Özet
Bu çalışmada Nezara viridula (L.)’nın biber, domates ve fasulye bitkileri arasındaki tercihinin ortaya konması amaçlanmıştır. Bu amaçla, üç farklı bitkinin de bulunduğu kafes içerisine salım yapıldıktan sonra 4. saatte gözlemler yapılmıştır. Zararlının besin tercihi, her bitkinin gövde, yaprak veya meyvesi üzerinde ve bitki dışında bir yerde bulunan bireylerin ortalama sayıları ve her bir bitkideki bireylerin oranları kullanılarak biyolojik dönemlere göre ayrı ayrı incelenmiştir. Denemeler 25±1°C sıcaklık, %45±5 orantılı nem ve aydınlanma süresi 16:8 saat olan koşullara göre hazırlanmış iklim odasında yapılmıştır. Çalışma sonuçlarına göre, zararlı tarafından fasulye bitkisinin %44.1 oranında, domates bitkisinin %33.5 oranında ve biber bitkisinin %22.5 oranında tercih edildiği ortaya konmuştur. Ayrıca, biber bitkisini %8.7 oranla II. nimf dönemindeki bireyler en az tercih ederken, %36.8 oranla ergin erkek bireyler en çok tercih edenler olmuşlardır. Domates bitkisini en çok ergin erkek bireyler tercih ederken %17.6 oranıyla II. nimf dönemindeki bireyler ise en az tercih eden bireyler olmuşlardır. Fasulye bitkisini en çok II. nimf dönemindeki bireyler %73.7 oranıyla tercih ederken %8.7 oranıyla ergin erkek bireyler en az tercih edenler olmuşlardır.
The study aimed to find out the preference among pepper, tomato and bean plants, of Nezara viridula (L.). For this purpose, observations were made at the 4th hour after the release of individuals. Food preference of the pest was investigated for each of all biological stages separately, using the average numbers of individuals located on stem, leaf or fruit organs of each plant and anywhere in the cage and percentage of individuals on the preferred plants. Experiments conducted in a controlled climate room conditions at temperature 25±1°C, relative humidity 45%±5% and photoperiod 16:8 h. The study shows that bean, tomato and pepper were preferred by N. viridula respectively with 44.1%, 33.5% and 22.5%. Also, pepper was preferred the least by the second-stage nymphs with 8.7% while it was preferred the most by male adults with 36.8%. Tomato was preferred the most by male adults while it was preferred the least by the secondstage nymphs with 17.6%. Bean was preferred the most by the second-stage nymphs with 73.7% while it was preferred the least by male adults with 8.7%.
