[In vitro nematophagous capacity of Duddingtonia flagrans maintained under 2 conditions of preservation]. / Capacidad nematófaga in vitro de Duddingtonia flagrans Mantenido en dos Condiciones de Preservación.

One trial was carried out to evaluate the nematophagous capacity of two Duddingtonia flagrans cultures, one maintained during one year at laboratory temperature and the other one was a recent culture, twelve Petri dishes with flour-corn-agar media were seeded with the 1YC another 12 Petri dishes were inoculated with the RC. Both were added with 150 larvae/dish of the free living nematode Panagrellus redivivus and 12 fluor-corn-agar dishes only with the free living nematode were used as a control. The results showed that the nematophagous capacity of both cultures were similar but it was statistically different (p < 0.05) with respect to the control group. It was concluded that the nematophagous capacity of D. flagrans was not affected in spite of being kept one year at laboratory temperature.
