چکیده

In this study; a total of seven bacterial strains (bacillus cereus fd-63, bacillus sphaericus fd-49, bacillus subtilis ek-7, bacillus thuringiensis subsp. kurstakii fdp-41, brevibacillus brevis cp-1, pseudomonas chlororaphis nem-28 and pseudomonas fluorescens kşn-1) and one fungus isolate (beauveria bassiana et-10) were tested for determining of biological control activity against on mature (leptinotarsa decemlineata say) and on 1., 2. and 3. larvae stages in greenhouse conditions. the most effective three bacterial strains in greenhouse conditions were tested for in field conditions. geenhouse experiments were carried out with 5 replications and field experiments with 4 replicates. according to the results obtained from the study; the most effective b. brevis cp-1, b. thuringiensis subsp. kurstakii fdp-41 and p. fluorescens kşn-1 strains in greenhouse conditions caused death 41.33%, 20% and 11.33% in the first period larvae; 20%, 26.66% and 4.66% respectively in the second stage larvae; 10%, 24.66% and 6.66% in the third stage larvae in the field conditions, respectively. in addition, it was determined that b. brevis cp-1 was not effective in mature insects but b. thuringiensis subsp. kurstakii fdp-41 and p. fluorescens kşn-1 strains caused death %30 and %4, respectively.
