: Beauveria bassiana (3.7%) and Nomuraea rileyi (8.9%), and one nucleopolyhedrovirus (11%) SfMNPV (Baculoviridae). Total percentage of parasitism was 29.7%, which generates a potential use in biological control programs by conservation.
