Larvicidal activity of a crude enzyme extract of the fungus Duddingtonia flagrans on first-stage larvae of Angiostrongylus vasorum

INTRODUCTION: Angiostrongylus vasorum is a nematode parasite of domestic dogs and potentially of humans. METHODS: This study aimed to observe the predatory activity in vitro of a crude enzyme extract of the fungus Duddingtonia flagrans on first-stage larvae of A. vasorum in laboratory conditions on 2% water-agar. RESULTS: At the end of the experiment, the percentage reductions observed for A. vasorum L1 were 53.5% (24h) and 71.3% (48h). CONCLUSIONS: Crude enzyme extract of the fungus D. flagrans destroyed the L1 in vitro and can be used as a biological control for this nematode.
