This study aimed to evaluate the enhancement of control by when was planted as a companion crop in cucumber greenhouses. The density and spatial distribution of and parasitized mummies were investigated across three treatment plots: (1) the simultaneous application of and cultivation of (parasitoid-zinnia plot); (2) the application of alone (parasitoid plot); and (3) a control plot (no application of both). maintained low densities in the parasitoid-zinnia plots, while its densities in the parasitoid plots initially decreased but rapidly increased thereafter. The spatial distribution patterns of and parasitized mummies showed similar trends across treatments. However, the parasitism rate of exhibited random distribution in parasitoid and control plots, while showing uniform distribution in the parasitoid-zinnia treatment. These results supported the idea that cultivating alongside cucumber could enhance the effectiveness of as a biocontrol agent against , highlighting the importance of such companion planting in pest management strategies.
本研究旨在评估在黄瓜温室中种植某种植物作为伴生作物时对害虫控制效果的增强作用。在三个处理地块中调查了该植物和被寄生的僵虫的密度及空间分布：（1）同时施用该植物并种植该植物（寄生蜂-百日菊地块）；（2）单独施用该植物（寄生蜂地块）；（3）对照地块（两者均不施用）。在寄生蜂-百日菊地块中该植物保持低密度，而在寄生蜂地块中其密度最初下降但随后迅速增加。该植物和被寄生僵虫的空间分布模式在各处理间呈现相似趋势。然而，该植物的寄生率在寄生蜂地块和对照地块中呈随机分布，而在寄生蜂-百日菊处理中呈均匀分布。这些结果支持了与黄瓜一起种植该植物可增强其作为防治某种害虫的生物防治剂的效果这一观点，突出了这种间作种植在害虫管理策略中的重要性。
