This work has been done for the purpose of creating a complete struggle strategy against Pristiphora abietina (Christ), which is the cause of the spoil in Artvin Savsat spruce forests in the recent years and Pyrethrum and Bacillus thuringiensis biopesticides effects has been investigated and put into practice on the P. abietina. Under laboratory conditions, Pyrethrum (Spruzit Neu) and B. thuringiensis (Dipel DF) biopesticides were administered at different doses to the larvae of P. abietina and the results were evaluated according to the One Way Analysis of Variance and Duncan Test. The most effective applications for larval applications have been determined that Dipel 100 gr / 100 lt, Dipel 300 gr / 100 lt and Dipel 500 gr / 100 lt. The Pyrethrum (Spruzit Neu) efficiency ratio was determined 71.7% dose of 150 ml / 100 lt, 81% dose of 300 ml / 100 lt, 93.2% dose of 600 ml / 100 lt and Dipel DF was found to be 91.5% dose of 100 g / 100 lt, 93.6% dose of 300 gr / 100 lt and 98.8% dose of 500 gr / 100 lt, respectively. As a result, using of both biopesticides have been effective to against on larvae of P. abietina.
