Yellow stem borer (YSB), is the most destructive and widely occurring pest that attacks rice throughout the growing season. Rice (Oryza sativa L.) is a major staple cereal worldwide, providing essential caloric requirements for more than half of the ...

2024年5月7日 · This study reports the identification of a promising rice line that shows resistance to YSB during vegetative phase of the crop. Bulk segregant analysis and QTLseq analysis of a biparental mapping population identified putative QTL intervals linked to YSB resistance in multiple rice chromosomes.

2019年5月1日 · The efficacies of some next-generation insecticides against the rice yellow stem borer (YSB), Scirpophaga incertulas (Walk.), and their compatibilities with natural enemies were investigated during 2014 and 2015. Three newer insecticides, chlorantraniliprole 0.4% G, dinotefuran 20% SG, and methoxyfenozide 24% SC, and two commonly used ...

2021年6月19日 · Yellow stem borer (YSB), Scirpophaga incertulas (Walker) (Lepidoptera: Crambidae), a major monophagous insect pest of rice, causes significant yield losses. The rice-YSB interaction is very dynamic, making it difficult for management. The development of resistant lines has been unsuccessful a …

2024年7月1日 · The yellow stem borer (YSB), Scirpophaga incertulas (Walker), is a major insect pest that significantly damages rice crop. This study investigates methods to predict YSB populations in rice fields, aiming to develop an early warning system.

2020年9月22日 · The rice striped stem borer (SSB), Chilo suppressalis Walker, and the rice yellow stem borer (YSB), Scirpophaga incertulas Walker, are two of the most damaging pests of rice plant, whose relative crop damage has changed in recent years. Here, we carried out experiments and surveys to understand the potential impact of field flooding on ...

2021年6月19日 · Yellow stem borer (YSB), is the most destructive and widely occurring pest that attacks rice throughout the growing season. Rice (Oryza sativa L.) is a major staple cereal worldwide, providing essential caloric requirements for more than half of the world’s population.

Management of YSB cause crop damage using insect sex pheromone Yellow stem borer ( Scirpophaga incertulas Walker) devastated the crop in all seasons. Larval feeding of YSB from inside stem (Pseudostem) severs central part of tiller at its base resulting in drying of the central whorl and rendering the tiller non productive.

qSB12 YSB是源自具有良好育种潜力的水稻品种 YSBR1 的主要定量纹枯病抗性基因，定位于 12 号染色体上的 289 Kb 区域。 纹枯病（ShB）由 立枯丝核 菌引起，是全球最严重的水稻病害之一。 水稻对ShB的抗性是由多个数量性状基因座（QTL）控制的典型数量性状。 许多 ShB 抗性 QTL 已被报道，但只有少数 QTL 被精细定位。 本研究通过以抗性水稻品种YSBR1为供体、感病品种Lemont（LE）为供体的150个BC 4 回交自交系，在12号染色体上鉴定出一个QTL，其中 …

2022年9月3日 · In this study, SPLAT-YSB (yellow stem borer) at 10 g per hectare with 1000 source points was found to be the most appropriate dose, which evenly saturated the field and helped effectively to control the yellow stem borer.
