Abstract

We examined the pattern of adherence of aquatic hyphomycetes conidia on six latex-coated slides (Artocarpus heterophyllus, A. hirsutus, Calotropis gigantea, Ficus benghalensis, Manilkara zapota and Plumeria rubra) with plain slides (control) exposed up to 18 h in a tropical coastal stream. Conidia of 21 species were trapped on latex-coated slides against seven on control slides. The total conidia adhered on latex-coated slides was higher than control slides. Latex-coated slides showed the highest diversity of aquatic hyphomycetes than control slides (1.805) and water (0.729). The top five species of aquatic hyphomycetes in latex-coated slides and drift conidia were comparable. Sørensen’s similarity of species in control slides against latex-coated slides ranged from 25% (P. rubra) to 62.5% (C. gigantea) indicating superiority of latex-coated slides in conidial trapping. Among the latex-coated slides, similarity varied between 13.3% (A. hirsutus vs. P. rubra) and 89.6% (F. benghalensis vs. M. zapota). One-way ANOVA showed significant difference in richness of species (P < 0.001) and conidia (P < 0.05) between control and latex-coated slides by F. benghalensis. Based on the trapping efficiency of species and conidia, the latex of F. benghalensis ranked first and serves as an inexpensive technique to monitor aquatic hyphomycetes in streams.
