Crop enhancement with value added traits may affect vulnerability to insects, and evaluating the susceptibility levels of the various value added traits in elite germplasm would aid in developing integrated pest management strategies. During 2007-2008, five 'Benning' soybean (Glycine max (L.) Merr) lines with different value added nutritional traits and four insect resistant quantitative trait loci (QTL) lines were evaluated in an effort to determine their pest vulnerability under artificial and natural insect pest populations. The lines showed variable susceptibility to lepidopterous insect pests classified as defoliators and stem feeders in replicated greenhouse and field tests. The study was carried out in Athens and Midville, GA. The green cloverworm (Hypena scabra (F.)) was the most common lepidopteran defoliator occurring in the fields. Other caterpillar pests found included the soybean looper (Pseudoplusia includens (Walker)), the bollworm (Helicoverpa zea (Boddie)), and the velvetbean caterpillar (Anticarsia gemmatalis (Hübner)). Data indicated that there was no significantly increased pest susceptibility among the value added cultivars with improved nutritional qualities, with the insect resistant quantitative trait loci lines Benning M and Benning MGH consistently being less susceptible to lepidopterous (Noctuidae) leaf injury.
具有增值特性的作物改良可能会影响对昆虫的易感性,评估优良种质中各种增值特性的易感性水平将有助于制定综合虫害管理策略。在 2007 年至 2008 年期间,对五个具有不同增值营养特性的“Benning”大豆(Glycine max (L.) Merr)品系和四个抗虫数量性状位点(QTL)品系进行了评估,以确定它们在人工和自然虫害种群下的虫害易感性。这些品系在重复的温室和田间试验中表现出对鳞翅目害虫(分类为食叶害虫和蛀茎害虫)的不同易感性。该研究在佐治亚州的雅典和米德维尔进行。绿芫菁(Hypena scabra (F.))是田间最常见的鳞翅目食叶害虫。其他发现的毛毛虫害虫包括大豆夜蛾(Pseudoplusia includens (Walker))、棉铃虫(Helicoverpa zea (Boddie))和银纹夜蛾(Anticarsia gemmatalis (Hübner))。数据表明,在具有改善营养品质的增值品种中,没有明显增加的害虫易感性,抗虫数量性状位点品系 Benning M 和 Benning MGH 始终对鳞翅目(夜蛾科)叶片损伤的易感性较低。
