Abstract

Three formulations of Bacillus thuringiensis Berliner, preparation Thuricide® were evaluated against a commonly occurring leafroller, Archips rosanus (L.), on filberts. In the laboratory at 26.7 ± 1 °C, all larvae died within 7 days after feeding for 48 h on filbert leaves treated with dust and wettable formulations. With aqueous concentrate, the mortality was slightly less. Insect susceptibility was markedly reduced when the length of feeding exposure period was decreased. In the field, the infestation of A. rosanus was significantly reduced within a week after treatment in almost all the treated plots. Larval mortality continued for about 4 weeks. Under western Oregon conditions, dust treatments were slightly better than wettable or aqueous concentrate formulations.
