SOIL AND DIAPREPES ABBREVIATUS ROOT WEEVIL SPATIAL VARIABILITY IN A POORLY DRAINED CITRUS GROVE

open access: closedSoil Science, 2004
Soil and water variability in space and time could be important for management of the citrus root weevil, Diaprepes abbreviatus (L.). We conducted a study of soil, tree, and root weevil relationships in a poorly drained grove of Hamlin orange on Swingle citrumelo rootstock (Citrus paradisi Macfad. x Poncirus trifoliata (L) Raf.).

Resistance of Eight Cultivars of Citrus Rootstock to a Larval Root Weevil, Diaprepes abbreviatus L. (Coleoptera: Curculionidae)

open access: closedJournal of Economic Entomology, 1995
To determine the potential for resistance (tolerance or antibiosis) to root weevil attack on citrus rootstocks, seedlings of eight citrus rootstock cultivars were challenged with young larvae of a root weevil, Diaprepes abbreviatus L. After 6 wk of feeding and development on root systems of potted plants in a greenhouse, soil and larvae were separated ...

Discovery and characterization of chemical signals for citrus root weevil, Diaprepes abbreviatus

Arthropod-Plant Interactions, 2009
The tropical root weevil Diaprepes abbreviatus (L. 1758) (Coleoptera: Curculionidae) is a polyphagous insect from the Caribbean Islands and an invasive insect in the southern part of the United States where it is pest of citrus crops and ornamental trees. Adults feed upon foliage where aggregation, mating and oviposition take place. Here, the headspace

WATER STRESS AND ROOT INJURY FROM SIMULATED FLOODING AND DIAPREPES ABBREVIATUS ROOT WEEVIL LARVAL FEEDING IN CITRUS

Soil Science, 2006
Environmental stress from flooding can occur simultaneously with root weevil infestation to damage plant root systems. We conducted two factorial studies of flooding duration and Diaprepes abbreviatus (L.) root weevil larval feeding injury on citrus in the greenhouse in 2002 and 2003.

Cross‐correlation patterns of air and soil temperatures, rainfall and Diaprepes abbreviatus root weevil in citrus

Pest Management Science, 2007
AbstractTime series cross‐correlation analysis is appropriate when measuring relationships between two different time series. Using this approach, the authors quantified the relationship between the time series air temperature (AT), soil temperature (ST), rainfall, relative humidity (RH) and Diaprepes abbreviatus (L.) (Coleoptera: Curculionidae) root ...
