Abstract  
The review focused on recent advances and innovations on the use of maize varietal resistance and plant materials in the control of Sitophilus zeamaisMotschulsky. New biological techniques for assessing the resistance of varieties of maize to postharvest infestation by Szeamias were highlighted. It was suggested that routine analysis of plant species is particularly important to cope with the problem of resistance to synthetic insecticides in weevil control. So the paper also revealed the important technical guidelines and scoring system for testing plant materials for insecticidal activity. Effective postharvest insect pest management strategy should form part of the overall crop husbandry for preserving the quality of the produce. Use of resistant varieties is the best approach to overcoming the problems of synthetic insecticides in weevil control. However, breeding maize crop to improve resistance against the maize weevil is associated with some technical limitations. These limitations include lack of inter-specific cross-compatibility, methodological constraints, biotic variation, undesirable genetic linkages, and limited knowledge of genetic bases of resistance. During screening of plant species for insecticidal activities, an untreated control and a reference insecticide whose efficacy in different agro-ecological zones is known should be designated and the plant material should be tested at economically justified doses. The review presented some advances and innovations on the use of maize resistance (including new formulae and scoring systems) in the control of weevil infestation and addressed maize quality and safety after pest-control process. Findings will enhance reorientation of research focus and provide new impetus for the protection of stored maize against Szeamais attack.

玉米和玉米象鼻虫:采后控制害虫的进展和创新

该综述对玉米品种抗性和植物材料在控制Sitophilus zeamais Motschulsky方面的最新进展和创新进行了讨论。强调了评估玉米品种对玉米螟采后侵染抗性的新生物技术。植物品种的常规分析对应对象鼻虫控制中合成杀虫剂的抗性问题尤为重要。因此,本文还揭示了用于测试植物材料杀虫活性的重要技术指导和评分体系。有效的采后害虫管理策略应成为整个农作物生产的一部分,以保持农产品质量。使用抗性品种是克服象鼻虫控制中合成杀虫剂问题的最佳方法。然而,玉米作物育种来提高对玉米象鼻虫的抗性存在技术瓶颈。这些平静主要包括特定的交叉相容性缺乏、方法学限制、生物变异、不良遗传关联以及抗性遗传基础知识匮乏。在筛选用于杀虫活性的植物品种期间,应设定未处理对照组和参考杀虫剂,其在不同的农业生态区域中的功效是已知的,并且应该以经济合理的剂量测试植物材料。该综述介绍了玉米抗性(包括新配方和评分系统)在控制象鼻虫侵染方面的一些进展和创新,并提到了害虫控制后玉米的质量和安全性。研究结果将重新定位研究重点,并为储备的玉米免受S. zeamais攻击提供新动力。
