Blackcurrant leaf midge () is a widespread pest of blackcurrant. Attacks by this pest can cause up to 60% reduction in the growth of shoots resulting in yield decreases. Our study, conducted (2012-2014) in Poland, aimed to assess the susceptibility of blackcurrant genotypes to , in order to select genotypes as parental lines for breeding new blackcurrant genotypes. Among tested blackcurrant genotypes, none were found to be completely resistant to this pest. The pest colonized genotypes Big Ben, Nr 8/72, Ben Connan, Ben Alder, Ben Hope, Foxendown, Ben Nevis, Fariegh, Ojebyn, and Ben Tirran below the threshold level (10%). In contrast, genotypes Nr 7/15, Ben Lomond, Ben Finlay, Tisel, Polares, Polonus, Tiben, PC-110, Polben, Gofert, Ruben, and Ores suffered pest levels above the threshold. With regard to egg numbers, the fewest were recorded on genotypes Big Ben, Ben Connan, Ben Alder, and Ben Nevis, and the most on Gofert and Ores. Fewer larvae were recorded on genotypes Big Ben, Nr 8/72, Ben Connan, and Foxendown compared to Ben Lomond, PC-110, Gofert, Tiben, Polben, and Ores. Developing blackcurrant genotype resistance to leaf midge strongly supports the IPM strategy.
黑醋栗叶瘿蚊是黑醋栗中广泛存在的一种害虫。这种害虫的侵袭可导致新梢生长量减少多达60%，从而造成产量下降。我们于2012 - 2014年在波兰开展的研究旨在评估黑醋栗基因型对黑醋栗叶瘿蚊的易感性，以便选择基因型作为培育新黑醋栗基因型的亲本系。在测试的黑醋栗基因型中，未发现有对这种害虫完全抗性的。该害虫在低于阈值水平（10%）的情况下侵害了基因型为大本钟、Nr 8/72、本·康南、本·阿尔德、本·霍普、福克斯唐、本·尼维斯、法里厄、奥耶宾和本·蒂兰的植株。相比之下，基因型为Nr 7/15、本·洛蒙德、本·芬利、蒂塞尔、极地、波兰人、蒂本、PC - 110、波兰本、戈费特、鲁本和奥雷斯的植株遭受的害虫侵害水平高于阈值。关于卵的数量，在基因型为大本钟、本·康南、本·阿尔德和本·尼维斯的植株上记录到的最少，而在戈费特和奥雷斯上记录到的最多。与本·洛蒙德、PC - 110、戈费特、蒂本、波兰本和奥雷斯相比，在基因型为大本钟、Nr 8/72、本·康南和福克斯唐的植株上记录到的幼虫较少。培育对叶瘿蚊具有抗性的黑醋栗基因型有力地支持了综合虫害管理策略。
