摘要

Wang, K.-H. and C. R. R. Hooks. 2009. Plant-parasitic nematodes and their associated natural enemies within banana (Musa spp.) plantings in Hawaii. Nematropica 39:57-73. A survey of banana fields was conducted on the Hawaiian islands of Kauai, Oahu, Maui, Lanai, Molokai and Hawaii in 2007 and 2008 to determine the most important plant-parasitic nematodes and their natural enemies associated with banana plantings in Hawaii. Plant-parasitic nematodes were surveyed from soil and banana root tissues collected at twenty seven banana farms among the Hawaiian islands. Meloidogyne spp., Helicotylenchus sp., followed by Rotylenchulus reniformis were the most frequently found plant-parasitic nematodes through soil assay. However, the bacterium Pasteuria penetrans, an obligate parasite of nematodes, was found attached to the cuticle of Meloidogyne juveniles at 26% of the sites surveyed. Root assay revealed that Helicotylenchus multicinctus reached higher abundance in banana root tissues compared to Meloidogyne sp., R. reniformis, R. similis and Pratylenchus sp. Elevated counts of Pratylenchus sp. and R. similis were only recorded from banana roots at one and two farm sites, respectively. Thus, H. multicinctus which was not considered an important plant-parasitic nematode in the past with respect to Hawaii banana fields should receive greater attention. Finally, the survey confirmed our assumption that potential natural enemies of plant-parasitic nematodes, including omnivorous and predatory nematodes, nematode-trapping fungi and P. penetrans, are commonly found. Any management practices developed to manage nematode problems in Hawaiian banana fields should be cautious of any ill effects on beneficial soil organisms.

Hooks。 2009年。夏威夷香蕉（Musa spp。）种植中的植物寄生线虫及其相关的天敌。 Nematropica 39：57-73。 2007年和2008年，在夏威夷的考艾岛，瓦胡岛，毛伊岛，拉奈岛，莫洛凯岛和夏威夷群岛上进行了香蕉田调查，以确定最重要的植物寄生线虫及其与夏威夷香蕉种植相关的天敌。从在夏威夷群岛中的27个香蕉农场收集的土壤和香蕉根组织中调查了植物寄生线虫。根结线虫属种，Helicotylenchus sp。，其次是轮状轮虫，是通过土壤测定法最常发现的植物寄生线虫。然而，在26％的被调查地点发现，巴斯德氏菌（Pasteuria penetrans）是一种线虫的专性寄生虫，附着在幼虫的表皮上。根试验表明，与Meloidogyne sp。，R。reniformis，R。similis和Pratylenchus sp。相比，多螺旋螺旋藻在香蕉根组织中的丰度更高。 Pratylenchus sp。的高架计数。和R. similis分别仅在一个和两个农场地点的香蕉根中记录到。因此，在夏威夷香蕉田上过去不被认为是重要的植物寄生线虫的多刺线虫应引起更大的关注。最后，调查证实了我们的假设，即通常会发现植物寄生线虫的潜在天敌，包括杂食性和掠食性线虫，捕获线虫的真菌和P. penetrans。为处理夏威夷香蕉田中的线虫问题而开发的任何管理措施都应谨慎对待对有益土壤生物的不良影响。
