In a long-term study, the number of male and female flies was recorded in towns and surrounding orchards in Manjimup (1991–2022) and Pemberton (1996–2022). Implementation of whole orchard integrated pest management (IPM) strategies included the use of insecticide treatments based on action thresholds. The application of early season insecticide + protein spot bait treatments eliminated the need for pesticide cover sprays. Synchronisation of treatment times within the same week or fortnight across all orchards in each district improved Medfly control within an area-wide management (AWM) program. From the initial 1992 baseline of 12.04 flies/trap/day (FTD) in Manjimup town and 0.42 FTD in commercial orchards, numbers were reduced 4-fold in the town (2.82 FTD) and 18.5-fold (0.0230 FTD) in the orchards. In Pemberton town, the Medfly population was very low (&lt; 0.01 FTD) while in the surrounding orchards, high-density trapping detected only 29 adult Medfly over 27 years, with several years of zero numbers. A major contribution to the success of AWM in the two towns and surrounding orchards was the continuing awareness programs on Medfly control funded by industry, government, and town councils. These findings are valuable for designing AWM strategies for Medfly where growers and townspeople are motivated to cultivate pest-free produce for domestic consumption and market access.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"149 7","pages":"1129-1145"},"PeriodicalIF":1.7,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144606550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

European and national directives mostly focus on the monitoring of three taxa: bees (Hymenoptera: Apoidea: Anthophila), hoverflies (Diptera: Syrphidae) and lepidopterans (Lepidoptera). However, an effective prioritisation of taxa for pollinator research should consider their actual role as pollinators, which can vary according to the considered ecosystem. Moreover, knowledge about the specific potential of different taxa as pollinators in different ecosystems is still limited. Here, we evaluated, in mountain environments in the European Alps, the potential as pollinators of the three aforementioned taxa together with three other occurring flower-visiting taxa: beetles (Coleoptera), muscid flies (Diptera: Muscidae) and ants (Hymenoptera: Formicidae). We compared them in terms of flower visitor abundance and actual pollen transport. In addition, we evaluated whether the scientific efforts made thus far by European researchers aligned with the actual potential of the different taxa as pollinators in a mountain context. Bees and hoverflies have been found to be both the most effective pollen carriers and the most studied pollinators. Instead, a clear discrepancy is observed for muscid flies and lepidopterans, with the former being underrepresented in the scientific literature compared to their actual potential as pollinators, while the latter are overrepresented, ranking as the second most studied taxon despite being the least abundant visitors and contributing negligibly to pollen transport.

Conventional control approaches for managing this insect rely on pesticide applications, which pose environmental risks and can lead to pest resistance. Thus, the necessity for alternative management strategies is emphasised. Silicon (Si) is proposed as a pesticide substitute due to its ability to mitigate a plethora of biotic and abiotic stresses in plants. To evaluate the effectiveness of Si in controlling the armyworm, maize plants were treated with three Si concentrations (T1: 500 mg/L, T2: 750 mg/L, T3: 1000 mg/L) and then infested with armyworm larvae. The performance of the insect pest was assessed by evaluating its larval feeding and oviposition preference, mandibular morphology, survival rates and weight gain. Results showed a mean larval survival rate of 63% in T3 plants compared to 96% in control. The weight of larvae fed on control leaves was twice that of those fed on Si-treated leaves. Likewise, the incisor length of larvae fed on Si-treated leaves was significantly shorter (177 μm) than those fed on control leaves (447 μm). Moreover, Si-treated leaves were less favourable for egg laying, with only 20% of eggs laid on them. These findings indicate that Si supplementation enhances maize resistance to the infestation of the oriental armyworm. This Si-mediated resistance of maize plants against the oriental armyworm underscores the potential of Si supplementation as a sustainable alternative to chemical pesticides in integrated pest management strategies.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"149 7","pages":"1059-1069"},"PeriodicalIF":1.7,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144606520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
