In this study, effects of four different biopesticides (Priority, Nimbecidine, Nostalgist, Bio-Magic ve Bio-Catch) and a plant extract (Nimbedicine), and also for comparison Chlorpyrifos-ethyl, on Myzus persicae (Sulzer) (Hemiptera: Aphididae) were investigated by spraying method under the loboratory conditions. Experiments were performed with two different methods (petri dishes and pots) in Suleyman Demirel University, Agricultual Faculty, Biological Control Research and Applying Laboratory of Plant Protection Department. The preparats were applied as spray in pepper leaves placed in petri dishes and pepper plants in pots. After 10 minutes, 10 individuals were transferred into each petri dish and 5 aphids were placed into one leaf of each plant than 15 aphids were infested to 3 leaves of the each plant. Petri dishes and pots experiments were established with 10 and 4 replicates, respectively. After the applications, the counts were made on the 1st, 3rd, 5th and 7th days in the petri dishes and only on the 7th day in the pots. Live and dead individuals were recorded. As a result of the study, the effects to M. persicae of Bio-Catch, Bio-Magic, Nostalgist, Priority, Nimbedicine and Chlorpyrifos-ethyl according to Abbott in the petri dishes experiments were 39%, 35%, 47%, 39%, 68% and 100%, respectively on day 7th. In pot experiments, this effect is %44.44, %42.59, %53.70, %37.04, %68.52 ve %100.00 on day 7th. As a result, the most effective Chlorpyrifos-ethyl was found on M. persicae in both petri dishes and pot experiments, followed by Nimbedicine. The effects of bioinsecticides were similar.
