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. 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 fungi isolated from a cave in the Brazilian Cerrado against the . . The isolates were identified based on morphological features and ITS rDNA sequences. Fifteen filtrates of 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 (1), (1), (1), (1), (1), (1), (1), (1), (1), (1), (1), (3), and (1). The results showed 93.33% (14) of the fungal filtrates induced significant mortality, indicating their molluscicidal activity, with FCCUFG 100 and FCCUFG 107 causing 100% mortality in all dilutions. These results reveal the potential of fungi from a Brazilian Cerrado cave as a promising approach for snail control.
真菌通过寄生、共生和互利共生在生态系统中发挥着至关重要的作用。此外，它们作为生物活性化合物生产者和生物防治剂在工业中被广泛使用。扁卷螺是一种淡水蜗牛，通常使用化学杀螺剂进行防治。然而，开发这些化学处理方法的有效替代方法至关重要。本研究评估了从巴西塞拉多一个洞穴中分离出的真菌的培养上清液对扁卷螺的杀螺潜力。根据形态特征和ITS rDNA序列对分离株进行了鉴定。获得了15种真菌的滤液，并在96小时的暴露期间对新孵化的蜗牛进行了纯滤液和不同稀释度（10%和50%）的测试。这些真菌分离株被鉴定为属于曲霉属（1种）、青霉属（1种）、镰刀菌属（1种）、毛壳菌属（1种）、木霉属（1种）、链格孢属（1种）、枝孢属（1种）、拟青霉属（1种）、头孢霉属（1种）、球毛壳属（1种）、刺盘孢属（1种）、轮枝孢属（1种）、根霉属（3种）和毛霉属（1种）。结果显示，93.33%（14种）的真菌滤液诱导了显著的死亡率，表明它们具有杀螺活性，其中FCCUFG 100和FCCUFG 107在所有稀释度下均导致100%的死亡率。这些结果揭示了来自巴西塞拉多洞穴的真菌作为一种有前途的蜗牛防治方法的潜力。
