Title
Enhancement of Bacillus thuringiensis with monosodium glutamate against larvae of obliquebanded leafroller (Lep.:Tortricidae)
Abstract
Monosodium glutamate, a taste enhancer widely used in food industry, was tested in the laboratory to determine its phagostimulatory effects on larvae of Choristoneura rosaceana (Harris). Larvae fed apple leaves treated with 50–700 μg/l monosodium glutamate increased leaf tissue consumption by approximately 40%. The stimulatory effect of monosodium glutamate (at 675 μg/l concentration) was maintained throughout 10 days of continuous exposure. Adding 675 μg/l monosodium glutamate to commercial formulation of Bacillus thuringiensis ssp. kurstaki, (DiPel®2X DF), lowered LC50 from 450 to 150 μg/l (P < 0.05, Lethal Ratio Significance Test), indicating good potential for monosodium glutamate to enhance B. thuringiensis‐based formulations.
