Abstract

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.

Özet

Bu çalışmada; toplam yedi farklı bakteri straini (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 ve Pseudomonas fluorescens KŞN-1) ve bir adet fungus izolatı (Beauveria bassiana ET-10) patates böceği (Leptinotarsa decemlineata Say)’nin ergin ve birinci, ikinci, üçüncü dönem larvalarına karşı biyolojik mücadelede etkinliğini belirlemek için sera koşullarında test edilmiştir. Sera denemelerinde en etkili bulunan üç bakteri straini ise tarla şartlarında denenmiştir. Sera denemeleri 5 tekerrürlü, tarla denemeleri ise 4 tekerrürlü olarak yapılmıştır. Çalışmadan elde edilen sonuçlara göre; sera koşullarında en etkili bulunan B. thuringiensis subsp. kurstakii FDP-41, B. brevis CP-1 ve P. fluorescens KŞN-1 strainleri, tarla denemelerinde birinci dönem larvalarda sırası ile %41,33, %20 ve %11,33, ikinci dönem larvalarda %20, %26,66 ve %4,66; üçüncü dönem larvalarında ise %10, %24,66 ve %6,66 ölüme sebep olmuştur. Ayrıca B. brevis CP-1 strainin ergin böceklerde etkili olmadığı fakat B. thuringiensis subsp. kurstakii FDP-41 ve P. fluorescens KŞN-1 strainleri sırası ile %30 ve %4 oranında ölüme sebep olduğu belirlenmiştir.
