Augmentation of parasitoids for biological control of citrus blackfly in southern Texas
Florida Entomologist 87 (2), 186-193
Abstract: Two parasitoid species, Amitus hesperidum Silvestri and Encarsia opulenta (Silvestri), were released in an augmentative program to control citrus blackfly, Aleurocanthus woglumi Ashby, in the citrus growing areas of southern Texas. Releases were made with laboratory-reared and field insectary parasitoids. Six citrus groves were closely monitored, and evaluations made during and after releases suggested that both parasitoid species became reestablished and exerted control over pest populations. Dissection of citrus blackfly immatures led us to suggest that E. opulenta increased in larger numbers than A. hesperidum, and that a stable host-natural enemy relationship became established.
Dos especies de parasitoides, Amitus hesperidum Silvestri y Encarsia opulenta (Silvestri) fueron liberadas en un programa de aumentó para el control de la mosca prieta de los cítricos. Aleurocanthus woglumi Ashby, en áreas donde siembran los citricos en el sur de Texas. Las liberaciones fueron hechas usando parasitoides criados en el laboratorio y los del insectario del campo. Un monitoreo preciso de seis huertos de cítricos fue hecho, y las evaluaciones hechas durante y después de la liberación que sugerieron que ambas especies de parasitoides se re-establecieron y ejercieron un control sobre la población de la plaga. La disección de inmaduras de la mosca prieta de los cítricos tambien sugerió que el E. opulenta se aumento en números mas altos que el A. hesperidum, y que una relación estable entre el hospedero y el enemigo natural fue establecida.
