Quality control of in vitro produced Heterorhabditis bacteriophora (Rhabditida: Heterorhabditidae) strains isolated from Turkey

H.b. 6 (Antalya), H.b. 17 (Kirklareli), H.b. 10 (Adana), H.b. HIZ (Izmir), H.b. HSU (Sanliurfa) and H.b. 876 (canakkale) strains of Heterorhabditis bacteriophora Poinar, 1976 (Rhabditida: Heterorhabditidae), were produced with in vivo and in vitro mass production techniques. Effectiveness and reproduction capacities of the nematodes obtained from in vivo and in vitro cultures were compared in order to determinethe quality of in vitro productionThe difference in infectivity of the strains produced with in vivo and in vitro techniques was not statistically significant, except H.b. 6, which was lower in in vitro. Some in vitro produced strains had significantly higher reproduction capacity than in vivo strains but some strains were not significantly different as in vivo produced strains. It was generally detected that the in vitro cultured Turkish strains maintained their prerequisites on effectiveness and reproduction capacities as their quality control standards.
