以陷阱式粮虫检测器为工具，通过一年观察，初步探明了稻谷散装密闭粮堆中昆虫时空动态及发生规律．结果表明：①密闭粮堆中昆虫群落组成较单一，但食物链式结构十分完整，书虱始终为优势种；②气温上升或下降，昆虫群落的昆虫个体数、丰富度，多样性、均匀度也随之上升或下降，鞘翅目昆虫的分布以上层为主，螨类趋于在上中层活动，书虱在各层分布较均匀；③人为因素对控制昆虫群落变化起决定性作用。 With the trap-type insects and insects as a tool, through a year of observation, preliminarily proved the temporal and spatial dynamics of insects and their occurrence rules in the bulk closed grain piles. The results showed that: ①Composition of insects in the closed piles was relatively simple, but the food chain structure was very complete and the tick louse was always the dominant species. ②Where the temperature increased or decreased, the insect population, abundance, diversity and evenness With the rise or fall, the distribution of Coleoptera insects mainly in the upper layer, the mites tend to move in the upper middle, and the distribution of the ticks in the layers is more uniform. ③ The human factors play a decisive role in controlling the insect community changes.
