| To study the structural diversity of the endobiotic yeast isolated from Locusta migratoria manilensis
and Ischiodon scutellaris Fabricius and compare diversity of endobiotic yeasts isolated from insdects with differenet
ecologic functions inagriculture ecosystem, we sequenced 26SrDNA of endobiotic yeast from two samples by Illumina
Miseq high-throughput sequencing method, and classified operational taxonomic unit and analysed the Alpha diversity
by Mouthor software. And then，we analysed the signifiance of diversity difference by SPSS, a total of 906 OTU were
detected, 647 OTU from Locusta migratoria migratoria and 677 OTU from Ischiodon scutellaris Fabricius. among
which 418 OTU are shared in two samples. Yeasts were identified and classified into 2 plylums and 19 genus in the
two samples. The biodiversity of endobiotic yeas in Locusta migratoria migratoria is little more than that in Ischiodon
scutellaris Fabricius. Meanwhile, we identified biological control yeasts belongs to Sporobolomyces and Cyberlindnera
only in Locusta migratoria migratoria The endobiotic yeasts isolated from Locusta migratoria migratoria and
Ischiodon scutellaris Fabricius in Xinjiang are abundant and various. The micro-environment they existed is special.
It could provide new ideas for pest control and yeasts resoueses utilization in special environment. |
