玉米多元栽培中的蜘蛛行会对植物多样性、景观构成和农业周期阶段的不同反应
为提高粮食产量而简化农业生态系统,导致生态系统服务的丧失,如捕食者对害虫的控制。植物多样化在提高蜘蛛等农作物捕食者的多样性方面显示出巨大潜力。然而,在干扰频繁的农业生态系统(如一年生作物)中,植物多样化对蜘蛛的影响是否取决于周围景观和农业周期的各个阶段(即植被、天气和农业实践不同的时期),目前尚不清楚。在此,我们评估了当地管理(植物多样化)、景观(林区)和农业周期对墨西哥玉米多元栽培中主要蜘蛛类群的丰富度和丰度的影响和相互作用。我们发现,作物多样化程度越高(即增加豆科植物和多叶植物),猎地蜘蛛的数量就越多。我们还发现,作物周围的森林面积越大,猎地蜘蛛和猎植被蜘蛛的种类和数量就越丰富。我们发现,农业周期的每个阶段都有不同的蜘蛛丰富度和丰度,在农业周期的初期,地面猎食蜘蛛更为常见,而在作物生长的高峰期,植被猎食蜘蛛和结网蜘蛛更为常见。我们的研究结果支持这样一种观点,即为了培育功能多样的蜘蛛群落,从而提高自然虫害控制的潜力,我们必须考虑到蜘蛛群落在整个农业周期中的高度动态性,共同管理作物内部和周围景观中的植物元素。

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.
