| 摘 要： | 采用粮食多功能扦样器对重庆市铜梁国家粮食储备库高大平房仓储粮害虫的发生规律进行调查,结果表明高大平房仓内优势种群为玉米象和书虱,谷蠹和扁谷盗有少量发生,赤拟谷盗的发生很少;害虫发生绝大多数集中在表层和上层;粮仓中央多于四周;温度条件是影响害虫发生发展的主要因素.对储粮害虫种群数量进行相关性分析发现玉米象和书虱的种群数量与总虫数的相关性较高;从垂直分布规律看表层储粮害虫种群数量与总虫数的相关性最高;从水平分布规律看东南区域种群数量与总虫数的相关性最高,且绝大多数达到显著水平. |

| Abstract: | The investigation on population occurrence and distribution of stored-product pests was carried out by grain probe in bulk paddy of large warehouse.The results showed that the dominant species were Sitophilus zeamais and Lipocelis botrychophilus,and subordinate species were Rhyzopertha dominica,Cryptolestes ferrugineus and Tribolium castaneum;The stored grain insects pests occurred mainly in the surface and upside of the grain bulk;and population numbers in center area surpassed that of around.The main reason of affecting population dynamics was temperature.The results of correlation analysis on population dynamics showed that the corelativity between Sitophilus zeamais,Lipocelis botrychophilus and toltal insect numbers was higher,the corelativity between population in the surface and total insect numbers was the highest in perpendicular distribution,and corelativity between population in the southeast and total insect numbers was the highest in horizontal distribution;and the most were significant. |
