| the characterization of microsporidian isolates (nosematidae: nosema) from five important lepidopteran pests in taiwan. | microsporidian isolates from five lepidopteran pests-spodoptera litura, spodoptera exigua, helicoverpa armigera, plutella xylostella, and pieris spp.-were compared by spore morphology, infectivity to s. litura, western-blot banding patterns, the sequences of small subunit rrna gene (ssurrna sequence), and random amplified polymorphic dna polymerase chain reaction (rapd-pcr). all the isolates could infect experimentally and multiply in the larvae of s. litura. the s. exigua isolate showed the hig ... | 2003 | 12725812 |
| phylogenetic analysis of two putative nosema isolates from cruciferous lepidopteran pests in taiwan. | in this study, a new microsporidian, px2, was isolated from the diamondback moth, plutella xylostella, and then compared with another isolate (px1), and with nosema spodopterae and n. bombycis. sequence data showed that the rrna gene organizations of px1 and px2 exhibited a typical nosema-specific organization: 5'-lsurrna (large subunit ribosomal rna)-its (internal transcribed spacer)-ssurrna-igs (intergenic spacer)-5s-3'. phylogenetic analysis (maximum likelihood, neighbor joining, maximum pars ... | 2007 | 17266983 |
