A New Fidiobia Species (Hymenoptera: Platygastridae) Reared From Eggs of Diaprepes Doublierii (Coleoptera: Curculionidae) From Dominica

“…native egg parasitoids found attacking this weevil in citrus orchards in Florida(Hall et al 2001) and past failures of classical biological control of this weevil(Beavers et al 1980), renewed efforts were initiated to introduce, release, and evaluate candidate egg parasitoids from the Caribbean Region into Florida(Peña et al 1998;Hall et al 2002). For instance, Brachyufens…”

Effect of Micromite® on the Egg Parasitoids Ceratogramma Etiennei (Hymenoptera: Trichogrammatidae) and Quadrastichus Haitiensis (Hymenoptera: Eulophidae)

“…Micromite has been described as a foundation product for reducing citrus root weevil populations, in part due to its compatibility with root weevil natural enemies (Anonymous 1996). However, there are no reports on the effect of micromite on egg parasitoids that have been imported and established for biological control of D. abbreviatus (Hall et al 2001;Peña et al 2000;Peña et al 2003). A study was initiated to evaluate the impact of Micromite on Ceratogramma etiennei Delvare and Quadrastichus haitiensis (Gahan), two egg parasitoids of Diaprepes root weevil.…”

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)

“…The trip, organized by coauthors Peña and Hall and funded by a grant from the Florida Citrus Production Research Advisory Council (981-42E), was made in hopes of finding parasitoid species that could be introduced into Florida to boost biological control of the Diaprepes root weevil, Diaprepes abbreviatus (L.), a major pest of citrus ( Citrus spp.) and ornamental plants in Florida (Hall et al 2001). No parasitoids are known to attack eggs of D. abbreviatus in Florida (Hall et al 2001).…”

“…and ornamental plants in Florida (Hall et al 2001). No parasitoids are known to attack eggs of D. abbreviatus in Florida (Hall et al 2001). Attempts in Florida to establish egg parasitoids that attack D. abbreviatus in Guadeloupe ( Ceratogramma etiennei Delvare, Hymenoptera: Trichogrammatidae), Puerto Rico ( Quadrastichus haitiensis Gahan) and the Dominican Republic ( Aprostocetus vaquitarum (Wolcott)) (Hymenoptera: Eulophidae) have been made (e.g., see Hall et al 2001, Peña et al 2000.…”

“…The majority of time spent at each citrus location was devoted to searching citrus leaves for weevil egg masses. Specifically, we looked for weevil egg masses glued between two juxtaposing leaves (Hall et al 2001). A total of 168 egg masses were found; these ranged from freshly deposited to possibly several weeks old.…”
