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

Journal 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 ...

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.

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

Soil 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.).

Citrus Root Weevil Control on Citrus, 1988

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 ...

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 ...

Dehydrothalebanin:  A Source of Resistance from Glycosmis pentaphylla against the Citrus Root Weevil Diaprepes abbreviatus

Journal of Agricultural and Food Chemistry, 2000
Roots of a citrus relative, Glycosmis pentaphylla (orangeberry), were shown to inhibit the growth and survival of larvae of the citrus root weevil Diaprepes abbreviatus. Roots of G. pentaphyllaincorporated into the diet of D. abbreviatus increasingly inhibited the growth of neonate larvae with increased concentration of roots, while roots from citrus ...
