Distribution of fall armyworm (Lepidoptera: Noctuidae) parasitoids on five corn genotypes in south Georgia

Five genotypes of corn were planted on four different dates in south Georgia during the spring of 1991. Plants were infested with neonate fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), larvae and collected either seven or twelve days later. Larvae were reared in the laboratory on artifici...

description Five genotypes of corn were planted on four different dates in south Georgia during the spring of 1991. Plants were infested with neonate fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), larvae and collected either seven or twelve days later. Larvae were reared in the laboratory on artificial diet to determine distribution of FAW parasitoids. Larvae recovered from the resistant genotype MpSWCB-4 had the highest percent parasitism (44.30%), while the susceptible genotype Pioneer 3192 had the lowest parasitism (31.70%). Aleiodes laphygmae (Gahan) was the most abundant parasitoid, attacking a total of 12.8% of the 16,120 FAW larvae recovered. Archytas marmoratus (Townsend) parasitized 10.0% of the FAW larvae while Ophion flavidus Brullé and Cotesia marginiventris (Cresson) parasitized 7.9% and 6.3%, respectively, of the recovered FAW. Ten additional parasitoid species emerged from the FAW, but none of these species attacked more than 1% of the recovered FAW larvae. /// Se plantaron cinco genotipos de maíz en cuatro fechas diferentes en el sur de Georgia durante la primavera de 1991. Las plantas fueron infestadas con larvas pequeñas del cogollero del maíz (FAW), Spodoptera frugiperda (J. E. Smith) colectadas siete o doce días después. Las larvas fueron criadas en el laboratorio en una dieta artificial con el fín de determinar la distribución de los parasitoides de FAW. Las larvas recolectadas del genotipo resistente MpSWCP-4 tuvieron el porcentaje mas alto de parasitismo (44.30%), mientras que el genotipo susceptible Pioneer 3192 tuvo el parasitismo mas bajo (31.70%). Aleiodes laphygmae (Gahan) fue el parasitoide mas abundante, atacando un total de 12.8% de 16,120 larvas de FAW. Archytas marmoratus (Towsend) parasitó 10.0% de las larvas de FAW, mientras que Ophion flavidus Brulle and Cotesia margiventris (Cresson) parasitaron 7.9% y 6.3% de las larvas de FAW, respectivamente. Diez especies mas de parasitos emergieron de FAW, pero ninguna de estas especies atacó mas del 1% de las larvas de FAW.
