The most abundant aphid species in Mediterranean citrus are <em>Aphis gossypii</em> and <em>Aphis spiraecola</em>. Foliar applications of pesticides are commonly used with aphid management programs. However, these applications are usually carried out in a non-optimised way, using water volume rates that are higher than necessary. <em>CitrusVol</em> is a decision support tool that recommends an optimal volume rate adjusted to the vegetation characteristics, the pest, and the pesticide. It has been validated for other important citrus pests such as <em>Aonidiella aurantii</em> and <em>Tetranychus urticae</em> but not for aphids. In this work, the <em>Proof-CitrusVol</em> version was evaluated by comparing the aphid control efficacy of applications adjusted using the tool versus conventional higher-volume applications. Based on insufficient aphid control during the initial year of field testing, the tool was modified, and a new version was subsequently validated. The field trial results showed that <em>CitrusVol</em> reduced the spray volume by 29% on average without affecting control efficacy compared with conventional applications. Consequently, <em>CitrusVol</em> reduced the operational time by 16 h/100 ha per application because of fewer refills of the sprayer tank. This represents a savings in fuel consumption of 159 L/100 ha and CO₂ emissions reduction of 415 kg CO₂/100 ha per application. Accordingly, <em>CitrusVol</em> allows optimisation of spray applications against aphids in citrus, making them more profitable and environmentally sustainable than the conventional applications.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"194 ","pages":"Article 107187"},"PeriodicalIF":2.5,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705581","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}

While the adaptability of Asian corn borer (<em>Ostrinia furnacalis</em>) (Lepidoptera: Crambidae) is well-documented, the extent to which different populations diverge in fitness when reared on natural versus artificial diets remains poorly understood. This study addresses this gap by assessing the fitness and adaptive divergence of three <em>O. furnacalis</em> populations i.e., field, laboratory, and hybrid (field × laboratory), when reared on maize and artificial diets, using age-stage, two-sex life table theory. Significant differences in survival and demographic parameters were observed among the populations. The field population exhibited 32.5 % faster growth on maize, with a shorter mean generation time (<em>T</em>) compared to the artificial diet. In contrast, the laboratory population grew (<em>T</em>) 29.5 % faster on the artificial diet compared to maize. The hybrid population showed a slight preference for maize, with growth (<em>T</em>) being 3.1 % faster than on the artificial diet. Trends in intrinsic rate of increase (<em>r</em>), finite rate of increase (<em>λ</em>) and other associated parameters followed a consistent pattern, with field population thriving on maize and laboratory population better suited to the artificial diet. The hybrid population demonstrated balanced adaptability to both diets, with an overall slight tendency of better performing on maize.
