Effective early detection, monitoring and management methods are critical for reducing the impacts of insect pests in agriculture and forestry. Combining host plant volatiles with sex pheromones could enhance trapping methodologies, whilst the use of non-host volatiles could improve the effectiveness of pest management through repellency effects. In this meta-analysis approach, we analysed 51 studies that used electroantennograms (EAG), wind tunnels and/or field traps to evaluate the antennal and behavioural responses of Lepidoptera to sex pheromones combined with attractant or repellent plant volatiles. Proposed attractant plant volatiles had a positive association with female Lepidoptera responses to sex pheromone, but effects on males were highly variable, with unexpected repellency reported in some studies. Proposed repellent plant volatiles were significantly or near-significantly negatively associated with male attraction to sex pheromones but were scarcely studied. Sub-group analysis identified that male responses to sex pheromone were reduced when the dose of attractant plant volatile relative to sex pheromone was increased. Green-leaf volatiles were associated with the strongest positive effects for males in field traps. Multiple-compound attractant plant volatile blends were less effective than single compounds in field studies. Our analysis demonstrates, (i) the potential value of combining host plant volatiles with sex pheromones to capture females rather than only males, (ii) the importance of identifying appropriate host plant volatiles and optimal relative doses, and (iii) the potential for non-host plant volatile use in pest management strategies.

对植物挥发物和性信息素增强鳞翅目害虫检测和管理潜力的荟萃分析研究

有效的早期发现、监测和管理方法对于减少害虫对农业和林业的影响至关重要。将寄主植物挥发物与性信息素相结合可以增强诱捕方法，而使用非寄主挥发物可以通过驱避作用提高害虫管理的有效性。在这种荟萃分析方法中，我们分析了 51 项研究，这些研究使用触角电图 (EAG)、风洞和/或场陷阱来评估鳞翅目对性信息素与引诱或驱避植物挥发物的触角和行为反应。所提出的引诱植物挥发物与雌性鳞翅目对性信息素的反应呈正相关，但对雄性的影响变化很大，一些研究报告了意想不到的排斥性。所提出的驱虫植物挥发物与雄性对性信息素的吸引力显着或接近显着负相关，但很少进行研究。亚组分析发现，当引诱植物挥发物相对于性信息素的剂量增加时，雄性对性信息素的反应会降低。绿叶挥发物对田间诱捕器中的雄性具有最强的积极作用。在实地研究中，多种化合物引诱植物挥发性混合物的效果不如单一化合物。我们的分析表明，（i）将寄主植物挥发物与性信息素结合起来捕获雌性而不仅仅是雄性的潜在价值，（ii）确定适当的寄主植物挥发物和最佳相对剂量的重要性，以及（iii）非- 宿主植物挥发性物质在害虫管理策略中的应用。
