2,4‐dihydroxy‐7‐methoxy‐1,4‐benzoxazin‐3‐one (DIMBOA), the main benzoxazinoid found in corn, elicits variable larval responses from different pest moths. For the widespread and highly polyphagous Spodoptera frugiperda (Lepidoptera: Noctuidae), the fall‐armyworm (FAW), DIMBOA acts as a feeding stimulant and improves larval growth at low concentrations. The FAW present two host plant‐related strains, corn and rice strains, related to host preference on corn and other Graminae or rice. Based on both host preference and strain divergence of the FAW on corn, a cereal containing DIMBOA, and rice, lacking this compound, we question if corn and rice strains larvae respond equally toward DIMBOA. We evaluated differential expression in the transcriptome of both midgut and fat body larval tissues of the two strains reared on either DIMBOA‐enriched artificial diet or control diet and inferred Bayesian networks.

转录组差异共表达揭示了秋季粘虫菌株对DIMBOA的独特分子反应。

2,4-二羟基-7-甲氧基-1,4-苯并恶嗪-3-酮（DIMBOA）是玉米中发现的主要苯并恶嗪类化合物，可引起不同害虫蛾产生不同的幼虫反应。对于分布广泛且高度多食的夜蛾（Spodoptera frugiperda）（鳞翅目：夜蛾科），秋虫（FAW），DIMBOA可以作为饲料的刺激物，并在低浓度下改善幼虫的生长。一汽提出了两种与寄主植物有关的菌株，即玉米和水稻，与寄主对玉米和其他禾本科或水稻的偏好有关。基于宿主的偏爱和一汽对缺乏这种化合物的谷物（玉米中含有DIMBOA的谷物）和水稻的菌株差异，我们质疑玉米和水稻菌株的幼虫对DIMBOA的反应是否均等。我们评估了在富含DIMBOA的人工饮食或对照饮食和推断的贝叶斯网络下饲养的两个菌株的中肠和脂肪幼虫组织的转录组中的差异表达。
