Exploration in Belize for parasitoids attacking eggs of citrus weevils, and an evaluation of Pediobius irregularis and Horismenus bennetti (Hymenoptera: Eulophidae) as potential biological control agents of Diaprepes abbreviatus and Pachnaeus litus (Coleoptera: Curculionidae)
Florida Entomologist 85 (4), 660-663
Abstract: Two parasitoid species, Pediobius irregularis and Horismenus bennetti, were recovered from weevil eggs collected in citrus in Belize. Exophthalmus vitticollis was the principal weevil species observed in citrus during the trip. Under quarantine in Florida, P. irregularis parasitized eggs of the Florida citrus weevils Diaprepes abbreviatus and Pachnaeus litus, but few F1 adults were recovered and no F2 adults were produced. The research indicated P. irregularis held little promise as a candidate for a biological control program for either D. abbreviatus or P. litus and that H. bennetti held no promise at all.
