In this study, we conducted metabarcoding and incidence analyses to characterise pathomycobiome communities in soil and larval samples from two distinct <em>P. japonica</em> populations. We report the presence of native entomopathogenic fungi (EPF) strains as biomarkers of low-density (LD) stations from São Miguel Island, compared to those of high-density (HD) stations on São Jorge Island in the Azores archipelago. The soil mycobiome at the LD site had a significantly higher Shannon index than that at the HD site. The increased abundance of insect pathogen guilds at the LD site compared to that at the HD site was consistent in both the soil and larval mycobiomes. The most abundant EPF species found in larvae and soil at both stations were <em>Metarhizium anisopliae</em>, <em>Metarhizium frigidum</em>, <em>Cordyceps bassiana,</em> and <em>Metacordyceps chlamydosporia</em>. Statistical analysis showed that four EPF were significantly more abundant in the soil from LD stations than in the soil from HD stations, including <em>M. frigidum</em>, which was also the only taxon significantly enriched in the grubs from the LD station. PCR detection of the biomarker <em>M. frigidum</em> aligns with the higher abundance of this species in both larval and soil samples from the LD site.

A promising but overlooked example of such a strategy is the augmentorium, a tent-like structure designed to trap pests while allowing their natural enemies to escape and multiply. Augmentoria have been successfully deployed to control fruit flies in tropical crops and are particularly effective in small-scale farming due to their simplicity and low cost. Here we explore the potential of expanding the augmentorium strategy to olive production and management of the olive fruit fly, <em>Bactrocera oleae</em>, among other pests. We examine the biological and practical requirements for successful implementation, including the presence of effective natural enemies and integration into farming practices, and investigate size differences between <em>B. oleae</em> and its main parasitoids for optimal net design. Data indicate that the parasitoids present in different regions of olive production worldwide share a similar size difference with the olive fruit fly, suggesting that augmentoria would be applicable across regions. The biggest challenge to implementation may be harvesting infested olive fruits, which is time and labor intensive. We also propose a novel conceptual approach based on the use of companion trees in olive orchards as natural augmentoria, acting in concert with or as an alternative to creating and maintaining tent-like structures. We then discuss further application of the augmentorium strategy for other olive pests, highlighting its adaptability and potential for sustainable pest management across diverse systems.
