Data for: Population genomic insights into invasion success in the polyphagous agricultural pest, Halyomorpha halys
<p>Invasive species are increasingly threatening ecosystems and agriculture by rapidly expanding their range and adapting to environmental and human-imposed selective pressures. The genomic mechanisms that underlie such rapid changes remain unclear, especially for agriculturally important pests. Here<span>,</span> we use genome-wide polymorphisms derived from native, invasive<span>,</span> and intercepted <span>samples and </span>populations of the brown marmorated stink bug (BMSB), <em>Halyomorpha</em> <em>halys</em>, to gain insights into population genomics processes that <span>have promoted</span> the successful global invasion of this polyphagous pest. Our analysis demonstrated that BMSB <span>exhibits spatial</span> structure but admixture rates are high among introduced populations, resulting in similar levels of genomic diversity across native and introduced populations. These spatial genomic patterns suggest a complex invasion scenario<span>, potentially</span> with multiple bridgehead events<span>, posing </span>a challenge for accurately assigning BMSB incursions to their source using reduced-representation genomic data. By associating allele frequencies with the invasion status of BMSB populations, we found significantly differentiated SNPs located in <span>close </span>proximity <span>to</span> genes for insecticide resistance and olfaction. <span>Comparing</span> variations in allele frequencies among populations for outlier SNPs suggests that BMSB invasion success has likely evolved from standing genetic variation. In addition to being a major nuisance of households, BMSB has caused significant economic losses to agriculture in recent years and continues to expand its range. Despite no record of BMSB insecticide resistance to date, our results show <span>high capacity for potential </span>evolution <span>of such characters</span>, highlighting the need for future sustainable and targeted management strategies.</p>

Effect of the localized insecticides spray technique to control Halyomorpha halys in Actinidia chinensis orchards.
<p><span>Kiwifruit production is rapidly expanding worldwide with China, New Zealand and Italy being the three major producing countries. <em>Halyomorpha halys</em>, the brown marmorated stink bug, is an invasive insect pest that in the last two decades has become a major problem for several agricultural commodities, including kiwifruit. Its management relies on integrating different control methods, including board-spectrum insecticides. Nevertheless, the chemical control may not achieve satisfactory results and there is still margin for improvement, considering for instance the optimization of the spray technique. This problem is even more relevant in kiwifruit due to its peculiar training system, which reduce fruit exposure to pesticide sprays. In this study, two spray techniques were tested to maximize the insecticides efficacy in controlling <em>H. halys</em> in both yellow- and green-flesh kiwifruit cultivars (‘Jintao’ and ‘Hayward’). The effects of a conventional ray atomizer and a trumpet-modified atomizer, which localizes insecticide applications in the fruit area, were assessed on <em>H. halys</em> mortality (with artificial infestations) and fruit damages (due to <em>H. halys</em><span> naturally occurring in the orchards</span>). The localized spray technique resulted in an overall significantly higher<em> H. halys</em> mortality in ‘Hayward’, but not in ‘Jintao’ cultivar. This is likely due to the differences in the canopy size and structure of these cultivars, observed recording biometric parameters of the vines. However, the fruit injury level was not different between the spray techniques. Further investigations in this direction are needed also to assess the efficiency of the localized spray technique in reducing insecticide dose and volume, in accordance to European strategies for sustainable developments that foreseen a restriction of authorized insecticidal active substances and an overall reduction of plant protection products usage.</span></p>
