The objective of this study was to evaluate whether there are potential biocontrol candidates within the <\/span><span class=\"fontstyle1\">E<\/span><span class=\"fontstyle3\">. <\/span><span class=\"fontstyle1\">tortuosalis <\/span><span class=\"fontstyle3\">population. Sixteen bacterial strains were isolated from <\/span><span class=\"fontstyle1\">E. tortuosalis <\/span><span class=\"fontstyle3\">larvae that were parasitized in a <\/span><span class=\"fontstyle1\">C<\/span><span class=\"fontstyle3\">. <\/span><span class=\"fontstyle1\">tabularis <\/span><span class=\"fontstyle3\">plantattion in Nghe An province. Four isolates (FPRC06, FPRC07, FPRC14 and FPRC16) had strongest pathogenicity on <\/span><span class=\"fontstyle1\">Galleria mellonella <\/span><span class=\"fontstyle3\">larvae at 1, 24 and 36 hours after the injection and 72, 96 and 120 hours after the spraying experiments. The mortality rate of <\/span><span class=\"fontstyle1\">G. mellonella <\/span><span class=\"fontstyle3\">resulted from these two experimental approaches at the end of experiments was 93.3\u2013100% and 76.7\u2013100%, respectively. In a greenhouse experiment, the four isolates caused 44.3\u201361.1%, 52.0\u201368.0%, 54.3\u201369.1% and 41.4\u201360.7% mortality of <\/span><span class=\"fontstyle1\">E. tortuosalis <\/span><span class=\"fontstyle3\">larvae after 3, 5 and 7 days of spraying, respectively. These results were similar to applying a commercial <\/span><span class=\"fontstyle1\">Bacillus thuringiensis<\/span><span class=\"fontstyle3\">. The two isolates (FPRC07, FPRC14) were identified as <\/span><span class=\"fontstyle1\">Serratia marcescens <\/span><span class=\"fontstyle3\">based on phylogenetic analysis of 16S rRNA. Thus, this finding reveals the potential opportunities for the development of a natural insecticide of <\/span><span class=\"fontstyle1\">E. tortuosalis <\/span><span class=\"fontstyle3\">in Vietnam.<\/span> <\/p>\n<p><a href=\"https:\/\/doi.org\/10.55250\/jo.vnuf.2023.15.100-107\">https:\/\/doi.org\/10.55250\/jo.vnuf.2023.15.100-107<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pham Duy Long, Le Bao Thanh, Tran Xuan Hung, Hoang Thi Hang, Dinh Tien Tai, Phuong Van Phuc, Bui Duc Long, Nguyen Minh Chi.
