摘要

Acanthoscelides obtectus (Coleoptera: Bruchidae) is one of the most important post-harvest pests of dry bean Phaseolus vulgaris Tepary bean (Phaseolus acutifolius) could be a novel source of resistance against A. obtectus to improve dry bean. We studied the resistance of tepary bean varieties to A. obtectus. We focused on three categories of defense: antixenosis, antibiosis, and tolerance. Tepary pinto amarillo (Tamarillo) and Tepary pinto negro (T-negro) beans show high antixenosis to adults, increased numbers paralyzed per hour and per day, and increased duration of development in winter; reduced oviposition, number of emerged adults and adult weight. Due to the small number of emerged adults, there was very little grain weight loss. Volatile compounds were discarded as the cause of paralysis in adults. Adults in Tamarillo and T-negro were paralyzed until day 10 and 14 and then, they die at an exponentially increasing rate. In addition T-negro and Tamarillo produced the highest mortality in larvae before entering the seeds. T-amarillo and T-negro showed antixenoxis, resistance and tolerance to A. obtectus infestation and they can be used as sources of resistance for P. vulgaris breeding. The compound that causes the antixenosis and paralysis in adults is in the testa of the resistant varieties and is not likely to be a volatile compound, whereas the mortality and antixenosis in larvae is caused more probably by a volatile compound present in the testa.

Detectus的抵抗力。我们专注于三类防御：抗屈曲，抗抗体和耐受性。 Tepary Pinto Amarillo（Tamarillo）和Tepary Pinto Negro（T-Negro）豆类向成年人显示出高抗屈曲，每小时瘫痪的数量增加，冬季的发展持续时间增加;减少产卵，出现的成年人数量和成人重量。由于出现的成年人数量少，粒度减肥很少。将挥发性化合物作为成人瘫痪的原因被弃出。 Tamarillo和T-Negro的成年人瘫痪至第10天和第14天，然后，他们以指数增加的速度死亡。此外，T-Negro和Tamarillo在进入种子之前在幼虫产生了最高的死亡率。 T-Amarillo和T-Negro显示抗尖端，抗性和耐受性的抗菌侵扰，它们可用作紫色育种的抗性。导致成人抗屈曲和瘫痪的化合物在抗性品种的睾丸中，并且不太可能是挥发性化合物，而幼虫的死亡率和抗蠕变是由试验中存在的挥发性化合物引起的。 （c）2017 Elsevier Ltd.保留所有权利。
