Description
Summary:Fungi play vital roles in ecosystems through parasitism, commensalism, and mutualism. Additionally, they are widely used in industry as bioactive compound producers and biological control agents. <i>Biomphalaria glabrata</i> is a freshwater snail often controlled with chemical molluscicides. However, developing effective alternatives to these chemical treatments is essential. This study evaluated the molluscicidal potential of culture supernatant from <i>Hypocreales</i> fungi isolated from a cave in the Brazilian Cerrado against the <i>B</i>. <i>glabrata</i>. The isolates were identified based on morphological features and ITS rDNA sequences. Fifteen filtrates of <i>Hypocreales</i> fungi were obtained and tested both pure and in different dilutions (10% and 50%) against newly hatched snails during 96 h of exposure. The fungal isolates were identified as belonging to the genera of <i>Clonostachys</i> (1), <i>Cylindrocladiella</i> (1), <i>Fusarium</i> (1), <i>Gliocladiopsis</i> (1), <i>Keithomyces</i> (1), <i>Marquandomyces</i> (1), <i>Ovicillium</i> (1), <i>Pochonia</i> (1), <i>Purpureocillium</i> (1), <i>Sarcopodium</i> (1), <i>Sarocladium</i> (1), <i>Trichoderma</i> (3), and <i>Volutella</i> (1). The results showed 93.33% (14) of the fungal filtrates induced significant mortality, indicating their molluscicidal activity, with <i>Pochonia chlamydosporia</i> FCCUFG 100 and <i>Volutella aeria</i> FCCUFG 107 causing 100% mortality in all dilutions. These results reveal the potential of <i>Hypocreales</i> fungi from a Brazilian Cerrado cave as a promising approach for snail control.
