Metcalfa pruinosa (Say) is one of the important harmful insect species of the coastal areas of Eastern Black Sea Region. This insect poses a danger by feeding on the juices of hundreds of plants in the region. This study was designed to create a fight strategy against M.pruinosa, which has posed an intense danger in Artvin - Kemalpaşa in recent years, and the effect of Spruzit Neu and Dipel biopesticides on the nymphs and adults of the insect was investigated, and the applicability of these biopesticides was revealed. The study was conducted in the summer season of 2016 when the nymphs and adults of the insect are abundant in the region. In in vitro conditions, the Spruzit Neu (Pyrethrum) and Dipel DF (Bacillu thuringiensis) biopesticides were sprayed at different doses (DiPel® DF BT 100gr / 100lt, Dipel® DF BT 300gr / 100lt, Dipel® DF BT 500gr / 100lt ve Spruzit® Neu) on the nymphs and adults of the insect. The adults and nymphs were checked with 2-day intervals, and the results were assessed according to the One-Way Variance Analysis (ANOVA) and the Duncan Test. It was determined that the most effective applications for the nymphs were Dipel DF 300gr/100lt and 500gr/100lt. It was also determined that the most effective applications for the adult individuals were Spruzit Neu 600ml/100lt and Dipel DF 500gr/100lt doses. The highest death rates in the nymphs were determined in Spruzit Neu 600ml/100lt dose as 72,5%; and in Dipel DF dose as 80%. These rates were determined in Pyrethrum 600 ml/100lt dose as 78%, and in Dipel DF 500 gr/100lt dose as 75%. As a conclusion, it was determined that both biopesticides are influential on the nymphs and adults of M.pruinosa. However, it was also determined that the fight will be more influential in the nymph period of the insect.
