Ants are key species in Mediterranean pear orchards due to the mutualistic relationship they establish with honeydew-producing hemipterans and its impact on other natural enemies, such as spiders and predatory mirids. The aim of this work was to assess intraguild interactions among the main predators in pear orchards, since such interactions may affect pest suppression. The interactions among the ant <em>Lasius grandis</em>, the myrmecomorphic mirid <em>Pilophorus gallicus</em> and two species of spiders (<em>Oxyopes lineatus</em> and <em>Philodromus lividus</em>) was assessed in the presence/absence of each species in a complete factorial design. The arena consisted of a 2-liter clear plastic jar with a pear seedling. Ant nests were connected to the arena by means of a plastic tube. The survival of <em>P. gallicus</em> was significantly reduced by ants and spiders<em>.</em> In addition, the survival of both spiders was significantly affected by <em>L. grandis</em>, with <em>O. lineatus</em> being more adversely affected than <em>P. lividus</em>. In arenas with ants, the addition of the spider <em>O. lineatus</em> further decreased <em>P. gallicus</em> survival, whereas when <em>P. lividus</em> was incorporated to the arena the survival of the mirid increased significantly. These findings corroborate that <em>L. grandis</em> is the top predator in Mediterranean pear orchards and that the role of other predators in pest regulation in this agroecosystem is expected to be conditioned by their interactions with ants.</div></div>","PeriodicalId":8880,"journal":{"name":"Biological Control","volume":"209 ","pages":"Article 105863"},"PeriodicalIF":3.4,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144827812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant pathogens and insects, even those with broad host ranges, exhibit some degree of phylogenetic conservatism in their host plant associations. Thorough host specificity testing is crucial to minimise the risk of off-target damage to native and economically important plant species. Host test lists need to be developed from an understanding of evolutionary relationships, usually visualised as a phylogenetic tree, together with plant functional traits, and geospatial information. Currently, the process of obtaining a host test list is not standardised, and the manual steps are time-consuming and challenging. We introduce a user-friendly, open-source visualisation tool called PhyloControl to aid researchers in biocontrol risk analysis. PhyloControl integrates taxonomic data, molecular data, spatial data, and plant traits in an intuitive interactive interface, empowering biocontrol practitioners to summarise, visualise and analyse data efficiently. Comprehensively sampled phylogenetic trees are often unavailable, and older published phylogenies often lack branch resolution and support, which increases uncertainty. PhyloControl includes a workflow implemented through Quarto notebooks in R that allows users to perform phylogenetic analyses on GenBank DNA sequences. The modular workflow also incorporates species distribution modelling to predict the current and potential extent of target weed species. PhyloControl will streamline the development of biocontrol host tests lists to support risk analysis and decision making in classical weed biological control.</div></div>","PeriodicalId":8880,"journal":{"name":"Biological Control","volume":"209 ","pages":"Article 105859"},"PeriodicalIF":3.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144771247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
