Abstract
Field trials with Bacillus thuringiensis Berliner for control of paramyelois transitella (Walker) were conducted in commercial almond orchards in California. B. thuringiensis formulated as Dipel® (2% dust and WP), Thuricide® HPC (EC), and Biotrol® XK (WP) was applied starting at about the onset of hullcrack for 4–5 applications at 3–10 day intervals. A synthetic feeding stimulant, Mo-Bait,® also was tested. The highest level of control (44.8% damage reduction) was obtained with 4 applications of Thuricide HPC at a rate of 1 qt/25 trees. The addition of the feeding stimulant did not increase the effectiveness of the treatments. Navel orangeworms are difficult to control because they apparently move to the deeper areas of the hull-shell interspace that are not penetrated by the treatments.
