摘要
Ips cembrae是欧洲落叶松(Larix decidua)的一种重要害虫,在过去二十年中造成了局部爆发,随着欧洲落叶松在森林中所占比例的增加,其重要性也日益增加。2021-2023年期间,每个月都将落叶松原木和成堆的树枝放置在森林阴暗处和阳光充足处,以研究伐木残留物上的树皮甲虫种类。成虫出现后,对原木和树枝进行剥皮,分析树皮甲虫的侵扰密度。结果表明,遮光、原木直径和原木上下部分对 I. cembrae 在原木上的侵染密度有显著影响。12 月至 6 月间砍伐的原木上的 I. cembrae 侵染密度高于 7 月至 11 月间砍伐的原木上的 I. cembrae 侵染密度。记录到的所有四种树皮甲虫都受到树枝直径的影响。Ips cembrae主要侵扰阳光照射的树枝,而Cryphalus intermedius则喜欢阴暗的树枝。相比之下,Pityogenes chalcographus 和 Pityophthorus pityographus 的侵扰密度似乎主要受树枝含水量的影响。
期刊介绍:
Agricultural and Forest Entomology provides a multi-disciplinary and international forum in which researchers can present their work on all aspects of agricultural and forest entomology to other researchers, policy makers and professionals.
The Journal welcomes primary research papers, reviews and short communications on entomological research relevant to the control of insect and other arthropod pests. We invite high quality original research papers on the biology, population dynamics, impact and management of pests of the full range of forest, agricultural and horticultural crops.
