On June 6th, the World Pest Awareness Day was celebrated, an important occasion that highlights the crucial role of sustainable pest control strategies in agriculture. In a context of growing concern about the excessive use of chemical pesticides and their consequences for human health and the environment, this day served to promote solutions rooted in ecological balance and biodiversity.
One of the most pressing challenges currently facing olive groves—particularly in the province of Jaén—is the rapid spread of the woolly aphid plague. This pest attacks the leaves of the olive tree, weakening its vitality and reducing its productive capacity. In response, many farmers have had to increase the use of chemical treatments, which not only raises production costs but also risks leaving chemical residues in the final product and disrupting the delicate ecological balance of the olive grove.
To address this issue, CITOLIVA has developed AGRO·LIVE Natural Allies, an innovative biological control service that promotes the use of native natural enemies to combat pests in an effective, economical, and environmentally friendly way. Through a technical approach based on entomological diagnosis, the design of environments that favor beneficial fauna, and ongoing monitoring, this system helps control pests like the woolly aphid without relying solely on insecticides. Encouraging the presence of natural predators such as lacewings, hoverflies, and ladybugs helps restore the olive grove’s natural balance and keeps pest populations in check.

The benefits of this strategy are numerous. It significantly reduces the need for chemical treatments, improves the quality of olive oil by eliminating residues, lowers production costs, and helps farmers comply with EU sustainability goals, including the target to reduce pesticide use by 50% by 2030. This approach also reinforces the image of olive oil as a high-quality, environmentally respectful product. With fewer synthetic chemicals, olive groves become healthier environments for wildlife and the workers who maintain them. Moreover, by promoting an ecologically balanced ecosystem, the risk of future pest outbreaks is minimized, making this integrated management model a long-term strategic investment.
Ultimately, the adoption of solutions like AGRO·LIVE Natural Allies marks a decisive step toward a more sustainable future for olive farming. In a region like Jaén, where the olive tree is deeply tied to the landscape, economy, and cultural identity, blending innovation with respect for natural cycles is key to ensuring the long-term viability of the sector. Integrating biodiversity-driven, science-based practices not only helps address immediate threats like the woolly aphid but also lays the foundation for a more resilient agriculture—one that can adapt to climate change, respond to social demands, and increase the value of its final products. Supporting these types of solutions means investing in a new generation of environmentally committed farmers and placing Andalusian olive farming at the forefront of sustainable European agriculture in the 21st century.
