Associations of soil iron with citrus tree decline and variability of sand, soil water, pH, magnesium and Diaprepes abbreviatus root weevil: Two-site study

Environmental and Experimental Botany, 2007
The hypothesis of associations of environmental soil heterogeneity with citrus tree decline and Diaprepes abbreviatus (L.) root weevil variability was tested in two flatwoods fields of ‘Hamlin’ orange trees (Citrus sinensis (L.) Osb.). Studies were conducted on a loamy, poorly drained Mollisol in Osceola County, central Florida in 2002, and on a sandy,

Controlling factors of environmental flooding, soil pH and Diaprepes abbreviatus (L.) root weevil feeding in citrus: Larval survival and larval growth

Applied Soil Ecology, 2007
Abstract The underlying influences of soil flooding, pH level and soil-inhabiting Diaprepes abbreviatus (L.) root weevil larval feeding in citrus were examined in two separate greenhouse studies, rootstock × flooding × Diaprepes-larvae (RFD) and liming × rootstock × flooding × Diaprepes-larvae (LRFD).
