Plants produce thousands of compounds, collectively called the metabolome, which mediate interactions with other organisms. The metabolome of an individual plant may change according to the number and nature of these interactions. We tested the hypothesis that tree diversity level affects the metabolome of four subtropical tree species in a biodiversity ecosystem-functioning experiment, BEF-China. We postulated that the chemical diversity of leaves, roots and root exudates increases with tree diversity. We expected the strength of this diversity effect to differ among leaf, root and root exudates samples. Considering their role in plant competition, we expected to find the strongest effects in root exudates.In an ecometabolomics approach, roots, root exudates and leaves of four tree species (Cinnamomum camphora, Cyclobalanopsis glauca, Daphniphyllum oldhamii, Schima superba) were sampled from selected plots in BEF-China. Samples were extracted and analysed using Liquid Chromatography-Time of Flight-Mass Spectrometry. The exudate metabolomes were normalized over their non-purgeable organic carbon level. Multivariate analyses were applied to identify the effect of both neighbouring (local) trees and plot diversity on tree metabolomes. The species and sample specific metabolites were assigned to major compound classes using the ClassyFire tool, whereas m/z features related to diversity effects were annotated manually.Individual tree species showed distinct leaf, root and root exudate metabolomes. The main compound class in leaves were the flavonoids, whereas carboxylic acids, prenol lipids and specific alkaloids were most prominent in root exudates and roots. Overall plot diversity had a stronger effect on metabolome profiles than the diversity of local, directly neighbouring trees. Leaf metabolomes responded more often to tree diversity level than exudates, whereas root metabolomes varied the least. We found not overall correlation between metabolite richness or diversity and tree diversity.Synthesis: Classification of metabolites supported initial ecological interpretation of differences among species and organs. Particularly the metabolomes of leaves and root exudates respond to differences in tree diversity. These responses were neither linear nor uniform and individual metabolites showed different dynamics. More controlled interaction experiments are needed to dissect the causes and consequences of the observed shifts in plant metabolomes.

Pesticides have been the most common method for management in the control of Liriomyza trifolli. However, some plants produce substracts with pesticide potential and could be used for the management of this pest. Therefore, the aim of this study was to assess the pesticide potential of tobacco, pepper, castor beans, and garlic extracts in the management of L. trifolli, comparing them to commercial pesticides (Milbeknock® and Vertimec®). The extracts were tested at a concentration of 2.5 mL/100mL of water and pesticides in the concentrations recommended by the manufacturer. The extracts were applied to 10 tomato plants (50 days after sowing), previously submitted to an infestation of L. trifolli for 4 hours. The assessments were initiated one day after pulverization, counting the presence of miners in the leaves, number of alive and dead larvae and the viability of pupae. To assess the effects of the extracts and the pesticides on larval phase, tomato plants with the same characteristics of the previous experiment were submitted to an infestation of the pest for 4 hours. After 72 hours, the extracts and pesticides were pulverized at its respective concentrations. The larval, pupae, and total mortality data were subject to variance analysis, regression, and means were compared by Tukey test at 5% probability. It was found that the pesticide Vertimec® was efficient in the management of L. trifolli both when applied over eggs and larvae. However, among the tested extracts, the garlic extract was more efficient on eggs and larvae, becoming a promising and viable alternative to the management of L. trifolli.
