1979-80年和1983-84年，采用常年诱捕法，观察了赞比亚Miombo林地头节甲虫和斑腿甲虫的年度飞行方式和多样性。在前一年，窗户诱捕器用短枝木和朱砂原木做诱饵，在后者用枫树原木做诱饵。全年都有甲科和一些种类的甲虫存在，但大多数物种的主要飞行时期恰好与10月或11月的暴雨开始相吻合。1983-84年，这两个科的甲虫的个体数量和捕获种类都明显减少。这可能在一定程度上与枫树原木对甲虫攻击的抵抗力更强有关。尽管在数量和种类上存在差异，但这两个甲科的物种-多度关系在两年中都非常相似。
The annual flight patterns and diversity of scolytid and platypodid beetles in miombo woodland in Zambia were observed by year-round trapping in 1979-80 and 1983-84. In the former year, window traps were baited with Brachystegia and Julbernardia logs, in the latter with Pterocarpus logs. Both families and some species of beetles are present throughout the year, but the major flight period for most species coincides with the onset of heavy rains in October or November. Numbers of individuals and species caught were significantly lower in 1983-84 for both families of beetles. This can probably be related in part to the greater resistance of Pterocarpus logs to attacks by the beetles. Despite the variation in numbers and species, the species-abundance relationships of the two beetle families were very similar in both years.
