PLANT-B Leaflet

The present status in citrus culture and honey production constitute indeed a challenging situation for such a farming system that could be described as follows:

  1. Improper use of pesticides: The introduction of honeybee hives in citrus orchards during flowering is a common practice in most Mediterranean countries, facilitating the pollination needs of citrus and providing an income for beekeepers. Nevertheless, in the countries where beehives are introduced in or near citrus orchards, growers and beekeepers may have conflicting interests, mainly from improper use of pesticides which can lead to

    • violations of maximum residues limits (MRLs) and therefore to the decline and prohibition of many export shipments, representing a pivotal problem for exporting Mediterranean countries such as Egypt;

    • adversely affect HB and other pollinating insects as well as communities of other non-target species such as natural enemies, hence influence pollination and biological control services in citrus;

    • pesticide residues in honey, degrading honey quality properties. As a result, a trend of beekeepers going out of business because of low returns is recorded. Improvement of honey quality, traceability, and subsequently, higher prices can reverse this trend.

  1. Plant protection needs of Citrus may differ along the Mediterranean basin: some major pests are common among the countries, but there are also others of local distribution (e.g. Bactrocera zonata is wide spread in Egypt, but is a quarantine pest in the EU). Also, plant protection systems in citrus vary across the Mediterranean countries from organic to IPM and conventional.

  2. Food Safety: The impact of pesticide use on food safety and the environmental sustainability of intensive production systems is currently subject to scrutiny. Indeed, the numerous honeybee mortality cases, linked to contaminant pesticide residues found in dead bees and beehives, is a clear indicator of the high pressure affecting these agro-ecosystems.

Testing Methods

  1. Development of a diversified farming system of citrus and Aromatic Medicinal Plants (AMPs) in combination with apiculture, which would make best use of resources (agricultural land, low pesticide input, endemic honey bee subspecies best suited to Mediterranean conditions, enhancement of pollination & biocontrol), improve (quality, safety, security) citrus fruit and honey produce, and increase the farmers’ and beekeepers’ income.

  2. Combined, citrus-AMPs-beekeeping system, could facilitate a more efficient land use, optimizing pollination services by honeybees and benefiting both the crop and beehive products.

  3. A transition to modern IPM tools, technologies, and practices that enable low pesticide inputs, such as those to be tested in PLANT-B, is to lessen the pressure in citrus cultivation while supporting food security and food safety.

  4. Conservation and exploitation of endemic honeybee subspecies resistant to major honeybee pests such as the Varroa mite are in the same direction.

  5. Assessment of pesticide residues in citrus fruits and honey will ensure the safety of both products for human consumption. Furthermore, the determination of quality, safety specifications and traceability in honey, will help to safeguard its quality and verify its high nutritional value, consistency, and purity.
