Atividade larvicida do extrato bruto enzimático do fungo Duddingtonia flagras sobre larvas de primeiro estádio de 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.
