Iridovirus in the root weevil Diaprepes abbreviatus
Invertebrate iridescent virus 6 (IIV6) was evaluated for mode of transmission and ability to cause infection in the root weevil, Diaprepes abbreviatus (L.). This is the first evidence of IIV6 infection in D. abbreviatus, which caused both patent and sub-lethal covert infections in both larvae and adults. Adults and larvae were successfully infected with IIV6 by puncture, injection and per os. T...
متن کاملImpact of Surfactants on Control of the Root Weevil Diaprepes abbreviatus Larvae with Steinernema riobravis.
A filter paper bioassay was developed for testing the efficacy of nematodes and other agents for control of Diaprepes abbreviatus larvae. Surfactants, with and without Steinernema riobravis, were screened first in the filter paper bioassay and then in a potted citrus seedling study. The results of the two assays were in agreement on the relative merits of the compounds tested. Surfactants incre...
متن کاملComparison of Two Steinernematid Species for Control of the Root Weevil Diaprepes abbreviatus.
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. Insect mortality 1 week after application was greater (P </= 0.05) for S. rio...
متن کاملArrestment behavior in the polyphagous tropical root weevil Diaprepes abbreviatus.
A semiochemical-based attractant for the tropical root weevil, Diaprepes abbreviatus L., has been sought since the introduction of this polyphagous pest to Florida in the 1960s. A six-unit wind tunnel apparatus was constructed to allow multiple runs to be conducted simultaneously to test the response of D. abbreviatus adults to volatile and contact semiochemicals. Arrestment was measured as the...
متن کاملRoot deformation reduces tolerance of lodgepole pine to attack by Warren root collar weevil.
Surveys were conducted on regenerating stands of lodgepole pine to determine the relationship between root deformation and susceptibility to attack by the Warren root collar weevil, Hylobius warreni Wood. The total number of trees attacked by H. warreni did not differ between planted and natural trees. A matched case-control logistic regression suggested that root cross-sectional area was more ...
