Microbiol."],"abstract":"<jats:p>The white-backed planthopper (WBPH, <jats:italic>Sogatella furcifera<\/jats:italic>) is a notorious pest affecting rice production in many Asian countries. <jats:italic>Beauveria bassiana<\/jats:italic>, as the most extensively studied and applied insect pathogenic fungus, is a type of green and safe biological control fungus compared to chemical insecticides, and it does not pose the \u201c3R\u201d problem. In this study, the strain BEdy1, which had better pathogenicity to WBPH, was screened out from eight strains of <jats:italic>B. bassiana<\/jats:italic>. The daily growth rate, sporulation, and germination rate of BEdy1 strain were 3.74\u2009mm\/d, 1.37\u2009\u00d7\u200910<jats:sup>8<\/jats:sup> spores\/cm<jats:sup>2<\/jats:sup>, and 96.00%, respectively, which were significantly better than those of other strains. At a concentration of 1\u2009\u00d7\u200910<jats:sup>8<\/jats:sup> spores\/mL, the BEdy1 strain exhibited the smallest LT<jats:sub>50<\/jats:sub> value (5.12 d) against the WBPH, and it caused the highest cumulative mortality and muscardine cadaver rates of the pest, which were 77.67 and 57.78%, respectively. Additionally, BEdy1 exhibited a significant time-dose effect on WBPH. This study further investigated the pathogenic process of BEdy1. The results showed that BEdy1 invaded by penetrating the body wall of the WBPH, with its spores mostly distributed in the insect\u2019s abdominal gland pores, compound eyes on the head, and other locations. At 36\u2009h, the germinated hyphae penetrated the insect\u2019s body wall and entered the body cavity. At 84\u2009h, the hyphae emerged from the body wall and accumulated in the insect\u2019s abdomen, leading to a significant number of insect deaths at this stage. At 120\u2009h, the hyphae entangled the insect\u2019s compound eyes and produced new conidia on the insect\u2019s body wall, entering a new cycle of infection. These findings indicate that BEdy1 has a strong infection ability against WBPH. In summary, this study provides a new highly pathogenic strain of <jats:italic>B. bassiana<\/jats:italic>, BEdy1, for the biological control of WBPH, which is of great significance for the green prevention and control of rice pests.<\/jats:p>","DOI":"10.3389\/fmicb.2024.1469255","type":"journal-article","created":{"date-parts":[[2024,11,25]],"date-time":"2024-11-25T06:24:18Z","timestamp":1732515858000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Screening of the highly pathogenic Beauveria bassiana BEdy1 against Sogatella furcifera and exploration of its infection mode"],"prefix":"10.3389","volume":"15","author":[{"given":"Xing","family":"Xiang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siyuan","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrews Danso","family":"Ofori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuhua","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qunfang","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Shang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,11,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"47","DOI":"10.1016\/j.pestbp.2019.04.008","article-title":"Cross-resistance and biochemical characterization of buprofezin resistance in the white-backed planthopper, Sogatella furcifera (Horvath)","volume":"158","author":"Ali","year":"2019","journal-title":"Pestic.
