The predatory capacity of isolates of the fungi Arthrobotrys robusta (I31), Duddingtonia flagrans (CG768) and Monacrosporium thaumasium (NF34A) on infective larvae (L3) of Ancylostoma spp. was evaluated in laboratorial conditions by 10 days in medium water-agar 2% (WA 2%) and in fecal cultures of feces of dogs. The conidia production for the isolates was analyzed in the means of WA 2%, potato-dextrose-agar 2% (PDA 2%), corn-meal-agar 2% (CMA 2%) and yeast-phosphate-sulphate-sucrose-agar (YPSSA). In relation to the control without fungi there was significant reduction (P <0,05) of 89,89%, 97,75% and 88,76% in the average of L3 of Ancylostoma spp. recovered from medium WA 2% of the plates of Petri in the treatments with isolates CG768, I31 and NF34A, respectively. The isolate I31 was the most effective in the capture of the L3. In the fecal cultures, the reduction in average of L3 of Ancylostoma spp. in the treatments was not significant (P> 0,05). The isolated I31 was also the most effective, reducing the average of recovered L3 in 32,04% while isolated NF34A and CG768 reduced in 15,36% and 7,30% the average of infective larvae, respectively in relation to the control without fungi. There was larger conidia production of the isolate CG768 in the medium PDA 2% while in isolates I31 and NF34A this production was larger in the medium YPSSA. The results evidence that these trapping fungi can be used in the control of the L3 of Ancylostoma spp. of dogs, however, the doses and the time of interaction fungus-nematode should be studied better.
