Community Composition of Predatory Hybotidae (Diptera: Empidoidea) in Winter Wheat Management Systems

This study examined the community of Hybotidae, a brachyceran family of predatory flies, and their role in natural pest control within different winter wheat management systems (organic, conventional, and hybrid (no chemical synthetic pesticides with optimized use of nitrogen fertilizers)). The semi-field study aimed to explore how agricultural practices, particularly pesticide avoidance, affect Hybotidae communities, thereby contributing to the broader discourse on sustainable agriculture and the conservation of agricultural biodiversity. Results showed fluctuating Hybotidae population densities across different management systems and years, with no consistent link to pesticide application. The complex interactions may be strongly influenced by other factors, such as environmental ones like climate, soil moisture, and prey availability. The results advocate for long-term studies to better understand ecological dynamics and argue for agricultural strategies that balance productivity with environmental preservation.
