“…However, this plant is attacked by different insect groups: sap-sucking, defoliators, stem apex chewing, and the wood-borer (Lemes et al, 2013;Parreira et al, 2014;Silva et al, 2015Silva et al, , 2020. On the other hand, A. mangium is visited and/or colonized by several predators such as ants, neuropteran, spiders, wasps, and others (Silva et al, 2020;Gomes et al, 2023;Lima et al, 2024). These arthropods can be loss and solution sources on A. mangium saplings.…”

Acacia mangium (Willd.) (Fabales: Fabaceae) tree shows applicability in programs to recover degraded areas due to its fast-growing, rustic, pioneer species, with the potential to fix nitrogen. However, this plant is attacked by pests. It is important to know, among them, the most important. This study aims to evaluate the herbivorous insects (loss sources) and their natural enemies (solution sources) on 48 A. mangium saplings. They were classified according to their ability to damage or reduce the source of damage on these saplings using the percentage of the Importance Index-Production Unknown (% I.I.-P.U.). The loss sources Trigona spinipes Fabr. (Hymenoptera: Apidae), Aleyrodidae (Hemiptera), Phenacoccus sp. (Hemiptera: Pseudococcidae), Aethalion reticulatum L. (Hemiptera: Aethalionidae), and Tropidacris collaris Stoll. (Orthoptera: Romaleidae), showed the highest % I.I.-P.U. on leaves of A. mangium saplings. The solution sources Oxyopidae (Araneae), Pseudomyrmex termitarius (Smith) (Hymenoptera: Formicidae), and Brachymyrmex sp. (Hymenoptera: Formicidae), showed the highest % I.I.-P.U. on leaves of A. mangium saplings. The number of Lordops sp. (Coleoptera: Curculionidae) was reduced per number of Brachymyrmex sp.; that of T. collaris those of Oxyopidae and Brachymyrmex sp.; and that of Tettigoniidae that of P. termitarius, totaling 8.93% of reduction of these herbivorous insects (numbers) on A. mangium saplings. These herbivorous insects turn into problems in commercial plantations of this plant since to are related to pests in some crops. These tending ants and Oxyopidae can be important on A. mangium commercial crops because they can reduce the number of these herbivorous insects.

Acacia mangium is well known as a valuable commercial tree species in the Acacia genus. A. mangium was recently found to be self-incompatible (SI), but its SI mechanism is not clear, which has hindered the progress of genetic improvement of A. mangium with strong resistance. To confirm the SI type of A. mangium, pollen germination was observed via fluorescence microscopy at 0 h, 3 h, 6 h, 9 h, 12 h, and 24 h after self-pollination. We found over ninety percent of the pollen grains produced no pollen tube growth on the stigma/style. To further explore the SI molecular mechanism of A. mangium, tests of the transcriptome and metabolome were carried out after self-pollination. Observations of pollen germination after self-pollination using fluorescence microscopy suggested that the SI type of A. mangium is gametophytic self-incompatibility (GSI). A combined transcriptomic and metabolomic analysis showed that DEGs (differentially expressed genes) related to SI (6 S-glycoproteins, 93 F-box proteins, 69 26S proteasomes, 38 calcium-dependent protein kinases/calmodulin and 41 thioredoxin genes) were significantly enriched in six KEGG (sulfur metabolism, tyrosine metabolism, phenylalanine metabolism, butanoate metabolism, and valine, leucine, and isoleucine degradation). Further analysis of these six pathways revealed the enrichment of SI-related DEGs corresponding to succinate, methylmalonate, and 3-hydroxypropane. These three metabolites were significantly downregulated. The analysis of transcripts and metabolites suggested that transcripts of SI-related gene families (thioredoxin and F-box protein) were significantly upregulated under the regulation of transcription factors (TFs) after self-pollination, leading to a decrease in metabolites (such as succinate, methylmalonate, and 3-hydroxypropionate). We also further speculated that TFs (MYB, HB-HD-ZIP, AP2/ERF-ERF, and bZIP) and gene families (thioredoxin and F-box protein) were important factors related to the SI of A. mangium.
