Entomopathogenic Nematodes for Control of Root Weevils of Citrus
The Florida Entomologist, 1992 The entomopathogenic nematodes, Steinernema carpocapsae (All strain), Heterorhabditis bacteriophora (HP-88 strain), H. bacteriophora (Florida strain), applied to the soil of a citrus grove near Lake Jem, Florida in March 1989, significantly reduced adult emergence of the root weevil, Diaprepes abbreviatus (L.).

Citrus Root Weevil Control on Citrus, 1988 [PDF]
Insecticide and Acaricide Tests, 1989 Abstract The experiment was conducted with a completely randomized block design of 2 trees/plot and was replicated 4 times. All treatments were applied with a John Bean sprayer at 300 psi to run-off. Wild adult weevils collected from the adjacent plantings were placed in screen limb bags (5 weevils/bag) which were attached to treated ...

Use of Landscape Fabric to Manage Diaprepes Root Weevil in Citrus Groves [PDF]
Florida Entomologist, 2009 ABSTRACT Experiments were conducted at 3 sites in Florida to determine whether landscape fabric, used as soil mulch, can reduce damage to citrus trees by Diaprepes abbreviates. The mulches were intended to prevent newly hatched weevil larvae from entering the soil to feed on roots and to prevent teneral adult weevils from exiting the soil to initiate ...

LADY BEETLES AS POTENTIAL PREDATORS OF THE ROOT WEEVIL DIAPREPESABBREVIATUS (COLEOPTERA: CURCULIONIDAE) IN FLORIDA CITRUS [PDF]
Florida Entomologist, 2002 Abstract 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.), Harmoniaaxyridis Pallas, and Olla v-nigrum Mulsant, are generalist predators that ...

A Review of Chemical Antagonists to Mycopathogens of Citrus Root Weevils
The Florida Entomologist, 1985 The literature describing chemical antagonists of the methypathogens that attack larvae of citrus root weevils is reviewed with emphasis on compounds that are either fungicidal or fungistatic and impact Beauveria bassiana or Metarhizium anisopliae. The development of antagonist-resistant strains is described.

Molecular Identification of the Economically Important Invasive Citrus Root WeevilDiaprepes abbreviatus(Coleoptera: Curculionidae) [PDF]
Florida Entomologist, 2009 The article reports on the study that identifies the economical importance of citrus root weevil Diaprepes abbreviatus (D. abbreviatus). It develops a sensitive barcoding technique based on the polymerase chain reaction (PCR)-amplification and sequencing of the mitochondrial cytochrome oxidase I (COI) gene to use in identification of eggs, larvae and ...
