First report in Colombia and diagnosis of Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae), a parasitoid wasp of Diaphorina citri (Hemiptera: Liviidae)
2022
Overview
Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae) is herein reported for the first time from Colombia based on specimens collected in the municipality of Palmira, department of Valle del Cauca. Adult male and female wasps of this endoparasitoid are diagnosed based on published literature and character states taken from specimens collected in the present study. The adult parasitoids were extracted from parasitized nymphs (mummies) of the Asian citrus psyllid, Diaphorina citri (Hemiptera: Liviidae). Information is provided on the differences in the morphology of parasitized nymphs of D. citri with exit holes made by the two main primary parasitoids, i.e., Tamarixia radiata (Hymenoptera: Eulophidae) and D. aligarhensis. Rates of parasitization on D. citri ranged from 1.5 to 24.2 % for T. radiata and 0.3 to 1.0 % for D. aligarhensis. With the present study, the presence of D. aligarhensis in Colombia becomes the second confirmed report of the species in South America, after Ecuador.
Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae) se reporta por primera vez en Colombia con base en especímenes recolectados en el municipio de Palmira, departamento del Valle del Cauca. Los machos y hembras adultos del endoparasitoide D. aligarhensis se diagnostican con base en la literatura publicada y los estados de carácter tomados de las muestras recolectadas en el presente estudio. Los parasitoides adultos se extrajeron de ninfas parasitadas (momias) del psílido asiático de los cítricos, Diaphorina citri (Hemiptera: Liviidae). También se proporciona información sobre las diferencias en la morfología de las ninfas parasitadas de D. citri con orificios de salida de los dos principales parasitoides primarios, i.e., Tamarixia radiata (Hymenoptera: Eulophidae) y D. aligarhensis. Las tasas de parasitismo en D. citri variaron entre 1,5 y 24,2 % para T. radiata y entre 0,3 y 1,0 % para D. aligarhensis. Con el presente estudio, la presencia de D. aligarhensis en Colombia se convierte en el segundo reporte confirmado de la especie en América del Sur después de Ecuador.
