[In vitro nematophagous capacity of Duddingtonia flagrans maintained under 2 conditions of preservation].

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.
