Turkish Journal of Agriculture and Forestry

This study was conducted to determine the effect of Bacillus thuringiensis var. kurstaki on the larvae of Thaumetopoea solitaria in the search for an alternative control method with minimal undesirable side effects. Four larval stages were tested with various concentrations of the bacterium under controlled conditions by dipping pistachio saplings in relevant suspensions and feeding larvae on their leaves. The effect of B. thuringiensis var. kurstaki was significantly higher on the 1^{st} instar larvae than on the 2^{nd} and the 3^{rd} instar larvae, and the effect was significantly higher on the 2^{nd} instar larvae than on the 3^{rd} instar larvae. …
