Eighteen flocks of European starlings (<i>Sturnus vulgaris</i>) foraged on sweet corn for several days in control and laser treated plots with ripe sweet corn while data were collected on where birds were distributed and how long birds foraged on corn. In 16 trials, fresh ears were presented on wooden sticks, and in two trials birds foraged on natural corn grown from seed. Birds were sexed and boldness scores were obtained. We predicted that (a) birds would avoid foraging on ears in laser plots and (b) if they did feed, lasers would reduce foraging bout duration.","PeriodicalId":218,"journal":{"name":"Pest Management Science","volume":"40 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142967873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, genome analysis indicated the presence of many undiscovered secondary metabolites in <jats:italic>S. tanashiensis</jats:italic> BYF‐112.RESULTSHerein, 12 new alkaloids, tianwuine A–E (1–5), cephalandole C (6), venezuelines I–L (7–10), <jats:italic>N</jats:italic>‐(4‐methylphenyl‐2‐hydroxy) formamide (11) and <jats:italic>N</jats:italic>‐(5‐formyl‐2‐hydroxyphenyl) formamide (12), as well as three known metabolites (13–15) were discovered from BYF‐112 based on a combination of genome mining and the one strain many compounds (OSMAC) strategy. Plausible biosynthetic pathways of 1–13 were proposed using bioinformatic analysis of the full genome of BYF‐112. Partial metabolites were evaluated <jats:italic>in vitro</jats:italic> for their antibacterial, phytotoxic, and anti‐inflammatory activities. Pyrroloformamide A (14) showed strong antibacterial activities against <jats:italic>Staphylococcus aureus</jats:italic>, methicillin‐resistant <jats:italic>Staphylococcus aureus</jats:italic>, <jats:italic>Pseudomonas syringae</jats:italic> pv. <jats:italic>actinidae</jats:italic>, <jats:italic>Xanthomonas oryzae</jats:italic> pv. <jats:italic>oryzae</jats:italic> and <jats:italic>Xanthomonas oryzae</jats:italic> pv. <jats:italic>oryzicola</jats:italic> at a concentration of 50 μg per 6 mm disk. Simultaneously, pyrroloformamide A (14) also had a strong inhibitory effect on the radicle growth of <jats:italic>Echinochloa crusgalli</jats:italic> with an inhibition rate of 98.01% at a concentration of 100 μg/mL, equivalent to the positive 2,4‐dichlorophenoxyacetic acid. Subsequently, the possible herbicidal mechanism of 14 was explored using molecular docking simulation.
