Effect of Low Temperatures on Mortality and Oviposition in Conjunction With Climate Mapping to Predict Spread of the Root Weevil <I>Diaprepes abbreviatus</I> and Introduced Natural Enemies [PDF]

Environmental Entomology, 2007
The tropical root weevil, Diaprepes abbreviatus (L.), has been a pest of citrus and ornamental plants since its introduction into Lake County, FL, in 1964. Since then, it has colonized the Florida peninsula to the south of its point of introduction but has not expanded its range to the north. A lower threshold for oviposition by D.

Time series forecast and soil characteristics-based simple and multivariate linear models for management of Diaprepes abbreviatus root weevil in citrus

, 2020
Synthesis of insect and soil variable patterns in space and time via process models would be useful for reducing the cost of field monitoring and for achieving improved integrated pest management. During 2001-2003, we monitored the Diaprepes abbreviatus (

Molecular Identification of the Economically Important Invasive Citrus Root WeevilDiaprepes abbreviatus(Coleoptera: Curculionidae)

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 ...
