Comparison of Two Steinernematid Species for Control of the Root Weevil Diaprepes abbreviatus.

open access: yesJournal of nematology, 2011
Steinernema carpocapsae Weiser All strain was compared to Steinernema riobravis Cabanillas, Poinar, and Raulston for control of the root weevil, Diaprepes abbreviatus (L.), in the laboratory and in potted citrus. In the laboratory bioassay, D. abbreviatus larvae were exposed to 30, 60, and 120 nematodes/cm(3) in sand.

Use of Landscape Fabric to Manage Diaprepes Root Weevil in Citrus Groves

open access: yesFlorida Entomologist, 2009
ABSTRACT Experiments were conducted at 3 sites in Florida to determine whether landscape fabric, used as soil mulch, can reduce damage to citrus trees by Diaprepes abbreviates. The mulches were intended to prevent newly hatched weevil larvae from entering the soil to feed on roots and to prevent teneral adult weevils from exiting the soil to initiate ...
