Efficacy of Topical Application, Leaf Residue or Soil Drench of Blastospores of Isaria fumosorosea for Citrus Root Weevil Management: Laboratory and Greenhouse Investigations. [PDF]
The efficacy of topical, leaf residue, and soil drench applications with Isaria fumosorosea blastospores (Ifr strain 3581) was assessed for the management of the citrus root weevil, Diaprepes abbreviatus (L.).

Predators of Diaprepes abbreviatus (Coleoptera: Curculionidae) Larvae
Larvae of Diaprepes abbreviatus (L.) in petri dishes were susceptible to predation on the soil surface in a citrus grove. An average of 47% were removed by predators in the first 20 minutes in a 1979 study to determine rates of predation. Predators (2,613 recorded events) were exclusively ants in the grove studied, with the exceptions of 2 predation ...

Particle film deters oviposition by Diaprepes abbreviatus (Coleoptera: Curculionidae).
A hydrophilic formulation of the inert silicate kaolin was tested in a screenhouse for its effect on the behavior of the root weevil Diaprepes abbreviatus (L.), a pest of citrus and ornamental plants in Florida and the Caribbean. Feeding by adults on treated foliage was reduced by 68-84% compared with adults fed untreated foliage.

Metagenomic clustering reveals microbial contamination as an essential consideration in ultraconserved element design for phylogenomics with insect museum specimens. [PDF]
We investigate if genomic bacterial and laboratory contamination is introduced into ultraconserved element (UCE) probe design from five novel Coleoptera museum specimens. Our findings indicate that even very clean samples have contamination that is carried into the UCE probe design.

Effect of Soil Moisture on Development of Diaprepes abbreviatus (Coleoptera: Curculionidae)
We conducted trials to determine conditions of soil moisture required to optimize production of adults of Diaprepes abbreviatus (L.) in a laboratory colony. Larvae of D. abbreviatus were reared on a commercially available artificial diet and then placed in soil with water content ranging from 20 to 80%. Optimal moisture content of soil for pupation was

Plants use identical inhibitors to protect their cell wall pectin against microbes and insects
Whether polygalacturonase‐inhibiting proteins (PGIPs) play a role in defense against herbivorous beetles is unknown. Feeding assays with the leaf beetle Phaedon cochleariae on Arabidopsis thaliana pgip mutants were performed. Fitness was increased when larvae were fed on mutant plants compared to wild‐type plants.

Field Diagnosis of Citrus Root Weevil Damage
Root weevils infest citrus groves throughout the citrus growing regions of Florida. Among the eight weevil species that have been identified in Florida citrus groves, five have some potential to cause economic problems for nurserymen and commercial ...
