Abstract

The identification of phytoparasitic nematodes, which is essential for the implementation of management strategies, is required for further study. The objective of this work was to identify, at the genus level, the phytoparasites and free-living nematodes associated with the cultivation of sweet granadilla (Passiflora ligularis Juss.) in the valley of Sandia, region Puno, Peru. For the study, 165 soil samples were evaluated, coming from eight communities from the district of Sandia, during the agricultural season 2018–2019. The samples were processed by the method of centrifugal fluctuation in sucrose solution, later identified on the basis of morphological characteristics. The results showed the presence of seven genera of phytoparasitic nematodes, Meloidogyne, Pratylenchus, Helicotylenchus, Mesocriconema, Xiphinema, Tylenchus, and Hemicycliophora, and two genera of free-living nematodes, Aphelenchus and Dorylaimus. The most harmful genera were Meloidogyne and Pratylenchus because they cause damage to other crops. In the nematode community, there was variability in the density and frequency of phytoparasitic and free-living nematodes in the evaluated localities.

与秘鲁普诺地区桑迪亚山谷种植西番莲有关的植生寄生虫和自由生活的线虫

植物寄生线虫的鉴定对实施管理策略至关重要，需要进一步研究。这项工作的目的是鉴定与秘鲁普诺地区桑迪亚山谷甜格拉纳多拉（Passiflora ligularis Juss.）种植相关的植物寄生虫和自由生活线虫的属级。这项研究评估了 165 份土壤样本，这些样本来自桑迪亚区的 8 个社区，时间是 2018-2019 年农业季节。样本采用蔗糖溶液离心波动法进行处理，随后根据形态特征进行鉴定。结果表明存在 7 个植物寄生线虫属：Meloidogyne、Pratylenchus、Helicotylenchus、Mesocriconema、Xiphinema、Tylenchus 和 Hemicycliophora，以及 2 个自由生活线虫属：Aphelenchus 和 Dorylaimus。危害最大的属是 Meloidogyne 和 Pratylenchus，因为它们会对其他作物造成危害。在线虫群落中，被评估地区植物寄生线虫和自由生活线虫的密度和频率存在差异。

期刊介绍： Bioagro es una revista científica del Decanato de Agronomía de la Universidad Centroccidental “Lisandro Alvarado” (UCLA). Su periodicidad es cuatrimestral y se publica en los meses de enero, mayo y septiembre. Cada trabajo es revisado por al menos dos especialistas en el área, externos a la revista, de cuya opinión depende la aceptación definitiva. Se utiliza sistema de arbitraje doble ciego. La revista va dirigida, fundamental pero no exclusivamente, a profesionales y técnicos del área agrícola. Su objetivo es publicar trabajos científicos originales e inéditos en ciencias agrícolas que enfoquen aspectos de agronomía, botánica y propagación de plantas, entomología y zoología, suelos, fitopatología y protección vegetal, ingeniería agrícola, genética y mejoramiento de plantas, ecología, procesamiento de productos agrícolas, biotecnología y sociales. También pueden ser publicados artículos cortos en los que se presenten descubrimientos científicos, desarrollos tecnológicos y resultados de diagnósticos integrales, en la modalidad de Notas Técnicas. En Venezuela, se encuentra en las bibliotecas de todas las universidades e institutos de educación superior que ofrecen carreras agronómicas, así como de los entes oficiales de investigación agropecuaria. En el exterior, la revista llega a universidades y/o institutos de investigación agrícolas de todos los países de América Latina así como Estados Unidos, Canadá y España.
