Evaluation of the reproductive potential and comppetition between two entomopathogenic nematodes, steinernema feltiae filipjev,1934 (Rhabditida:Steinernematidae) and heterorhabditis bactriophora,poinar 1976 (Rhabditida:Heterorhabditidae)

Steinernema feltiae ve Heterorhabditis bacteriophora ile enfekte olan Galleria mellonelia larvalarından enfektif juvenil çıkışı, S. feltiae'de karşı karşıya kaldıktan 9 gün sonra, H. bacteriophora da ise 6 gün sonra başladı. Her bir konakta gelişen nematodların ortalama sayısı 13.829 olup S. feltiae enfeksiyonu için bu sayı 4365 ile 27.510 arasında değişti. Konak başına düşen ortalama nematod sayısı 141.562 olup H. bacteriophora enfeksiyonu için bu sayı 50.905 ile 271.593 arasındadır. İki farklı tür aynı anda aynı konağa inoküle edildiğinde, H. bacteriophora S. feltiae'den daha fazla ölüme neden olmuştur.Aynı konağa farklı zamanlarda iki farklı nematod türünün uygulanması sonucunda gözlenen yüksek ölüm oranlarından, her durumda ilk olarak ortalama verilen nematod türü sorumludur.

Steinernema feltiae filipjev,1934 (Rhabditida:Steinernematidae) and heterorhabditis bactriophora,poinar 1976 (Rhabditida:Heterorhabditidae) arasındaki üreme potansiyeli ve rakabetin değerlendirilmesi

The emergence in Galleria mellonelia (I.) larva, which was infected by Steinernema feltiae and Heterorhabditis bacteriophora, began on the ninth day after exposure to the former nematode and the sixth day of exposure to the latter nematode (25 ± 0.5 °C). The average number of nematodes developing in each host was as 13,829, and the range was from 4365 to 27,510 for S. feltiae infection. The average number of nematodes per host was 141,562, and the range was 50,905 - 271,593 for H. bacteriophora infection. When the 2 different species were inoculated simultaneously into the same host, H. bacteriophora caused higher mortality rates than S. feltiae. As a result of the application of 2 nematode species to the same host at different times, the first nematode species to be inoculated was responsible for the highest mortality rate in all cases.
