Responses of Spodoptera frugiperda and Trichogramma pretiosum to Rice Plants Exposed to Herbivory and Phytohormones.
Article in Neotropical entomology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Damage caused by herbivorous insects and application of phytohormones can activate signaling pathways, which result in greater production of secondary metabolites, increasing plant defenses. This study aimed to evaluate the induced direct resistance (local and systemic) of rice plants caused by herbivorous insects and exogenous application of methyl jasmonate (MJ) and salicylic acid (SA) in the development of fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae). Moreover, indirect defenses through chemotactic responses of Trichogramma pretiosum (Riley) (Hymenoptera: Trichogrammatidae) submitted to the same treatments were investigated. Direct defense was evaluated by measuring weight gain of fall armyworm larvae fed with leaves of plants previously exposed to herbivores or treated with MJ (2 and 5 mM), SA (8 and 16 mM), or control. Indirect defense was verified by chemotactic behavior of wasps in two-choice olfactometer tests to plants exposed to herbivores and evaluated after 24, 48, and 72 h in comparison with undamaged ones, as well as plants treated with the same phytohormones contrasted with the control. The gain of weight was reduced in immature developmental stage of S. frugiperda fed in leaves previously damaged by fall armyworm and in newly formed leaves after damage to the plants, comparing with control. Leaves treated with MJ (2 mM and 5 mM) and SA (8 mM) were less eaten than those not treated. Parasitoids triggered a positive chemotactic behavior in rice plants that had been sprayed with same concentrations. This study showed that rice plants can activate direct and indirect defenses through an exogenous application of phytohormones.
