摘要

在田间豇豆植株上检测到贝塞阿芬氏蜱(Aphelenchoides besseyi)是引起叶片黑斑病的病原菌，并证实了其致病性。利用针对28S rDNA的物种特异性引物Abess_11F/Abess_11R扩增了570 bp的片段，通过形态学、形态测量学和分子鉴定确定了线虫的身份。这是巴西首次在田间条件下报道贝赛伊蜂寄生豇豆。

Aphelenchoides besseyi causing leaf spot on cowpea under field conditions in Brazil

Aphelenchoides besseyi was detected as the causal agent of foliar dark spots on cowpea plants growing in the field, and its pathogenicity was confirmed. The identity of the nematode was determined through morphological, morphometric, and molecular characterization, using species-specific primers Abess_11F/Abess_11R targeting 28S rDNA, which amplified a fragment of 570 bp. This is the first report of A. besseyi parasitizing cowpea under field conditions in Brazil.
