Agriculture in the current century is seeking sustainable tools in order to generate plant production systems with minimal negative environmental impact. In recent years it has been shown that the use of insect frass is an option to be used for this purpose. The present work studied the effect of low doses (0.1, 0.5, and 1.0% /) of cricket frass () in the substrate during the cultivation of tomatos under greenhouse conditions. Plant performance and antioxidant enzymatic activities were measured in the study as explicative variables related to plant stress responses in order to determine possible biostimulant or elicitor effects of cricket frass treatments during tomato cultivation under greenhouse conditions. The main findings of this study indicated that tomato plants responded in a dose dependent manner to cricket frass treatments, recalling the hormesis phenomenon. On the one hand, a 0.1% (/) cricket frass treatment showed typical biostimulant features, while on the other hand, 0.5 and 1.0% treatments displayed elicitor effects in tomato plants under evaluated conditions in the present study. These results support the possibility that low doses of cricket frass might be used in tomato cultivation (and perhaps in other crops) for biostimulant/elicitor input into sustainable production systems.
本世纪的农业正在寻求可持续的工具，以建立对环境负面影响最小的植物生产系统。近年来，事实表明，使用昆虫粪便便是实现这一目的的一种选择。本研究探讨了在温室条件下种植番茄时，低剂量（0.1%、0.5%和1.0%/）的蟋蟀粪便对基质的影响。在该研究中，测量了植株性能和抗氧化酶活性，作为与植物应激反应相关的解释变量，以确定温室条件下蟋蟀粪便处理对番茄种植可能产生的生物刺激或诱导作用。本研究的主要结果表明，番茄植株对蟋蟀粪便处理的反应呈剂量依赖性，这让人联想到毒物兴奋效应。一方面，0.1%（/）的蟋蟀粪便处理表现出典型的生物刺激特性，而另一方面，在本研究评估的条件下，0.5%和1.0%的处理对番茄植株显示出诱导作用。这些结果支持了低剂量蟋蟀粪便可用于番茄种植（或许也可用于其他作物），为可持续生产系统提供生物刺激/诱导输入的可能性。
