Studies were carried out to determine if susceptibility of the cereal aphid Metopolophium dirhodum to the fungus Pandora neoaphidis was affected by wheat expressing snowdrop lectin (GNA). Aphid infection did not differ significantly between the transgenic GNA and non-transformed lines (91 and 82%, respectively). Fecundity also did not differ between aphids on the two lines, and was ca. 18 nymphs adult(-1). Time to infection was ca. 5 days for M. dirhodum on both lines in two of three assays. Our results indicate that wheat expressing GNA would not compromise the efficacy of P. neoaphidis as a biocontrol agent.
开展了多项研究，以确定谷物蚜虫麦二叉蚜对真菌新蚜虫疠霉的易感性是否会受到表达雪花莲凝集素（GNA）的小麦的影响。转基因GNA品系和非转基因品系之间的蚜虫感染率没有显著差异（分别为91%和82%）。两种品系上的蚜虫繁殖力也没有差异，约为每头成虫产18头若虫。在三项试验中的两项试验里，麦二叉蚜在两种品系上的感染时间均约为5天。我们的结果表明，表达GNA的小麦不会损害新蚜虫疠霉作为生物防治剂的功效。
