Bu çalışmanın amacı 4 farklı bitki türü Elaeagnus rhamnoides, Quercus cerris, Coryllus maxima veCrataegus monogyna ile besleyerek Bacillus thuringiensis subsp. kurstaki tarafından enfekte edilenMalacosoma neustria larvalarının hayatta kalmasına ve bazı bağışıklık enzimlerine bitkilerdeki krom,nikel, bakır ve çinko metal iyonlarının etkisini araştırmaktır. Düşük nikel miktarına sahip Q. cerris ve C.monogyna bitkileriyle beslenen larvalarda hayatta kalma oranı yüksek nikel miktarına sahip olan E.rhamnoides ve C. maxima’ya göre daha düşüktür. En yüksek bakır miktarına sahip Q. cerris bitkisi ilebeslenen larvalarda katalaz enzimi diğer bitkilerle beslenen larvalara göre yüksektir. En yüksek çinko veen düşük nikel miktarına sahip olan C. monogyna ile beslenen larvalarda glutatyon peroksidaz aktivitesien yüksektir. Düşük çinko ve yüksek nikel miktarına sahip olan E. rhamnoides ile beslenen larvalarda endüşük glutatyon peroksidaz aktivitesi bulunmuştur. En yüksek çinko içeren C. monogyna ile beslenenenfekte edilmiş larvalarda süperoksit dismutaz aktivitesi en yüksektir. Yüksek nikel ve bakır miktarınasahip E. rhamnoides ile beslenen larvalarda hemosit sayısı en yüksektir. En düşük hemosit sayısı ise nikelve bakır miktarının en az olduğu C. monogyna bitkisi ile beslenen larvalarda bulunmuştur. In this study, Malacosoma neustria larvae infected by Bacillus thuringiensis subsp. kurstaki were fedwith 4 different types of plant species, Elaeagnus rhamnoides, Quercus cerris, Coryllus maxima andCrataegus monogyna, in order to see the effects of chromium, nickel, copper and zinc heavy metal ionsin plants on the survival and the immune enzymes of these larvae. The larvae fed the C. monogyna plantwith the highest zinc content had the lowest survival rate. In the infected groups, the catalase enzymeactivity was the highest in larvae fed with the Q. cerris plant, which has a high chromium content, andthe lowest in the larvae fed with E. rhamnoides. In the larvae fed with the highest copper-containing Q.cerris plant, the catalase enzyme was higher than the larvae fed with other plants. The larvae fed with C.monogyna with the highest zinc content had the highest glutathione peroxidase activity. The lowestglutathione peroxidase activity was found in the larvae fed with E. rhamnoides having low zinc content.Superoxide dismutase activity was the highest in the infected larvae fed with the highest zinc containingC. monogyna. The highest number of hemocytes were found in the larvae fed with E. rhamnoidescontaining high amounts of nickel and copper, while the lowest hemocyte count was found in larvae fedwith C. monogyna plant, where the amount of nickel and copper was the lowest.
