Cuticular hydrocarbons on elytra of the Diaprepes root weevil Diaprepes abbreviatus (L.) (Coleoptera: Curculionidae)
1 External gland openings and associated structures on the elytra of teneral and mature Diaprepes root weevils, Diaprepes abbreviatus (L.), were elucidated by scanning electron microscopy (SEM). 2 There were clear differences between teneral, callow adults and fully mature adults. In the field, teneral adults remain in the pupal chamber in the soil until sclerotization of the cuticle is complet...
متن کاملIridovirus 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 کاملIridovirus infection of cell cultures from the Diaprepes root weevil, Diaprepes abbreviatus
We here report the development and viral infection of a Diaprepes root weevil cell culture. Embryonic tissues of the root weevil were used to establish cell cultures for use in screening viral pathogens as potential biological control agents. Tissues were seeded into a prepared solution of insect medium and kept at a temperature of 24 degrees C. The cell culture had primarily fibroblast-like mo...
متن کاملControlling factors of environmental flooding, soil pH and Diaprepes abbreviatus (L.) root weevil feeding in citrus: Larval survival and larval growth
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). Our objectives were to determine the combined effects of soil flooding and pH level on survival and growth of Dia...
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...
