Abstract

The aim of the present test was to develop a Pasteuria penetrans isolate (Pp3) on a Meloidogyne blend and compare the attachment and pathogenic potential of this heterogeneously produced isolate with other Pp3 isolates produced on individual Meloidogyne species (Meloidogyne javanica, M. incognita and M. arenaria). Number of spores attached varied among Meloidogyne spp. Pp3 isolate originally multiplied on M. javanica showed greater attachment level with second stage juveniles (J2s) of M. javanica (13.8) than other Meloidogyne spp. tested and lesser attachment was observed on J2s of a M. arenaria. The Pp3 isolate showed variable influence on the Meloidogyne spp. in suppressing root-knot disease. There was a significant difference in numbers of eggmasses produced by females of Meloidogyne spp. Higher numbers of eggmasses were recorded with females of M. arenaria (370) while fewer numbers of eggmasses were observed in treatment where M. javanica (245) was present. Root galling differed significantly among treatments (P0.01) and higher gall infestation was recorded in M. arenaria treatment (6.2) while lesser galling was observed in M. javanica treatment (4.4). Final female population also varied among treatments (P0.05) showing higher numbers of females in M. arenaria treatment (456) and fewer with M. javanica (398). Parasitism of females of Meloidogyne spp. by Pp3 differed significantly among treatments. Higher numbers of females infected with Pp3 spores were recorded among females of M. javanica (14.4) while lesser numbers of parasitized females were observed in M. arenaria treatment (9.8). There were significant variations in numbers of endospores/female produced by females of Meloidogyne spp. however egg set data did not differ in the treatments. The results showed that the Pp3 isolate was more pathogenic on M. javanica compared with other Meloidogyne spp. (M. incognita, M. arenaria and M blend). The Pp3 isolate was found compatible with different Meloidogyne spp. while M. arenaria proved the least good host to bacterial parasite

异种产透性巴氏菌(PP3)分离物在孢子附着上对巴氏菌个体的影响及对三种长尾线虫致病潜力的研究

本试验的目的是在一种Meloidogyne混合物上培养出一种渗透巴氏菌分离物(Pp3)，并将这种异质生产的分离物与在单个Meloidogyne物种(javanica Meloidogyne, M. incognita和M. arenaria)上生产的其他Pp3分离物的附着性和致病潜力进行比较。不同芽孢的附着孢子数存在差异，Pp3原株与爪哇绿僵菌2期幼虫的附着水平(13.8)高于其他菌株，而与沙棘绿僵菌2期幼虫的附着程度较低。Pp3分离物对Meloidogyne菌株抑制根结病表现出不同程度的影响。两种处理的卵数差异有统计学意义，其中沙棘棘球蚴(370粒)的卵数较多，爪牙棘球蚴(245粒)的卵数较少。不同处理间根瘤率差异极显著(P0.01)，沙棘组根瘤率较高(6.2)，土芹组根瘤率较低(4.4)。最终雌虫种群数量在不同处理间也存在差异(P0.05)，沙粒稻组雌虫数量较多(456只)，爪牙稻组雌虫数量较少(398只)。各处理间雌虫对Pp3的寄生率差异显著。染Pp3孢子的雌虫数量较多(14.4)，而染Pp3孢子的雌虫数量较少(9.8)。在不同处理下，母株产生的内生孢子/雌株数有显著差异，但卵数无显著差异。结果表明，Pp3分离物对javanica的致病性高于其他Meloidogyne属(M. incognita、M. arenaria和M. blend)。Pp3分离物与不同的Meloidogyne属均有亲和性，而M. arenaria是最不适合细菌寄生的宿主
