Reproductive biology of Fidiobia dominica (Hymenoptera: Platygastridae), an egg parasitoid of Diaprepes abbreviatus (Coleoptera: Curculionidae).
The reproductive biology of Fidiobia dominica Evans (Hymenoptera: Platygastridae) was studied in the laboratory (25.6 +/- 1 degrees C) using host eggs of Diaprepes abbreviatus L. (Coleoptera: Curculionidae). F. dominica readily parasitized D. abbreviatus eggs on both host plant and wax paper substrates. The number of egg masses parasitized and the number of offspring produced were higher when f...
متن کاملEffect of temperature on life history of Quadrastichus haitiensis (Hymenoptera: Eulophidae), an endoparasitoid of Diaprepes abbreviatus (Coleoptera: Curculionidae)
The influence of temperature on life history traits of the egg parasitoid Quadrastichus haitiensis (Gahan) (Hymenoptera: Eulophidae) was investigated in the laboratory on eggs of the root weevil Diaprepes abbreviatus (L.) (Coleoptera: Curculionidae). Duration of development from egg to adult decreased from 39.99 ± 0.27 days to 13.57 ± 0.07 days (mean ± SE) as temperature increased from 20 to 33...
متن کاملReduced oviposition by Diaprepes abbreviatus (Coleoptera: Curculionidae) and growth enhancement of citrus by Surround particle film.
Regularly applied sprays of a particle film, Surround WP, greatly enhanced the growth of citrus trees on a poorly drained Winder soil at Fort Pierce, FL. After 3 yr of applications every 3 or 4 wk, Surround-treated trees had at least 5 times the mass, 6 times the canopy volume, and approximately 4 times the cross-sectional area of the tree stems at the graft union compared with untreated trees....
متن کاملIs there meaningful plant resistance to diaprepes abbreviatus (Coleoptera: Curculionidae) in citrus rootstock germplasm?
Host plant resistance to the Diaprepes root weevil, Diaprepes abbreviatus (L.) was assessed for seedlings of 54 Poncirus trifoliata (L.) Raf. selections and two families of progeny from crosses between Citrus and P. trifoliata. Weight gain was consistently lower when larvae were reared in pots containing the progeny of Citrus reticulata Blanco 'Sunki' x P. trifoliata 'Flying Dragon' compared wi...
متن کاملLady Beetles as Potential Predators of the Root Weevil Diaprepes Abbreviatus (coleoptera: Curculionidae) in Florida Citrus
Diaprepes abbreviatus (L.) is a major pest of Florida citrus. Adult females lay eggs in masses sealed between leaves in the citrus canopy, and recently-hatched neonate larvae drop to the soil and feed on roots. The coccinellid species, Cycloneda sanguinea (L.), Harmonia axyridis Pallas, and Olla v-nigrum Mulsant, are generalist predators that consume a wide range of citrus pests, although they ...
