The aim of this study was to select virulent strains of microfungi against Leucoagaricus gongylophorus, a symbiotic fungus cultivated by leaf-cutting ants. The results from in vitro assays showed that microfungal strains had a variable and significant impact on the colony development of L. gongylophorus. Specifically, Trichoderma harzianum, Escovopsis weberi CBS 810.71 and E. weberi A088 were more effective, inhibiting the L. gongylophorus colonies by 75, 68 and 67%, respectively (P < 0.05) after 15 days. Strain E. weberi A086 and Acremonium kiliense were less effective: 43 and 26%, respectively (P < 0.05). In spite of the current negative perspective of a microbiological control approach for these ants, the present work discusses the possibility of using mycopathogenic fungi for the control of these insects, and points out the importance of encouraging more studies in this area.
本研究的目的是筛选出对切叶蚁所培育的共生真菌——柱状白环蘑具有毒性的微真菌菌株。体外试验结果表明，微真菌菌株对柱状白环蘑菌落的发育具有不同程度的显著影响。具体而言，哈茨木霉、韦氏埃斯科菌CBS 810.71和韦氏埃斯科菌A088的效果更佳，15天后分别抑制了75%、68%和67%的柱状白环蘑菌落生长（P < 0.05）。韦氏埃斯科菌A086菌株和基利枝顶孢的效果较差，分别为43%和26%（P < 0.05）。尽管目前对于针对这些蚂蚁的微生物控制方法持负面看法，但本研究探讨了使用致病性真菌来控制这些昆虫的可能性，并指出了鼓励在该领域开展更多研究的重要性。
