摘要

The diversity and community structure of nematodes associated with banana plantations in the Muzaffarpur district were investigated in this study. A total of 16 nematode genera were identified and classified into plant parasitic nematodes (PPN), predatory nematodes (PRN), and microbivorus nematodes (MVN). Among the PPN, Radopholus similis and Pratylenchus coffeae were the most frequent (43.7% and 43.5%, respectively). P. coffeae also exhibited the highest density (5.6) and prominence value (0.4). In the PRN group, Mylonchulus sp. was the most frequent (37.5%) and had the highest prominence value (0.2), while Dorylaimus sp. showed the highest biomass (51.731 µg). Chiloplacus sp. dominated in the MVN group with the highest frequency (43.7%), density (8.4), and prominence value (0.6). Importance value analysis underscored Dorylaimus sp. as the most significant nematode in the community, followed by Chiloplacus sp. and H. indicus. The trophic group-wise analysis highlighted PPN group as the most prevalent in terms of frequency and density, whereas PRN group exhibited the highest biomass. These findings provide a comprehensive understanding of nematode community dynamics in banana plantations, offering insights crucial for developing sustainable nematode management strategies to enhance banana crop health and productivity in Muzaffarpur district.
